We research the possibilities for an interactive wall. The conventional inner wall divides room in a static way. This static wall has some weaknesses which we can solve by making it interactive. These are the most important spatial developtments the interactive wall can make possible.
- Spatial efficiency by Multi use of space; when we are in one room, we would like this room to be bigger. When we are in the other room, we want that other room to be bigger. An interactive wall could follow your movement and enlarge the room which you are currently using. Space is not statically connected to a room and a function, but it will follow the user.
- Spatial efficiency by integrated furniture; we don’t use the furniture all the time. If we don’t use the furniture, it normally still takes in precious space. We can prevent this by making the furniture integrated in the wall, allowing the furniture’s to arise only when needed.
- Spatial connection by integrated door; usually the wall is interrupted by a door, to make connection between different rooms possible. An interactive wall could make doors unnecessary by integrating it.
So we can define our concept as a moving interactive wall that makes multifunctional space, furniture and integrated doors possible.
A wall is big and our requirements ask for a lot of movements. We have to make this movement with a very limited amount of motors. So the trick is to find a method that passes on a single movement through out the whole wall. We found different methods for this:
- Scissor lift; a scissor lift is a mechanism in which the whole geometry follows the movements of a single element. The wall could be made by a scissor lift made by sheets. If we take two walls, and make it possible for each wall to make it rotate from the wall, and inside, it allows us to meet the 3 requirements. More layers of this scissor lifts could be stacked on top of each other to make a variety of movements possible in the wall. We didn’t continue with this method because every scissor lift still needs 3 motors, and stacking them would be very difficult regarding the weight it will have.
- Rhombuses and strings: We made a net of horizontal rhombuses, which could be moved by strings. However, when we made a test we discovered that because of the lack of rigidness in the geometry of the rhombuses, we need a lot of strings to create a geometry.
Layered wall (our final soluation)
To fix the problem of gravity we made a layered wall. A simple tube inside the wall will create shapes, like the principle of a pinwall. The wall will follow the shape of the tube. The 1:20 mock-up we made is a versy simple example of this method. The shape of the tube is fixed and we just rotate it, so we can only make a few shapes. We think it has a lot of potential if we later develop it with a tube that can change shape or something similar.
To develop this we didn’t need a complicated model in grasshopper, because all the sheets have the same rectangular shape, only the shape of the tube is important. We printed some sheets and tested different shapes of tubes.
There are some critical things to keep in mind: • There are different configurations in tubes. 1 straight tube and 1 bended tube makes a double curved wall, but it also makes it expand in the longitudinal direction which is unwanted. Two equally bended tubes makes only a single curved wall, and makes all the sheets move only in 1 direction (X+ en X-). We chose for the double curved now, but you can see we had to cheat in the fixed walls. • We can’t make it horizontal, but we can make a very low slope by making a thin tube and thin sheets • In this case we can only bend the tube in 1 X-direction, if else the two walls will clash
A light sensor detects the presence of a user in a room. To make it easy we just use one sensor. Sometimes the wall needs to make a door, sometimes it needs to make a seat. We distinct this functions with a button.
The motors are in the floor, connected to the tubes.
