Cut Design of Pop-Up Origami with Fixed Planar Substrate
摘要
Pop-up designs serve as an efficient method for transforming 2D planar sheets into 3D structures. When the substrate maintains its original planar configuration, the design gains the ability to independently extend across the surface. Here, the Rotation Erection System (RES) is employed as the foundational concept to attain localized pop-up behavior. Stretchability analysis is conducted to establish the feasible connection boundary for the predefined rotation erection region. All creases are designed based on the predefined maximum rotation angle, validated through paper models with different geometry designs. Furthermore, the bistability behavior is undertaken from the perspective of incompatibility. This investigation extends to the incorporation of additional creases in the design, aiming to achieve multiple stable states.
