Conducted a complete mechanical system teardown and analysis of a manually operated sewing machine to understand its internal components, assemblies, and motion transmission mechanisms. The project involved disassembling the system to examine gear trains, motion control mechanisms, linkages, shafts, bearings, and tolerance relationships, with a focus on how rotational input is converted into coordinated needle and feed motion.

​

​Following the teardown, the system was fully reconstructed as a detailed three-dimensional Computer-Aided Design model in SolidWorks, accurately representing component geometry, assembly constraints, and motion relationships. The rebuild required precise modelling of interacting moving parts and kinematic linkages, reinforcing practical understanding of mechanical systems, motion conversion, and assembly hierarchy.

​

​This project strengthened skills in mechanical systems analysis, reverse engineering and kinematic mechanism evaluation, while developing strong proficiency in SolidWorks assembly modelling.
