Multi-Layer Rabbit Litter Box Structure to Contain Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional rabbit litter boxes using wood or shredded paper result in unhealthy living conditions due to rabbits sitting in their waste, generate significant waste, are expensive to maintain, and cause litter to be kicked out into the household.
Innovation Solution
A multi-layered animal litter box system comprising an upper layer made of semi-rigid material with holes, a flexible middle layer, and a rigid bottom layer, designed to contain waste and prevent litter from spreading, combined with a feeder system that minimizes mess.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional litter boxes use wood or shredded paper, then rabbits have a litter box to use, but rabbits sit in their waste creating unhealthy conditions
Solution Approach 1:
The litter box is divided into multiple layers: an upper layer for rabbit activity, a middle absorbent layer for waste absorption, and a lower tray for collection. This segmentation separates the rabbit's living space from the waste, preventing direct contact and improving health conditions.
Solution Approach 2:
An absorbent middle layer acts as an intermediary between the rabbit and the waste collection tray. This layer absorbs urine and feces, preventing the rabbit from sitting in waste while allowing waste to be contained and removed separately.
2Quantity of substance
If traditional litter boxes use wood or shredded paper, then rabbits have litter to use, but significant waste is generated
Solution Approach 1:
The design allows the absorbent middle layer and lower tray to be removed and emptied separately from the upper layer. Used litter material in the lower tray can be discarded while the upper layer remains intact for reuse, reducing overall waste generation.
Solution Approach 2:
The absorbent layer changes its absorption capacity over time, allowing it to be used until saturated. This extends the functional life of the litter material before disposal is needed, reducing frequency of waste generation.
3Quantity of substance
If traditional litter boxes use wood or shredded paper, then rabbits have litter to use, but maintenance costs are high
Solution Approach 1:
The segmented design allows selective replacement of only the absorbent layer and tray when soiled, while the upper layer and box structure can be reused. This reduces the frequency and cost of complete litter box replacements.
Solution Approach 2:
Reusable components (upper layer, box structure) are separated from disposable components (absorbent layer, tray). This allows recovery and repeated use of expensive structural elements while discarding only the consumable litter materials.
4Ease of operation
If traditional litter boxes use wood or shredded paper, then rabbits have litter to use, but litter is kicked out into the household
Solution Approach 1:
The upper layer has asymmetric edge heights, with higher sides on three sides and a lower fourth side forming a spillway. This asymmetric design guides rabbit movement and litter containment, allowing controlled litter distribution while preventing scattering into the household.
Solution Approach 2:
The spillway design uses a dimensional approach by creating a sloped surface that directs litter and waste toward a designated exit point rather than allowing random scattering in multiple directions.

AI summary
An animal litter box and feeder are disclosed. Animals, such as rabbits, typically have an animal litter box and an animal feeder. The litter box disclosed is a multi-layer structure including a lower layer, at least one middle layer, and an upper layer. The lower layer is more rigid than one or both of the upper layer and the at least one middle layer, and composed of different materials than one or both of the upper layer and the at least one middle layer. For example, the lower layer may be rigid and composed of hard plastic, the upper layer may be semi-rigid and composed of paper, and the at least one middle layer may be non-rigid and composed of plastic. The multi-layer configuration for the animal litter box may be used in combination with an animal feeder in order to provide a combination animal litter box and feeder.
