Window Closing Effort

Challenge:

A high volume automobile had a problem with window closing effort. While the ideal value is 12.5 in-lbs, both right and left side windows were averaging around 20.0 in-lbs, which caused multi-million dollar warranty costs.

ASI Solution:

ASI Consulting Group optimized tolerances of components around the door assembly and window regulator.

Achieved Benefit:

The team finished tolerance design in two weeks. As a result, tolerance of two components was adjusted and window efforts were reduced to approximately 13 in-lbs. There was a multi-million dollar reduction in warranty costs.
