N2 - The subject of this research is the study of the retraction change mode of deployable scissor grids based on the Hoberman mechanism. The retraction logic of this type of flat mechanism can be changed mainly by moving the pivot point of the rod and using bistable deployable scissor structures consisting of translational units. Therefore, the mechanism can remain flat while it retracts, and the irregular translational units allow for a greater variety of surface variations in the shape of the mechanism. Through the study of the scissor system, a simplified mathematical model is used to explore the geometric potential, and a formula for complete flat retraction is derived. Following the input of defined data using digital tools, the remaining translational scissor units that conform to the retraction logic are generated. Then, irregular linkage mechanisms are created that can retract from 3D to 2D, with the opening mode not being limited to the radial sphere or other mean geometries. These results provide a unique retraction mode for deployable scissor grids, thus facilitating the collection and transportation of such mechanisms in practical applications.
