Solution Overview

Problem

Existing robot sweepers are unable to effectively clean the finishing cloth, leading to secondary pollution and increased user burden due to the need for manual assembly and disassembly, which results in incomplete floor cleaning.

Innovation Solution

A floor cleaning apparatus comprising a cleaning robot with a mop assembly and a washing base that includes a rinse tank and solution-feeding mechanism, allowing the finishing cloth to be automatically washed and cleaned, reducing the need for manual intervention and preventing secondary pollution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the finishing cloth is not cleaned, then the cleaning burden on users is reduced, but the floor cleaning quality deteriorates due to secondary pollution

Engineering Contradiction:
Improvecleaning burdenVSAvoidfloor cleaning quality
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The finishing cloth cleaning system enables the robot sweeper to automatically clean its own finishing cloth through the washing base. The system includes a rinse tank with washing components (spray holes, bristles, scraping plate) that automatically wash the finishing cloth during docking, eliminating the need for manual cleaning while maintaining cleaning quality.

Inventive Principle:
Principle #25Self-service

2Device complexity

If manual assembly and disassembly is required for cleaning, then the structure is simple, but the operation convenience deteriorates

Engineering Contradiction:
ImprovestructureVSAvoidoperation convenience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The system automatically cleans the finishing cloth through the washing base with rinse tank and washing components, eliminating the need for manual assembly and disassembly. The robot sweeper docks with the washing base and the finishing cloth is automatically washed while attached, improving operation convenience without significantly increasing structural complexity.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the finishing cloth is continuously used without cleaning, then the operation is simple, but harmful effects increase due to secondary pollution

Engineering Contradiction:
Improveoperation simplicityVSAvoidsecondary pollution
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The washing base with rinse tank and washing components automatically cleans the finishing cloth during docking, preventing secondary pollution while maintaining operational simplicity. The system includes spray holes for wetting, bristles for scrubbing, and scraping plate for removing dirt and solution.

Inventive Principle:
Principle #25Self-service

4Manufacturing precision

If automatic washing mechanism is added, then the cleaning quality is improved, but the device complexity increases

Engineering Contradiction:
Improvecleaning qualityVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The washing base is designed as a separate module from the robot sweeper, with the rinse tank and washing components (spray holes, bristles, scraping plate) as distinct functional elements. This segmentation allows automatic washing functionality to be added without significantly increasing the complexity of the main robot sweeper structure.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles
