ORIGAMI-SCISSOR Hinged Geometry Method

The diamond origami-scissor hinged pattern marks a new type of thick origami that can not only fold and unfold, but also expand and contract (project below). This was done by applying the ‘form generation method of relative ratios’ for two-bar scissors to the thick origami. This research tests whether this method can be extended and generalized to other types of origami. The origami-scissor hinged geometry method is here applied to the waterbomb of thick panels making a waterbomb origami-scissor hinged pattern. While the waterbomb origami of thick panels has one degree of freedom, the waterbomb origami-scissor hinged pattern has two degrees of freedom as it can independently fold and unfold as an origami, and expand and contract as a scissor hinged structure. This creates a new research branch of expandable thick origami. The ‘form generation method of relative ratios’ (FGMORR) [Rivas-Adrover 17] has been applied to the ‘origami of thick panels’ [Chen et al. 15] because this method to make thick origami can be extended and generalized to different types of origami, and therefore the origami-scissor hinged geometry method can also be applied to all these different types of origami. A critical condition is that the thick origami has to be made of equal or proportional thicknesses so that when translating that geometry with scissors the end nodes match. Another condition is that the pantographs that mark the creases and join different origami faces must have an equal morphology and bilateral symmetry. Automation of this method will be investigated with Grasshopper for Rhinoceros. Origami-scissor hinged patterns provide an extra degree of freedom, therefore origami patterns that could be folded can now also contract and occupy much smaller volumes. This would be useful in applications where a high ratio of deployed-to stowed volume is required such as space applications, earthbound transportable applications, and to create adaptable spaces and transformable environments in permanent architecture

A New Hybrid Type of Deployable Structure: Origami-scissor Hinged

Deployable structures can transform, expand and contract due to their geometric, material and mechanical properties; applications spread across multiple fields including aerospace technology and temporary, mobile and transformable architecture. There are many different types of deployable structures. For instance, the art of origami has developed concepts for paper folds that can expand and contract. Another type is that of scissorhinged structures, made by bars joined by pivots. These two different types, origami and scissors, have so far remained separate types within the field. This geometry research unifies both types and makes an origamiscissor structure, which has a double deployment. This new technology has potential applications in architecture and engineering, such as transportable pavilions, aerospace or robotic applications

Classification Of Geometry For Deployable Structures Used For Innovation: Design Of New Surfaces With Scissor 2 Bar, And Form Generation Method Of Relative Ratios

Deployable structures can expand and/or contract due to their geometrical, material and mechanical properties. This research proposes a classification of geometry for deployable structures. This classification system applied to structures made with scissor 2 bar can lead to architectural innovation. This is demonstrated in the case study of a new design for surfaces based on scissors 2 bar. Through this case study a form generation method of relative ratios is formulated that can be applied to infinite geometrical arrangements. This geometry classification is an attempt to seek further understanding of the subject of deployable structures. In order to gain a comprehensive understanding of this field, different ways of ordering information are being considered

TRANSFORMING ARCHITECTURE MADE WITH SCISSORHINGED DEPLOYABLE STRUCTURES: ALHAMBRA PAVILIONS IN CAMBRIDGE MARKET SQUARE

Scissor-hinged deployable structures, made by units of bars joined by a pivot, can generate large complex lattice structures that can expand and contract. So far scissor-hinged deployable structures had been designed one by one, and scissor hinged surfaces have been made of grid lines made of triangles and squares. The ‘form generation method of relative ratios’ (FGMORR) by Rivas-Adrover can be applied to infinite combinations of lines and can therefore generate infinite scissor-hinged structures with an optimum deployment. This is here demonstrated by applying the FGMORR to a combination of lines from the Alhambra in order to make a new scissor-hinged surface. Also, while so far scissor-hinged technology has been used to generate surfaces, here it has been demonstrated that the FGMORR allows for creating not only the surface or roof, but also its supports. While this research extends the theory of the FGMORR for scissor -hinged deployable structures, it has also given a clear outline of the assembly and deployment strategy, as well as a potential intervention. The Alhambra pavilions in Cambridge Market Square demonstrate that this sustainable technology can embody cultural symbols, and can embrace the concepts of identity, place and culture; this therefore allows a conversation equally relevant that interacts with contemporary life, future technologies, and historical heritage
