Overview
Product: IoT-enabled consumer electronics designed for integration with glasses
Project Goal: Create new product charging case
Responsibilities:
Develop prototype ID file for current charging case
Prototype nose bridge securing mechanism
Experiment with various button configurations to refine design
Project Challenges:
Navigating design constraints within a compact framework
Ensuring design decisions align with requirements from Luxottica
ID File
Meta partnered with Luxottica to integrate their smart frames design with the Ray-Ban product line. With this decision, Luxottica requested that the frames closely match their existing Ray-Ban carrying case. To help the team understand how much space would be available for our retention mechanisms, I was tasked with recreating the provided ID STEP file into a functional engineering version for our internal use. This version includes both the outer soft leather shell and the internal hard shell.
Nose Bridge Retention Mechanism Design and Prototyping
The main task for this product was to create a retention mechanism for the frames that minimizes rocking and secures the frames from any jostling. Each team member was tasked with developing a prototype to meet these requirements. I designed a purely mechanical solution that snaps onto the unused nose bridge area of the frames and is secured with a torsional spring.
The challenges with this design included:
designing a snap ledge on the frames
determining the effective snap head angle
tuning the spring
Ultimately, this was the chosen retention mechanism design for the frames, and it was further refined by other team members.

In developing the charging case, I was asked to create a button testing strip to evaluate different button configurations within the available space. The options provided were:
No medium
~0.1 mm plastic film medium
~0.5 mm thick plastic medium
All button configurations were covered with either faux leather or fiber material. Testing determined that the plastic film configuration provided the best tactile feel among the three options.
