At one time or another in
your life you have probably done origami even if it was just making a paper
airplane or something more complicated like a paper crane. The chances are that
as you did it, you reflected on how inventive this traditional art is. Animals,
boxes, flowers, boats: it all can be created from a single square or
rectangular sheet of paper simply by folding it. No cutting, no pasting.
But did you ever stop to
think how the same techniques might be applied to engineering? Equipment that
could be of real practical use? Origami meets the demand for things that need
to be small when transported and large when they arrive, like the everyday
umbrella. In fact, origami-inspired creations have already flown in space; in
1995, Japanese engineers launched a satellite with solar panels that folded
like a map.
"It's now
mathematically proven that you can pretty much fold anything," says
physicist Robert J. Lang, who quit his engineering job eight years ago to fold
things full time. Lang, an origami enthusiast since age six, advised a advised
well-known ear manufacturer the best way to fold an airbag into a dashboard. He
is currently working on a space telescope lens that, if all goes according to
plan, should be able to unfold to the size of a football field.
At the other end of the
scale, researchers are also working on tiny folding devices that could lead to
breakthroughs in medicine and computing. There's no doubt that computers of the
future may contain tiny, folded motors or capacitors for faster processing and
better memory.
Applications for origami
engineering go further than many of us might imagine. "Some day,"
says MIT's Erik Demaine, "we'll build reconfigurable (可重构的) robots that can fold on their own from one thing into another,
like Transformers. Too much like science fiction to be true? Maybe—though you
certainly wouldn't want to bet against it."
