Zamak Die Casting Since 2005
Customer Requirements (Week 1)
The client requested a new type of strap adjuster based on the traditional tri-glide structure — redesigned to combine the functions of a hook and a tri-glide adjuster.
The product should be able to connect both ends of the shoulder strap while also allowing length adjustment.
Challenge:
- The traditional tri-glide adjuster is simple but cannot be quickly detached.
- The new design needed to achieve a reliable detachable mechanism while preserving the clean, integrated appearance of a traditional strap adjuster — and prevent loosening or deformation during frequent use.
Solutions & Iterations (Week 2 – 4)
After multiple design iterations and discussions with the client, the team identified the key upgrades required to evolve from a traditional tri-glide to a detachable quick-release strap adjuster:
Final Design:
A spring-loaded quick-release strap adjuster that integrates both the hooking function and the length-adjustment function. Upgraded from a sealed rectangular form to an “8-shaped spring gate structure”, which allows the adjuster to open simply by pressing and automatically close when released.
