M O D E L - T:
Veterinary Prosthetic 3-point system

The MODEL-T Prosthetic System was designed to restore mobility and comfort for patients with rear-limb amputations. The goal was to create a modular, anatomically-driven system that adapts to each dog’s unique body structure while maintaining natural movement and stability.

Working alongside the design and fabrication teams, I helped evaluate the existing MODEL-T system for usability, aesthetics, and manufacturability. My goal was to bring the system’s form and finish closer to OrthoPets’ current design standards while maintaining the biomechanical integrity of the original model.

Design Brief

System Components

  • Liner: A custom-fit interface for the amputated limb, providing a soft, protective layer between the animal’s skin and the hard shell.

  • Shell: A vacuum-formed plastic shell designed to encapsulate the liner, offering durability, structure, and support.

  • Spine Plate: A lightweight component positioned along the animal’s spine, padded with 1/8"–1/4" foam for comfort and stability.

  • Femoral Cuff: A contoured cuff with an integrated liner that secures around the upper thigh for additional support and controlled motion.

The process began with capturing an accurate impression of the patient’s limb and recording all key measurements. These physical references were used to develop a fully parametric 3D model of the prosthetic system — ensuring the geometry aligned with both the patient’s anatomy and OrthoPets’ internal production standards.

Design & Development Process

The 3D model was separated into four key parts to study fit, structure, and assembly relationships.

These modeling stages allowed me to evaluate clearances, hinge alignment, and component transitions before fabrication — helping bridge the gap between digital modeling and hands-on production.

Visulization

To communicate the intended visual identity, I produced renderings showcasing the system’s proportion, hinge articulation, and carbon-fiber finish — illustrating how the Model-T aligns with OrthoPets’ future design direction..
