Existing lock interface
The mechanism had to couple to installed hardware and real door clearances.
ResponseDeveloped an add-on enclosure and circular coupling around the existing lock geometry.

01 / Project overview
Integrate an electromechanical system with existing hardware.
The prototype mounts below a real door handle and operates the installed lock through a printed mechanism, enclosure, actuator, wiring and control electronics. The available archive identifies the work as a collaboration between Yiming and Paarth.

02 / Design challenge
Fit a moving system into a constrained add-on product.
The prototype had to work with an existing lock rather than replace the door hardware, while keeping moving parts, electronics and wiring within a narrow mounted enclosure.
Competing internal volumes
Movement, electronics and wiring compete for limited space.
ResponseSeparated the housing into printable parts and reserved an internal cavity for integration.
03 / Engineering approach
Design the mechanical and electrical layers as one system.
The project packages the lock interface, actuator, mount, control components and wiring around the geometry of the real door.
Measure the host
Work around the door, handle rose, lock position and available clearances.
Package the mechanism
Create a multi-part enclosure, circular interface and actuator mount.
Integrate electronics
Route wiring and place control components inside the mechanical housing.
Test on the door
Mount the complete assembly and record it in the intended environment.
Prototype development
Mechanical packaging made visible.
Testing & integration
Validate the prototype in its real operating context.
The final evidence shows the assembled system mounted beneath the door handle with the electrical and mechanical layers operating together.
Shared project scope
- Package an actuator, wiring, electronics and moving lock interface.
- Develop and print components around existing handle and lock geometry.
- Assemble the electromechanical system and validate it on the real door.
Collaboration statement
This project was completed by Yiming Aizezi and Paarth. The archive contains no task-allocation record, so mechanical design, electronics, integration and testing are credited to the team. No subsystem is claimed here as Yiming’s work alone.
06 / Outcome
A functional door-mounted mechatronics prototype.
The result integrates printed mechanics and exposed electronics within one enclosure and demonstrates the complete system on the real door.
