Abstract
The paper presents a novel concept of a foldable structure named “octa-box.” The structure is composed of: a) a collapsible frame composed of rigid linear members, and b) surface elements attached to the frame. The foldable structure can assume various geometric configurations ranging from a planar one, in the form of an octagon, to a spatial one, in the form of a cubic shape. The integration of both soft and hard surface elements on the frame have been explored and discussed in the paper. Accordingly various origami membrane folding patterns have been considered and explored with the assistance of both physical models and kinematic simulation procedures appropriate for origami membrane structures. Furthermore the geometric concept of a structure composed of a network of octa-box foldable modules has been studied and presented in the paper. In this structure a soft surface of hypar- shape is attached to each module while the orientation of adjacent modules derives from a topological constraint that leads to a connection pattern that runs throughout the structure. Several concepts of transformable frames that form networks of hollow cubic forms have been explored. Examples of potential recreational and environmental architectural applications based on the origami shaped surfaces and the geometric properties or parabola, are included.
