一项关于利用图形界面来表示产品内运动传递的研究已经进行，以支持一个创造性的概念设计过程，该过程将功能要求和运动要求分开考虑。在工程设计中，已经提出了许多产品结构的表示来帮助理解设计是如何构成的。然而，这些表示中的大多数仅展示功能，而不能展示设计结构。功能分析图（FAD）提供了一个解决方案。FAD不仅显示功能，而且通过方框和箭头的网络显示物理元素，因此它能够展示各种类型的信息和设计方案。这一特性为FAD提供了一个优势，使设计人员可以联合收割机结合不同类型的信息，包括有用和有害的交互作用，以获得设计任务的概述。本研究的重点是使用圆，而不是箭头来表示机构和机器元件的运动属性的运动功能分析图（KFAD），并探讨在机械设计中利用它的方法。一个商业案例研究的医疗设备的设计进行的援助KFAD和组件数据库，机制和机器元素分类（MMET），说明了这一过程。设计结果表明，遵循所提出的概念设计过程是可行的。借助KFAD和机器元件分类，可以考虑运动，从而实现多样化的考虑和设计解决方案。Copyright © 2013 by ASME
A study on utilising a graphical interface to represent movement transmission within products has been conducted to support a creative conceptual design process that separates the consideration of functional requirements and motion requirements. In engineering design, many representations of product structure have been proposed to assist in understanding how a design is constituted. However, most of these representations demonstrate only functions and are not able to demonstrate design structure. Functional Analysis Diagrams (FAD) provides a solution for this. An FAD shows not only functions but also physical elements by the network of blocks and arrows and thus it is capable of demonstrating various types of information and the design scheme. This characteristic gives FADs an advantage for designers to combine different types of information including useful and harmful interactions to gain an overview of the design task. This study focuses on using circles instead of arrows to represent movement attributes of mechanisms and machine elements in a Kinematic Functional Analysis Diagram (KFAD) and explores methods of utilising it in mechanical design. A commercial case study of medical equipment design conducted with the assistance of KFADs and a component database, mechanism and machine elements taxonomy (MMET), is described to illustrate the process. The design outcome shows that it is feasible to follow the proposed conceptual design process. With the help of KFADs and the machine elements taxonomy to enable consideration of movements, diverse considerations and design solutions are possible.Copyright © 2013 by ASME
