融合RE与BID的产品创新方法研究及应用

针对已有产品的再创新、创新方法选用及创新方向的明确性等问题，提出一种融合逆向工程(Reverse engineering，RE)和生物启发设计(Bio-inspired design，BID)的产品创新过程模型。首先，通过RE对已有产品进行分析，经过结构分解、行为匹配及功能构建等步骤，建立其功能模型；其次，以该模型为基础，搜集产品用户需求，通过需求进化分析、需求重要度计算及功能进化，得到产品概念的功能再创新，进而组合出产品新功能待求解模型；最后，以生物系统逆向工程建模方法为基础，搜索并整理生物案例。利用所建立的生物启发设计辅助系统求解产品新功能，得到产品再创新方案。以方舱医院医护人员用防护服为例，验证了RE与BID融合的产品创新方法具有较好的可行性。

Research & Application of Product Innovation Method Incorporating RE and BID

Aiming at the re-innovation of existing products, the choice of innovative methods and the clarity of innovative direction, a process model of product innovation combining reverse engineering (RE) with biologically inspired design (BID) was proposed. First, existing products based on RE, their functional models were established through structural decomposition, behavior matching, and functional construction. Secondly, product user needs being collected through demand evolution analysis, importance calculation, and function evolution, the product concept function was re-innovated to form a new function to be solved model. Finally, based on RE modelling method of the biological system to search for and sort out biological cases using the established biologically inspired design auxiliary system, the new functions of system-assisted solution were obtained to make product re-innovation schemes. Taking the protective clothing used by medical staff in the shelter hospital as an example, it is verified that the product innovation methods of RE and BID have a good feasibility.
