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
Designed and validated mechanism components for Aqua using Rhino 3D, including simulation and optimization of key mechanical systems.
Experiment
Robot Hand, Rotational motion to linear motion 1
Iris mechanism, Rotational motion to linear motion 2
Cylinder mechanism + Rotation angle variation using crown gear
Generate two-axis linear motion using rotational motion
Planetary gear system to create individual rotational effect
Rachet system, One-directional rotational movement
Bat wing design, Rotational motion to generate 3-axis movement
Wing angle control design, Bevel gear + planetary gear combination
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.
