A product developed to provide assistance with facial exercises for stroke sufferers.
The project brief called for a solution that would allow the user to insert a product into their mouth, and perform a series of exercises to strengthen facial muscles using both lateral movements and opening/closing of the mouth. A concept was proposed that used a dual material design. Rigid plastic sections provided grip and structure to the product, and an overmoulded rubber skin provided 4-way hinge points.
CAD development focused on the size and shape of the product, and the positioning of the hinged sections to ensure it could be compressed and stretched in the desired manner to achieve the excessive goals.
Prototypes were created using a vacuum casting technique that allowed for the overmoulding of the rubber sections onto the rigid plastic sections.
