The Muira Ori Pattern is a simple grid of folding that follows two key rules: the horizontal folds are straight and the vertical folds are diagonal or zigzag. This characteristic means there can be a smooth deployabilit for this structure and that at the vertices of the folds (in architectural, the connections), the intersections displace on another, avoiding friction and stress between them. This means that with the use of hinges, the material would not undergo much less stress than if the two key rules were not followed.
The Yoshimura pattern follows a similar ruling, except there are only vertical folds and diagonal folds to form a diamond pattern. This creates a significant stiffness in the axial direction.
Case Study: Origami Dome
A project created by N. Sugiura, Y. Nakamura, H. Tagawa, T. Uno, and S. Okazaki of the Mukogawa Women’s University for the 4th International Conference of Archi-cultural Interactions through the Silk Road examined how the Yoshimura pattern can be a solid point of reference for structural legitimacy. Their Origami Dome was made of a propylene cardboard of varying thickness that created a small space for people to sit and relax.
