Study on an Innovation Design Model based on Creative Design Methods and DFSS

In order to solve the problems of product innovation design, an innovation model is developed. the five layers innovation design model integrates the creative methods (cluster analysis, brainstorm, TRIZ, QFD and reliable testing) and the process management method (design for the six sigma). The model take the step as following: taking advantage of the S curve of TRIZ evolution theory and design study to indentify the lifecycle stage, using the cluster analysis to study the customers' requirements, using brainstorm to define the most important requirement and the possible solution, utilizing the TRIZ to further explore the creative solutions, utilizing reliable testing to verify the reliable of the final solutions. The five layers model is proved highly effective by the case of lighting design.
