Redesigned the triceps rope attachment to reduce rope wear while preserving natural movement—validated with load assumptions and manufacturer-ready drawings.

Starting Point
The problem Standard triceps ropes use a metal “divider” that slowly frays the rope at the apex, causing uneven loading and early failure.
Key requirements
Reduce rope wear at the apex
Match (or improve) the original exercise motion
Keep manufacturing efficient and scalable (low custom complexity)
My Contribution
Translated the brief into clear, manufacturable design constraints (motion first, durability second).
Developed multiple attachment concepts and compared them by durability, manufacturability, maintenance, and movement.
Investigated off-the-shelf joint options, contacted suppliers, and aligned the design around a realistic sourcing path.
Ran quick load-case sanity checks (high safety margin assumption) and iterated geometry to stay strong without over-engineering.
Delivered production-ready CAD + drawings so the client could quote and manufacture immediately.
