Starting Point

The client needed a refined mechanical enclosure system for a wearable safety camera with 4G/LTE connectivity and AI processing (Google EdgeTPU), integrating battery, sensors, antennas, and mounts into a compact, rugged form.

Early versions existed conceptually, but the design required refinement for:

consistent assembly logic
battery retention and cover usability
manufacturing feasibility (simplified parts, reduced tooling)
support for accessories (mounts, jacket/bag integration)
clear visuals for suppliers, marketing, and documentation

The enclosure needed to work in both a 4G/LTE variant and a non-4G variant, ideally sharing as many components as possible to reduce manufacturing complexity.

My Contribution

I translated the client’s concept into a fully engineered set of enclosure designs, focusing on:

Battery cover design refinement
- Removed unnecessary fins and crowded geometry
- Proposed combining 4G/non-4G battery cover geometry where possible to reduce tooling and mold count
Internal structural features
- Added internal ribs and supports to secure the battery in larger cover volumes
- Engineered push-support features (thumb/nail push guides) to make the lid easier to open in daily use
Assembly and alignment logic
- Designed alignment features for the silicone insert to ensure consistent placement during assembly
- Tuned screw head clearance and wall thickness for manufacturability and strength
Variant workflows
- Designed both the 4G/LTE enclosure variant and the non-4G variant while preserving shared geometry where possible
- Adjusted dimensions to accommodate supplier feedback on available screws and inserts
Contextual visualization
- Created render sets showing the device on wearable gear:
  - Jacket mount (front/back)
  - Handbag/crossbody integration
- These visuals supported product positioning and helped communicate use cases to stakeholders and suppliers
Documentation support
- Produced edge diagrams and sectional visuals for manufacturing and patent/filing discussions

Final Outcome

The final result is a ready-for-production enclosure package for the SafePro AI PIN wearable security camera, including:

Fully engineered 4G/LTE and non-4G enclosure geometries
Push-friendly battery cover with internal support structures
Alignment features for silicone insert and assembly guides
Adjusted dimensions based on real screw/insert hardware available from suppliers
Marketing and use-case render sets
STEP/STL deliverables ready for supplier review, prototyping, and production

The designs balance functionality, manufacturability, durability, and user ergonomics, tying directly into the product positioning shown on the official product page.
