Solution Overview

Problem

Conventional floor mops have limitations such as single cleaning surface, inadequate pressure transmission, difficulty in cleaning narrow spaces, and inconvenient attachment mechanisms, which restrict their effectiveness on both ordinary and stubborn stain floors.

Innovation Solution

A cleaning device with a pivoting mechanism that allows for two distinct cleaning surfaces, one on the supporting plate and one on a side plate, which can be angled to provide different cleaning materials and areas for effective cleaning of various surfaces and spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single cleaning surface is used on the supporting plate, then the structure is simple, but the adaptability to different cleaning needs (ordinary floor vs. stubborn stains) is limited

Engineering Contradiction:
Improveadaptability to different cleaning needsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cleaning device is divided into multiple independent cleaning surfaces: a first cleaning surface on the supporting plate and a second cleaning surface on a detachable side plate. Each surface can be independently selected and used according to different cleaning needs, allowing the device to handle both ordinary floor cleaning and stubborn stain removal without requiring a completely different tool for each task.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The supporting plate and side plate both incorporate cleaning surfaces with different cleaning materials, enabling the same base device to perform multiple cleaning functions. The user can switch between the first cleaning surface for ordinary floors and the second cleaning surface for stubborn stains, making the device universally applicable to various cleaning scenarios.

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

2Stress or pressure

If a large supporting plate is used to increase cleaning area, then the cleaning area is large, but the pressure transmission to the floor is insufficient

Engineering Contradiction:
Improvepressure transmission intensityVSAvoidcleaning area
Core Design Contradiction:
Stress or pressureVSArea of stationary object

Solution Approach 1:

The cleaning area is segmented into two distinct plates: a larger supporting plate for general cleaning areas and a smaller side plate for concentrated pressure applications. This segmentation allows the user to select the appropriate plate size for each specific cleaning task, optimizing both pressure transmission and cleaning area coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different cleaning surfaces are provided on different plates to match different cleaning requirements. The first cleaning surface on the supporting plate is suited for large-area cleaning, while the second cleaning surface on the side plate is designed for applications requiring concentrated pressure on stubborn stains, thereby optimizing local cleaning quality.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If a large supporting plate is used to increase cleaning area, then the cleaning area is large, but the ability to clean narrow spaces is reduced

Engineering Contradiction:
Improveability to clean narrow spacesVSAvoidcleaning area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The cleaning system is segmented into a large supporting plate and a smaller detachable side plate. The side plate's compact size makes it suitable for navigating narrow spaces and ambiguous areas, while the larger supporting plate maintains overall cleaning area efficiency. Users can switch between plates depending on the spatial constraints of the cleaning task.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The side plate is designed to be detachable and pivotable, allowing dynamic adjustment of the cleaning device's configuration. This dynamic structure enables the device to adapt to different spatial requirements, entering narrow spaces when needed while maintaining large-area cleaning capability when appropriate.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If conventional attachment mechanisms are used for the mop cloth, then the structure is simple, but the convenience and reliability of attachment are insufficient

Engineering Contradiction:
Improveconvenience of mop cloth attachmentVSAvoidattachment mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The side plate is designed with a pivotable connection to the supporting plate, allowing dynamic adjustment and easy detachment. This dynamic mechanism enables convenient replacement of the side plate and its associated mop cloth, improving ease of operation while maintaining reasonable structural complexity through the use of simple pivot joints.

Inventive Principle:
Principle #15Dynamics

AI summary

The cleaning device of the present invention comprises: a cleaning portion, the cleaning portion is provided with a cleaning surface and an opposite surface opposed to the cleaning surface; a supporting arm (4); and a pivoting mechanism (5) for pivotably supporting the supporting arm (4) on the opposite surface. The cleaning surface (3) of the cleaning portion includes a first cleaning material surface (3a) and a second cleaning material surface (3b), the first cleaning material surface (3a) and the second cleaning material surface (3b) come into contact with the surfaces to be cleaned, respectively. When any one of the first cleaning material surface (3a) and the second cleaning material surface (3b) comes into contact with the surface to be cleaned, the other cleaning material surface has an angle (α) from 90 degrees to 180 degrees with respect to the surface to be cleaned.
