How Kikusui helped company P gain test environment with high precision variable DC power supplies in their limited installation space.

Company P manufactures and sells automotive airbags. The airbag is a vehicle safety device to protect human’s life. Under some rare conditions, the airbag can cause fatal accidents. The airbag module is designed with high accuracy so that the airbag system shall be activated to minimize the effect of accidents once they occur.

The Problem

Company P’s verified product could not get approval at the business partner’s evaluation, that led Company P to face a crisis of losing the business.

When company P submitted a newly developed prototype to the business partner for evaluation, it was returned with the comment that its performance was insufficient. The problem was with testing equipment that could not deliver accurate test results.

Mr. R in design and development on the project recalls that a vast number of requirement errors still slipped through the business partner’s evaluation process, although many defects were fixed. Comprehensive reviewing all its safety structures, processes and compliances are vital in preventing recall or car accidents caused by faulty devices.

Company P was in danger of losing the business against one of their competitors if it failed to improve the product quality to a level that would satisfy their business partner’s demands.

The company P was aware that this was due to poor performance of their variable power supplies. The company P wanted to establish a new test environment to perform the higher precision development and test in their limited installation space.

In addition to improving the test environment, Mr. R wanted to implement a system infrastructure to control and monitor the power supplies on the network.
Mr. R was at a loss without any ideas about specifically what to do.

Key Aspects of the Problem

  • The company P wanted to establish a new test environment to perform the higher precision development and test.

  • The constraints of installation space to implement a large test system.

  • The company P wanted to control and monitor the power supplies on the network.
