Advances in architectural geometry and mechanical simulation have revealed a new kind of spatial mechanism that can be constructed from straight elastic lamellas connected through scissor joints. These lamella grids can be easily manufactured and offer a controlled movement from a flat shape into a doubly curved shape. This has the potential to inform the design of transformable structures at all scales from foldable roofs and adaptive building facades to medical stents for heart surgery.

We use computational tools to design a grid along so-called asymptotic curve on surfaces with negative Gaussian curvature. We adjust its kinetic behaviour by controlling the element stiffness, joint rotation and support conditions. Through physical prototypes, we investigate various design possibilities and actuation techniques. The Kinetic Umbrella, our first large-scale architectural application, has just been completed in Munich.

The interactive exhibition introduces our research through experimental models and simulations and shows full-scale documentation of the Kinetic Umbrella.
