Abstract

After products have been released to markets, from marketing competitions, not only functional improvements but also cost reductions are requested in improvement designs. But many of engineers are feeling difficulties to satisfy both of them at same time. We propose a process for improvement designs to satisfy these different kinds of features by using information integration method. Information Integration method is an evaluation way which is based on concept of Shannon's information theory. In this method, different kinds of features can be compared in a common measure called "Information". We apply this method to evaluate functions and costs in improving designs. We also propose an optimizing process for improvement design based on this method. By comparing evaluation items in this method, next target for improvement can be automatically selected without personal subjectivity. We have confirmed effectiveness of this process in a case study of electric shaver's improvement design. This study also makes up practical design processes with our previous studies "Practical Cost Reduction Methods based on TRIZ" and "Functional Improvement Methods based on Expert Engineers' Thinking Way".
