A Product Design Approach by Integrating Axiomatic Design and TRIZ

The purpose of this research intends to integrate the strengths of axiomatic design (AD) theory and theory of inventive problem solving (TRIZ). This study establishes a systematic product design model by adopting some major tools from AD and TRIZ such as functional requirements, design parameters, design matrix, contradiction matrix and inventive principles. Furthermore, the proposed model's efficiency is analyzed and evaluated by a case study of a Handheld GPS product. Results indicate that the design model which combines with two theories can find out the usability problems and solutions efficiently. When applying the proposed model on product redesign or new product development may avoid the cost waste and increase the design efficiency and usability during the product design and development processes.
