Triceps Rope Attachment design

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.
