Next Generation Self Powered Hotel Door Lock System (still in development)

I contributed to the development of an innovative self powered hotel door lock designed to eliminate the need for traditional battery replacements. Hotels spend significant time and money replacing lock batteries every few months across hundreds of rooms. This product introduces a long term solution: a lock system capable of operating for its entire service life without ever requiring a battery swap.

Working in SolidWorks, I created a detailed mechanical model of the lock’s internal components, focusing on precision geometry, manufacturability, and part integration. The design incorporates a multi piece assembly including a custom rotating actuator, a spherical cam interface, a mounting plate, and an energy transfer shaft. These components work together to convert user interaction into stored, usable power. My modeling work included exploded views, engineering drawings, tolerancing consideration, and early stage motion analysis to verify fit and alignment.

The system utilizes a novel internal power source that harvests mechanical energy from lock operation. Every time the user engages the handle or actuator, the mechanism generates and stores energy, making the system effectively self sustaining. This removes a major maintenance burden for hotels, improves reliability, and lowers long term operating costs. The lock is engineered to be backward compatible with existing hotel door hardware, streamlining installation across large facilities.

My role blended mechanical engineering, industrial design considerations, and systems level analysis to help transition the concept toward a manufacturable product. I supported design iteration, assembly refinement, and component optimization while collaborating with the engineering team to evaluate structural behavior, tolerance stack up, and real world usability.

This project demonstrates my ability to work on innovative consumer grade hardware, create production ready CAD models, and apply systems engineering principles to solve high impact industry problems.
