Solution Overview

Problem

Existing textile materials that offer abrasion resistance, protection from contact heat, and breathability are often stiff and lack flexibility, making them unsuitable for applications requiring both durability and comfort, such as sports and protective clothing.

Innovation Solution

A textile surface product with a carrier layer and strategically arranged abrasion-resistant coating elements made from a mixture of polymer and inorganic/metallic particles, which are designed to absorb friction and heat while maintaining flexibility, ensuring that the carrier layer remains protected from abrasion and heat exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional materials like leather or plastic-based materials are used for abrasion resistance, then abrasion resistance is improved, but breathability deteriorates and flexibility is reduced

Engineering Contradiction:
Improveabrasion resistanceVSAvoidflexibility
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The protective function is segmented by applying discrete coating elements (dots, patches, or patterns) rather than a continuous coating. This segmentation allows the carrier layer to maintain flexibility in uncoated areas while providing abrasion resistance where coating elements are present.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Abrasion-resistant coating elements are applied locally to specific areas of the textile surface rather than uniformly across the entire material. This localized application provides protection where needed while preserving the flexibility and breathability of the underlying carrier layer in non-coated regions.

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If materials of certain thickness are used to protect against contact heat, then protection against contact heat is improved, but flexibility deteriorates

Engineering Contradiction:
Improveprotection against contact heatVSAvoidflexibility
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

Thin coating elements comprising polymer and filler particles are applied to the textile surface to provide heat protection. These thin film-like coatings offer thermal protection without the stiffness associated with thicker materials, maintaining the flexibility of the underlying carrier layer.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The coating elements are composed of composite materials combining polymer matrices with filler particles (such as inorganic or metallic particles). This composite structure provides heat resistance through the filler while the polymer matrix maintains flexibility and adhesion to the carrier layer.

Inventive Principle:
Principle #40Composite materials

3Strength

If a continuous coating is applied to provide abrasion resistance, then abrasion resistance is improved, but flexibility and breathability of the carrier layer deteriorate

Engineering Contradiction:
Improveabrasion resistanceVSAvoidflexibility
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

Instead of a continuous coating, the protective layer is segmented into discrete coating elements distributed across the carrier layer surface. This segmentation preserves the flexibility and breathability of the carrier layer while providing adequate abrasion resistance through the distributed protective elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Rather than applying a complete continuous coating, only partial coverage with discrete coating elements is applied. This partial action is sufficient to provide the required abrasion resistance while avoiding the negative effects of a full continuous coating on flexibility and breathability.

Inventive Principle:
Principle #16Partial or excessive action
