用户需求映射网络生物文本的创新设计方法

Innovative design method of mapping from user needs to internet biological texts

仿生创新设计是指通过提取自然界中的生物信息来进行产品的创新设计,具有广阔的应用前景。传统的仿生创新设计方法大多基于少量生物信息,难以对大量生物信息进行高效的资源检索,且会因受到设计人员思维及相关专业知识的局限而难以产生富有创新性的设计方案。为解决上述问题,需提出一种基于网络环境中大量生物文本的集成式创新设计方法,以辅助设计人员进行仿生创新设计。基于此,提出一种通过用户需求映射网络生物文本来获取多学科需求、多映射目标设计方案的创新设计方法。首先,基于神经网络模型提取网络生物文本中的知识并存入数据库;然后,根据提出的多学科需求映射方法得到产品设计的关键词,并用模糊映射方法将产品设计的关键词映射到网络生物文本中,由网络生物文本得到工程设计解;最后,根据上述方法编写程序及设计相应的用户界面,并以管式空气加热器的创新设计为例来验证所提出的方法的可行性。结果表明优化后管式空气加热器的加热效果明显提升,说明所提出的方法可以较好地解决传统仿生创新设计中生物文本信息少、设计人员受自身思维限制且缺乏跨学科专业知识以及生成的产品方案不理想等关键问题,可有效地辅助设计人员完成产品的仿生创新设计。

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 multidisciplinary 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.
