Description

Low volume production of wearable devices used in conjunction with HeadCheck Health’s novel concussion protocol software. I worked on the mechanical and electrical design as well as the firmware. Achieved all of this work from scratch in a period of 3 months, hitting the ~$100 BOM cost per unit.

FEATURES

• Designed to IP65

• Design for manufacturing

• Bluetooth Low Energy

• 100Hz accelerometer

• Button snaps for easy removal

Unique Notes

Designing a product like this in such a short timeline can be tough, especially when there is a hard BOM cost target required. This means that not only does the device need to be functional, but one needs to think about design for manufacturing early on and iterate quickly.

Spending more time up front to find the optimal design path means less risk and faster development later on. This required iterating on different attachment mechanisms to the head strap, thinking about mold cavity design when making the enclosure and finding different ways to prevent water ingress while minimizing parts count and thus cost.

Three first revision devices were made using 3D printing and then an order of 50 units were built and programmed for a trial run and study at UBC.
