In our previous post proposing a new kind of auxetic package design, we started with some breathtakingly complex models. That was counter-intuitive, perhaps. Maybe it’s better for us to walk before we run. As amazing as they are, those complex structures are hard to get your head around. It’s easier to grasp these transformations when they’re 2-dimensional.
Toys from Trash
Alison Grace Martin‘s video above is a good place to start. She posted this video as part of her toys-from-trash album on Flickr. She hinged 9 boxes (that appear to be milk cartons) together with tape. In this way, she shows us how we might extrude a 2-dimensional auxetic structure into 3-dimensional packaging. Her kinetic 9-pack of boxes transform in the same way as Adrian Rossiter‘s animated gif of planar “jitterbugging” squares (above right).
How is this a “simpler” approach? Because we are confining our hinged boxes to movements that can be made by polygons in a 2-dimensions plane. This is similar to an idea we’ve suggested before. (See: The Haberdasher’s Package and Chained Polyhedral Portion Packs)
The difference this time, is that we can design multi-packs capable of “jitterbug” style auxetic transformations. A few have already experimented with this idea.
