Solution Overview

Problem

Existing cleaning textiles with microfibers often cause surface damage during cleaning in clean rooms due to abrasive effects and the risk of microfiber separation, leading to dirt accumulation and reduced cleaning quality.

Innovation Solution

A three-dimensional chain mesh cleaning textile with a first and second wall area connected by polar threads, featuring thread systems with filaments of at least 100 DTEX and 90 filaments for the first wall area, and at least 70 DTEX and 20 filaments for the second wall area, utilizing tetralobal cross-section filaments for enhanced strength and absorbency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If microfibers are used in cleaning textiles, then absorbency is improved, but surface damage occurs due to abrasive effects and microfiber detachment

Engineering Contradiction:
ImproveabsorbencyVSAvoidsurface damage
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent changes the fiber parameters by using macrofibers with a minimum linear density of 1.5 dtex instead of microfibers, and specifically employs tetralobal cross-section filaments. This parameter change maintains absorbency while eliminating the abrasive effects and detachment issues associated with microfibers, as the larger fiber diameter provides structural stability and reduced surface abrasiveness.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The cleaning textile uses a composite structure combining different yarn systems with distinct functions: one yarn system provides structural stability with higher linear density, while another provides cleaning functionality. The pile yarns connect these systems, creating a composite material that achieves both high absorbency and gentle surface interaction without relying on microfibers.

Inventive Principle:
Principle #40Composite materials

2Reliability

If microfibers are used to enhance cleaning capability, then dirt removal is improved, but the risk of microfiber detachment and contamination increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidmicrofiber detachment
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the critical parameter of fiber linear density from microfiber scale to macrofiber scale (minimum 1.5 dtex), which fundamentally alters the detachment behavior. The tetralobal cross-section provides additional structural integrity through its four-lobed geometry, distributing stress more evenly and preventing the fiber-end detachment that plagues conventional microfiber textiles while maintaining cleaning effectiveness.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The tetralobal cross-section introduces a specific geometric curvature pattern that enhances fiber interlocking and structural stability. This curved, multi-lobed geometry prevents the linear fibers from easily separating or detaching during use, while the lobed structure maintains effective surface contact for dirt removal.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Reliability

If frequent cleaning is performed to maintain hygiene standards, then cleanliness is improved, but surface damage accumulates due to abrasive microfibers

Engineering Contradiction:
Improvehygiene standardsVSAvoidsurface integrity
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent changes the fiber linear density parameter to macrofiber scale (minimum 1.5 dtex), which fundamentally reduces the abrasive effect on surfaces. This allows frequent cleaning operations to be performed while maintaining surface integrity, as the larger fiber diameter creates less friction and mechanical damage compared to fine microfibers.

Inventive Principle:
Principle #35Parameter changes

4Productivity

If reusable cleaning textiles are used to reduce waste, then productivity is improved, but durability requirements increase

Engineering Contradiction:
ImprovereusabilityVSAvoiddurability
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The patent employs a composite yarn structure with at least two different yarn systems, where one system provides structural strength and stability for durability, while another provides cleaning functionality. The pile yarns connect these systems, creating a composite textile that meets both reusability and durability requirements through synergistic material combination.

Inventive Principle:
Principle #40Composite materials
