In the beginning we dealt with possible principles for creating a weighing surface on the wall, as the core task of the project required. We quickly focused on the idea of an extendable surface which, similar to a blind, can be stored in a space-saving roll when not in use.
The core element of our kitchen scales is the self-reinforcing weighing surface, which consists of individual chain links. In combination, the links block each other in only one direction, so that the weighing surface can still be rolled up. We experimented a lot with different laser-cut and 3D-printing variants and decided to use a step link made of plexiglass in our final prototype.
The chain link fabric  forms a unit with the roller blind housing , which is weighed as a whole on the support . In order to avoid falsification of the values due to different torques, rotation is prevented by guide pins  on the underside and thin sheet metal plates  between the bracket and the roller.
MAKI convinces with clear interaction gestures, which are particularly helpful in the kitchen working environment. In contrast to a touch display or small buttons, the large tare button on the right-hand side can also be easily operated with hands soiled by cooking. The large but narrow unit ring is easy to adjust and in the event of a dirty weighing surface, it can be easily removed through the service access on the left and placed in the dishwasher.
