Engineering Capstone

For my senior capstone project, my team and I developed an end-to-end engineering solution to a real-world problem. We began with field and user research, using journey mapping to uncover user needs. We conducted benchmarking to identify gaps in existing solutions, then brainstormed, prototyped, tested, and iterated to develop a high-fidelity prototype ready for market consideration.

Our team addressed the issue of electric scooter theft. We discovered that many riders preferred bringing scooters indoors—despite safety restrictions—due to a lack of secure outdoor locking options, with bike racks proving unreliable after multiple thefts.

This video demonstrates our final prototype in action.

Problem Statement

University students’ electric scooters are being stolen despite attempts to secure them outdoors, causing financial and emotional burdens.

Design Considerations

After interviewing scooter riders to identify security concerns and preferred locking methods, and consulting with the university’s Facilities Department to understand policy requirements and campus constraints, we established the following key design needs.

Concept Development

Created low-fidelity mockups to explore locking mechanisms and usability.

“The Locker Box”

“Rotating Lock”

Project Leadership & Execution

  • Highly Secure

  • Quick, Intuitive, and Easy to Use

  • Compatible with all Scooters

  • Compliant with Bike Rack Standards

  • Low Maintenance

“Stationary U-Lock”

Prototyping

“Stationary U-Lock”

“Front & Back Wheel Lock”

Conducted performance & user testing to compare concepts to existing racks, refining for robustness, ease of use, and security confidence.

Combined successful elements into a CAD-designed prototype meeting key criteria: durable, weatherproof, universal compatibility.

Machined and assembled a functional prototype based on MVP findings.

Refined the design where necessary to ensure a functional and manufacturable solution.

Created exploded drawings of more complex sections to promote repeatability.

Led team as primary designer, machinist, and project manager.

Managed project timelines using Gantt charts & RAM matrices.

Coordinated design, testing, and machining to ensure efficient iteration cycles.
