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.

Constraint 01

Existing lock interface

The mechanism had to couple to installed hardware and real door clearances.

Response

Developed an add-on enclosure and circular coupling around the existing lock geometry.

Constraint 02

Competing internal volumes

Movement, electronics and wiring compete for limited space.

Response

Separated 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.

01

Measure the host

Work around the door, handle rose, lock position and available clearances.

02

Package the mechanism

Create a multi-part enclosure, circular interface and actuator mount.

03

Integrate electronics

Route wiring and place control components inside the mechanical housing.

04

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.
