Engineering with Origami !

what is origami:

Origami, from ori meaning "folding", and kami meaning "paper" (kami changes to gami due to rendaku is the art of paper folding, which is often associated with Japanese culture. In modern usage, the word "origami" is used as an inclusive term for all folding practices, regardless of their culture of origin. The goal is to transform a flat square sheet of paper into a finished sculpture through folding and sculpting techniques. Modern origami practitioners generally discourage the use of cuts, glue, or markings on the paper. Origami folders often use the Japanese word kirigami to refer to designs that use cuts.

The small number of basic origami folds can be combined in a variety of ways to make intricate designs. The best-known origami model is the Japanese paper crane. In general, these designs begin with a square sheet of paper whose sides may be of different colors, prints, or patterns. Traditional Japanese origami, which has been practiced since the Edo period (1603–1867), has often been less strict about these conventions, sometimes cutting the paper or using nonsquare shapes to start with. The principles of origami are also used in stents, packaging and other engineering applications

origami used in space:

Did you know that origami has influenced space exploration? Rockets have a limited amount of space inside them, meaning it can be difficult to get large objects out into orbit. Something like the 25-meter solar array shown above would be impossible to safely store inside a rocket at the full size this origami pattern solves this problem by allowing the array to be stowed compactly during launch, then unfolded to its full size once in space. Additionally, since the pieces of the folded design are all connected, electrical circuits can run throughout, allowing for power generation from the panels.

Would you believe that origami can stop bullets? The origami above does just that! Why origami?· Allows barrier to quickly deploy to the complex shape· Allows barrier to be compactly stored it Allows for the barrier to be manufactured flat· For more advantages of origami in engineering, This Instructable will help you create your own paper barrier. In the real barrier, the panels needed to be made of thick bullet-proof material so a variety of thick-folding techniques were used. For more information on the design, see this publication: Seymour, Kenny, et al. "Origami-Based Deployable Ballistic Barrier."

The Miura fold is a method of folding a flat surface such as a sheet of paper into a smaller area. The fold is named for its inventor, Japanese astrophysicist Koryo Miura.The crease patterns of the Miura fold form a tessellation of the surface by parallelograms. In one direction, the creases lie along straight lines, with each parallelogram forming the mirror reflection of its neighbor across each crease. In the other direction, the creases zigzag, and each parallelogram is the translation of its neighbor across the crease. Each of the zigzag paths of creases consists solely of mountain folds or of valley folds, with mountains alternating with valleys from one zigzag path to the next. Each of the straight paths of creases alternates between mountain and valley folds.
