| Summary: | 碩士 === 國立成功大學 === 工程科學系 === 104 === Creativity is an important abilities of industrial designers, can help designing and realizing innovative products. Today industrial design usually requires group collaboration. How to effectively stimulate group creativity is an important issue on pushing product innovation. In the field of design, sketches and words are typical ways of conceiving ideas. A Picture has a lot of encoded messages that can stimulate ideas in the phase of creative thinking, while words can integrate features that can facilitate interpretations of the concepts in a picture and point to the right directions for thinking. The 635 brainstorming method and C-Sketch method are team-based divergent thinking techniques. The former uses words while the latter uses pictures as a way to stimulate group creativity. This study fuses the 635 brainstorming method and the C-Sketch method to help group designers, by alternatively using pictures and words in the divergent thinking phase, stimulating and integrating their ideas from different aspects for developing innovative products. To evaluate the feasibility of this hybrid technique, this study conducts two experiments. In the phase of the divergent creative thinking, the experimental group uses the proposed method in all the occasions, while in the first experiment the control group uses the 635 brainstorming method and in the second experiment the control group uses the C-Sketch method. After the creative thinking, all the groups must discuss and finalize a product through group collaboration. The results show in the first experiment, using the proposed method, the originality and elaboration of the group creativity are significantly better than using the 635 brainstorming method, but the fluency and flexibility are not. In the second experiment, using the proposed method, the originality and elaboration of the group creativity are significantly better than using the C-Sketch method, but the flexibility is not. However, the C-Sketch method performs significantly better than the proposed method in the fluency of group creativity. The proposed method also performs better in creating final product. In addition, the results show no significant correlation between the personal divergent thinking ability and the group-based product design capability.
