CAAT is a cat litter box concept with an embedded mechanism capable of filtering and disposing of dirty sand directly into a garbage bag.

The design process followed 4 principles:

(1) Discrete and neutral design

(2) Easy upkeep

(3) Simple and intuitive mechanism

(4) Capable of either filtering or disposing of the dirty litter directly into a garbage bag

Pushed position (left) -> Lever coupled to the comb like shovel - litter filtering mode

Middle position (middle) -> Locked mechanism for safe cat use

Pulled position (right) -> Lever  coupled to the false floor - litter disposing mode

The base is composed by the support (left) and litter platform (right).

-> When the shovel is activated, it pushes solid bodies wider than 16mm towards the ramps located on the front of the platform. They then fall into the dark drawer which the user can use to dispose of the separated contents into the garbage.

-> The ramps can be easily removed in order two access to garbage bag storage spaces for maintenance convenience.

-> When the false floor is activated a gap below the litter floor opens and dirty litter falls into a pre placed bag below. By selecting the disposing mode, the shovel is released, and with the force of gravity, it assists in pushing the litter into the middle opening.

-> The geometry of the support is optimized to prevent unwanted buildup of litter in the middle of the bag.

This product was designed to withstand cats weighting up to 10 kg.

Displacements during working conditions were also evaluated in order to specify appropriate geometrical tolerances.
