This paper concerns non-developable folded plate structures. It presents the translational method; a design technique that creates threedimensional non-developable systems that can approximate any surface made by translating a generic curve along another generic curve. The continuous folding process is guaranteed by keeping the value of dihedral angles throughout the structure constant at each phase. Once solved the kinematic constraints, the lengths of sides are opportunely varied to approximate any translational surface. The translational method allows for free setting of the target curvature, the approximation span, and the sharpness of the plates.

“…Instead, most practical applications require that folding happens at the fold lines only, without deformation of the material in-between. This condition is called rigid folding; the constraints of which have been studied, among others, in [12] and [13].…”

“…Many studies have thus maintained states on the way to full development or to full folding [12][13][14][15][16]. As above,some expandable structures are already widely available on the market, but they are expected to be applied in more wider ranges of fields, e.g.…”

An origami structure has the advantage of being light yet stiff and expandable. Some expandable structures are already widely available on the market, but although many have attempted to develop a polyethylene terephthalate (PET) bottle that is foldable in the axial direction without bending, such bottles are not yet on the market. The present work thus aims to develop a PET bottle that easily folds without bending. The initial model is generated with seven layers, of which five layers (i.e., excluding the lid and bottom) are set as spiral cylinder. This model can be folded rather easily without bending. However, the model springs back to almost its original height after compression. Thus, we develop new types of PET bottle with two or three spiral layers to resolve this spring back issue. Our new design can insert the foldable layer into a non-foldable layer, such as a conical shell or cylindrical shell, to suppress the spring back after compression. Additionally, grooves between foldable and non-foldable layers in our new designs can further contribute to the trapping of foldable parts. Moreover, our new design can achieve partial compression to reduce the height of the bottle when the liquid is partially consumed.

“…Fundamental results about the behaviours of zero-curvature near creases and apices of arbitrary cones, which are analogous to those of edges and vertices on objects bounded by plane surfaces, were presented by Huffman [18]. Then, Yellowhorse and Howell [19] proposed design guidelines for obtaining additional mobility in a crease pattern by adding creases, removing panels, and splitting creases. Furthermore, approaches for determining the position and number of requisite alterations were described.…”

An origami-inspired cube pipe structure with bistable anti-symmetric CFRP shells driven by magnetic field

This paper proposes a novel origami-inspired cube pipe structure driven by magnetic force, and investigates its deformation and trigger force using experimental and numerical methods. The cube pipe is made of polyethylene terephthalate and its hinge parts are attached by bistable anti-symmetric carbon fibre-reinforced polymer shells with magnets. The magnetic force is generated by an electromagnet and applied on the shell’s curve edge, which implements the stable state transformation of the bistable shells as well as that of the cube pipe. The required magnetic force for the snap-through process of the structure is experimentally obtained and the results agree well with the finite element results. This novel origami pipe can be extensively used in engineering fields, owing to the fact that the stable state can be transformed by a noncontact method and it can be maintained without external force.
