Solution Overview

Problem

The existing cleaning tools lack versatility due to having identical fiber layers on both sides of the grip insertion part, limiting their usability.

Innovation Solution

A cleaning tool with a cleaning sheet and holder, featuring a brush part composed of two fiber assemblies with different finenesses, materials, and structures for the first and second brush parts, allowing for varied cleaning functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the same fiber layer structure is used on both sides of the grip insertion part, then the manufacturing process is simple, but the versatility of the cleaning tool is limited

Engineering Contradiction:
ImproveversatilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by providing different fiber layer structures on the upper and lower sides of the grip insertion part. The upper fiber layer has a first structure suitable for dry cleaning, while the lower fiber layer has a second structure suitable for wet cleaning, allowing each region to have optimized properties for its specific cleaning function.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The cleaning tool is segmented into functionally distinct regions with different fiber layer structures. The upper and lower fiber layers are separated and independently designed, enabling the tool to perform multiple cleaning functions (dry and wet cleaning) simultaneously on different surfaces.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If different fiber layer structures are used on both sides of the grip insertion part, then the versatility and usability are improved, but the manufacturing complexity increases

Engineering Contradiction:
ImproveusabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

Different fiber layer structures are implemented on opposite sides of the grip insertion part to provide specialized cleaning capabilities. The upper fiber layer uses finer fibers for gentle cleaning, while the lower fiber layer uses coarser fibers for scrubbing, enhancing overall usability.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The cleaning tool achieves multi-functionality by combining different fiber layer structures that enable both dry cleaning and wet cleaning operations, allowing a single tool to handle various cleaning scenarios and surface types.

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

3Adaptability or versatility

If the brush part has regions with different structures, then the cleaning functionality is enhanced, but the device complexity increases

Engineering Contradiction:
Improvecleaning functionalityVSAvoidbrush part structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The brush part is divided into regions with different fiber structures - the first brush part has fibers with a first fineness for gentle cleaning, while the second brush part has fibers with a second fineness for more aggressive cleaning, allowing localized optimization for different cleaning needs.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The brush part is segmented into multiple functional regions with distinct fiber characteristics, enabling the cleaning tool to address various types of soil and surface materials within a single cleaning operation.

Inventive Principle:
Principle #1Segmentation
