Voice of Customer • Sometimes forgotten due to time Tolerance and pressure constraints. Analysis Product Problem • Results not interpreted and valued. Requirement Resolution Simply sent to customer for Specifications justification. • Complex problems Require Conceptual Production engineering change requests or Design Release tooling changes, meaning time and (Initial prototypes) (Hard Tooling) costs. • The probability to have problems in Detail Design Pilot Program production/assembly/usage is much (Further prototypes higher and testing) (Soft Tooling) Tolerance • Tolerance analysis is a bottleneck in Analysis Product Release the development & industrialisation to Manufacturing process.
- 6. Solution Desired by Customers Managers want pushbutton tolerance NO MATH STRUCTURE IN CAD SYSTEM analysis from CAD system Plane defined by X,Y,Z Coordinates of points. This solution does not currently exist CAD mathematical structure inadequate for tolerance analysis. Because of the CAD limitations, extremely difficult to develop a CAD-based Plane defined by X,Y,Z Coordinates of points. pushbutton solution. No mathematical relationships between the surfaces

Comments from Enventive Users… “We can conceptualize design concepts ten times faster in Enventive than we can with our native CAD system… Rather than seeking to simply avoid problems, by using tolerance-based optimization early in the product development process, well up-front of traditional CAD, we’re able to use Enventive to target and achieve optimized design solutions and aggressively establish competitive product offerings.” Yves Le Pottier – Electrical Device Supplier “I cannot leave a discussion of Enventive without mentioning it is fun to use. The software is graphically based. Sketches and graphical representations of the parts drive the models. This, coupled with the easy to use interface, creates “Stack-up Junkies” who want to do the analysis because the software helps them easily visualize the impact a design change can have on the product.” Eric Pattok – Delphi Steering Systems “Our engineering team has been able to use Enventive after 4 days of training. We have been able to correct some design mistakes that were done in the past due to the limitations of the tools we were using. In the end, our customer praised us for the speed and professionalism with which we have been able to complete and present the DFSS phase on this project.” Pedro Lopes – Ficosa International
