Enventive is an innovative tool that allows the engineers to base their early design decisions on the definition of the Quality function of the products that they design. It is used preferably in the conceptual stage, before any CAD data has been generated and can be the first stage in Design for Six Sigma (DfSS).

2. • 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

3. Sample clients using Enventive

4. Sample clients using Enventive

5. •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

6. 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 ?

8. Enventive – Evaluating return on investment:
Statistical analysis and optimisation of complex designs in early
stages of the design:
↘Design Iterations
↘Prototypes
↗Customer Confidence

9. Enventive – Evaluating return on investment:

11. Enventive – Evaluating return on investment:
Ability for engineers to « perturb » their designs and understand its
behavior early stage.
↘Probability of production & pre-series problem.
↘Probability of warranty returns.
↗Capability & knowledge of identical engineering resources.

12. • 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.”
