Solenoid-Motor Farm Solution
High-Density Actuator Packaging
Conceptual electromechanical system developed during a biomedical engineering interview process to regulate fluid flow within a compact benchtop device. The design utilizes an array of solenoid actuators driving mechanical linkages to generate approximately 15N per channel within a tightly constrained footprint.
The primary challenge was achieving reliable force output, alignment, and repeatable motion within an overall size envelope of approximately 4 inches. Design considerations included actuator spacing, load paths, mounting tolerances, and assembly accessibility.
The final model emphasizes compact packaging, modular actuator placement, and manufacturable geometry, reflecting realistic constraints encountered in small-scale biomedical hardware development.

Structural Feasibility, Failure Identification, and Redesign
Performed finite element analysis on a compact internal bike lock mechanism subjected to extreme torsional loading representative of extreme real-world pedaling forces (~527 Nm). A simplified, constraint-driven model was developed to evaluate feasibility within tight geometric limits imposed by a bicycle axle envelope.
Initial FEA revealed severe stress concentrations at the gear–pin interface, exceeding material limits (>11 GPa), indicating that the original concept was structurally infeasible. Based on these results, the design was iteratively reworked by increasing load-bearing cross-section, redistributing contact forces, and selecting higher-strength alloy steel.
The redesigned configuration reduced peak stress by over 80%, bringing the system within realistic material limits and demonstrating how FEA can directly inform design decisions, scope changes, and mechanical viability under real-world constraints.

Mechanical Subsystem Integration
Designed a complete mechanical pencil sharpener assembly in Fusion 360, consisting of over 20 interacting components, including gears, shafts, cutting geometry, housings, and fasteners. The project emphasized spatial organization, component alignment, and realistic assembly constraints within a compact consumer-scale form factor.
Sectioned views and exploded assemblies were used to validate motion paths, gear engagement, and internal clearances. The primary challenge was maintaining functional alignment and manufacturable geometry while integrating a dense mechanical drivetrain into a constrained enclosure.

Parametric Automation via Spreadsheet-Driven Parameters
Created a fully parametric assembly in Siemens NX using a single base model and an Excel-driven parameter table to automatically generate 45 distinct part variants with differing dimensions and configurations.
The project emphasized associative modeling, configuration control, and scalable CAD workflows, demonstrating how spreadsheet-linked parameters can efficiently manage part families while maintaining consistent interfaces and assembly constraints.
