Ratchet Wheel For Laces

We're going to create a systeme for tying shoelaces with a easy way. This will be a ratchet wheel system that allows users to tie their shoe

The laces system is gonna be composed of four main pieces : a base, a ratchet wheel, a spool and a rod.
To tighten his laces, Diego just has to turn the wheel in one direction so that the laces wrap around. And to untie them, he'll have to lift the hook, which will release the tension and the laces.

We want to help diego tie his shoelaces more easily.

Inspired by the lacing system on boa snowboard boots. We began by investigating how ratchet wheels work, and obtained a 3d model. 

Once that was done
But before trying out this model on a 3d printer, we made drawings and 3d models using cardboard.
The cardboard was too fragile to withstand the force exerted by the rubber band, so we replaced the cardboard components with wooden ones.
after a few modifications, the ratchet-wheel mechanism works very well.

    Finished the 3d schematics of all the components. We assembled prototype out of cardboard and then out of wood. Next step is gonna be 3d printing.

    Finding the idea out of a snowboard shoes inspiration of the brand boa. We did researches about the system needed and the size of it so we asked a lot of questions to Diego and measured his shoes.
