They are the starting point for new solutions: transformable M-SLE. It has been proved possible to obtain different formal alternatives with a single structural solution, by making modifications to add a DOF (degree of freedom) to the SLE base unit. In this research a new transformable typology is studied: telescopic bars, articulated in x. This proposal, based on the new MP-SLE (modified prismatic SLE) typology, combines two mechanisms of transformation: the scissor system with telescopic bars. It should be able to offer a wide variety of shapes without changing the span to cover, and unlike foldable structures, with only two stable positions, the new proposal offers several intermediate configurations.

In the following examples one can observe that traditional tensegrity tendons are replaced by membranes, which is the main contribution of this work that finds geometry and its constructive method of the different prototypes with the help of software like AutoCAD and WinTess (a software development by Ramón Sastre), which verifies the structural equilibrium. Keywords: Tensegrity unit, formfinding (continuous membrane pattern and diamond pattern, in simple layer and double layer), constructive method, pretension.
