Abstract
In this study, to make clear the process of design thinking, a design experiment was done. In the experiment, during a given design task, experimentee's talkings and drawings were recorded to be analyzed. The analyzing methods are as follows. Firstly, according to the method of Yoshikawa's "Experimental Design Theory", the contents of experimentee's talking were sorted into 8 thinking units and then transition patterns between every thinking units were analyzed. From the result of this analysis, it can be said that the thinking process of industrial design is much more like Markovian model than the engineering design process. Secondly, from detailed trace of sequencial process of the drawings and experimentee's talkings, it can be said that there are some switch over stages at the end of every circular process of design thinking, and wording of conceptual form is seems to be a trigger of the switch over. As a result of this experiment, we can get a cue for making inductive model of design process.
