Wearable Armband with Synchronized LEDs Design

# Wearable LED Safety Armband Concept Design

I am developing a synchronized LED safety lighting system for walking, running, and bicycling. Multiple wearable armbands and bicycle lights blink in synchronization using wireless communication between ESP32 devices.

I am looking for industrial designers, wearable product designers, CAD designers, or product visualization specialists to propose concepts for the wearable armband portion of the system.

## Project Goals

The armband should:

* Look modern, athletic, and professional
* Be comfortable for walking/running/cycling
* Provide high nighttime visibility
* Support synchronized LED lighting around the visible perimeter
* Be more rigid and structured than standard phone armbands
* Be practical for prototyping and future manufacturing

## Current Hardware

* Custom ESP32-based electronics
* Rechargeable LiPo battery
* WS2812/SK6812 LED lighting
* Silicone LED diffuser

## Key Dimensions

* Electronics module: approximately 58 × 42 × 13 mm
* Battery: approximately 49 × 34 × 6 mm
* LED diffuser: 13 mm wide × 5.1 mm tall

## Design Ideas / Direction

Possible approaches may include:

* Semi-rigid athletic armband
* Flexible band with rigid electronics/light spine
* TPU/silicone hybrid structure
* Recessed LED diffuser channel
* Modern sports/safety wearable styling

I am open to creative ideas and alternative approaches.

## Initial Deliverables Requested

At this stage I am primarily seeking:

* Concept sketches
* Product renderings
* Industrial design ideas
* Wearable structure concepts

Optional:

* CAD concepts
* STL/STEP files
* Prototype enclosure concepts

## Important

Please include examples of:

* wearable product design
* industrial design
* LED products
* sports/safety accessories
* CAD or rendering work

I can provide additional reference images, prototype photos, and videos of the synchronized lighting system.
