The morphology of design is the discipline that studies the generation and properties of form. In this case we will study the deployable structures
The basic shape of these structures is called scissors which consists of two bars and a union between them. There are two ways to make these bars, centrally and eccentrically. These differ at the junction point of the bars and this will define the opening shape of the scissors
By joining several bars and placing joints at their ends you can get to play with the creation of various morphological forms
