Structural, Deployable Folds — Design and Simulation of Biological Inspired Folded Structures

“…In this research, we focus on the use of modified polyethylene terephthalate (PETG) as a substitute for paper.The fold patterns were developed primarily to meet kinematic requirements, so that the folded structure would not be overly deep and could be stowed in keeping with the original concept developed by Kurakawa. PETG was selected as a material due to its high deformation capacity with the idea that the hinge could be made inherent in the material as opposed to as a kinematic add on.The scaling experiments in an earlier paper by the authors show that this is not feasible [15].…”

Transformative Solar Panels: A Multidisciplinary Approach

“…Kinetic structures consisting of rigid bars and/or plates connected by revolute joints -also known as deployable, retractable or expandable structures -are intriguing motion systems that can be packed very small and expanded uni-directionally or omni-directionally to a predetermined size and shape, providing greater surface area and enclosed volume. As Joseph Clinton defines "mechanically expanded rigid systems are made up of rigid components compacted into a small package which upon signal rearrange themselves to provide for greater surface area and enclosed volume" [11].These systems have a wide range of applications from solar panels and lightweight antennae for satellites to large-span roof structures and consumer products such as toys or lamps [12] [13] [14].There are different types of kinetic structures classified based on their structural configurations, often with a single degree of freedom.These structures, such as angulated scissor-like frame elements invented by Hoberman [15], were also extended into structures in which their bar elements were covered or replaced with rigid planes [16]. Based on the Clinton's description there are six concepts considered as applicable to rigid expandable structures: telescoping concept, folding concept, fan concept, umbrella concept, variable geometry concept, and finally geometric transformative concept [11].The ᭣ (Figure 3).…”
