项目摘要

The objective of this research is to support the designer's imagination at the preliminary design stage of mechanical products. When the designer makes a first rough design plan at the initial stage, he/she decides on the rough shape and rough dimensions of the functional components of the product, and draws a rough sketch of the product or prototypes. To get the final detailed design of the product, the designer repeats the above design process at an ever increasing level of detail. At the preliminary design stage, it is important for the designer to imagine freely without constraints of preconception. Traditional CAD systems do not support such a divergent thinking process of the designer. In this research, the designer's imagination process is supported by providing various design plans which are automatically created from module layouts. A mechanical product consists of several functional modules, and each module has at least one primitive function. As a mechanism of deployment from functional requirement of a mechanical product to functional modules, a module library is proposed. A module library consists of three classes : the functional requirement class, the primitive function class and the module class. In the module class, each module's layout constraints are described. Mechanical modules which have basic functions to satisfy requirements for the product are chosen and combined using a module library. Various module layouts are automatically generated by applying a genetic algorithm to each of the functional module combinations. The designer knows the rough image of the product based on these layouts. The complete product structure is obtained by connecting modules using connecting parts. Furthermore, a commercially available mechanism-analysis software is applied for determining whether the generated layouts fulfill the functional requirements of the product. A trial implementation of a proposed system is applied to a building kit for toy robots.

本研究的目的是支持设计师在机械产品初步设计阶段的想象力。设计师在初始阶段制定第一个粗略设计方案时，确定产品功能部件的粗略形状和粗略尺寸，并绘制产品或原型的粗略草图。为了获得产品的最终详细设计，设计师以不断增加的细节水平重复上述设计过程。在初步设计阶段，设计师不受先入为主的束缚，自由想象是很重要的。传统的 CAD 系统不支持设计者这种发散的思维过程。在这项研究中，设计师的想象力过程通过提供从模块布局自动创建的各种设计方案来支持。一台机械产品由若干个功能模块组成，每个模块至少具有一个基本功能。作为从机械产品的功能需求到功能模块的部署机制，提出了模块库。模块库由三个类组成：功能需求类、基本功能类和模块类。在模块类中，描述了每个模块的布局约束。使用模块库选择和组合具有满足产品要求的基本功能的机械模块。通过对每个功能模块组合应用遗传算法，自动生成各种模块布局。设计师根据这些布局了解产品的大致形象。通过连接件将模块连接起来，得到完整的产品结构。此外，应用市售的机构分析软件来确定生成的布局是否满足产品的功能要求。所提出的系统的试验实施应用于玩具机器人的搭建套件。
