Abstract: Researches on product design were analyzed from different perspectives. The purpose and significance of conducting creative design studies based on cognitive experiment were presented as well. Through constructing and describing the process model of idea generation for creative design, the feasibility of applying cognitive experiment into creative design research was discussed. According to the characteristics of creative design, a creative design research method using Protocol Analysis (PA) was proposed. In this method, thinking aloud was utilized to obtain creative design information; after processing and analyzing those information, some conclusions and rules of creative design could be obtained, which laid foundation for the establishment of design theories, methods and tools. Finally, an experiment was presented to illustrate the proposed method.

Key words: product design, creative design, cognitive experiment, protocol analysis
