When Gregor Bruhn moved his cabinet- and furniture-making business Hand Werk from Germany to Canada, he brought with him tens of thousands of Euros' worth of state-of-the-art German manufacturing machinery. But it was a humble-looking wooden object that most caught the eye of Matthias Wandel, the woodworking scientist behind Woodgears, when he paid Bruhn's shop a visit (and thankfully for us, he shot video). Check out the slick hinge linkage on Bruhn's tool chest and watch what it does:
Amazing, no? And after viewing that video above, where Wandel deconstructs how the hinge works, two young carpenters from Brazil decided to see if they could make their own. David Zimmerman Júnior and his pal Jean Pierre Lana sent their results in to Wandel, who shared it with the rest of us. Check out the video of Zimmerman and Lana's impressive creations that incorporate their version of the dobradiças inteligente:
Pretty damn impressive, considering these guys were just 22 and 21 when they whipped these things up.
