This is a device to exercise the jaw in order to strengthen and shape it. This was a joint design exercise with the client, who is marketing the product himself. It is made with two over-moulded synthetic rubber parts.

My work covered the steps from concept to manufacture:

- Concept ideas

- Market research

- CAD design development

- Prototyping 

- Testing

- Design for manufacture

- Organising manufacture

- Liaison with manufacturers during the moulds construction

- Checking samples and implementing improvements 

Jaw exerciser

The product is designed to be made with two components in two different hardnesses of injection moulded Thermoplastic Elastomer. This permits adjusting the resistance against the jaw pressure in different parts of it.
