The project was created as a result of a daily problem in interior design: the width of the shutter box was larger than the thickness of the wall. As a result, the box extended out from the wall, preventing clean design lines.

​

As with any roller shutter, the size of the box is determined by the shutter diameter in its closed state. The objective of the project was to reduce the diameter of the scrolled shutter as much as possible, enabling it to fit entirely inside the wall.

​

The input given to us was a single shutter louver and the parameters for change, such as the hook height, width of the louver, etc. In addition, we also had the option to change the radius of the cylinder on which the louvers scroll.

It seems to be a simple task, but the manner in which the louvers were setting while they were scrolling, and the manner in which they were interlocking, required a different approach.

​

After attempting to work with existing physical models in order to solve the problem without success, we decided to write a specific solver that would ensure that the louvers would correctly roll over each other. Then we connected the solver to an optimization component (Opossum using rbfopt) until the desired output was achieved.

​

Eventually, the width of the shutter was reduced by about 20% of its original size, which allowed the box to fit securely into the wall.
