Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing animal litter composed of bentonite clumps form too slowly, are prone to disintegration when scratched by animals, and require excessive effort to discard, especially in automatic litter boxes.
Innovation Solution
Animal litter comprising 80% by mass of granular matters with a grain size of 0.5 mm to 1.5 mm, achieving a clump strength of 8.0 N or more within 1 minute after absorbing 20 ml of saline solution, with enhanced capillary action and adhesion properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If granular matters mainly composed of bentonite are used as animal litter, then urine absorption capability is improved, but clump formation time increases and strength is insufficient at early stages
Solution Approach 1:
The patent changes the grain size parameter of bentonite granular matters to a specific range (0.8 mm to 2.0 mm) to optimize both urine absorption speed and clump formation characteristics. This parameter optimization enables the litter to achieve sufficient clump strength in a shorter time while maintaining effective urine absorption capability.
Solution Approach 2:
The patent uses bentonite as the primary material which possesses both high urine absorption capability and clumping properties. By selecting and processing this specific material with controlled grain size, the invention achieves a balance between rapid urine absorption and timely clump formation without requiring complex composite formulations.
2Quantity of substance
If granular matters are not sufficiently bound, then urine absorption is maintained, but clump strength decreases and disintegration occurs when scratched by animals
Solution Approach 1:
The patent optimizes the grain size parameter of bentonite to a specific range (0.8 mm to 2.0 mm) which enhances both the binding capability and urine absorption. This parameter control ensures that granular matters form strong clumps that resist animal scratching while maintaining effective urine absorption, eliminating the need for additional binding agents.
3Volume of stationary object
If small-diameter granular matters are used, then clump volume is reduced for easier disposal, but scattering resistance when scratched by animals decreases
Solution Approach 1:
The patent selects a specific grain size range (0.8 mm to 2.0 mm) that optimizes the balance between clump volume and scattering resistance. This parameter optimization ensures that clumps remain compact and manageable for disposal while being sufficiently resistant to scattering when animals scratch the litter, without requiring additional stabilizing components.
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 litter quickly forms firm, small clumps that resist disintegration, maintaining litter box hygiene and reducing disposal effort, suitable for automatic litter boxes.
Implementation Method 1
Granular matters mainly composed of bentonite absorb excreted urine, swell, and mutually adhere to form a clump
Data Source
AI summary
Provided is animal litter, wherein granular matters can adequately absorb urine, and wherein the granular matters can form small clumps having high strength at an early stage. Animal litter includes granular matters mainly composed of bentonite. The granular matters include 80% by mass or more of the granular matters having a grain size of 0.5 mm or more and 1.5 or less. Clump strength of a clump of the granular matters after 1 minute has elapsed since addition of 20 ml of a 0.9% by mass saline solution to the animal litter is 8.0 N or more.
