产品造型的类比推理式对抗生成设计方法研究

类比推理被视为概念设计活动的核心，如何借助人工智能算法来解析、模拟类推设计机制、并指引产品造型设计过程已成为当前国际上设计学研究面临的新挑战。本项目首先开展类推设计过程的实验研究，阐明多源视觉启发下的产品二维造型的类推设计转换机制，提出模拟类推机制的对抗生成算法，建立融合先验设计信息的产品设计草图的类推生成模型。然后，探究产品设计草图与三维造型流形之间的动态映射关系，建立草图驱动的产品三维造型的混合智能生成模型。进而，在概率隐空间建立产品三维造型流形的演化模型，并通过构建隐空间映射网，为设计师提供类推设计的人机接口，实现产品三维造型的类推式快速建模。最后开发智能设计原型系统，以房车的造型设计为例予以应用验证。本项目的研究成果将提升产品造型设计的效率，激发设计师的创造力，有助于进一步拓展计算机辅助造型设计和智能设计等领域的理论与应用创新，为我国创新设计的发展提供新动能。

Analogical reasoning is the core of conceptual design. How to use an artificial intelligence algorithm to analyze and simulate the design mechanism of analogical reasoning to guide the product form design process has become a new challenge for international design research. At first, an experimental study will be carried out to clarify the conversion mechanism of 2D form analogical design through multi-source visual inspiration, the revised generative adversarial networks based on the design mechanism of analogical reasoning will be proposed, and an analogical generation model of product design sketch with prior information of design experience will be established. Then, the dynamic mapping relationship between 2D sketch and 3D shape manifold will be explored, and a hybrid intelligent generative model of 3D modeling driven by sketch will be established. Furthermore, the 3D shape manifold evolution model will be established in the probabilistic hidden space. The hidden space mapping network will be constructed to provide the designers with the human-computer interface of rapid 3D modeling via analogical reasoning. Finally, a prototype system for intelligent design will be developed, taking the form design of motor homes as an example. The research results of the project will improve the efficiency of the product form design, stimulate the creativity of designers, further expand the theory and application innovation of computer-aided form design and intelligent design, and provide the new driving force for the development of innovative design in China.
