Solution Overview

Problem

Existing three-dimensional cleaning textiles face challenges in achieving a high deep structure using the same fibers or yarns, while maintaining good cleaning performance, water absorption, and low friction for extended service life.

Innovation Solution

A three-dimensional cleaning textile is designed with a plush cleaning back and a front featuring at least one polar yarn that towers over, forming loop-shaped or cut floral structures. The polar yarn penetrates the cleaning back and is connected to the back, with varying floring heights to adapt to different cleaning conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a three-dimensional cleaning textile is designed with high/low structure using the same fibers or yarns, then the cleaning performance and adaptability are improved, but the manufacturing complexity increases

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

Solution Approach 1:

The textile surface is segmented into different pile height zones (first pile height and second pile height greater than the first) within the same plush fabric, creating functional zones with varying cleaning characteristics without requiring different materials

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the textile front side have locally differentiated pile heights, where the second pile height regions provide enhanced cleaning action while the first pile height regions provide softer contact, allowing adaptation to different cleaning conditions within a single textile

Inventive Principle:
Principle #3Local quality

2Quantity of substance

If the pile yarn forms loop-shaped pile nubs or cut pile with third pile height greater than the second pile height, then dirt absorption capability is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvedirt absorption capabilityVSAvoidpile height control precision
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The pile yarn is pre-configured with loop-shaped pile nubs or cut pile structure before being integrated into the plush fabric, ensuring the third pile height (greater than second pile height) is established during fabric formation rather than requiring post-processing

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The pile yarn structure is designed to naturally exhibit three different pile heights (first, second, and third where third > second > first) through its construction, allowing the higher third pile height regions to effectively trap and hold dirt particles while maintaining manufacturing feasibility

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the cleaning textile exhibits low friction when moved over the surface to be cleaned, then ease of operation is improved, but the cleaning effectiveness may be reduced

Engineering Contradiction:
Improveease of movement over surfaceVSAvoidcleaning effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The textile surface features local variations in pile height where lower first pile height regions provide smooth contact for easy movement and low friction, while higher second and third pile height regions provide enhanced cleaning action and dirt trapping, combining ease of operation with cleaning effectiveness in different zones

Inventive Principle:
Principle #3Local quality
