【摘要】：概念设计作为产品开发周期的早期阶段,最能体现产品的高效创新。创新的精髓在于为设计者提供理想的产品设计方案。所建立的基于TRIZ(发明问题解决理论)与仿生技术集成的产品创新过程模型能更好地驱动产品概念设计创新。论文主要从冲突问题解决、创新方案设想产生、原理解方案综合与评价等3个方面展开研究。主要研究内容包括：(1)探究了TRIZ解决冲突问题及耦合仿生技术应用的一般过程,建立一种基于TRIZ冲突问题解决方法与耦合仿生技术的冲突问题解决过程模型。同时,利用Matlab软件实现了基于生物功能创新原理的TRIZ冲突问题解决模块的可视化操作。该冲突问题解决过程模型能有效地提高产品创新设计效率。(2)提出了基于生物功能进化与技术进化的产品创新方案产生机理。通过对生物体功能模型的阐述,提出产品生物体功能模型的建立方法。在分析功能进化与技术进化状态间内在联系的基础上,建立两者的关联矩阵。通过计算机实现了3条专利曲线的拟合,完成了产品技术成熟度预测。(3)通过对蚁群算法原理的分析,将蚁群算法应用于方案综合与评价方法,借助Matlab软件对产品形态学矩阵进行组合优化,最终获得了理想的产品原理方案。(4)将冲突问题解决模块运用于轴流风机叶片的工程设计。首先通过对轴流风机系统冲突的分析,利用所编制的软件得到了解决冲突问题的仿生模本；然后通过生物耦元分析提取出轴流风机叶片的仿生耦元结构,并建立叶片结构仿生耦合模型。最后,利用Fluent软件对叶片原型及其进行了流量和噪声仿真分析。研究结果表明：叶片仿生耦合模型的质量流率提升了6%,系统噪声值降低了7.8%。(5)利用上述研究成果,建立新型紫外光油烟净化机系统的总体结构模型,并对紫外光油烟净化机系统在集烟罩、油烟管道、风机等结构方面进行改进。工程实例验证了所提出的基于生物功能进化与技术进化的创新方案产生机理及基于蚁群算法的方案综合与评价方法的适用性和高效性。该课题研究将为产品创新设计方法的拓展性应用及研究提供一定的参考。
[Abstract]:As the early stage of the product development cycle, conceptual design can best reflect the high-efficiency innovation of the product. The essence of innovation is to provide designers with ideal product design schemes. The product innovation process model based on the integration of Triz (invention problem solving theory) and bionic technology can better drive product conceptual design innovation. This paper mainly studies the conflict problem solving, the creation of innovative scheme, the synthesis and evaluation of original understanding scheme. The main research contents include: 1) the general process of Triz conflict resolution and the application of coupling bionic technology are explored, and a conflict resolution process model based on Triz conflict solution method and coupled bionic technology is established. At the same time, the visual operation of Triz conflict problem solving module based on the principle of biological function innovation is realized by using Matlab software. The conflict problem solving process model can effectively improve the efficiency of product innovation design. Through expounding the biological function model, the method of establishing the product organism function model is put forward. Based on the analysis of the relationship between functional evolution and technological evolution, the correlation matrix between them is established. Three patent curves are fitted by computer, and product technology maturity prediction is completed. Through analyzing the principle of ant colony algorithm, ant colony algorithm is applied to project synthesis and evaluation. The optimal product morphology matrix was optimized by Matlab software, and the ideal product principle scheme was obtained. Finally, the conflict problem solving module was applied to the engineering design of the blade of axial fan. Based on the analysis of the conflict of axial fan system, the bionic model of solving the conflict problem is obtained by using the software, and then the bionic coupling element structure of the blade of axial fan is extracted by biological coupling element analysis. The bionic coupling model of blade structure was established. Finally, fluent software is used to simulate the blade prototype and its flow and noise. The results show that the mass flow rate of the blade bionic coupling model is increased by 6% and the system noise value is reduced by 7.8%) the overall structure model of the new ultraviolet oil fume purifier system is established by using the above research results. The system of ultraviolet oil fume purifier is improved in smoke collecting cover, oil pipe, fan and so on. An engineering example verifies the applicability and efficiency of the proposed scheme synthesis and evaluation method based on ant colony algorithm, which is based on the generation mechanism of innovative schemes based on biological functional evolution and technological evolution. The research will provide some reference for the application and research of product innovation design method.
