Solution Overview

Problem

Existing litters for animal husbandry lack high clumping strength, cause excessive sticking to animal hair, and have inadequate odor-binding properties, leading to inefficient waste management and contamination.

Innovation Solution

A litter composed of 65-99.5% cereal flour, 0.1-20% gelling agents (such as guar gum), and 0.01-15% odor reducers (like calcium chloride or citric acid) in the form of pressed granules, which enhances clumping strength, reduces stickiness, and improves odor binding by forming a three-dimensional structure that traps odors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wood flour and gelling agents are used as bedding material, then liquid absorption and clumping are improved, but adhesion to animal hair increases and odor binding is insufficient

Engineering Contradiction:
Improveclumping performanceVSAvoidadhesion to animal hair and odor
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by replacing wood flour with cereal flour (wheat, rye, barley, corn, rice, or millet flour) and optimizing the gelling agent content to 1-10% by weight. This parameter change modifies the surface properties and molecular structure of the bedding material, reducing adhesion to animal hair while maintaining clumping performance through the specific starch composition of cereal flour.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite material system combining cereal flour with specific gelling agents (guar gum, locust bean gum, tara gum, xanthan gum, gellan gum, karaya gum, alginate, agar, carrageenan, gum arabic, pectin, tragacanth, or cellulose ethers) and odor-reducing agents (chlorides or acids). This composite approach leverages the synergistic effects of each component: cereal flour provides clumping base, gelling agents enhance moisture binding, and odor reducers neutralize unpleasant smells, achieving multiple functions simultaneously.

Inventive Principle:
Principle #40Composite materials

2Strength

If cereal flour with high starch content is used, then clump strength is improved, but manufacturing complexity increases due to processing requirements

Engineering Contradiction:
Improveclump strengthVSAvoidmanufacturing process complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-gelatinizing the cereal flour through extrusion or chemical treatment before final product formation. This pre-processing step modifies the starch structure in advance, creating a material that requires minimal additional processing during bedding manufacturing. The pre-gelatinized flour can be directly mixed with gelling agents and odor reducers, significantly simplifying the overall manufacturing process while ensuring high clump strength.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the physical state parameter of the cereal flour by converting it from raw starch to pre-gelatinized starch through extrusion or chemical treatment. This parameter change transforms the material properties, making it more receptive to binding agents and enabling direct use in bedding formulation without complex cooking or gelatinization steps during manufacturing, thus reducing device complexity.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If pre-gelatinized flour is used to increase water-binding capacity, then moisture absorption is improved, but production cost increases due to extrusion or chemical treatment

Engineering Contradiction:
Improvewater-binding capacityVSAvoidproduction cost
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The patent offers a parameter change option by providing both raw cereal flour and pre-gelatinized cereal flour as alternatives. Users can select raw cereal flour for cost-sensitive applications where simple mixing suffices, or pre-gelatinized cereal flour for performance-critical applications requiring superior water-binding capacity. This flexible parameter approach allows optimization based on specific application requirements and budget constraints.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies partial action by offering pre-gelatinization as an optional enhancement rather than a mandatory step. The bedding formulation works effectively with both pre-gelatinized and raw cereal flour, allowing manufacturers to apply the more expensive pre-gelatinization treatment only to the extent necessary to meet performance specifications, rather than universally applying it to all production batches.

Inventive Principle:
Principle #16Partial or excessive action

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 effectively forms clumps that can be easily removed, minimizing contamination and odor release, with enhanced moisture retention and absorption, reducing the need for frequent replacements and maintaining a clean environment.

Implementation Method 1

gelling agents serve as liquid absorbers and clump preventers

Methodology Applied
