Innovative Design Method of Product Service System by Using Case Study and TRIZ Method

Abstract

This paper presents a TRIZ based eco-innovative design methodology to support designers to develop product service systems (PSS). This method is based on TRIZ, which was developed in the former Soviet Union by Altshuller, who had analysis over 400,000 patents to build 40 inventive principles and contradiction matrix tool. In this paper, current PSS cases are collected and analyzed to identify consumers’ use habit in the PSS cases. Find out the relations between product and service in those cases. Analyzing product with its characteristics to get suggestions which for design new PSS. Then use the TRIZ 40 inventive rules to conclude innovative design rules for PSS. Product design may have more innovative possibilities by using these inventive rules. PSS innovation example was demonstrated to illustrate the effectiveness of proposed methods.
