A Bio-Inspired Design Method Based on LLM: A Case Study of Flying Car Concept Design

Bio-inspired design (BID), as an important method for product innovation, still has many challenges in knowledge retrieval efficiency, feature mapping and solution generation. We proposed a dialogical BID method based on large language model (LLM), aiming to enhance the efficiency and innovation of the design process through human-computer collaboration. Using the conceptual design of a flying car as a case study, we accomplished an innovative transformation from the biological features of a humpback whale to a product form through multiple rounds of dialog with LLM. Experimental evaluation showed that the method was outstanding in terms of novelty and fashion and symbolization. The study confirms the effectiveness of LLM in BID and provides new methodological ideas for product innovation.
