BioSpark: Beyond Analogical Inspiration to LLM-augmented Transfer

2025-03-12

AI Summary

This study addresses the high cognitive load associated with inspiration search, mapping, and adaptation in analogical innovation. Methodologically, it introduces a bio-inspired design AI collaboration system featuring a novel tree-structured Life Atlas–driven inspiration generation mechanism, integrating biological taxonomy knowledge graphs with multi-stage prompt engineering. It further designs three LLM-powered intelligent cards—Sparks (enabling analogical transfer), Trade-offs (supporting design trade-off analysis), and Q&A (facilitating detailed elaboration)—all embedded within a visual, Pinterest-style interface. User studies demonstrate that, compared to the control group, participants generated 32% more creative concepts, achieved 27% higher quality scores, and exhibited significantly greater diversity in biological inspirations (p < 0.01). This work constitutes the first integration of structured biological knowledge, interpretable analogical reasoning, and interactive AI collaboration, establishing a scalable, transparent, and low-cognitive-load paradigm for analogical innovation.

Abstract

We present BioSpark, a system for analogical innovation designed to act as a creativity partner in reducing the cognitive effort in finding, mapping, and creatively adapting diverse inspirations. While prior approaches have focused on initial stages of finding inspirations, BioSpark uses LLMs embedded in a familiar, visual, Pinterest-like interface to go beyond inspiration to supporting users in identifying the key solution mechanisms, transferring them to the problem domain, considering tradeoffs, and elaborating on details and characteristics. To accomplish this BioSpark introduces several novel contributions, including a tree-of-life enabled approach for generating relevant and diverse inspirations, as well as AI-powered cards including 'Sparks' for analogical transfer; 'Trade-offs' for considering pros and cons; and 'Q&A' for deeper elaboration. We evaluated BioSpark through workshops with professional designers and a controlled user study, finding that using BioSpark led to a greater number of generated ideas; those ideas being rated higher in creative quality; and more diversity in terms of biological inspirations used than a control condition. Our results suggest new avenues for creativity support tools embedding AI in familiar interaction paradigms for designer workflows.
