Examples of clients using Enventive

Automotive = 75% of Enventive market

Examples of clients using Enventive

• Intensive time pressure to get a.s.a.p in production and on the market (solve costly Problems).

• Sometimes forgotten due to time and pressure constraints.

• Results not interpreted and valued. Simply sent to customer for justification.

• Complex problems Require engineering change requests or tooling changes, meaning time and costs.

• The probability to have problems in production/assembly/usage is much higher

• Tolerance analysis is a bottleneck in the development & industrialisation process.

Solution Desired by Customers

Managers want pushbutton tolerance analysis from CAD system

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 pushbutton solution.

Process change: pre-CAD Tolerance Analysis-Based Design Optimization.

• Process capabilities taken into account early in investigation.

• Diverse types of complex analyses: • Complex kinematics.• Complex ISO tolerancing.• Physical aspects (forces, contacts): need for

DOE and prototypes reduced.

• Structured Transfer Function optimization (focused on costs):

Number of contributors. Sensitivities. Tolerances Process Capabilities Tolerances on small impacts contributors.

• Design reliability justification from consultation phase. Customer Confidence.

• Ease of use and of deployment among engineers (no full time specialist required).

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.”
