CHARJ - Bluetooth Headset Wireless Charging Dock
Enclosure Design Contract, November 2018
Qi-charging system designed for bluetooth headphones with a generalized charging block
Created two iterations of enclosures based on client requirements and internal electrical components
Presented concept sketches to communicate design direction
Designed for lower volume 3D printed production
Created photo-realistic renderings for marketing and presentation materials
Rush project: started and completed in 1 week
Stage 1 - Concept Generation and Development
Quick deliberation with the client on use case, user experience, and functional requirements.
Presented several thumbnail concepts and a developed idea that was translated from sketch to 3D model on Solidworks.
Stage 2 - Product Refinement + Design for Fabrication
Internal components were changed to allow for a more compact design. The final product was intended for a 3D printed alpha prototype, and several features were added to optimize user handling and wear.
The final design implemented a wedge lock system on four posts around the Qi transmitter PCB, with the transmitter coil mounted on the inner surface of the top cover with a 1.5mm material gap between the coil and the receiver inside the headphones.
Design features included a raised bed for the transmitter PCB to sit on that encouraged ventilation for internal heating and protection. A “skirt” was also designed from the top cover to hide any gap between the top and bottom covers when closed.
Stage 3 - Product ID + Rendering
Thank you for viewing,
