Car Exhaust Tail Pipe Product Design Research Base On Product Cost

Low price competition as one of the main competition strategy,the companies already focus on the product cost control.In regards of manufacturing industry,scholars have done lots of research that 80% of the product cost already been ascertained at the product design phase,there is only 20% space for product cost optimization in the latter production phase.Product design cost economics as one branch of technological economics become more and more important.Lots of companies and professors already done plentiful research on product design phase cost control.Summarize some new design solution like blocks design,design to cost,model design,value engineer etc.Automotive industry face severe situation: the prize competition among different brand vehicle company is very furious,so they require automotive suppliers also reduce the prize accordingly;Raw material expense and human expense also continuous increase;No big space for mass production phase cost save and leak of cost control in product design phase.All this indicate the necessity of the cost control research in design phase.TK is one of the companies,which produce exhaust pipe.Exist some disadvantage of cost control in its product design process: Without any cost target for the product design;designer finish the product design by himself,no team work;do not have good way to calculate all the possible design concept cost.Combine the disadvantage of exhaust pipe design process and face to cost design theory,optimize the exhaust pipe design process including organize design team with members from different department;define design cost target at beginning as the product design concept economy evaluation standard;set up math model to calculate all the possible part design concept and choose the lowest cost design concept.Design a exhaust pipe via new design process and cost calculation math model,the new design concept cost is much lower compare with the old one.
