Problem: Hand rehabilitation exercises require devices that can adapt to different finger sizes and provide measurable feedback. I wanted to design a modular system for finger flexion and extension exercises that could improve exercise adherence and comfort.

Solution: I performed literature and patent reviews, then designed a finger slider module in SolidWorks. The two-piece base and slider allows for easy assembly and size customization. I 3D printed the prototype to test fit and function, planning future iterations to integrate sensors like ToF or force sensors to measure position and pressure, with potential translation into a game interface for real-time feedback.

Impact: This project enhanced my skills in human-centered design, mechanical prototyping, and iterative testing. I learned to balance ergonomics, modularity, and future sensor integration for interactive rehabilitation devices.

Problem: Impaired knee motion can limit mobility and slow rehabilitation. I wanted to analyze knee movement in healthy and unhealthy individuals to design a solution that could assist patients in regaining strength and proper motion.

Solution: I used MediaPipe to track knee motion and MATLAB to process data, calculating range of motion (ROM) and angular velocity. Based on this analysis, I proposed a spring-actuated device with an adjustable mechanism to provide additional force, helping the knee move from flexion to extension while tailoring resistance to the patient’s strength.

Impact: This project strengthened my skills in markerless motion tracking, data analysis, biomechanics, and mechanical design. I gained experience in translating motion data into actionable design concepts for rehabilitation devices.

Problem: Designing mechanical components that can withstand applied loads requires understanding motion and stress distribution. I wanted to learn how to simulate and optimize mechanical designs beyond basic CAD modeling.

Solution: I used SolidWorks motion simulation to analyze a crank slider mechanism and generate displacement plots. I also applied finite element analysis (FEA) with mesh convergence to evaluate stress and strain on components. These techniques were applied in a design competition to optimize a yoke design to withstand competitor-applied loads.

Impact: This project enhanced my skills in motion simulation, FEA, and stress optimization. I gained practical experience applying computational tools to improve mechanical designs under real-world load conditions.
