Abstract

This research focuses on developing a psychology-based evaluation procedure for innovative design. The divergent thinking part of the main innovative design procedure which discussed in this paper is the extensive QFD developed by the author (Wu). The major performance of QFD is to identify the customers’ requirements and their priorities. Then, the proposed extensive QFD helps transform the high priority requirements into appropriate technical characteristics. According to the priorities of product characteristics, the prior engineering parameters will be identified to be the key performances to redesign. For identifying the requirements and achieving the attractive design, we introduce the Kano model to construct the evaluation model. The proposed Kano-based evaluation procedure is mainly used in two stages of the innovative design. First, the evaluation process was used in QFD stage to help identify attractive customers’ requirements, and the other was used in the extension stage to help assess concepts. The flowchart of proposed innovative design procedure with psychology-based evaluation has also been developed. A case study, exercise equipment design, is adopted to explain and verify feasibility of the proposed approach.
