Feline Litter Box Sieve System with Suspended Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feline litter box sieves are inefficient in removing clumped litter and feces, often ripping the liner and breaking clumps, leading to incomplete removal and a tedious process.
Innovation Solution
A litter sieve assembly that suspends a litter box over a trash receptacle, using a support frame and pivoting lid with a screen top to separate clumped litter and feces from unclumped litter, allowing the former to be discarded while the latter is reused.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a handheld sieve with perforated scoop is used to remove clumps, then clumped litter and excrement can be removed, but the liner is ripped and clumps are broken into small pieces that remain in the box
Solution Approach 1:
The device divides the litter box into two compartments: a clean litter receptacle and a soiled litter receptacle, allowing separation of clean and soiled litter without physical contact that would damage the liner or break clumps
Solution Approach 2:
The soiled litter is extracted from the clean litter through a partition wall with openings, allowing clumps to be removed intact through the openings while the liner remains undisturbed in the clean compartment
2Reliability
If manual scooping is used to remove clumps, then clumped litter can be removed, but the process is time consuming and tedious
Solution Approach 1:
The device is installed beforehand in the litter box, creating a ready-to-use separation system that eliminates the need for manual scooping and allows for quick disposal of soiled litter
Solution Approach 2:
The cat itself performs the separation function by depositing waste in the soiled litter compartment, eliminating the need for human intervention in the clump removal process
3Loss of substance
If clumps are broken into small pieces during removal, then some litter can be salvaged, but urine soaked clumps remain in the box
Solution Approach 1:
The partition wall with openings extracts soiled litter from the clean litter, ensuring complete removal of urine-soaked clumps while preserving the clean litter for reuse
Solution Approach 2:
The device creates different functional zones: the clean litter compartment maintains litter quality for reuse, while the soiled litter compartment collects and isolates contaminated material for disposal
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
Facilitates quick and reliable separation of clumped litter and feces from unclumped litter, reducing odors and maintenance time, and allowing for the reuse of clean litter.
Implementation Method 1
The lid includes a screen top with apertures. The apertures of the screen top are sized to prevent passage of feline feces and clumped litter.

AI summary
A feline litter box sieve system includes a screened lid connected by a hinge to a support frame that suspends an empty litter box in the top opening of a trash receptacle. L-shaped hooks suspend the support frame in the trash receptacle. Used litter is poured from a full litter box onto the screen. Clumps and feces are retained by the screen. Pivoting the lid to an open position dumps retained clumps and feces from the screen into the trash receptacle. While the lid is open, the held litter box containing unclumped sifted litter may be removed for use.
