Solution Overview

Problem

Textile fabrics with high abrasion resistance struggle to dissipate static charges and withstand changing electric fields, posing risks to sensitive components and disrupting functions in industrial settings.

Innovation Solution

A fabric with platelet-shaped elements applied to a flexible substrate, providing both abrasion resistance and electrical charge dissipation through a conductive coating or conductive threads, ensuring electrostatic dissipative or conductive properties, and allowing for colored motifs with permanent retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a fabric with platelet-shaped elements is used to increase abrasion resistance, then abrasion resistance is improved, but static charge accumulation occurs leading to discharge currents that can damage sensitive components

Engineering Contradiction:
Improveabrasion resistanceVSAvoidstatic charge accumulation
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent applies conductive platelet-shaped elements (such as carbon-fiber-reinforced plastic platelets) to the fabric substrate. These platelets serve a dual function: they provide abrasion resistance by forming a protective surface layer, and they dissipate static electrical charges through their conductive properties. By converting the potentially harmful static charge accumulation into beneficial charge dissipation, the platelets protect sensitive components from discharge currents while maintaining the fabric's abrasion resistance.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Reliability

If the fabric is made conductive to dissipate static charges, then electrostatic dissipative properties are improved, but the aesthetic quality and color retention may be compromised

Engineering Contradiction:
Improveelectrostatic dissipative propertiesVSAvoidcolor retention and aesthetic quality
Core Design Contradiction:
ReliabilityVSIllumination intensity

Solution Approach 1:

The patent employs composite platelet-shaped elements that combine conductive materials (such as carbon fiber) with aesthetically pleasing materials (such as colored plastics or transparent coatings). This composite structure allows the platelets to provide both electrostatic dissipative properties through the conductive carbon fiber network and aesthetic quality through the colored or transparent outer layer. The conductive functionality and aesthetic appearance are thus integrated into a single multi-functional element that satisfies both requirements simultaneously.

Inventive Principle:
Principle #40Composite materials

3Reliability

If conductive platelets are applied to the substrate, then electrical conductivity is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improveelectrical conductivityVSAvoidmanufacturing process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent incorporates conductive platelet-shaped elements directly into the fabric manufacturing process, specifically during the weaving or knitting stage. The platelets are integrated into the fabric structure as it is being formed, rather than being applied as a separate post-processing step. This preliminary integration simplifies the overall manufacturing process by combining multiple functions (abrasion resistance, conductivity, and structural integrity) into a single manufacturing operation, reducing the need for subsequent assembly steps and lowering production complexity.
