运动结构综合在机构概念设计中的应用是比较成功的。然而，本文提出的方法，从桁架结构的初始角度来看，设计过程。首先，生成表示具有给定数量的节点和连杆的桁架结构的图。然后通过指定图中的某些边来修改每个图，以表示结构中包含附加自由度的链接。这样，一个结构的图形就转化为一个表示机构的图形。提出了一个程序，使这些图的可部署结构的任何给定数量的节点和链接的穷举生成。从这些图，它是可能的，然后获得可折叠的新的可展开桁架结构，以及那些已被搁置在文献中
Kinematic structural synthesis has been relatively successful when applied to the conceptual design of mechanisms. The approach presented in this paper, however, views the design process from an initial standpoint of a truss structure. First, graphs are generated that represent truss structures with a given number of nodes and links. Each graph is then modified by designating certain edges in the graph to represent links in the structure that incorporate additional degrees of freedom. In so doing the graph of a structure is transformed into one representing a mechanism. A procedure is presented that enables the exhaustive generation of these graphs for deployable structures of any given number of nodes and links. From these graphs, it is then possible to obtain enumerable novel deployable truss structures as well as those that have been reposed in the literature
