Thermal control: re-design to cost
of a thermostat nozzle

Our client, leader in the thermal control of fluids, designs and manufactures thermostats for the automotive and sanitation sectors.

Dual stakes for those in the fluid thermal control sector

Faced with the appearance of new competition from abroad which could reduce market share in the heavy truck sector, our client has to find solutions to:

  • Reduce development costs and unit costs. 
  • Improve and guarantee the overall performance of its product.

Reconcile economic and technical performance

Our client wants to: 

  • Retrocede gains in productivity.
  • Get rid of problems with cracking and associated sorting to improve the quality of this element.
  • Find a robust solution that is right first time to successfully pass a test cycle of 1 million km over 3 years. 

DECOREC must meet the followiing objectives: 

  • Redesign the part.
  • Reduce cost by 30%. 
Our diagnostic
After technical analysis of the part in its environment our design office holds a brainstorming session. Our client retains 1 option out of the 4 possible, which is tested and validated.

A co-development project

  • A partnership agreement is drawn up with a non-disclosure clause and a commitment to award the market.
  • Project managment within the deadline: 
    • 1 month design.
    • 1 inhouse brainstorming session with design and planning departments.
    • Prototypes made followed by initial samples.
