Redwood Wave This video show the use of wooden planks on rollers that create varying patterns that mimic a wave when the rollers are turned. We loved this movement and wanted to create a similar affect on a wall system.

LIGO Wave Wall The LIGO Wave Wall is an exterior shading system that moves with the wind. This gave us a good idea of how to construct the wave as a
CONCEPT: Our concept was creating a moving wave using materials that are not generally associated with waves. To create a dynamic, fluid movement that moves in a set pattern to give an illusion of moving water.
wall, by having a single central axis as a connection point for all the members.

DIGITAL MODELLING For the digital 3D model, we focused on the movement of the members with respect to the two established axis. The first axis is the pivot point of the members which runs horizontally at the midpoint. The second axis is the crank shaft system that will be connected to each member by rods, creating the wave movement.

PHYSICAL MODELS
After drawing up a 3D digital model we pro-
ceeded to quickly build physical representations.
The first was constructed from cardboard with a dowel through the center of each member, and a bent piece of wire for the crank shaft system. After creating the first model, we built another model that would better represent the idea, using MDF for material, which also gave it rigidity and durability. We continued to play with the crank shaft design at this point, trying to figure out what sort of system would yield the results we were aiming towards.

CRANK SHAFT PROCESS Linear design: This version of the crank shaft
gave the wall movement but not in the fluid manner that was desired.
Each member was always a
set distance away from the one next to it which gave a stagnant effect.
Radial design: The change from linear to radial gave the desired movement when connected to the wall.
Each member travelled the same dis-
tance around the central axis point of the shaft, rather than being dependant on the member on either side.
Radial design: A plan view of the radial crank shaft shows the amplitude and movement of the wave. This is the first time that we knew that the
new design would be able to facilitate the move ment we were aiming for.
Gearing System: After finalizing the design of the crank shaft, we started to think of how we would turn it in a built environment. The shaft itself would not be strong enough to provide the amount of torque needed, so a separated gearing system would need to be developed in order to drive the system.
