Aqua

Mechanism Experiment Project
2 Weeks
Tools
Rhino 3D, Laser cutting, 3D printing, Handcrafting
Project Overview
Aqua is a musical instrument born from effectively applying the mechanisms we developed in the Mechanism project. The beautiful sound of metal balls striking the glass tubes creates a magical effect, resulting from the combination of a complex mechanism and a simple method of operation.
My Contributions
I played a crucial role in the project by utilizing Rhino 3D to design intricate mechanism parts, overseeing simulations, and validating optimal mechanisms for Aqua.

Rotational motions into multiple vertical motions to generate a sine wave

Mechanism research

I created various motions using rotational motion, which is the fundamental movement of all motions. Through this process, I explored ways to transform a single movement into diverse outcomes, allowing me to develop the complex mechanical structure of Aqua.
digitization

Custom measurement tool

Variations between CAD dimensions and actual laser-machined parts can result in poor tolerances and faulty assembly. To mitigate this, a laser-cut measurement module was developed, enabling precise dimensional checks and reducing design errors.
Crafting

Design for manufacturing

Parts were standardized to use the same material and process, reducing packaging size. Unifying component heights as much as possible improved productivity and minimized the overall footprint.

Revolutionary design transformation

A novel device was developed by adapting the mechanism of radial engines to operate with an off-center rotational axis. This configuration allowed the marble-lifting unit (right image) to be positioned at the center.

Design optimized for assembly

Using a custom measurement tool, components were aligned and assembled within tight tolerances, ensuring a highly accurate and reliable build.
