Enventive CAD models are perfect. The real world is NOT.

• Huge savings in tooling rework, design iterations, scrap, customer loyalty.

• Proven corporate application in fortune 500 industrial companies.

• Unique technology and fastest growing MCAD company.• Management Buy-out 2001, Boston USA• First re-developed product delivery: 2005• Average growth over last 8 years: 40%• We have been busy !

“Enventive has enabled our mechanism design engineers to literally start thinking again in order to make the right decisions on their preliminary designs problems. This allows us to avoid various types of costly late stage problems in our design and industrialization processes”Norbert Hertling, Engineering Director – Lear Corporation Gmbh

Cost/Benefits

Company Background

Sample clients using Enventive

Sample 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.

Typical process for optimizing of design for robustness

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.

What is preliminary tolerance analysis based design optimisation ?

• Better satisfaction and confidence from customers, due to the fact that robust design methods can be the basis for taking decisions in preliminary design.

• Savings in terms of tooling changes, design iterations and scrap.1 avoided tooling change in one programme allows to save in general at least £30k and much more than £75k in most of the cases.

• Better capacity to innovate, with same human resources and R&D investments Because the R&D teams are able to design more easily and more quickly products that are more sophisticated.

• Better capacity to manage changes during the lifecycle of the product. (Better management of crossed impacts on several conflicting functional requirements).

• Better capacity to react when facing drifts of production outputs. (Leveraging sensitivity information to know where and how much to act.)

• Exhaustively when enlarging tolerances of small impacts contributors.Savings that can be made by asking larger tolerances to subcontractors on small impact contributors can be valued to several thousands of £’s and often several tens of thousands of £’s.

• Reduction of prototyping costs. (Enventive acts like a variational mock up).Depending on the industry, avoiding one prototype allows to save several thousand of £’s and in high tech industries (aerospace, medical instruments…), this can go up to several tens of thousands of £’s. Clients often go from 5 to 1 to 0 Prototypes.

Is Enventive easy to use ?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 – Technical Director – Ficosa InternationalEnventive Training:

Two First Days: Functional training

The training is not simply about how to use the softwareAdditional topics covered:

• The principles of root sum squares calculations for complex tolerance stacks calculation.

• The principles of sensitivities calculations and its use in Enventive for the preliminary design definition of components and assemblies.

• Inherent variations in production due to different manufacturing processes

• Forces and frictions modelling and their statistical analysis.• Combining in Enventive variations due to physical effects such as

temperature and wear.

Thank you for your attention
