Miura-ori ( Japanese ミ ウ ラ 折 り ) is a rigid folding scheme that was used to deploy large solar array installations on space satellites . She was introduced by Japanese astrophysicist Koryo Miura in 1970 . Now it is also used for folding paper documents, in particular maps of the area. Unlike conventional card folding methods, the folds of the miura-ori are not perpendicular, but slightly inclined towards each other. As a result, such a card can be expanded and collapsed in one motion, and the absence of multilayer folds reduces the load on the paper. This is a good example of the practical importance of hard origami , considering folds as loops connecting two flat, absolutely hard surfaces.
