CONSIDERATION OF ROLE OF SKETCHING BASED ON THE MULTISPACE DESIGN MODEL

Abstract

In product design, sketching while designing serves various roles, but the effects of individual sketching skills, such as perspective expression, structure, and shape development, have yet to be clarified. Herein a structural model of sketching skills is proposed to unify and classify sketching skills, and the role of sketching in the thinking process of design is analyzed using the Multispace Design Model as a comprehensive viewpoint based on the effects of various sketching skills previously elucidated. The results show that in the thinking process of design, sketching is used to generate ideas for the optimum design by a top-down process, which optimizes the results in physical space using the analysis results in psychological space. Additionally, sketching is used to evaluate ideas for the emergent design by a bottom-up process, which extract new meanings in psychological space based on attribute development in physical space.
