SUT · Reverse Engineering of a Can Opener

Conducted a complete reverse engineering and redesign study of a consumer can opener, reconstructing all component geometries, material specifications, functional tolerances, and assembly relationships from a physical product — without access to original design documentation. The project followed a systematic teardown-to-documentation workflow standard in industrial practice for legacy part reconstruction, competitive benchmarking, and design-for-manufacturability analysis.

Each component was dimensioned using precision measurement instruments and modeled in CAD, with particular attention to functional surfaces, mating geometries, and kinematic pairs. GD&T (Geometric Dimensioning and Tolerancing) was applied throughout the technical drawing set, defining form, orientation, and location tolerances that ensure assembly interchangeability and functional performance within the mechanism's kinematic chain. Blueprint standards and manufacturing notes were documented to support downstream machining and quality inspection processes.

The final deliverable comprised a complete engineering drawing package — part drawings, assembly drawing, exploded view, and bill of materials — meeting professional drafting standards. The project demonstrated end-to-end design documentation competency across the full reverse engineering pipeline: measurement, CAD reconstruction, tolerance analysis, GD&T specification, and manufacturing feasibility assessment.
