Study On Part Design Standardization And Cost Reduction For Automotive Lamps

For enlarging Global business and domestic marketing , Part design standardization was introduced and implemented in a automotive lamp company which request design and development department to improve design capability and design for cost.According with situation of auto lighting design department , author analyzed product feature, and got conclusion that what mostly impact on design efficiency and quality was low standardization grade of parts, there was no parts information library and effective parts information managing system.The thesis was suitable with group technology and part design standardization theory,the standardization method is decision-making by AHP ,and fit some company . Firstly, by categorizing similar parts to managing parts in production, recommendation were made when selecting standard part. Then, basing on recommendation parts and parts in category III, A company constructed Library of 3Dand 2D data and Library of samples of those parts, old parts information managing system was improved. At last, the thesis analyzed the improvement results of standardization from direct and indirect profit aspect.The thesis make forecast that after the implement of standardization, integrity rate of parts will reach 5 ~10 %, cost of purchased parts will decrease 30%, along with 30% lower design cost. This standardization activity in product design department must be a good start of continuously improvement in whole company, then in turn a good basis of whole-aspect standardization in company.
