Low-Temperature Differential Stirling Engine
Design • Manufacturing • Testing
- Why: Validate mechanical design under real fabrication and assembly constraints.
- How: SolidWorks assembly + drawings; manual lathe and mill machining; assembly and
commissioning.
- Result: Achieved stable operation at 262 RPM, validating tolerance
assumptions and revealing friction/alignment sensitivities.
Key takeaway: small tolerances and surface finish decisions show up immediately in
performance.
Manufacturing & Quality Systems Study – Railway Tracks
Systems analysis • Safety • Standards
- Why: Understand reliability and safety considerations in critical infrastructure.
- How: Reviewed materials, manufacturing routes, inspection methods, and lifecycle
maintenance practices.
- Result: Identified dominant failure mechanisms and compliance risks, reinforcing
preventative maintenance and inspection discipline.
Key takeaway: quality systems are part of engineering design, not an afterthought.
Motor Housing Reverse Engineering – Drill Motor Case
Inspection • Tolerancing • Documentation
- Why: Translate physical equipment into a manufacturable and inspection-ready design.
- How: Extracted functional dimensions; applied controlled fits and GD&T; rebuilt in
SolidWorks with parametric intent.
- Result: Produced a model + drawing package supporting repeatable assembly and
manufacturing handoff.
Key takeaway: clear documentation reduces ambiguity across manufacturing, inspection, and
maintenance.
Dynamic System Modeling – Vehicle Suspension
Vibration analysis • Modeling • System response
- Why: Understand how mechanical systems respond to transient and periodic excitation.
- How: Modeled a suspension system using differential equations and simulated response to
road inputs using numerical methods.
- Result: Interpreted the influence of stiffness, damping, and excitation frequency on
performance and response.
Key takeaway: modeling is only useful when it informs decisions and constraints.
Product Engineering Evaluation – Consumer Appliance
Analysis • Technical reporting • Trade-offs
- Why: Practice objective engineering evaluation and decision support.
- How: Conducted primary product analysis and secondary research across usability,
function, and environmental considerations.
- Result: Delivered a structured technical report summarizing trade-offs and improvement
opportunities for a technical audience.
Key takeaway: good recommendations come from evidence, not opinions.
