Abstract Bionic innovation design refers to the innovative design of products by extracting biological information in nature, which has great application prospects. The traditional bionic innovative design method mostly applies a small amount of biological information, which is difficult to efficiently retrieve a large amount of biological information, and it is difficult to produce innovative design solutions due to the limitations of designer’s thinking and related professional knowledge. To solve the above problems, it is necessary to propose an integrated innovative design method based on a large number of biological texts from website to assist designers in making bionic innovative design. Based on this, an innovative design method was proposed for mapping network biological texts by user requirements to obtain multi-disciplinary requirements and multi-mapping targets design scheme. Firstly, based on the neural network model, the knowledge in the internet biological text was extracted and stored in the database. Then, the keywords of product design were obtained according to the multi-disciplinary requirement mapping method, which was mapped to internet biological texts by using the fuzzy mapping method to obtain engineering design solutions. Finally, the code was programmed and the corresponding user interface was designed according to the above method, and the feasibility of proposed method was verified by taking the innovative design of the tubeular type air heater as an example. The results showed that the heating effect of optimized tubular type air heater was significantly improved, which indicated that the proposed method could solve the current key problems of traditional innovative bionic design, such as the lack of biological text information, the limitation of designer’s own thinking, the lack of integrate interdisciplinary expertise and the unsatisfactory generation of product solution. The proposed method can assist the designer to complete the bionic innovative design of products.
