It’s World Origami Day! Did you know that the art of paper folding has applications in engineering? Biomedical engineering, robotics, space structures and more use techniques from origami.
Origami dates all the way back to Song Dynasty China (905-1125 CE), but you may not recognize it as the art form it is today. Many defining aspects of the practice including starting with a square piece of paper and a ban on cutting were part of European influence in the mid-nineteenth century. In fact, the activity of folding paper wasn’t known as origami until the late Showa Era in Japan (1926-1989).
Using origami techniques, engineers can solve problems, like fitting big things into small spaces. For example, in this video you can watch how folding techniques allowed for NASA engineers to fold the sunshield for the James Webb Telescope. The sunshield, at 60×46 ft., along with the massive mirror, which measures over 21 feet wide, are much too large to fit into any existing rockets, so engineers used origami-style folding to fit the telescope into the Ariane V Rocket.
Origami can be used to solve much more mundane earth-side problems as well. Architect Anton Willis moved into a new apartment and didn’t have enough space to store his kayak. He solved his problem by creating Oru Kayaks, fully functional and portable kayaks that fold up to be carried or stored.
Biomedical engineering can also get involved! Because of the nature of origami-based design, products are scalable, so the same principles that fold up a tennis court-sized sunshade can also design a heart stent that can be deployed with minimally invasive surgery.
