Product Design & UX
The objective of this project was to design an interactive object that changes from solid to void when triggered by touch.
Hypothesis
Through the application of custom components and joint-based assembly systems, can an object transform from solid to void?
An object can take on a completely new form when the members that make up that object inflate.
Solution
A kit-of-parts is designed to make up a system of pipes and joints (like a lego set). Thin pipes are wrapped in silicone tubes and inflated and deflated in order to change the object's visual density.
Process
This project began with a series of form-finding exercises that started with a simple cube. Parametric modeling allowed for many fast, iterative variations.
Transformation Results
The resultant form retains characteristics of its original form - the cube, along with elements like the structural pipework.
A 3D printed node connects each pipe member.
Joint Based Assembly
Custom hollow nodes act as the structural glue that links the pipework together.
A mock-up model that tested node to pipe ratios determined the best overall joint sizes for the inflatable structural members

Details
A silicone casted sleeve is slipped over the structural tubes which connect to a hollow joint. Air is then pumped into the structure to inflate the silicone.

Testing and Activating
The final installation is activated by an observer's hand. It was important that the user intuitively know how to activate the model without being told how to activate it.
A copper plate located on the podium acts as the conductor for activating the inflatable tubes. When the copper plate is touched it sends a signal to the Arduino processor which then triggers the inflation actuator. This sends air through the hollow tubes towards the tubes wrapped in elastic silicone.
