Origami structures hold promising potential in space applications, such as ultra-large-area solar arrays, deployable stations, and extra-terrestrial modular foldable buildings. However, the development of thick-panel origami has been limited, relying on a few typical patterns without comprehensive design theory for multi-crease, multi-vertex configurations. Additionally, realizing closed Polyhedra presents substantial challenges. Here, we introduce methodology inspired by kirigami principles one-degree-of-freedom (one-DOF) flat-foldable origami-kirigami structures, including scalable arrays polyhedral structures. The incorporate mixed four-crease vertices (2n + 4)-crease vertices, enabling one-DOF flat-foldability expansion units. tetrahedrons, square pyramids triangular prisms, possess inward-flat-foldability structural closure after unfolding. This novel framework is capable from centimeter to meter scale, validated kinematic analysis prototype experiments.

Reprogrammable curved-straight origami: Multimorphability and volumetric tunability

Science Advances, Год журнала: 2025, Номер 11(17)

Опубликована: Апрель 23, 2025

Existing origami patterns can transform flat sheets into curved surfaces or be stacked volumetric lattices with tunable properties. Their folded surfaces, however, cannot morph other rigid states, and their three-dimensional (3D) tessellations allow stiffness tuning only through large size variations, causing abrupt shifts in affecting properties such as relative density. These limitations hinder use reprogrammable structural materials real-life applications. Here, we introduce a integrating straight bistable creases to address both challenges: attaining rigidity while allowing reversible remorphability numerous load-bearing shapes generating 3D curved-plate lattices, delivering prescribed configuration of fixed dimensions continuously elastic moduli spanning two orders magnitude. Leveraging theories, differential geometry, paperboard models, experiments, construct the pattern, formulate its geometric mechanics, quantify mechanical performance. Our approach provides versatile platform for multifunctional metamaterials, enabling adaptive resilient aerospace, biomechanics, soft robotics.

Kirigami-inspired rigid-foldable meta-structure with a bidirectional self-locking property

Proceedings of the Royal Society A Mathematical Physical and Engineering Sciences, Год журнала: 2025, Номер 481(2315)

Опубликована: Июнь 1, 2025

Self-locking is an attractive feature in origami structures that enables the foldable structure to withstand loads along direction of deployment, without requiring extra locking elements. However, this rarely observed rigid because such can be easily folded or deployed deployment direction. Here, we introduce a novel meta-structure with both foldability and bidirectional self-locking capacity based on kirigami-inspired icosahedron. The kinematic analysis demonstrates icosahedron has two motion steps separated by bifurcation point. By stacking icosahedra together, construct rigid-foldable module capable bearing tensile compressive deployment. Through energy prototype experiments, demonstrate phenomenon originates from multiple torsional stiffness creases. We arrange into planar array show its potential application mechanical memory storage devices. This work paves new way design structures.
