Enhancing Mobility and Sustainability: An Origami-Based Furniture Design Approach for Young Migrants
Amid accelerating globalization and resource scarcity, rapid urbanization and population mobility have made sustainable development a critical issue for cities. Frequent relocations pose furniture disposal challenges for many young migrants, with high transportation costs and furniture wear increasing their economic burden and resource waste. Origami design effectively addresses these needs with its portability, easy storage, simplified manufacturing, and reduced failure rates. However, most furniture designers lack origami expertise, limiting their ability to leverage these benefits. This study integrates the existing literature and presents a sustainable furniture design method combining Rhinoceros 3D, Grasshopper, and Crane, enabling designers to incorporate origami principles with limited prior knowledge. The results show that this method not only enhances the economic feasibility of furniture but also balances user needs, commercial interests, and environmental sustainability, offering new insights for urban sustainable development.

Engineering Origami: A Comprehensive Review of Recent Applications, Design Methods, and Tools
Origami‐based designs refer to the application of the ancient art of origami to solve engineering problems of different nature. Despite being implemented at dimensions that range from the nano to the meter scale, origami‐based designs are always defined by the laws that govern their geometrical properties at any scale. It is thus not surprising to notice that the study of their applications has become of cross‐disciplinary interest. This article aims to review recent origami‐based applications in engineering, design methods and tools, with a focus on research outcomes from 2015 to 2020. First, an introduction to origami history, mathematical background and terminology is given. Origami‐based applications in engineering are reviewed largely in the following fields: biomedical engineering, architecture, robotics, space structures, biomimetic engineering, fold‐cores, and metamaterials. Second, design methods, design tools, and related manufacturing constraints are discussed. Finally, the article concludes with open questions and future challenges. This article reviews the state of the art of origami‐based applications in engineering. Publications of origami‐based applications are reviewed according to the following fields: biomedical engineering, architecture, robotics, space structures, biomimetic engineering, fold‐cores, and metamaterials. Design methods and tools are also reviewed. Manufacturing considerations are provided and future challenges discussed.

Origami tubes assembled into stiff, yet reconfigurable structures and metamaterials
Thin sheets have long been known to experience an increase in stiffness when they are bent, buckled, or assembled into smaller interlocking structures. We introduce a unique orientation for coupling rigidly foldable origami tubes in a “zipper” fashion that substantially increases the system stiffness and permits only one flexible deformation mode through which the structure can deploy. The flexible deployment of the tubular structures is permitted by localized bending of the origami along prescribed fold lines. All other deformation modes, such as global bending and twisting of the structural system, are substantially stiffer because the tubular assemblages are overconstrained and the thin sheets become engaged in tension and compression. The zipper-coupled tubes yield an unusually large eigenvalue bandgap that represents the unique difference in stiffness between deformation modes. Furthermore, we couple compatible origami tubes into a variety of cellular assemblages that can enhance mechanical characteristics and geometric versatility, leading to a potential design paradigm for structures and metamaterials that can be deployed, stiffened, and tuned. The enhanced mechanical properties, versatility, and adaptivity of these thin sheet systems can provide practical solutions of varying geometric scales in science and engineering.

Origami design secrets : mathematical methods for an ancient art
\"This book is an opus of world-famous origamist Robert J. Lang that presents the mathematical and design principles he uses to create original origami. The techniques are accompanied by folding instructions that illustrate them, building up to very advanced models at the end of the book. The second edition includes three new/highly revised chapters on box pleating, uniaxial box pleating, and polygon packing as well as smaller revisions throughout and improved illustrations\"-- Provided by publisher.

Untethered control of functional origami microrobots with distributed actuation
Deployability, multifunctionality, and tunability are features that can be explored in the design space of origami engineering solutions. These features arise from the shape-changing capabilities of origami assemblies, which require effective actuation for full functionality. Current actuation strategies rely on either slow or tethered or bulky actuators (or a combination). To broaden applications of origami designs, we introduce an origami system with magnetic control. We couple the geometrical and mechanical properties of the bistable Kresling pattern with a magnetically responsive material to achieve untethered and local/distributed actuation with controllable speed, which can be as fast as a tenth of a second with instantaneous shape locking. We show how this strategy facilitates multimodal actuation of the multicell assemblies, in which any unit cell can be independently folded and deployed, allowing for on-the-fly programmability. In addition, we demonstrate how the Kresling assembly can serve as a basis for tunable physical properties and for digital computing. The magnetic origami systems are applicable to origami-inspired robots, morphing structures and devices, metamaterials, and multifunctional devices with multiphysics responses.

Origami tubes with reconfigurable polygonal cross-sections
Thin sheets can be assembled into origami tubes to create a variety of deployable, reconfigurable and mechanistically unique three-dimensional structures. We introduce and explore origami tubes with polygonal, translational symmetric cross-sections that can reconfigure into numerous geometries. The tubular structures satisfy the mathematical definitions for flat and rigid foldability, meaning that they can fully unfold from a flattened state with deformations occurring only at the fold lines. The tubes do not need to be straight and can be constructed to follow a non-linear curved line when deployed. The cross-section and kinematics of the tubular structures can be reprogrammed by changing the direction of folding at some folds. We discuss the variety of tubular structures that can be conceived and we show limitations that govern the geometric design. We quantify the global stiffness of the origami tubes through eigenvalue and structural analyses and highlight the mechanical characteristics of these systems. The two-scale nature of this work indicates that, from a local viewpoint, the cross-sections of the polygonal tubes are reconfigurable while, from a global viewpoint, deployable tubes of desired shapes are achieved. This class of tubes has potential applications ranging from pipes and micro-robotics to deployable architecture in buildings.
