Solution Overview

Problem

Existing reusable cleaning cloths are costly to produce due to multiple layers and require complex attachment methods, while disposable cloths lack effective cleaning surface texture and pose environmental concerns.

Innovation Solution

A single textile layer cleaning cloth with integrated cleaning, attachment, and stiffness provided by activated arming yarn, which can be cut to size without additional processing, using techniques like knitting or weaving and activated by heat or electromagnetic radiation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple layers are used to provide different functionalities (cleaning, support, fastening), then the cleaning performance and structural stability are improved, but the production cost and manufacturing complexity increase

Engineering Contradiction:

Improvecleaning performanceVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functional layers (cleaning fabric, support fabric, fastening fabric) into a single integrated non-woven fabric structure. This single layer incorporates different functional zones that perform cleaning, provide structural support, and enable attachment to the cleaning instrument, thereby reducing manufacturing complexity while maintaining cleaning performance.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single non-woven fabric layer is designed to perform multiple functions simultaneously: it provides cleaning surfaces with appropriate textures, offers structural support through its inherent rigidity, and includes attachment regions for securing to the cleaning instrument. This multi-functionality eliminates the need for separate layers while maintaining overall performance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Strength

If multiple layers with different functionalities are attached together, then the structural support and moisture preservation are improved, but the production stages and costs increase

Engineering Contradiction:

Improvestructural supportVSAvoidproduction cost

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The support function previously provided by a separate support fabric layer is now integrated into the single non-woven fabric structure. The fabric's inherent properties and internal architecture provide the necessary structural support without requiring additional layers or attachment processes, thereby reducing production costs.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The non-woven fabric is constructed as a composite material structure with different fiber types, densities, and arrangements within a single layer. This composite structure provides both structural support and cleaning functionality simultaneously, eliminating the need for multiple attached layers while maintaining strength and support properties.

Inventive Principle:

Principle #40Composite materials

3Ease of manufacture

If disposable non-woven fabrics are used, then the production cost is reduced, but the cleaning surface texture and environmental impact worsen

Engineering Contradiction:

Improveproduction costVSAvoidcleaning result

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The non-woven fabric is engineered with specific parameter optimizations including fiber type selection, fiber diameter distribution, fabric density, and surface texture characteristics. These parameter changes enable the single-layer disposable fabric to achieve cleaning performance comparable to multi-layer reusable cloths while maintaining cost-effectiveness and environmental benefits.

Inventive Principle:

Principle #35Parameter changes

4Object-affected harmful factors

If reusable cleaning cloths are used, then the environmental impact is reduced, but the production cost and manufacturing complexity increase

Engineering Contradiction:

Improveenvironmental impactVSAvoidproduction complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The reusable cleaning cloth design integrates multiple functional layers into a single non-woven fabric structure that can be easily attached and detached from the cleaning instrument. This merging reduces the complexity of manufacturing and assembly while maintaining the reusability and environmental benefits of reusable cloths.

Inventive Principle:

Principle #5Merging (Combining)
