Define the product
An Amazon seller wanted to expand its range with three cable designs. The starting point was a set of ideas, including an angled USB-C to USB-C cable with an extended strain relief.
Resolve design details
Sales and engineering reviewed the requirements together. For a design with a breathing light, Weisi recommended reducing the brightness to avoid unnecessary light distraction.
Review models and samples
The structural design engineer prepared 3D models and renderings for customer review. After model confirmation, the team arranged 3D sampling and validation before mould development.
Move into production
By November 2026, all three designs had entered batch production. The project used USB 2.0 designs; the final cable length confirmed by the factory was 2 metres.
Planning a similar project?
Start with the intended use, required connectors, target length and appearance references. Include lighting, connector orientation and packaging requirements early so the team can discuss design scope and sample review points.
