Abstract

Novel tools and techniques are described for a passive suction base. In one aspect, a passive suction base can be provided on a bottom of an item for adhering the item to a flat surface. The passive suction base might comprise a central portion affixed to the bottom of the item and a perimeter portion that is not affixed to the item. A force opposing the flat surface when applied to the item causes the central portion to move away from the flat surface, while the perimeter portion remains in contact with the flat surface, thereby causing the passive suction base to adhere to the flat surface. In some aspects, when resting on the flat surface, the perimeter portion of the suction base can be substantially flat with respect to the flat surface (and not visible), so that the passive suction base may be easily moved along the flat surface.
