Abstract

Development of fascinating products has always been aspired by product designers. Trade-offs are one important aspects to consider improving a product functionality. When significant trade-off is relieved by a sort of invention, functionality of a product reaches new frontier. This paper proposes a method to support ideation of inventive solution based on analysis of trade-offs and physical contradictions in a product, which are mapped to contradiction matrix of TRIZ. Validity of the proposed method was confirmed through a demonstration with Continuous Variable Transmission.

Keywords: idea generation, early design phase, innovation management, TRIZ, complexity
