Live Case Study
We identified the gap mainly through 2 systems in Haier Group and third party research reports.
As one of the top 3 highest loss modules, gear clutch modules cost huge losses, with quality loss rates up to 0.224%. User satisfaction with gear clutches is only 69.2. As the second-highest cost, after-sale maintenance costs are up to $6,750,000. The team aimed to create top level products, eliminate persistent quality defects through establishing reproducible quality organizations, and achieve the change from warranty to guarantee by establishing the most competitive quality assurance system. We adopted MSA,CPK,SPC,P-MAP, and C&E matrixes to select failure factors and got 11 key factors from the original 255 factors. We applied finite element simulation technology and designed experiments to analyze key characteristics of washing machine parts and obtained the best solution within the shortest time through the adoption of advanced analysis technology. Once the failure parts and their causes were found through simulation analysis, we redesigned those parts. Upon acquiring a satisfactory result from simulation test, we made a prototype and conducted small-scale tests, which showed significant effect.
