DESIGN & ASSEMBLY · FALL 2026

A compact winch with a 3 V motor.

My contribution: Selected the gear ratios and spool radii using torque and speed calculations, and contributed to the team's CAD model. The design includes 60:1 and 90:1 reductions with interchangeable spool sizes.

Prototype: Our team built the winch with 3D-printed gearbox components. The photo shows the assembled gear train, frame, spool, and drive motor.

Next step: Continue load testing and refine the gearing to meet the competition requirements.

Propeller casting analysis

Comparing riser feeding, solidification time, and hub porosity in SOLIDCast.

View project

Evaluate how adding a riser affects feeding, solidification time, and shrinkage porosity in a propeller casting.

My contribution
Evaluated two supplied casting geometries in SOLIDCast and examined material-density and solidification-time results to assess riser feeding and hub shrinkage.
Engineering decision
Used density and solidification-time plots together to locate late-solidifying hub regions and assess whether the added riser addressed the shrinkage defect.
Outcome
The maximum simulated solidification time decreased from 8.86 to 6.69 minutes, approximately 24%. The sampled hub density changed from 64.34% to 63.72%; the low-density region remained. The revised design therefore required further development.
Next iteration
Recommended evaluating changes to riser size or position, or adding a local chill near the hub to alter the solidification sequence.

Maximum time decreased 2.17 min (approximately 24%). Sampled hub density decreased 0.62 percentage points. Low density persisted in the hub, so the riser required further development.

Project Management Intern · Building Automation Systems

  • Electrical planning: Calculated equipment VA loads from controls and MEP drawings, selected transformer capacities, and assigned circuits based on electrical limits and cost. Documented the plan in Excel and marked-up drawings, and coordinated installation feasibility with electricians.
  • Alarm review: Audited approximately 1,000 BAS alarm points by comparing drawing requirements with existing alarms in Excel. Worked with project engineers to resolve discrepancies and produced an alarm plan approved by the engineering manager for client delivery.
  • Controls training: Wired relays on a low-voltage training board and completed written controller-logic exercises for temperature-based actuator control.
