Abstract

Abstract:

Based on theoretical studies in design-driven innovation and disruptive innovation, a design-driven disruptive innovation model was proposed, thereby enhancing research on disruptive innovation methods in design. This model comprised three stages: meaning discovery, functional system adjustment, and product language expression. Firstly, based on SET, market trends were envisioned for new product meanings, and internal critiques were utilized to explore feasible product meanings. Then, research on target users utilized AD to map functional requirements into design parameters, which were compared with the original product technology to adjust and achieve disruptive innovation solutions. The new product meaning features and the parts corresponding to the improved and added technologies were identified for product meaning interpretation, and samples of these parts were selected using analogy reasoning. Finally, similarity analysis was conducted to determine the design prototype and extract its elements. Extenics was employed to optimize the product language expression, resulting in a disruptive innovation product language solution. The electric wheelchair design example validated the model’s feasibility, providing a reference for other design-driven disruptive innovations.

Key words: design-driven innovation, disruptive innovation, product language, product meaning, functional adaptation, electric wheelchair
