A BERT-based model for coupled biological strategies in biomimetic design

The biomimetic design provides an adequate solution to attain an excellent design. However, the prototype space for biomimetic design is relatively large, and it becomes more and more challenging to find the required biological prototypes efficiently and accurately. To improve the design efficiency and enrich the biomimetic information, this paper proposes a coupled biological strategies-enabled bidirectional encoder representation from transformers (BERT) model to assist biomimetic design, namely BioDesign. We extract the biological strategies and extract dimensional information from AskNature as a part of the database. The linguistic expression model-BERT helps to search for biological strategy. Based on the coupled biological strategies analysis, the quantitative results of biomimetic strategies are given by BioDesign. Finally, we take the erosion wear-resistant design of the control valve core as an example to demonstrate the utilization based on the proposed BioDesign. The erosion wear experiment demonstrated the feasibility and effectiveness of the proposed method.
