Solution Overview

Problem

The shortage of guar gum and other gums used in clumping agents for animal litter has led to inefficiencies in clump durability and water absorption, and existing alternatives like starches and celluloses do not meet the requirements for high clump strength and water absorption capacity, posing challenges in waste management and odor control.

Innovation Solution

A litter composition that includes a particulate water-absorbing carrier, two solid particles reacting to generate molecular iodine, and a solid acid system to maintain a pH between 3.5 and 7.5, along with a clumping agent comprising pre-gelatinized starch and borax, bicarbonate, or aluminate, and carboxymethyl cellulose, which provides enhanced clump durability and antimicrobial activity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If guar gum is used as a clumping agent, then clump durability is improved (at least 95%), but supply shortage occurs due to high demand from oil and natural gas industries

Engineering Contradiction:
Improveclump durabilityVSAvoidavailability of guar gum
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The patent replaces expensive, scarce guar gum with cheaper, more readily available alternative materials such as starches and celluloses. While these alternatives may not achieve the exact same clump durability as guar gum, they provide sufficient performance for the application and are much more abundant in the market, eliminating the supply shortage problem.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent combines multiple alternative materials (starches, celluloses, and other polymers) in specific compositions to achieve clump durability comparable to guar gum. By creating composite clumping agent systems rather than relying on a single material, the patent maintains high performance while using readily available components.

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If starches and celluloses are used as alternatives to guar gum, then availability is improved, but clump strength and water absorption capacity are insufficient

Engineering Contradiction:
Improveavailability of clumping agentsVSAvoidclump strength and water absorption capacity
Core Design Contradiction:
Quantity of substanceVSStrength

Solution Approach 1:

The patent modifies the physical and chemical parameters of starch and cellulose materials through processing techniques such as pre-gelatinization, oxidation, or cross-linking. These parameter changes enhance the water absorption capacity and clumping performance of the alternative materials, bringing them closer to the performance level of guar gum while maintaining availability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies different treatments or modifications to specific regions or aspects of the clumping agent materials. For example, certain functional groups on starch or cellulose molecules are selectively modified to enhance water interaction, while other regions maintain structural integrity for clump formation. This localized optimization improves overall performance.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If multiple additives are added to litter, then functional benefits are improved, but cost increases and product complexity increases

Engineering Contradiction:
Improvefunctional benefits of litterVSAvoidnumber of additives
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs clumping agents and litter components that perform multiple functions simultaneously. For example, the clumping agent not only forms clumps but also provides odor control, water absorption, and potentially antimicrobial properties. This multi-functionality reduces the need for separate additives for each function, simplifying the overall product formulation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines multiple functional properties into single litter components or additive packages. Rather than adding separate substances for clumping, odor control, and absorption, the patent integrates these functions into unified formulations, reducing the total number of additives while maintaining comprehensive functionality.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A litter composition is used in the absorption of animal wastes with aqueous content in the waste. The composition may include: a particulate water-absorbing solids carrier; two solid particles of separate salts that will react in the presence of water to generate molecular iodine; and a solid acid releasing system that releases acid in the presence of the water generating iodine in sufficient amount to maintain a pH of between 3.5 and 7.5 with the reacted residue of the two solid particles and the released acid in the water.
