An Old Simple Gadget Made New By Biomimicry
The thumbtack, or 'drawing pin' as it was first named by the British, was invented more than a century ago. It is so simply designed, it's hard to think of how it could be improved... unless you happen to stick a few fingers into a box of these pins to try to pick one out just one from the pack. Ouch!
Designer Toshi Fukaya was determined to make the pins just a bit safer! He redesigned the thumbtack using a biomimetic model: a cat. Cat claws, to be specific.
A cat can expose or withdraw his claws, and so now can Fukaya's new biomimetic design of a thumbtack that, by the way, was the winner of a 2011 Red Dot Design Concept award. Covered by a hollow silicone sheath, the pin is not exposed until it's pressed onto a hard surface like a board or a wall.
There you go! A redesigned thumb tack, made safer by biomimetic design.
