New Interactive-Generative Design System: Hybrid of Shape Grammar and Evolutionary Design - An Application of Jewelry Design

Abstract

This paper proposes a new methodology for developing a computer-based design system. It places designers at the centre of design process to perform their tasks collaboratively with the design system. The proposed system is developed based on interactive shape grammar and evolutionary design algorithm, which is able to increase the creativity and productivity of design activity. Designers can utilize the generated designs to initialize their conceptual design process more easily and rapidly. The source of form diversity is derived from genetic operators. Subjective user preference is used for design evaluation. The system can be integrated with computer-controlled model-making machines to automatically build physical artifacts. As a result, designers can easily start their conceptual design process through obtaining the desired designs and the resulting physical artifacts in line. The human-computer synergy is illustrated for the design of jewelry, but it is applicable to other industrial product design problems.
