engineering projects
A collection of my coursework and design team projects from my undergrad in mechanical engineering.
Sprocket Design & Analysis
October - November 2025
Designed a 120-tooth aluminum sprocket for the 2026 vehicle to accommodate a new #25 chain and achieve an 8:1 gear ratio. Conducted mechanical analysis to handle peak startup forces with a maximum motor torque of 1.69 Nm.
Key Specifications
- 120-tooth sprocket with 8:1 gear ratio
- #25 chain (0.25" pitch, ANSI standard)
- Aluminum construction for weight reduction
- Max tooth thickness: 3.08-3.13 mm
- Handles 13.52 Nm torque at wheel
Battery Box Redesign
October - November 2025
Coordinated with the electrical division to design and 3D print a new battery box. Focused on minimizing weight while ensuring battery security, wire clearance, and ease of maintenance. The design features external mounting capabilities and a handle that doubles as a locking mechanism.
Design Features
- 33% reduction in size from previous design
- Integrated handle/locking mechanism
- External component mounting (PCBs)
- Tapered edges for easy battery insertion/removal
- Countersunk screw holes for angle bracket mounting
Chain Tensioner System
November 2025
Designed a new chain tensioner system compatible with aluminum extrusion rails. The tensioner uses a 20-tooth idler sprocket for #25 chain, ensuring proper chain tension throughout the drivetrain.
Specifications
- 20-tooth idler sprocket
- #25 chain compatibility (0.25" pitch)
- Aluminum extrusion rail mounting
- 3D printed components
Accessible High Park Route Design
September - November 2025
Designed three conceptual solutions for an accessible pathway from Keele Subway Station to the High Park Nature Centre. The project balanced accessibility requirements with environmental preservation of the endangered Black Oak Savannah ecosystem and Indigenous stewardship practices.
Design Solutions
- Smart Trail: Modular aluminum ramps with motion-activated audio wayfinding
- The Boardwalk (Recommended): Elevated recycled composite pathway with curved geometry
- Magic Carpet: Motorized conveyor belt for steep sections with crushed limestone trails
Key Requirements Met
- Meets Accessibility for Ontarians with Disabilities Act requirements
- ≤5° slope for wheelchair accessibility
- Multi-sensory navigation (visual, tactile, auditory)
- Compatible with prescribed Indigenous burning practices
- 100% construction within existing disturbed corridors
