01 — A Wearable Charging Solution

We tackled the problem of curved, slender batteries, a flexible PCB, and refined manufacturability by reviewing the sketches, renderings, and early prototypes to identify flaws in both the overall PCB and battery placement design, as well as the basic manufacturability of the unit. By understanding the existing hinge and clasp design decisions, we determined that certain small changes would be mandatory to avoid manufacturing issues.

We engineered custom PCB and battery placement to fit into the design while ensuring maximum charge power and maintaining the overall size. We chose paired, rechargeable 1,000 mAh batteries allowing the QBracelet to recharge in 120 minutes. In addition, we redeveloped the firmware to indicate the charge level of both your phone and the bracelet with four white LEDs. The two PCBs and custom flexible connector fit inside the bracelet and wrap around the curved batteries to allow power to extend from the batteries to the USB chargers.

03 — Product Architecture & Industrial Design

When QDesigns came to Tomorrow Lab, they had a solid industrial design, but could not see how to make their product market-ready. We determined a change in the hinge would allow a full range of motion, and ensured we could get a proper charge at the right angle while keeping the connector safe when not in use. In addition, the QBracelet had to look flawless. The QBracelet weighs only 3.4oz and comes in a small and large size carefully researched to fit a standard women’s and men’s wrist. The outer shell is made of stainless steel with four color options including polished silver and gold, matte silver, and matte black.
