碩士 === 國立高雄應用科技大學 === 模具系碩士在職專班 === 102 === How to quickly and effectively develop new products and take the transition to mass production under the pressure of time to market and production costs is the objective for many companies. However, a new product development always need numerous human resource and material resource, many companies would like to get the order first, then accumulate the successful experience by correctting and improving the failure. This will cause not only loss of customer confidence but also great failure cost. But we can reduce the failure and cost, speed up the time to market by implementing a new product with a systematic process. In this research, Design for Six Sigma (DFSS) is adopted to help a switch manufacturer that meet the high thermal request form the customer and need to speed up the time to market. In this study, all steps of DFSS, i.e., DMADV (Define, Measure, Analyze, Design, Verify), are used to help the manufacturer to design a special switch which can be used in high thermal environment. In the Define phase, the maintained mechanical pushbutton switch is descripted and the why the request form the customer is defined. The root cause of the request is identified by brainstorming in the Measure pahse. Then the usable inventive principles are computed by TRIZ matrix in Analyze phase. Using the inventive principles to compute the optimal design parameters in the Design phase which done the experiments by Taguchi Methods. Finally, the result of life test is established and trial run is also succeedful in the Verify phase. After running all the steps of DMADV, the finally design not only meet the request from the customer but also improve the standard switches form the manufacturer.
