Solution Overview

Problem

Existing cleaning systems for hygienically sensitive areas face contamination issues when using different cleaning solutions, particularly alkaline and acidic ones, which weaken the cleaning properties due to unabsorbed residues from one solution mixing with another.

Innovation Solution

A cleaning system with spatially separated storage and collection containers for each cleaning liquid, featuring a splash-proof design and separate dosing devices to prevent contamination, along with locking mechanisms to secure the actuating elements and prevent spillage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different cleaning solutions are stored in separate containers and dosed into a shared collection container, then the cleaning system can handle multiple cleaning tasks, but contamination occurs when residues from one solution mix with another solution

Engineering Contradiction:

Improveability to use different cleaning solutionsVSAvoidcontamination of cleaning solutions

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The collection container is divided into multiple separate compartments, each assigned to a specific storage container and cleaning solution. This segmentation prevents different cleaning solutions from mixing and contaminating each other, while still allowing the system to handle multiple cleaning tasks using different solutions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediate structure (separate compartments within the collection container) that acts as a mediator between multiple storage containers and the mop cover. Each compartment serves as an isolated intermediate zone for its designated cleaning solution, preventing direct contact and contamination between different solutions while enabling sequential or simultaneous use of multiple cleaning agents.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Volume of moving object

If storage containers are positioned close together to save space, then the cleaning trolley is more compact, but splashes can cause cross-contamination between different cleaning solutions

Engineering Contradiction:

Improvespace occupied by cleaning trolleyVSAvoidsplash contamination

Core Design Contradiction:

Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The collection container is segmented into separate compartments with physical dividers that create isolated zones for each cleaning solution. This segmentation prevents splash contamination between different solutions even when storage containers are positioned close together, maintaining compactness while ensuring contamination prevention.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The partition walls between compartments act as intermediate barriers that physically separate different cleaning solutions. These intermediaries prevent direct contact between solutions during dosing operations, blocking the transmission of splashes and contaminants while allowing the system to maintain a compact footprint.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If a single collection container is used for multiple cleaning solutions, then the system structure is simpler, but the cleaning effectiveness is reduced due to solution contamination

Engineering Contradiction:

Improvestructure of collection containerVSAvoidcleaning effectiveness

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The collection container is divided into multiple compartments within a single container structure. This segmentation maintains relative structural simplicity compared to using entirely separate containers, while effectively preventing contamination between different cleaning solutions, thereby preserving cleaning effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The partition walls serve as intermediaries that maintain solution separation within a unified container structure. These intermediaries prevent cross-contamination between different cleaning solutions while keeping the overall container structure integrated and relatively simple, thus maintaining both structural simplicity and cleaning effectiveness.

Inventive Principle:

Principle #24Intermediary (Mediator)
