Cat Toilet With Inclined Classifying Part for Waste Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cat litter boxes mix cat feces and urine, making them difficult to clean and requiring frequent maintenance, and are costly due to high litter consumption.
Innovation Solution
A cat toilet with a supporting surface, inclined classifying part, and separate storage containers for feces and urine, allowing for the separation and storage of feces and urine without litter, reducing cleaning frequency and litter costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional litter box is used to allow cat's defecation and urination, then the cat can eliminate waste, but the excreta (feces and urine) mix together making it difficult to dispose of and requiring frequent cleaning
Solution Approach 1:
The device divides the waste collection area into two separate compartments: an upper compartment for feces and a lower compartment for urine. This segmentation allows feces and urine to be collected separately, making disposal easier and more hygienic. The upper compartment has a through hole that allows urine to pass through to the lower compartment while feces remain in the upper compartment.
2Loss of substance
If a litter box with cat litter is used, then cat excreta can be absorbed and buried, but the litter consumption is great and costs a lot in a prolonged period
Solution Approach 1:
The invention extracts the litter material from the system entirely. Instead of using cat litter to absorb and bury waste, the device uses a structural separation system where feces and urine are collected in separate compartments. This eliminates the need for consumable litter material while maintaining effective waste management.
3Reliability
If the litter box is cleaned frequently to maintain hygiene, then the environment remains clean, but the time and effort required for maintenance increases
Solution Approach 1:
By segmenting the waste collection into separate compartments for feces and urine, the device enables selective cleaning. Owners can remove and clean only the feces compartment or the urine compartment independently, rather than having to clean the entire box at once. This reduces the time and effort required for maintenance while maintaining hygiene.
4Device complexity
If a simple litter box structure is used, then the device is easy to manufacture, but it cannot separate feces and urine effectively
Solution Approach 1:
The device implements a two-compartment structure with a through hole in the upper compartment. This segmentation design is relatively simple to manufacture while effectively separating feces (retained in upper compartment) from urine (passing through to lower compartment). The simplicity of the structure is maintained while achieving effective waste separation.
Solution Approach 2:
The invention adds a vertical dimension to waste separation by placing the feces collection compartment above the urine collection compartment. Urine falls vertically through the through hole in the upper compartment to the lower compartment, while feces remain in the upper compartment. This vertical arrangement achieves effective separation with minimal structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively separates and stores cat feces and urine, keeping them dry and reducing the need for frequent cleaning, while minimizing litter usage and environmental impact.
Implementation Method 1
The sloped surface is exposed through the egestion opening for guiding the feces, so that the feces moves along sloped surface to the first entrance and enter the feces storage container through the first entrance
Implementation Method 2
The urine storage container is disposed below the sloped surface for storing the urine flowed from the through hole

AI summary
A toilet for separating excreta of a cat into feces and urine includes a supporting part, a feces storage container, an inclined classifying part, and a urine storage container. The supporting part has a supporting surface and an egestion opening formed on the supporting surface. The feces storage container is disposed below the supporting surface, and has a first entrance. The inclined classifying part has a sloped surface and through holes formed on the sloped surface. The egestion opening allows the sloped surface to be exposed for guiding the feces, so as to move the feces along the sloped surface to the first entrance, and allow the feces to enter the feces storage container from the first entrance. The urine storage container is disposed below the sloped surface for receiving urine flowed from the through holes.
