This situation of the recent growth of technology improvement, market competition toward products has caused a short product life cycle, forcing enterprises to produce new products and services to satisfy market demand in efforts to maintain competitive advantage. Traditional product research and development processes for new products lack integrated design improvement and evaluation tools. Therefore, how to develop a product design improvement model to meet customer demand and select the optimal product improvement/corrective solution is the study background and motivation for this research.
This paper integrates three major methods, including the FMEA (Failure Mode Effective Analysis), the TRIZ, and the AHP (Analysis Hierarchy Process) as a system to build an evaluation model in the product improvement phase of the product design and development stage. This research first uses the FMEA method to predict the possible quality problem and the potential risk on the customer side. Then, we investigate the Risk Priority Number (RPN) in each production process to find the necessary corrective action. After the definition of the top major failure item in design, we use the TRIZ as the reference tool for the product improvement analysis. Finally, an expert questionnaire sets the target and sums up each criterion for the design improvement to build a hierarchy relationship between decision criteria. The AHP method is used for criterion pair comparison to come up a better design concept.
This paper uses the automobile stamping product as an illustration to provide a relevant decision-making reference for R&D personnel, and sets up an integrated model of innovative product design improvement.
