Density-Graded Animal Litter Composition for Clumping and Odor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Natural animal litters lack desirable organoleptic properties and clumping strength, with wood-based litters having poor clumping when wetted and grain-based litters lacking appealing appearance and aroma.
Innovation Solution
A composition comprising a first component with a density less than that of a liquid and a second component with a density at least 5 lb/ft3 greater, causing segregation when a liquid is added, resulting in the first component floating and the second component absorbing the liquid, thus enhancing appearance, aroma, and clumping properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wood-based litters are used, then desirable organoleptic properties (appearance and aroma) are achieved, but clumping strength when wetted is poor
Solution Approach 1:
The patent combines wood-based litter material (providing organoleptic properties) with clay or clay-like material (providing clumping strength) to create a composite litter that achieves both desirable appearance/aroma and strong clumping when wetted
Solution Approach 2:
The patent uses composite materials consisting of wood particles combined with clay or clay-like particles, where each material contributes its superior properties to the overall litter performance
2Strength
If grain-based litters are used, then strong clumping is achieved, but organoleptic properties (appearance and aroma) are poor
Solution Approach 1:
The patent combines grain-based litter material (providing clumping strength) with wood-based material (providing organoleptic properties) to create a composite litter that achieves both strong clumping and desirable appearance/aroma
Solution Approach 2:
The patent uses composite materials consisting of grain particles combined with wood particles, where each material contributes its superior properties to the overall litter performance
3Object-affected harmful factors
If natural litters are used, then biodegradability and low dust are achieved, but clumping strength and odor control are poor
Solution Approach 1:
The patent uses composite materials combining natural biodegradable components with clay or clay-like materials to maintain biodegradability while adding clumping strength and odor control capabilities
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 composition provides a more appealing appearance and aroma while forming strong, firm clumps, effectively managing animal waste by segregating unpleasant odors and appearances, improving user interaction with the litter.
Implementation Method 1
a first component having a density less than that of a liquid and a second component having a density of at least 5 lb/ft3 (80 mg/cm3) greater than the first component. When a liquid is added to the composition, the two components segregate
Implementation Method 2
the more dense second component absorbs the liquid at a greater rate than the first component

AI summary
The invention provides a composition suitable for use as an animal litter comprising a first component having a density less than that of liquid and a second component having a density of at least 5 lb/ft3 (80 mg/cm3) greater than the first component. The invention is based upon the discovery that adding liquid such as urine to a composition having two components with significant differences in density, one of which is less than the density of the liquid, will result in the component with the lesser density floating to the top of the liquid while the component with the greater density will segregate below the component with the lesser density.
