Current cat litter cleaning systems are inefficient, requiring significant time and effort to remove waste clumps from litter, and lack hygienic design and cost-effectiveness.

Innovation Solution

A cat litter box cleaning system featuring a base with layer securing fixtures and alternating layers of sieves and liners, allowing for easy separation of waste clumps from litter granules, with sieves and liners designed to prevent cat interference and facilitate easy removal and disposal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual digging is used to remove waste clumps, then waste removal is possible, but cleaning time and effort increase significantly

Engineering Contradiction:

Improvecleaning speedVSAvoidtime spent cleaning

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The cleaning system divides the litter box into multiple separable layers (sieves and liners) that can be independently removed. Each layer captures waste clumps at different depths, allowing systematic removal of waste without manually digging through the entire litter volume, thus significantly reducing cleaning time and effort.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention extracts waste clumps from the litter through the sieve layers with openings that allow waste to be separated from clean litter granules. The waste is captured on the sieve surfaces and can be easily removed by lifting the sieve layers, eliminating the need for manual digging and reducing cleaning time.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of manufacture

If simple sieve structures are used, then manufacturing cost is reduced, but cat interference and damage increase

Engineering Contradiction:

Improvemanufacturing costVSAvoidcat damage to sieves

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The invention introduces liners as intermediary protective layers between the cat and the sieve structures. These liners are positioned beneath the sieve layers and prevent direct contact between the cat's claws and the sieve, reducing damage while maintaining the simple sieve design for cost-effectiveness.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention uses flexible liner materials (such as plastic or rubber sheets) that can be easily placed and removed. These thin film liners protect the sieve structures from cat interference while maintaining simplicity and cost-effectiveness in manufacturing.

Inventive Principle:

Principle #30Flexible shells and thin films

3Productivity

If multiple layers of sieves and liners are added, then waste removal efficiency improves, but device complexity increases

Engineering Contradiction:

Improvewaste removal efficiencyVSAvoidnumber of layers

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The invention segments the waste removal function across multiple simple layers (sieves and liners) that can be independently removed and cleaned. Each layer performs a specific function in capturing waste clumps at different depths, and the modular design allows efficient waste removal without requiring complex integrated mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sieve and liner layers are pre-positioned in the litter box before the cat uses the box. This preliminary arrangement ensures that waste clumps are automatically captured and separated from clean litter as the cat eliminates, eliminating the need for complex active waste removal mechanisms and simplifying the overall device.

Inventive Principle:

Principle #10Preliminary 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 system significantly reduces the time and effort required for cleaning by allowing waste clumps to be easily removed and disposed of, while maintaining hygiene and being cost-effective to manufacture and use.

Implementation Method 1

The first sieve has a plurality of openings formed therein. The openings are large enough to allow unused litter granules to pass through the openings while at the same time prohibiting waste clumps from passing through the openings.

Methodology Applied

Scientific EffectPhysical filtration: Filter (physical)

Implementation Method 2

The first liner shields the first sieve from the cat.

Methodology Applied

Scientific EffectPhysical protection: Physical Containment

AI summary

A cat litter box cleaning system designed to sieve waste clumps from cat litter is provided. The cat litter box cleaning system has multiple layers thereby providing multiple cleaning operations. The layers may consist of a sieving layer and a liner. The liner shields the sieving layer from the cat's claws and the sieving layer is used to remove the waste from the litter. Each sieving layer and liner releasably cooperates with layer securing fixtures. The layer securing fixtures releasably attach the layers to a base and prevent the cat from dislodging the sieves or liners. Access ports may be provided for removing the layers from the layer securing fixtures without having to come into contact with the cat litter. A method is provided where at least two cat litter box cleaning systems are utilized to ensure that fresh cat litter always forms the basis of the litter used.
