In this study, we attempt to capture the nature of the concept generation process by finding an effective thinking pattern for creativity. We consider a space composed of chain processes of concepts that are both explicitly evoked in the concept generation process and inexplicitly imaged as a thinking space, and we focus on two viewpoints - structure and latent sensitivities. The former refers to the structure of the thinking space; the latter, the latent concepts that are inexplicitly imaged in the thinking space. From these viewpoints, we propose a method for modeling a virtual thinking space using a semantic network, and we quantitatively analyze its pattern. As results, we found that there is a significant correlation between the structure and the creativity and that the model could clarify the nature of design creativity in the concept generation process. These findings suggest that factors that affect the evaluated creativity score for design idea are closely related to the structure of the thinking space. This indicates that there might exist an effective thinking pattern for creativity; thus, this model could be used for enhancing design creativity.
