More iteration and production...

Last time, I shared about Untangled and how my students created, designed and printed a device to untie shoelaces.  They redesigned it based on timed trials and made it thinner, even adding an 'ergonomic' handle to it.  While the original was too thick and cumbersome, the redesign was too thin and flimsy.  In the meantime, however, they retimed themselves using the redesign and halved the amount of time it took them to untie difficult-to-undo double-knotted laces.  Not too bad...

Iteration in Process

The student 'companies' in my class have begun working on the product development process.  They have designed and printed their company logos in 3D and now are working on their actual products.  One of the companies called themselves "Untangled" and specialize in gadgets to help with untying those difficult to undo double-knotted laces.  They designed a printed a hook, but it was too flimsy and thin.  They then redesigned their hook on Tinkercad and thickened it all around, printed it again on the Makerbot Replicator 2 and tried it out.  I then recorded the students trying out the new tool after which we discussed what they might need to change in the next 'version' or iteration of the 'untangler.'
