Background & Design Requirements

The client came to Design 1st wanting to transform the concept of a detachable clip-based wearable activity tracker with visual cues into a high-volume manufacturable product.

Design and Engineering Challenges

Implementing Design 1st’s proven process, the team was able to overcome several obstacles to balance the design requirements with long-lasting performance.

Testing of multiple plastics and features to achieve a durable clip that can be easily detached from device
Battery selection to achieve 16-hour life, with size that would be meet the required slim profile design
Selection of annular light pipe to spread beams evenly for real-time visual interaction during fitness activity

Product Testing: Issue Found

During pre-production prototype testing the material of the poly-carbonate material chosen for the detachable clip began creating problems and failing.

Users testing the device found it was difficult to detach due to friction, resulting in some devices breaking.
But by adding a lubricating compound called Lubriloy™ to the plastic, the clip attachment worked smoothly
A small low-volume production run and user test confirmed the additive lubricant fixed the issue
