Four-bar prosthetic knee joint with adjustable hydraulic suspension

Project objective: Design, develop, and validate a four-bar prosthetic knee joint with an adjustable hydraulic suspension system, optimized to reproduce a natural human gait and ready for manufacturing and testing.

Required technical skills:

• SolidWorks CAD (Design & Simulation)
• 3D printing knowledge
• Mechanical part selection (functional and cost-efficient)
• Design for Manufacturing (DFM) and BOM preparation

Required personal skills:

• Engineering rigor and precision
• Analytical and problem-solving skills
• Ability to work independently
• Technical documentation skills

Main tasks:

• Design the four-bar knee mechanism in SolidWorks
• Integrate and validate the hydraulic suspension system
• Perform structural and kinematic simulations
• Prototype a knee model using 3D printing
• Validate knee behavior, stability, and suspension response
• Prepare a complete manufacturing folder
