“…Miura's foldable solar panel is selected from [11] The "scissor" structure is known as one of the joint structures that can be unfolded or closed. Due to the geometric distribution of the scissor structure, the scissor structure can be extended from the motion of a single structural unit to the complex simultaneous movement of multiple structural units [12][13]. (As shown in Figure 4), it is one of the most basic structures in the scissor structure, and the application of this structure can be found in many practical designs.…”

This paper focuses on designing a foldable solar panel that can be folded both circumferentially and radially simultaneously. Most of the existing foldable solar panels have only one movement mode when folded. In contrast, the solar panel designed in this paper has two different movement modes when folded, which has the advantage of further reducing the area of the solar panel when it is fully folded. In this paper, the solar panel can achieve circumferential motion based on the motion principle of the folding fan, and the solar panel can achieve radial motion based on the principle of the slider mechanism. Then the two separate motions are unified by improving the scissors-like element structure. In addition, this paper adopts SolidWorks modeling, CAXA drawing, and calculation to prove the normal operation of the structure. Finally, the control variable method is used to analyze the structural skeleton's radial and circumferential folding capacity. The critical parameter α2 (the central angle when the structure is fully unfolded) is obtained, affecting the mechanism's contracting capacity. When α2 increases, the radial contraction ability of the structure first increases and then decreases, and the circumferential folding ability of the structure continues to increase. At the same time, the radial and circumferential shrinkage capabilities of the structure and the layout of the solar panel are comprehensively considered, and the value of α2 is obtained when the folding ratio is as small as possible.

“…A review of scissor structures based on assembly of scissor units is given by Maden, Korkmaz and Akgün [41]. Recently, Maden et al [42] published a review paper on scissor structures which examines the literature on both unit-based and loop-based design methods and summarizes the different terminologies used in the literature. The paper also proposes a new classification for planar scissor structures according to their motions: 1) scaling/dilation type deployable structures (the angles are preserved but the form is scaled), 2) angular deployable structures (the angles are varied in an arc form), 3) other transformable structures (Fig.…”

Scissor linkages have been used for several applications since ancient Greeks and Romans. In addition to simple scissor linkages with straight rods, linkages with angulated elements have been introduced in the last decades. In the related literature, two methods have been used to design scissor linkages, one of which is based on scissor elements, and the other is based on assembling loops. This study presents a systematic classification of scissor linkages as assemblies of rhombus, kite, dart, parallelogram and anti-parallelogram loops using frieze patterns and long-short diagonal connections. After the loops are replicated along a curve as a pattern, the linkages are obtained by selection of proper common link sections for adjacent loops. The resulting linkages are analyzed for their motions and they are classified as realizing scaling deployable, angular deployable or transformable motion. Some of the linkages obtained are novel. Totally 10 scalable deployable, 1 angular deployable and 8 transformable scissor linkages are listed. Designers in architecture and engineering can use this list of linkages as a library of scissor linkage topologies.

“…This classification for the transformation types is followed in this study as well. transformable (Maden et al, 2019) This study classifies and systematically analyzes assembly of suitable loops for planar deployable structures comprising SLEs. According to the authors' best knowledge, this is the first full classification of scissor mechanisms considered as loop assemblies.…”

Scissor linkages have been used for several applications since ancient Greeks and Romans. In addition to simple scissor linkages with straight rods, linkages with angulated elements were introduced in the last decades. In the related literature, two methods seem to be used to design scissor linkages, one of which is based on scissor elements, and the other is based on assembling loops. This study presents a systematic classification of scissor linkages as assemblies of rhombus, kite, dart, parallelogram and anti-parallelogram loops using frieze patterns and long-short diagonal connections. After the loops are multiplied along a curve as a pattern, the linkages are obtained by selection of proper common link sections for adjacent loops. The resulting linkages are analyzed for their motion and they are classified as realizing scaling deployable, angular deployable or transformable motion. Some of the linkages obtained are novel. Totally 10 scalable deployable, 1 angular deployable and 8 transformable scissor linkages are listed. Designers in architecture and engineering can use this list of linkages as a library of scissor linkage topologies.
