Modeling a hybrid-compact design matrix for new product innovation

- This paper studies the problem analysis and idea generation for product innovation.
- A hybrid design method is presented based on Axiomatic Design and TRIZ.
- A compact matrix is developed for practical applications.
- The proposed method is verified by a case study of an innovative ERE.

Conceptual design is a critical activity during the early phases of new product development (NPD) because most creative ideas will be generated in this process. Without creativity in design there is no potential for innovation. A complete design process for product innovation must include problem analysis and idea generation simultaneously. However, both Axiomatic Design (AD) and Theory of Solving Inventive Problems (TRIZ) techniques have their own advantages and drawbacks. There is the attribute of complementarity between AD and TRIZ in practical application. Based on AD and TRIZ, this paper presents a novel hybrid-compact design matrix by integrating problem analysis and idea generation approaches into the conceptual design stage for new product innovation. Despite the recognized importance of innovative design, there is a lack of systematic and effective design process that can cover all conceptual design activities. To address this gap, a useful and powerful hybrid model of the problem-solving is created for innovative product design, depending on the capability of AD detailed problem analysis and the expertise of TRIZ innovative idea generation. Finally, a case study of designing a new elderly rehabilitation equipment (ERE) is used to demonstrate the proposed method and the results verify the feasibility and effectiveness of the approach. This hybrid-compact design matrix can really help designers generate more creative outcomes in NPD.
