Potential stylistic directions drawn out in rough.
Design direction selected, movement to design refinement and detailing.
To understand size form and fit in hand.
Three designs selected, mocked up in C.A.D. and rendered roughly using keyshot for a close visual comparison.
Skinning and colouring the handsets.
Combined use of C.A.D. and sketch work to establish feasible manufacture and assembly.
Multiple prototypes from manufacturers used to refine the design up to a pre-production model (shown here).
Tweaks made to the final design to increase surface area for part mounting.
