Innovative design of the seal structure of butterfly valve based on TRIZ

Abstract

Innovative ideas generation is a key step in the innovative design of the products. Computer-aided innovation (CAI) systems based on TRIZ (Theory of inventive problem solving) support new ideas generation of innovation. The patterns and lines of technology evolution in TRIZ provide a powerful structured methodology for a directed development of new products. The concept of 'evolutionary potential' and the method to construct an evolutionary potential plot are introduced. The Innovative ideas for new product development can be generated by the analysis of the evolutionary potential. A general process of the innovative ideas generation is then developed. A butterfly valve's seal structure case study is presented to demonstrate the process. © 2006 International Federation for Information Processing.
