Those benefits include accessto a range of government incentives forhiring apprentices.The CAHR Apprenticeship TrainingAnalysis project was designed to help thecouncil address human resource and skillsissues (by identifying human resourcechallenges), develop strategies and recommendationsfor a highly skilled laborforce in the sector and support collaborativeaction by stakeholders.The Canadian automotive industry isCanada’s largest manufacturing sector,accounting for 14% of manufacturingGDP and 23% of manufacturing tradein 2007. It also employs 152,540 peoplein automotive assembly and componentmanufacturing, ranks ninth amongauto producing nations worldwide, andis home to factories of six of the world’sleading automotive producers. In addition,the sector includes a significantproportion (one fifth) of companies withfewer than 100 employees.The Apprenticeship Training Analysisstudy involved interviews with theowners, business managers and humanresource managers of automotive SMEs.In total, the study collected 37 questionnairesfrom the provinces of Ontario andQuebec.Even though layoffs are a reality formany companies, roughly a quarter ofemployers indicated they are currentlyexperiencing a shortage of skilled tradespeople. Current shortages and expectedshortages are most prominent for the followingoccupations: electrical workers,general machinists, millwrights and tooland die makers.Research has demonstrated that overthe duration of an apprenticeship thereis generally a net financial benefit to theemployer. At the same time, there seemsto be a lack of understanding surroundingthe available tax credits available foremployers with apprentices. A numberThe DemandCompact andLow Costof recommended strategic actions for thesector emerged from the analysis:• CAHR and its partners should addressthe perceived and real costs to employersassociated with apprenticeship training,as well as publicize the proven return onapprenticeship training investment foremployers.• CAHR and the country’s federal/provincialgovernments should ensure employersare aware of the available financial supportsfor apprenticeship, including provincialand federal tax credits such as theApprenticeship Job Creation Tax Credit.The AnswerTC Valve SeriesUnmatchedThe most compact valve on the market.− − − − − − − − The Drive & Control CompanyBosch Rexroth Canada490 Prince Charles Drive South • Welland, ON • L3B 5X7 • Phone: (905) 735-0510www.boschrexroth.caOnline configurator, calculator and CAD download:www.boschrexroth.com/pneumatics-catalogElectric Drivesand ControlsHydraulicsLinear Motion andAssembly Technologies Pneumatics Service• CAHR should coordinate meetingswith federal/provincial governments toimprove upon existing tax credits andfunding for apprenticeships.The project was funded by the Governmentof Canada’s Sector Council Program.If you found Renderings interesting, please senda message to firstname.lastname@example.org.Untitled-4 14/14/08 10:44:34 AM

Hearinginstrument wearers often prefer discretionand the target end users’ age group issomewhat overwhelmed and intimidatedby new technology.The Smart Control had to be intuitive,friendly and not intimidating to use andoperate, yet be easily carried in a pocketor purse. The design of the remote waswhittled down to three unique prototypedirections submitted by Evolve that couldbe put into the hands of a focus groupcomprised of users and audiologists.Elastomeric areasprovide additionaltactile gripTHK LM Guidesprovide more than30,000 KM ofoperation withoutmaintenance.U.S. ManufacturingFacility in Hebron, OHLM Guide Types Include:• Clean room • Stainless steel • High temperature • Anti-corrosive• Ceramic • Miniature to large sizes • Earthquake protectionEquipped with patented Caged Technology, where rolling elements areseparated with a synthetic resin cage, our LM Guides operate three timeslonger than any competitor brand. Caged Technology retains grease forcontinuous lubrication and the longest maintenance-free operation in theindustry. Our performance-proven technology also results in the highestspeeds, heaviest load capacities, and the smoothest and quietest LMGuide operation.To learn more, give us a call at 905-820-7800or visit www.thk.com.“Evolve was given all the electronics andphysical mechanical components to packagein 3D CAD Pro/E and STEP file formats,which were easily and flawlessly importedinto SolidWorks, our 3D CAD softwareplatform,” according to Aldo Balatti, designengineering director and plastic applicationsspecialist at Evolve Design Solutions.“Most of the ID (industrial design) conceptualand refinement work was donewith digital hand sketching and digitalrendering sketches produced with Wacomdigital pen/tablets, as well as using solidmodeling and screen rendering captures.The color study images were done withthe help of 3D CAD screen capture imagesfrom PhotoWorks, and Adobe Illustratorand Photoshop,” stated Balatti.“Each one of the 3 proposed unique IDconcepts were exported as fine resolutionSTL files and produced as high resolutionMJM (multi-jet modeling) solid 3D rapidprototyping parts built with 0.0015 in. layersto retain a smooth surface and all the precisionof the features and details as well as toeliminate the hand sanding and finishing postwork. The standard SLA (stereolithography)process was not selected as it only createsparts with 0.006 and 0.004 in. layers.”The choice was a simple and ergonomicshape designed to comfortably fit in thehand and resemble a vehicle remote entrydevice. A finger recess detail was incorporatedat the rear to give the user an identifiablefeature to aid in holding while operatingthe keypad. This is further aidedby the elastomeric user interface touchareas, which give additional tactile grip.“When Evolve was working on finalizingall the final ID detailing, colors, finishesand production specifications, UnitronHearing mentioned (it) would like to have anice cool metallic effect for the main housingbody for the Smart Control remote toshowcase this innovative, technologicallyadvanced new product,” said Balatti.“Since the product has TPE elastomericovermolding user interface touch areas onthe top housing, and while using a metallicpaint and lacquer was an option, it wouldhave meant masking around the elastomericsurface areas which would have addedcomplexity, time, and most likely a higherreject rate and extra cost to the part.“Evolve already had experience usingVisual Effect decorative molded resins fromSabic Innovative Plastics (formerly GE Plastics),so we suggested a more eco-friendlyapproach with using a new Visual Effect EFtechnology system – which only had beenused in Asia at the time,” Balatti added.”Released in 2007, the illuminated andtactile feedback keypad provides all the functionalityat the user’s finger tip. The layoutof the various shape keypad buttons wasdesigned for the user to easily and discretelyadjust settings without looking.The keypad selection covers volumeup/down, program change, telephone andhome button, as well as a “Learn Now”function that gives the end-user the abilityto teach the hearing instrument their preferences.The Scroll wheel on the side controlsUnitron’s unique Comfort-Clarity Balancethat adjusts the HI noise cancellation andspeech enhancement algorithms embeddedin the electronics, explained de Goeij.

November/December 2008dpncanada.comDesign Product News 11Feature: SensorsSensor maker Fraba takes flexible design routeBy James TulkThe Fraba group of companies issupplying the automation industrywith sensor and encoder productsusing a unique, flexible manufacturingsystem that serves small and large volumecustomers equally well and equally quickly.North American orders, small or large,are made to the customer’s specificationsand can be turned around within less thantwo weeks at competitive prices.Fraba knows that when building complexsystems, plant engineers often needmany special items – or perhaps just a few– in a hurry. Its business strategy is to beatthe competition by offering a wide rangeof customizable products, while maintainingthe highest quality standard and shortturnaround times.Fraba believes it offers what the automationindustry craves, because the morespecial characteristics a buyer requiresin a sensor or encoder, the more it canlengthen the time between ordering andreceiving the finished product. Items suchas rotary encoders can have customerdefinedrequirements like mechanical andelectrical interfaces, enclosure materialsand/or environmental protection.Germany-based Fraba, which establisheda North American subsidiary inPrinceton Junction, NJ, in 2000, offersthree lines of products for the industrialautomation market: ‘Posital’ brand absoluterotary encoders and inclinometers;‘Intacton’ optical velocity and positionsensors; and ‘Vitector’ contact sensing‘safety edges’, used to reduce the dangerof collisions between automation equipmentand other objects. All products aremanufactured using a just-in-time productionand delivery concept. For ChristianFell, Fraba VP in charge of the encoderbusiness in North America, the key isthe highly flexible and responsible manufacturingprocess. “We currently havelead times of 10 business days for ordersoriginating in Canada or the U.S., comparedto up to six weeks for some of ourcompetitors.”Fraba’s made-to-order strategy is builton two key pillars. First, the sensors arebased on a highly modular design. Forexample, all models in the Optocode familyof absolute rotary encoders employan optical rotation measurement systemthat can sense angular displacements assmall as 1 part in 65,536. If required, arotation counter with a range of 8192turns can be added. This combination ofresolution and range can meet the needsof most industrial automation applications.Thanks to the modular design ofthe encoders, measurement componentscan be combined with a variety of electricalinterface modules: Bit-parallel, SSI,Profibus-DP, CANopen, DeviceNet orFraba Posital: Absolute rotary encoders and inclinometersagainst the background of a new manufacturing site.Industrial Ethernet are all supported, aswell as a variety of connector types andmechanical interfaces.For applications where smaller componentsare needed, ‘Magnetocode’ rotaryencoders are a mere 36.5 mm in diameter.“Overall, the ‘Posital’ portfolio offers over1000 different encoder configurations,with thousands of other combinationsavailable for the asking,” explained Fell.A range of accessories are also available,including wire draw adapters, couplingsand heavy-duty housings.The second pillar of Fraba’s strategyis flexible manufacturing, exemplified bythe company’s new manufacturing facilityin Slubice, Poland on the German border– less than an hour’s drive from Berlin.This facility is housed in a striking newbuilding that resembles a large aluminumdisk lying flat on the ground (inset photoabove). The interior layout is highly functional,with support and storage areaslocated around the circumference of thebuilding, while the production areas aregrouped near the centre. This means thatthe assembly workstations have quickand convenient access to supplies andresources while the workstations themselvescan be rapidly reconfigured tomeet changes in the production schedule.Workstations are equipped with computerterminals, barcode readers and testequipment that support a data-drivenAssembly workstation in Fraba’s plant.production system. Specifications fornew orders are routed directly to theworkstation computer terminals. As newitems are assembled, a full history of theprocess – from batch numbers of subcomponentsto the final test results – isrecorded in a central database. This supportsboth rapid order fulfillment andend-to-end quality assurance through avirtually paperless process. Careful attentionto electro-static discharge controland 100% testing of finished productshelps ensure product quality.James Tulk is with PR Toolbox in Toronto(firstname.lastname@example.org).www.fraba.comFACED WITHDIFFICULT AND CRITICALSEALING CHALLENGES?®INSIST ON SEAL MASTERINFLATABLE SEALSTODAY…SLEEP BETTER TONIGHT!WWW.SEALMASTER.COMDESIGN ASSISTANCE PROGRAM“They’reDeucedlyClever”SEAL MASTERCORPORATION368 Martinel Drive, Kent, OH 44240-4368 USA800-477-8436 • 330-673-8410 • FAX 330-673-8242We’ve got it covered!We’re your number one source for stock components.Over100,000,000components instockImmediateshipmentCustomcomponents toyour specsAll types ofsprings, washersand fastenersCheck SPEC ® online atasraymond.com/specFor immediate assistance, call 800.263.4256 or fax 814.664.0312©2008 Barnes Group Inc.

14 Design Product Newsdpncanada.com November/December 2008Feature: EnclosuresChoosing an electrical enclosure forharsh washdown environmentsBy Kenan HanhanMeeting strict government regulationsand assuring customers ofexceptional product quality canbe a daunting task – especially in industriessuch as food and beverage, where contaminationposes a significant risk to equipmentand customers. To combat this threat,today’s washdowns have been intensifiedup to 1200 psi, and harsher chemicals areemployed to maintain sanitary conditions– thereby reducing the risk of product damage,contamination or corrosion.While these measures will help keepcritical machinery clean and contaminantfree,they can prove detrimental to sensitiveelectrical and electronic equipmentthat are not properly protected. And likeall equipment used in these applications,the electrical enclosure selected must bedesigned and constructed to maintain asanitary work environment and minimizeServoLiteServo Performance - Stepper SimplicityTo maintain sanitary conditions, demanding foodand beverage applications require high-pressurewashdowns and harsh cleaning chemicals, which coulddamage electronic controls if they are not properlyprotected.the probability of a food-borne outbreak.To promote sanitary conditions and optimizeproduct safety, only enclosures withthe appropriate NSF certification shouldbe installed. The NSF/ANSI 169 standardspecifies the essential design criteria forfood equipment and devices. Choosingan enclosure that is NSF/ANSI 169-certifiedaffirms that key enclosure attributes –including construction and quality, design,sealing and gasketing, and hinging andlatching – promote sanitary conditionswhile protecting electrical equipment inchallenging washdown environments.To withstand harsh chemical washdown,enclosures used in these applicationsshould be constructed of a nonabsorbentmaterial – such as Type 304and 316L stainless steel – to resist moistureingress. Adding a #4 finish will ensurecontaminants are successfully removedfrom the enclosure surface during washdown.Plus, selecting an enclosure withsmooth welds eliminates the risk of contaminantsinfiltrating tiny nooks and cranniesin the enclosure’s design.For optimal quality, consistency andrepeatability, manufacturers should selectan enclosure that has been producedusing automated manufacturing processes.Automation minimizes product variationfrom order to order, affirming that eachenclosure will meet the same stringentapplication requirements. This method isadditionally beneficial for producing enclosuremodifications, since automated processeshelp ensure these modifications areperformed consistently and accurately.Enclosure design can make the differencebetween an effective and an insufficientwashdown. Common enclosure-relatedproblems include washdown solution poolingon the enclosure, contaminant entrapmentbetween a wall and a wall-mountenclosure, and unreachable, recessed areascreate by free-stand enclosure floor stands.These challenges can be addressed inseveral ways. Wall-mount enclosure standoffsprovide access to the back of theenclosure, allowing washdowns to removeAn enclosure with a sloped door flange with troughcollar and shielded bullet hinge will facilitate runoff inwashdown conditions.Different operatingmodesServoLite: closed loop Holding torque from 0.5 Single and multi-axisincludedto 9.0 Nmsystems“Plug & Work” Handling SolutionsThe ServoLite single axis position controller operates stepper motors with positionfeedback in closed loop. The key benefit is higher “servo-like” performance whichcannot be obtained with conventional stepper-motor controllers. ServoLite seamlesslyintegrates with single and multi-axis handling units. The resulting solutions areunmatched in terms of performance characteristics versus cost.Festo Inc.Tel: 1 877 GO FESTOFax: 1 877 FX FESTOinfo_ca@festo.comwww.festo.cathese hidden contaminants more easily.Using a smaller, specially designed standor leg footprint can minimize the difficult-to-cleanareas beneath a free-standenclosure’s floor stands, reducing contaminantaccumulation. To prevent washdownsolution pooling, select an enclosure witha 20º sloped top design combined with asloped body door flange trough collar andsloped door edges. These features directwashdown effluent away from processingequipment for optimal sanitation.While choosing the optimal enclosureconstruction and design for washdown environmentsis essential, selecting a high-performanceseal or gasket is another critical componentto ensuring an enclosure’s success.Seals, gaskets and their adhesives must beconstructed of materials that are compatiblewith stainless steel, since this is typically thespecified enclosure material in these applications.Also, these seals, gaskets and adhesivesmust withstand harsh, high-pressurewashdowns and be checked periodically forresiliency loss and compression.For further information on our customized solutions – contact us today!Kenan Hanhan is Vertical Market Managerfor Hoffman.www.hoffmanonline.com

November/December 2008Feature: Enclosuresdpncanada.comDesign Product News 17Cooling industrial enclosures with filter fan designsBy Mark MaddenOne of the most important considerationsin choosing a fan foryour cooling needs is whether theambient, or surrounding air, is cooler thanthe desired temperature to be maintainedinside the enclosure. If so, a filter fan maybe right for your application.We have decided to use filter fansbecause we want to protect our systemfrom dirt and other impurities– one of the reasons thatwe have our system in anenclosure in the first place.Now that we have determinedthat we are goingto use filter fans, we needto decide on the requiredairflow.(We can do this with computationalfluid dynamic software using Therm, ageneral sizing program available as a freedownload at rittal-corp.com/software).A filter fan consists of the filter housing,a motor and the fan blades. The motorturns the fan blades, and the housingdirects the flow of air. One can think ofthe spinning fan blades pushing the airfrom the front to the back of the filter fan.This pushing creates pressure, and at a certainpressure, the fan can move a certainamount of air known as air displacement,or airflow. The pressures and airflows areImpedance andback pressureare factorsdirectly related to each other.Unimpeded airflow is how much aira fan can move if it is sitting on a table.Although a popular measure of performance,this is not a very good indicationof how much airflow will be generatedwhen the filter fan is mounted in an enclosure.Along with back pressure, anotherimportant factor to take into considerationis impedance. Impedance is the resistanceof the air to flow. When we put thefilter fan on the table andrun it, there is very little orno impedance, resulting inunimpeded airflow.In most application scenarios,there is a fan, anenclosure, and an outletlouver that the fan has topull the air in, pushing against all of the airthat is inside the enclosure, and then forcingthe air out through the exhaust louver.Since pressure and flow are related, the fanslows, reducing the flow and increasingthe pressure.To show how a fan operates as flowand pressure change, we have a diagramcalled a “fan curve.” The pressure is representedon the Y-axis and airflow on theX-axis.To be completely accurate, impedancehas to be factored in. To do this, an impedancecurve can be placed on the samechart as the fan curve. The point where thetwo curves intersect is the actualairflow.Is there a benefit to using twofans on an enclosure instead ofone? Since airflow and pressureare related, there should either bemore airflow or more pressure.Depending on where the fans aremounted, both are true.Series operation can be definedas using multiple fans in a pushpullarrangement. In this case,the impedance of the system isreduced because the exhaust fanis lowering the pressure insidethe cabinet. This allows the systemimpedance to move up the intakefan’s fan curve line, which leads to moreairflow.It doesn’t double the airflow, however,because the highest possible airflowa filter fan can have is unimpeded airflow.Despite this limitation (present with anyfan), series operation does get the airflowcloser to the unimpeded flow in a heavilyimpeded system.Two or more fans blowing together sideby side is referred to as “parallel operation.”In this configuration, if there is lowto medium impedance, both fans are ableto provide close to twice the airflow of asingle fan.In order to protect the proper functioningof electronic components, heat mustbe dissipated from the enclosure, and thisUnimpeded airflow curve (red line) and fan curve withimpedance (blue line). Inset: air displacement with outletfilter including standard filter mat.can be done in a variety of ways including:natural convection, fans, air-to-air heatexchangers, air-to-water heat exchangers,and air conditioners. If fans are to be used,it is important to consider how much airflowis needed, and how much airflow theproposed filter fan solution will actuallyprovide.Mark Madden is the lead ApplicationsEngineer for Climate Control productsat Rittal.

18 Design Product Newsdpncanada.com November/December 2008Feature: Power TransmissionBearing the challenges of modern truck designHeavy truck designers and manufacturersin Canada and the U.S.are all talking about the latesttrend that promises to both improveand challenge the trucking industry. Itincludes finding new ways to reduceengine emissions while maximizing fueleconomy.In Canada, the industry is workingtogether to popularize “enviroTrucks”that reduce fuel consumption and greenhousegas emissions by using the latesttechnologies. And in the U.S., truckbuilders are focused on meeting newEnvironmental Protection Agency (EPA)regulations that address diesel engineemissions and idling times.One way OEMs in the industry arebuilding better trucks is by challengingsuppliers to design components and subsystemsthat reduce weight and improvefuel economy. When those suppliers canalso provide products that lower cost,reduce inventory and simplify installation,partnering with them isn’t just goodfor the environment – it’s also good forbusiness.At The Timken Company, engineersare constantly looking for waysto improve overall system performancethrough smart bearing design. One oftheir recent innovations for trucking andoff-highway pinion and differential shaftsis the threaded cup bearing.The threaded cup was originallydesigned to eliminate early service warrantyproblems occurring on heavy truckdifferential shafts, when the originallyspecifiedtransition cup fits would comeloose and turn, causing the housing towear. The threaded cup design eliminatesthe turning cup, and its design alsoresults in more benefits – it can improvefuel economy, reduce parts and inventorycosts, and simplify differential shaftassembly.“On differential shafts in the traditionalbearing cup design, two standardtapered-singlebearings are split-fit in thehousing using threaded cup followers forAn integrated threaded cup combines the TS cup, threaded cup follower and anti-rotational locking device into onecomponent, reducing cost, weight and complexity.bearing and gear mesh adjustment. Thedesign also included separable lockingdevices with fasteners to prevent the followersfrom unthreading,” said GlennFahrni, principal application designer atTimken. “Because the differential shaftrequires an adjustable cup, the cup fitsmust be originally-specified as partiallyloose in the housing. This causes the cupsto eventually work themselves loose rotationallyuntil they begin wearing on thecup adjuster and housing.”To solve these problems, Timken integratedthe threaded cup follower, taperedsinglecup and rotational locking deviceinto one component – the threaded cupassembly. The threads were moved fromthe old cup adjuster onto a portion of thecup outside diameter (OD).“To provide an anti-rotational feature,we weld a low-carbon sheet metal ringto the carburized cup’s backface,” Fahrnisaid. “Timken has been issued a patent forthe threaded differential bearing cup.”By combining the individual componentsof the traditional cup design intoone, the threaded differential cup offersless complexity because there are fewerparts to inventory and handle duringaxle assembly. The result is easier andquicker assembly and less time spentadjusting the bearings and gear mesh.Threaded cup designs also help OEMsreduce fuel consumption and maximizeengine performance by creating less dragcoming from the axles.The threaded cup features Timkenhigh-performance bearings, sometimesreferred to as P900. The bearings featureultra-clean steel, which reduces the riskof fatigue spalling and bearing failure,as well as smoother surface finishes thatimprove lubricant film thickness, resultingin up to 4x the predicted bearing lifecompared to standard finishes.Special internal bearing profiles alsospread the load more evenly across thebearing contact surfaces, keeping contactstress to acceptable levels.“By combining clean steel, smoothersurface finishes and special raceway profiles,we’ve been able to integrate severaltraditional components into the threadedcup bearing, making it capable of handlingheavier loads without making thebearing bigger or heavier,” Fahrni said.“It’s what we call power density –increasing the bearing capacity-to-weightratio, so that a smaller bearing can carrya greater load.”Since the integrated threaded cupweighs less than the traditional design,and also diminishes the overall housingwidth needed to support it, axle weightis saved. Fahrni noted the overall weightsavings help contribute to fuel economyand reduced engine emissions.Currently, Timken engineers areinvestigating the usage of a threaded cupbearing on the pinion shaft.“On the pinion shaft, to correctlyadjust the traditional pinion bearingsthe axle OEM has to keep anywherefrom 40 to 55 different sizes of a variablelength cone spacer at their assemblystation,” Fahrni said. “How the pinionhead and tail bearing tolerances stack updetermines which spacer size is used.”According to Fahrni, rolling torque isused as the bearing setting measurementmethod, and the tight-fitted cones areclamped through the spacer with a nuttightened to a very high clamp torque.If the wrong spacer size is initially used,you have to teardown the pinion shaftand rebuild with another spacer size.Teardowns involve loosening the nutand pulling off the outer tight-fitted cone– a time-consuming process. Sometimestwo rebuilds are required,” Fahrni said.“A threaded cup on this shaft wouldresult in only one fixed-length cone spacersize being needed and no productionteardowns or rebuilds.”This article was contributed The TimkenCompany.www.timken.comMidget FuseTerminalThe World of Bearings and Power Transmission...Rated 120V, 32A, this” x 1 ½” fuseterminal includes a blownfuse indicating LED.Interconnecting pins areavailable to make 2 and 3pole units.Visit our website atwww.emphatec.comand check out thespecial introductoryprice.Our size and flexible structureenables us to respond rapidlyto your requests.

When accelerating,the hydraulic pressure reservoir is controlledelectronically to release the pressureand it relieves the load on the dieselengine. As a result, the engine consumesless fuel, generates less exhaust gases,and functions more quietly.The compact Rexroth HRB is idealfor use in various commercial vehicles.The HRB can be integrated and evenretrofitted in the chassis as an add-onsystem, without major modifications.The system reduces fuel consumptionby up to 25% in vehicles used for veryshort distances such as urban buses,garbage trucks, fork lift trucks or deliveryvehicles driven in city traffic. FuelRexroth hydrostatic regenerative braking system (HRB) reduces fuel consumption by up to 25% and can beretrofitted as an add-on system even in vehicles without hydraulics.consumption can also be reduced considerablyin other commercial vehiclesand trucks used for intercity service.Each time a driver brakes, the HRBsystem stores energy which would otherwisebe lost. The hydrostatic hybriddrive functions almost maintenancefreeand wear-free compared withelectric hybrid drives. For example,it is not necessary to regularly changethe battery. In addition, the HRBalso improves the acceleration of thevehicle. The additional drive energyallows vehicles to be equipped withsmaller diesel engines and thereforefurther reduce fuel consumption andemissions.All Rexroth HRB components arebased on standard components fromthe manufacturer’s current productportfolio.

20 Design Product Newsdpncanada.com November/December 2008Feature: Power TransmissionRight angle gearbox kitdrives canopy closuresSteve Ostrowski was at his wit’s endtrying to find the exact componentthat would enable his ShadeFX canopysystem to be easily installed and ableto integrate with the system’s motor witha drive beam. Ostrowski, a partner withShadeFX Canopies (shadefxcanopies.com)in Toronto, manufactures retractable canopiesfor decks and patios utilizing a patentpendingmonorail drive that does not jamor misalign.Ostrowski and his partners considereda number of options, including a simplesocket engagement mounted to the beam,which had a belt drive, and drove thewheels at one end of a caterpillar loop, butthe mechanism was too cumbersome tooperate. Ostrowski harkened back to hisoriginal goal: to make the system hasslefreeand easy to install.“A critical element in the design is thatthe canopy is driven by a monorail beamthat supports the canopy in the middle,”Ostrowski said. “This process eliminatesthe need for the tracks to be aligned, andallows it to be mounted to a wood framethat could shift and twist over time.”The solution also had to be compact, yetcost-effective. With little options to choosefrom, Ostrowski did what most astute businessmendo: he turned to the Internet in hisquest for a solution. “I didn’t really knowwhat it was I was searching for,” he said. “Isearched dozens of terms. Somehow, after10 hours of dutiful Internet sleuthing I gotthe ‘compact right angle transmission’ Iwas looking for.”The right angle gearbox (black area) from TorqueTransmission assembled into the ShadeFX canopysystem.If you’ve paid one centfor a direct materialssourcing solution,you’ve spent too much.With MFG.com, you get everything you need from a sourcing solution, including directaccess to thousands of qualified suppliers … absolutely free.

Theywere the ones that had to make it happeninside of 3 weeks for our product launch.”Faced with the dilemma of finding amethod to accurately move the canopy system’sdrive beam, Torque Transmission’sengineers offered a custom right angle gearbox slightly modified to meet the customersexact requirements, two timing pulleys,one idler shaft, and two keys as the solutionto Ostrowski’s problem, thereby simplifyingordering and inventory. In addition,all the components are shipped as akit with a single part number in a sealed,compartmentalized container.“Torque’s right angle gear drive allowedus to mount our long slim tube-motor parallelto the drive beam,” Ostrowski said.“That made the drive beam one integralunit with the motor and we knew we tookthe design to the next level of simplicity.Also, a simple extended shaft on oneside of the gearbox significantly improvedease of manufacturability and allowed usto take another 1/4 in. out of the motorstand-off dimension.”Gary Rusnak of Torque Transmission’smarketing department said TorqueTransmission’s standard array of drives ineach right angle gearbox line satisfies a widespectrum of application requirements.“Torque Transmission has a gear driveand speed reducer to fit the needs of ourcustomers,” Rusnak said. “If we don’t,we will modify or custom design a speedreducer for their application.”“Our first order was for 10 CustomRAB-1 Right Angle Gear Drive and pulleykits at a cost of $123.00 each,” Ostrowskisaid. “We plan to use at least 100 morekits this year.“The bigger value to us is that we laterfound out that Torque Transmission alsodoes a significant amount of business inmaking timing belt pulleys so we were ableto reduce three suppliers down to just one– Torque Transmission,” Ostrowski said.This article was contributed by TorqueTransmission.www.torquetrans.comUntitled-6 Untitled-1 1 18/29/088/22/08 10:04:29 12:54:20 AM PM

Meanwhile,engineers who take full ownership of theirdesigns and work alongsidemanufacturing andprocurement can be seenas being meddlesome.It is these engineers,however, who are essentialto success given the realityfacing Canadian manufacturers.The engineeringdepartment cannot do it alone, however,and must be backed by an executive teamthat actively promotes continuous improvementand cost reduction initiatives fromAlpha_MayJune.indd 1Every company’sgoal is to speedup new productdevelopmentinitial conception right through to finishedproduct.As stewards of design, engineers mustbalance quality and selling features withprice, but they must also be aware ofhow ease of manufacturingand assembly contribute tolowering costs. That beingsaid, companies shouldnever endorse cost-cuttingmeasures at the expense ofquality or safety.Instead of simply reducingprices and sacrificing marginsto compete with low-cost competitors,companies should concentrate on loweringinternal costs by streamlining product development,manufacturing and procurement,Vicone High Performance Rubberhas just launched its Rapid RubberPrototype Program for designers toget molded rubber parts in 5 to 15days, depending on part complexity.The company’s rubber specialists assesssubmitted drawings and can provide aquote within 12 hours.thereby allowing them to lower prices withoutsacrificing profit margins.Every company’s goal is to speed upnew product development (bring productsto market faster), minimize idle time, lowerproduction cycle times and maintain a costefficient inventory. Process innovation andcollaboration between engineering, manufacturingand procurement is essential tomaking this happen. Minimizing design5/30/08 10:42:31 AMflaws fromthe prototypestage, andensuringtheyare fixed before moving on tofull scale production is one component.Another is having a clear understanding ofwhat those design revisions mean for bothmanufacturing and procurement.Product Lifecycle Management (PLM),pioneered by the American Motors Corp.after its years of declining sales throughoutthe1970s, is an internal principle centeredon product development and proper documentationof engineering changes withina common database. PLM is also nowresponsible for the introduction of CAD(computer-aided design) software, whichallowed engineers to make immediatechanges to designs.PLM is a company-specific philosophyand not a simple cut and paste solution forall. The over-arching idea is to have a systemin place that ensures the continuous reportingand measurement of all engineeringchanges as well as all design and manufacturingimprovements. PLM is a continuousfeedback loop. Manufacturing reports backto engineering on production and assemblycycle times. Engineering reports back topurchasing on potential changes in materialand parts, and the resulting impact thosechanges will have on current inventory.Manufacturing and assembly cycle timesare driven largely by a product’s design.Suppliers with quick turnaround timeson materials and parts are an essentialcomponent, as they help to reduce inventorycosts and improve product to marketlead times. Engineering can play a pivotalrole in both these areas by working withpurchasing and QA (quality assurance)to create a short list of preferred suppliersand by taking an active role in witnessingand discussing how the end product will bemanufactured and assembled.To accomplish this, companies may usean Engineering Change Notice (ECN) asa way to initiate and document changes.These ECNs allow engineers to changeprocesses and instructions for productionand assembly, review quality issues, andultimately reduce downtime and rejectedproducts. They can also be used to helpease the financial burden of unused oroutdated parts in inventory. This is accomplishedby documenting what currentinventory of materials and parts can stillbe used prior to implementing any designrevisions. Purchasing and the appropriatesuppliers are then made aware of the needto change the part on future orders.Documentation of ECNs along the PLMprinciple provides an historical reference tohelp avoid problems with future productdevelopment, inventory management andmanufacturing. With a history of problemsolving and cost cutting measures properlydocumented, the motivation to continuereducing costs should spread throughoutyour entire organization.This article was contributed by ViconeHigh Performance Rubber.www.vicone.ca
November/December 2008Feature: Enterprise CADdpncanada.comDesign Product News 23Reduce rework with better design reviewsWhen “Lefty” Pearson inventedthe first automated beverage carriererector in his garage in 1955,Pearson Packaging Systems (pearsonpkg.com) was born. Today, Pearson is one ofthe largest manufacturers of secondarypackaging machinery in the world.Pearson recognized that digital prototypinghad the potential to transform its designand design review processes. The companyadopted Autodesk Inventor Professional asits core design application because it producesan accurate 3D model that validatesthe form, fit and function of a design beforeit is physically built.With Inventor, designers can easily see andremove potential interferences and designflaws as they work. This minimizes theneed for costly and time-consuming physicalprototypes and helps reduce the risk ofengineering changes after the design hasbeen sent to manufacturing. Additionally,Inventor allows the company to automaticallypublish models as easily sharable DWFfiles at any stage of the design process.Prior to using Autodesk Inventor designand Autodesk Design Review visualizationDocumentationimprovements can alsobe realizedsoftware, Pearson depended on 2D designtools and design reviews. Designers createddrawings of machines based on customerspecifications, carefully checking for interferencesbetween parts of complex assembliesalong the way. Iterations progressed slowlyas Pearson and its customers exchangedand reviewed drawings. Often, customerslacked the expertise necessary to understandkey aspects of the designs. So even thoughPearson’s teams spent significant timeexplaining the designs, customers sometimesapproved machine designs that were notexactly what they wanted, and as a consequence,they frequently requested modificationsto machines after manufacturing.After receiving their packaging machines,customers got product documentation inthe same potentially confusing format.When parts needed replacing, some customersfound it difficult to match theparts they needed to the part numbers inthe drawings. Pearson’s customer serviceagents patiently worked with customers toprovide the help they needed, but the processwould have been greatly accelerated bymore dynamic product documentation.The move toward paperless manufacturingsaves time by making it easier to manageand share designs.“Sometimes we spent more time explainingwhat customers were looking at thanthe pros and cons of design features,”said Greg Purviance, Pearson’s IS managerand a long-time designer. “Customersoften approved designs, and then requestedmodifications after assembly. We do whatwe can to ensure customer satisfaction,but the costs of post-manufacturing modificationsadd up. It’s much more efficientto make changes to designs instead of tomachines.”Explained Matt Dykhouse, a mechanicaldesign engineer at Pearson: “with a digitalmodel or prototype, you can test mechanismsbefore building them. Take linkagesand assemblies, for example. You can testconstraints and the range of motion ofparts in relation to the whole machine inways that are virtually impossible with 2Ddrawings.”When the initial design process is complete,Pearson and its customers have adigital prototype to review. Dependingon customer preference, they either walkthrough the prototype with Pearson’sdesigners in Inventor using web-conferencing,or Pearson sends customers a DWF filethat they can review with Autodesk DesignReview. Autodesk Design Review is a free,downloadable application that allows usersto view and mark up 2D or 3D DWF fileswithout having the original design softwarein which the DWF file was created. WithDesign Review, Pearson’s customers areable to spin digital prototypes, zoom inon features and individual parts, and seeexactly what they are approving.For Pearson, the advantages of digitalprototypes extend beyond design anddesign reviews. Employees on theshop floor and end-users of the company’sproducts also benefit. Whenit’s time to assemble a machine,workers on the shop floor viewa model of the design on largescreendisplays using Design Review.They can measure parts, zoom inon complex assemblies, and viewdesigns from every angle. They caneven mark up designs with detailedinstructions for less experienced coworkers.Wh“Being able to share models withAutodesk Design Review takesthe advantages of digital prototypes tothe shop floor,” said Dykhouse. “Ourassemblers have come to appreciate digitalmodels and Design Review.

The company’srevolutionary TurnKnife Systems forchipping and lumber production, its innovativeScanChip Analyzer, its industryleadingdebarking systems and groundbreakingPartnerChip and service optionshave kept it on the cutting edge of thelumber and pulp and paper industries.“For us, the possibility of gettingan order is often driven by how quicklywe can deliver. These days, this isas important as the technical merits ofthe solution,” explained Ian Zinniger,engineering manager for Iggesund Tools’Canadian operation.Headquartered in Iggesund, Sweden,the company also has North Americanoperations in Laval, QC, and Oldsmar,FL. Engineering is done at all three sites,while production takes place principallyin Sweden.In the past, the three engineering sitesprimarily worked independently. In fact,at times each site designed its own versionof the same part. Although this wasinefficient, it was safer to work that waybecause the company had limited centralizeddata management.“You couldn’t be sure, if you wanted touse a part designed somewhere else, that itwouldn’t be changed later on without yourknowledge,” explained Zinniger. Therewas a similar problem sending data fromthe three engineering sites to the productionfacilities. Without good product datamanagement (PDM) functionality, it wasdifficult to ensure that production workedwith the latest revisions of the data.After evaluating the available options,Iggesund Tools found that NX andTeamcenter software from Siemens PLMSoftware best met these criteria, deliveringa managed development environmentcapable of handling the complexityof the company’s designs along withpowerful data control.From the design perspective, the companyhas seen many advantages to workingin NX. “With NX we gained a considerableamount of functionality that hasbeen extremely helpful in cutting designThe combination of NX 3D CAD and Teamcenter PDMsoftware has permitted Iggesund Tools to become moreefficient and customer responsive.EVERY PLANT NEEDS A PARTNER TOKEEP THINGS BUZZINGPepperl+Fuchs, Inc.Twinsburg, Ohio330.486.0001www.pepperl-fuchs.comWe’ll work hard to keep your plant buzzing usingthe most advanced sensing technology…all froma single-source partner.

With NX, they can now do that.The main advantage, however, has beenthe ability to automate routine productdesign (which includes tasks such as modeling,drawing creation, engineering checksand implementation of engineering changes,all the way through to release.) “In thepast, routine product design could takeup to two to three weeks,” said Zinniger.“Today, using the knowledge capture andautomation capabilities within NX, it canoften be reduced to two to three days.”Zinniger has run the numbers and reportsa consistent two to threefold decrease incycle time since the Canadian operationstarted doing routine design in NX. Thetime saved is not the only value, however.“You can put know-how into the automationtools, and that cuts down on thetraining of designers,” Zinniger added.“This is especially important when youhave multiple sites and you have to teachdesign methods and standards across differentcontinents, languages and cultures.Creating these automation tools in NX andthen sharing them is much more efficient.”Teamcenter delivered the multi-site datacontrol Iggesund Tools was looking forfrom a PDM system. “We can move databetween sites with the confidence that upto date versions are always being used,”Zinniger said. One important outcome ofthis is an ability to better leverage the workof the three engineering groups. “In thepast, one site didn’t take advantage of existingcomponents designed by another sitebecause they couldn’t be sure they wouldn’tbe changed without their knowledge.”This article was contributed by SiemensPLM Software.www.siemens.com/plm
November/December 2008dpncanada.comDesign Product News 25Feature: Enterprise CADMosaic’s mine sites dig into benefitsof document managementThe global agricultural industry isfaced with an escalating demandfor potash. The Mosaic Company,one of the world’s leading producers ofconcentrated phosphate and potash cropnutrients, is engaged in a long term potashcapacity expansion plan. In this growingeconomy, the challenge facing theengineers at Mosaic’s Esterhazy miningoperation is how to manage, track andshare the growing numbers of drawingsand documents that are created and sharedthroughout the organization at every stageof a plant’s lifecycle.Terry Heal, mechanical project engineer,Willis Pushka, electrical draftsman,and Ed Ellinger, mechanical draftsman,in Esterhazy, Saskatchewan, first implementeda document management solutionfrom 1993 to 2003 – until it no longersupported the latest upgrades to theirAutoCAD tools.“We wanted to find the drawings, havea secure safe place to put them and ifsomething went wrong we wanted tobe able to access those drawings on ournetwork without them being encrypted,”said Pushka. “The number one thing wewanted was a program that kept all thefiles in a native format.”Their search led them to SynergisThe Mosaic Potash Esterhazy K-2 plant.Software, the developers of Adept documentmanagement. Heal explains theirreasons for selecting Adept.“Moving forward with Adept we certainlywanted to have stronger controlover the drawings. We wanted to eliminatethe possibility of two people working onthe same drawing simultaneously, to trackrevisions, and to maintain a history ofthe drawing,” Heal explained. “Adept’s‘Sign In’ and “Sign Out’ features alongwith its ability to restrict access to onlyauthorized personnel were additional considerations.”Another reason for selecting Adept,was Synergis Software’s assistance withthe implementation. In one week, Pushkaand Ellinger working with a SynergisSoftware Application Engineer installedAdept on MySQL server for optimumperformance, design the Adept databaseand specifications for the Library Cards– which contains metadata about eachdocument that needs to be tracked – andtrain the users.“I think it has been working awfullywell and the implementation process wasvery stress free,” said Pushka.Today, the Esterhazy mine sites have20 concurrent licenses of Adept. Thereare 14 drafts people who use Adept fordesign-intensive work with CAD applicationssuch as Mechanical Desktop andInventor, as well as a 100 people whouse Adept’s built in viewer to view andmark up drawings and collaborate. Adeptis also used in operations and maintenanceby electricians and instrumentationpeople who need to easily access the latestversion of a drawing for ongoing maintenance.The plant surface and undergroundengineers use Adept to manageand control their drawings. Since Adept’sdesign provides a centralized repositorywith access to all information, it gives thepeople in purchasing, planning, and constructioninstant and controlled access tothe drawings for their work.Explained Pushka, “Adept has providedgreat cost savings because peoplecan access drawings quite efficiently attheir own workstation. They don’t haveto come back to us and waste our timesearching and printing out older drawings.”At the Esterhazy location, Adept managesmultiple types of files and all theirinter-relationships, including AutoCADMechanical Desktop, Autodesk Inventor,Microsoft Office, JPEGs and scannedlegacy drawings. Now, 95% of its engineeringdesign drawings – that’s 62,000electrical drawings, instrumentationdrawings, mechanical drawings, generalarrangement drawings and shop details –have been scanned into Adept.“Basically Adept manages for us everydrawing needed to build a plant site. Wecan track every wire, every piece of graveland concrete, locations, radioactive sources,you name it,” explained Pushka.This article was contributed by SynergisSoftware, a division of SynergisTechnologies, Inc.www.synergis.comLP-108 outlines.ai 2/11/2008 2:01:55 PMWainbee_DPN_Nov08.indd 110/27/08 9:08:07 AMUntitled-2 12/15/08 10:02:35 AM
26 Design Product Newsdpncanada.com November/December 2008Feature: Enterprise CADProduct Lifecycle ManagementRoad Map 2008 conferenceDETROIT – The Fall 2008 and 15thPLM Road Map conference presentedby Collaborative Product DevelopmentAssociates (cpd-associates.com) addressedthe issues arising in reconciling more andmore detail across more and more expertdomains from design, through simulation,on into manufacturing, and extendingacross the supply chain. Successfullyaddressing the full needs of product lifecyclemanagement (PLM) across the fullproduct lifecycle clearly involves the transformationof the business – presentingdeep cultural challenges involving processmanagement and standardization.In the conference track covering detailedtechnology issues, integration acrossthe electrical, software and mechanicaldomains represented a major theme. WooJin Ho and Jay Vleeschhouwer of MerrillLynch concisely summarized two trackswith the conclusion that PLM/PDM adoptionis “coming of age,” and that the“transition to enterprise simulation managementis still early, but becoming morepromising,” according to “The SoftwareStandard” report published by MerrillLynch last month.Christian Verstraete, CTO forManufacturing and Distribution Industriesat Hewlett Packard, kicked off the conference.He focused on the processes, thepeople, and the technology required tooptimize the use of an extended supplychain, with particular concern for collaborativerelationships with key partnersin developing and optimizingcollaborative processes.While automotive, aerospace,and manufacturingfirms have faced sharplyaccelerating rates of changeand challenge, the semiconductor and ITcompanies have lived with acceleratedrates of change for over half a century.With 13 years of corporate leadershipat Toyota’s Georgetown, Kentucky plant,Michael Hoseus (above) reviewed howthe Toyota culture builds on the respectfor people and their development to fullysupport efforts with continuous improvement.A process orientation depends uponmanagers who understand that the rightprocess will get the right results.

A commondeficiency with most PLM systems todayrelates to a major time lag in the feedbackon costs and profitability to engineering.All too often, by the time the financialside of the business runs its numbers, theengineering team has moved on and theopportunity to redesign for greater profitabilityhas been lost. Early and efficientverification of costs and profitability helpsto avoid this scenario.A panel discussion on standards forPDM interoperability hosted Ric Wagnerfrom Ford, Paul Downing of Prostep andRahul Garg of Siemens PLM Software.The success and payoff of an integrationplatform based on standards allowsorganizations to select best-in-class productstailored for their organizations in aheterogeneous environment. A structuredand standardized approach helps companiesto realize their enterprise integrationneeds and directly contributes to thesuccessful implementation of integration,synchronization and migration strategies.The supplier should be able to automaticallysynchronize not only geometry butalso metadata, product structure, positioningand configuration data. Of particularnote, Ford and its suppliers today are ableto share “complete” product informationvia JT irrespective of the originatingnative CAD data format, while supportingfull design in context processes.In his closing keynote on Future Trendsin PLM, Terry Kline from General Motorshighlighted that the Global ProductDevelopment at GM now operates as oneglobal organization, rather than regionaldevelopment centres.Information systems and services haveplayed a critical role in the ongoing transformation,and in driving the full optimizationof virtual product developmenton a global basis. It must deliver a globalarchitecture for PDM and collaboration,fully addressing the range of challengesinvolved with the people, the processes,and the technology to drive faster speedto market.Next issue: PLM Road Map 2008Conference, Part 2: reports on theDesign Creation & Validation, Design/Simulation, and Mechatronics ProductValue Management tracks.Designfusion_DPN.indd 110/22/08 3:16:35 PM

That’s the easy choicemade every day by residential, commercial,and municipal customers of TrojanTechnologies, whose systems disinfectdrinking water with ultraviolet light.More than 60 designers and engineersat Trojan (trojanuv.com) design and configuresystems for some of the world’smost important water sources, whetherin single-family homes or world-class cities.Trojan systems also treat municipalwastewater environmental contaminantsand micropollutants.Based in London, ON, Trojan is thedesigner and builder of the largest UV disinfectionsystem in the world, made up ofSwitch from needle bearings to GGB bearings and design smarter.Smarter designs result when you switch from needle bearings to GGB bearings. That’s because ourbearings are lighter, have as little as 2 /3 the profile of needle bearings and there are no needles, so66% heavier NumerousNo moving parts less can go wrong. GGB bearings also have a greatermoving parts Low weightcontact area for higher load capacities and they perform wellin oscillation conditions as compared to needle roller bearings.In addition, many GGB bearings require no lubrication andthe one-piece design is very cost-effective. So, for smarterdesigns, use lighter and stronger GGB bearings.Strict lubricationrequirementsNo lubrication56 water disinfection units for the NewYork City Department of EnvironmentalProtection. The facility is capable oftreating up to 2.2 billion gallons of watereach day. In addition to having createdthe largest disinfection system, Trojanalso has the largest installed base of UVsystems on the planet, with more than5300 municipal facilities in more than 78countries using its technology.In a Trojan system, UV rays penetratebacteria and viruses, destroying their abilityto function and reproduce. The processis simple but effective, crippling harmfulmicroorganisms without adding chemicalsor changing the water’s taste or odor.“We’re not adding anything to thewater, we’re just shining light throughNeedles are2x the staticload capacityfor cacti,porcupinesand knitting.But, when it comesto bearings,you’re better off with GGB.To find out more, visit www.GGBearings.com/needle or callyour GGB sales representative.GGB North America • 700 Mid Atlantic Parkway, Thorofare, NJ 08086 Tel.: 856-848-3200 • Fax: 856-848-4552 • usa@GGBearings.com©2007 GGB.

Thecompany uses SolidWorks Enterprise PDM to manageover 30,000 files.Technologies (javelin-tech.com), hassteadily shortened the company’s designcycle, lowered expenses and improvedquality. “We no longer have to leaveextensive room for error and build projectsa little larger than they need to be,”said Cerny. “We’ve also dramaticallyreduced the number of prototypes weneed to build – prototypes that canexceed $50,000 for municipal systems –as well as the errors that can crop up inprojects designed in 2D.”Today Trojan builds only one-third ofthe costly prototypes it once did. Cernycredits the effectiveness of its simulationsoftware and the accuracy of 3D CADfor the improvement.Productivity, of course, is a doubleedgedsword: A typical Trojan productmight have 500 parts. With 60 engineersand 10 years of legacy data, that meansa lot of parts, revisions, and versions tomanage and potential errors to avoid.Cerny figures Trojan is managing about30,000 files and counting.This management challenge iswhy Trojan has recently begun usingSolidWorks Enterprise PDM software,which is fully integrated with SolidWorksand its Flow Simulation software. Trojanbecame interested in the product datamanagement (PDM) product when itwas seeking to improve its ability tosecure, share, manage and reuse its voluminousproduct data. Cerny’s team sawthe benefits of Enterprise PDM’s abilityto span multiple geographic sites, automateworkflow, and leverage the familiarMicrosoft Windows Explorer interface,which along with the SolidWorksintegration, virtually eliminated trainingtime.Enterprise PDM has delivered thesecapabilities and has also enabled Trojanto collaborate closely with an engineeringteam it retains in Bangalore, India,Tata Consultancy Services Ltd. Tata ischarged with modifying Trojan productdesigns for specific customer sites. Trojansends the requirements to India, and theTata designers (using SolidWorks), do allthe production work, returning finisheddesigns before their North Americancounterparts at Trojan start their nextday. By the end of 2008, Trojan plansto add its new office in Shanghai, anexisting one in California, and a secondoffice in Ontario to the global enterprisedesign collaboration network.“Trojan never sleeps so that ourcustomers never need to wait,” addedCerny.This article was contributed by DassaultSystèmes SolidWorks Corp.www.solidwork.comGGB_DPN_Sept07.indd 18/21/07 9:37:37 AM

As usualwith any new release of a major product,the “What’s New” list in DS SolidWorks2009 runs to several hundred items butthe headline-grabbers definitely fall in the“user interface” category.Probably the most significant improvementthat DS SolidWorks Corp. has madein SolidWorks 2009 (solidworks.com) isthe fact that it has corrected a major blunderthat was made in SolidWorks 2008. InSolidWork’s defense, it sounded like a goodidea at the time. Microsoft switched all ofthe Office 2007 applications over to the newcommand ribbon interface, so it would seemto make sense to follow them to help maintaininterface consistency between many differentproducts from many companies.The only problem was that the Officedpncanada.comCAD Industry WatchRibbon re-think in SolidWorks 2009SpeedPakaccelerates largerassembly designand developmentribbon is a disaster, particularly in the factthat its position is locked at the top of thescreen. Hello, Microsoft; monitors are gettingwider, not taller! I personally disliked itso much that after a few weeks I reverted toOffice 2003 and added the free file compatibilitymodule from microsoft.com.DS SolidWorks 2009 corrects thisin a big way. It is now possible toundock the CommandManager and thePropertiesManager and to park them anywhereyou want. By “anywhere”, I mean“ANYWHERE”. They can be dockedat any of the four sides of the screen, orthey can float anywhere on your monitoreven if that happens to be outside theSolidWorks application window (aboveright), or even on another monitor if youare running a multi-monitor setup. Theforegoing also applies to the traditionaltoolbars if you have turned them on.Another cool interface feature is thenew magnifying glass, technology transferredthe Dassault Systèmes 3dvia productdivision. With it you can zoom andpan to a small region of your model andyet still see the rest of the model in context,exactly as if you were studying it with amagnifying glass.Not all of the interface changes andadditions in SolidWorks 2009 are visual.Another example of their efforts toimprove user productivity is shown by achange to something as simple as improvingcommand response consistency. InSolidWorks 2009, if any dialog box,PropertyManager, error message, or commandhas both an OK and a Canceloption, then pressing Enter will accept andpressing Esc will cancel the operation. Ifthere is only a Cancel option then pressingeither Enter or Esc will cancel.A change that you can pretty muchcount on in the next release of just aboutany parametric modeller is a new orimproved method for handling very largeassemblies. DS SolidWorks complies.Normally, when we say “large assembly”we usually think of numbers of components.In SolidWorks 2009, however,“large assembly” also includes assembliesthat are more than a kilometre across.Another aid to handling large assembliesin DS SolidWorks 2009 is the newSpeedPak functionality. If you want toinsert a complex assembly, such as agearmotor unit, into a larger assemblythen you create a SpeedPak of it first. ASpeedPak is a representation of the subassemblythat just contains a subset ofsome of the parts and faces in it, or perhapseven none of them.A SpeedPak file only holds graphicalinformation for the suppressed parts andfeatures, and so is much smaller. Even so,SpeedPaks do not lose restraint referencesas you would if you simply suppressedsome components.Better yet, the suppressed items in aSpeedpak are not available to downstreamusers.

If you suppress everything thenyou can send a SpeedPak of a sub-assemblyto a customer or supplier as a single file,without any of the referenced files.Finally, it is now possible to definea sketch element by using an equationin the form of y=f(x), such asax2+bx+c.

What we don’t see are thestrategically placed cameras thathave detected the fall. The detectiontriggers a speaker that audiblyrequests a binary answer (yes/no)– ‘are you O.K.?’ ‘do you need me tocall an ambulance?’The voice could then ask: ‘would youlike us to call your daughter’ – yes/no –‘how about Jim your neighbor?’ Thisone gets ‘yes’ so the machine acknowledgesby telling the floor-bound personthat the call will be made and an updatewill be given momentarily.The lab is not limited to fallingscenarios – there is a robotic exerciserthat helps stroke patients to strengthentheir upper body muscles, andsystems that provide oral and visualclues to guide people with dementiathrough routine functions such aswashing their hands. There is also ananti-collision wheelchair for peoplewith reduced operational skills.All of the systems are designedU of T Lab has developed an anti-collision wheelchair(left) and a hand washing station that integrates foursystems. Inset: Dr. Alex Mihailidis. Reprinted withpermission from the Dept. of Occupational Science andOccupational Therapy, University of Toronto.to help older adults with cognitiveimpairments to maintain independencein their homes.In creating these devices, Dr.Mihailidis and his team of graduatestudents draw from the fields of robotics,mechanical engineering, artificialintelligence, gerontology, voice recognitionand computer programming.What makes the designs unique isthat they are intelligent and can, withthe help of custom computer algorithms,learn and adapt to needs.The value in all of this work is notso much in the brilliance of the technologybut in the potential for independencethat it affords the users.“We don’t want to develop any technologythat the patient or caregiverhas to sit down and learn how to use.That just adds to the burden. Thegoal of our systems is that you turn iton and it starts working immediately,learning about, and adapting to, eachperson,” said Dr. Mihailidis.When dementia impairs a person’sability to perform routine activitiesthey often can’t remember the propersequence of steps to take or how to usenecessary daily tools such as cutlery.Although there’s no substitute forthe warm body in the process of caregiving,there is a technical responsethat can greatly reduce the pressure onthe caregiver and provide the patientwith a degree of independence. Anexample is The COACH (CognitiveOrthosis for Assisting aCtivitiesin the Home). This was originallydeveloped to assist in theprocess of hand washing, butthe basic technology can be usedin a variety of applications.The system employed four integratedsystems: a tracking, statemonitoring, Markov decision process(a mathematical frameworkfor modeling decision-making insituations where outcomes arepartly random and partly underthe control of the decision maker)and prompting modules.The tracking componentidentified the position of theuser’s hands and towel by applyingbackground subtraction andcolor matching on images acquiredthrough a video camera mountedover the sink. This technique couldisolate the skin-toned objects (i.e. theperson’s hands) and then determinethe two-dimensional coordinates ofthe hands. The system then, with aseries of audible prompts could guidethe user through the entire processsaying, for example ‘John, put thesoap down,’ ‘Now turn off the tap.’The system was designed to providethe lowest level of detail required forthe user to complete the process andthereby encourage cognitive involvementand maximum independencefrom the caregiver.Mark Sunderland is President,BioMedical Industry Group, Ottawa(email@example.com).aster_DPN_Nov.indd 110/27/08 10:46:01 AMHolding your world togetherAvdel ® Blind Fastening SystemsM.W.

38 Design Product Newsdpncanada.com November/December 2008Advisory Board DirectionsWorking together for the common good:Canada’s answer to global competitionBy Millan YeungThere is no secret that the manufacturingindustry in North Americais going through tough times atthe moment. Many jobs have been lostand plants closed. Competition abroad, thehigh cost of fuels and materials, and theworldwide slow down in the automotiveindustry has contributed to the tumble ofthe manufacturing industry.While Canada’s economic outlook is stillstrong, we need to keep up our productivityand innovation to maintain stability andgrowth. Traditionally, small and mediumsized enterprises (SMEs) represent a largeportion of Canadian manufacturing industry.SMEs are flexible and can react tochange rapidly. This provides great adaptabilityto customers’ needs and wants inthe world market. Many suppliers, developersand even some OEMs control theirgrowth so that the size of the company isalways manageable, flexible, efficient andless bureaucratic.A typical SME possesses only limitedcapability and resources, and lack of capacityto tackle large contracts or projects thatwould significantly increase revenues, createnew jobs and provide long term growth tothe company. To overcome this disability,leaders of industries and communities haveinitiated a new strategy and approach thatallows SMEs to take on large projects. Thegoal is to bring relevant SMEs together intoa group or groups to solve problems andtake on challenges through networking,knowledge sharing and joint marketing andpromotion.Cooperationpermits SMEs to takeon larger projectsThe 2008 Americas HyperWorks Technology Conferencewill bring together more than 400 global engineeringprofessionals, from a broad range of industries,to discuss trends and advancements in simulationthat are driving product innovation.Call for Presentations — www.altairhtc.com/c4pSponsorship Opportunities — www.altairhtc.com/sponsorMore Information — www.altairhtc.comAltair HyperWorks is a division ofINTRODUCINGAltair ® HyperWorks ® 9.0Pay-for-use CAE software licensingBroadest ISV partner eco-systemUnequaled modeling, visualization and reportingNext-generation solvers for linear, nonlinearand multi-body dynamics applicationsRecognized optimization technology leaderComputing environment virtualization toolsAutomated performance data managementFor more information visit:www.altairhyperworks.com/HW90Built on a foundation of design optimization, performance datamanagement and process automation, HyperWorks empowersinnovation and rapid decision-making to get to the ‘right’ answer faster.Built on this concept, several communityor regional based organizations havebeen formed in south-western Ontario.Communitech (communitech.ca) inWaterloo, ON, was established in 1997 andhas become one of the successful models ofthis concept.
