Composite Monofilament Textile Sleeve for Non-Abrasive Protection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing textile sleeves fail to provide adequate protection against abrasion of elongate members and neighboring objects while maintaining economic manufacturing, as they often cause abrasion due to their interaction with the contents and surrounding components.

Innovation Solution

A textile sleeve formed with a combination of first and second monofilaments interlaced with one another. The first monofilaments are a homopolymer material and the second monofilaments are woven or braided together, with the second monofilaments containing a copolymer material that includes resin with excellent sliding characteristics, such as UHMW-PE, to provide excellent sliding characteristics and a balance of PET or PA, and the first monofilaments are woven or braided with one another. The second monofilaments are a copolymer material with a diameter greater than the first, and the second monofilaments are woven or braided with one another.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a textile sleeve is made from conventional materials to protect elongate members, then protection against impact and contamination is provided, but abrasion resistance is compromised and the sleeve causes abrasion to contents and neighboring objects

Engineering Contradiction:

Improveprotection against impact and contaminationVSAvoidabrasion to elongate member and neighboring objects

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The textile sleeve employs a composite structure combining two distinct monofilament materials: first monofilaments made from homopolymer material (providing structural integrity and protection) and second monofilaments made from copolymer material containing resin with excellent sliding characteristics (providing abrasion resistance and non-abrasive properties). This composite approach allows the sleeve to simultaneously protect against impact/contamination while preventing abrasion to contents and neighboring objects.

Inventive Principle:

Principle #40Composite materials

2Object-affected harmful factors

If the sleeve material is made softer to reduce abrasion to contents, then sliding characteristics improve, but mechanical strength and protection capability deteriorate

Engineering Contradiction:

Improveabrasion to elongate memberVSAvoidmechanical strength and protection capability

Core Design Contradiction:

Object-affected harmful factorsVSStrength

Solution Approach 1:

The sleeve wall is segmented into two functional layers at the micro-level: first monofilaments providing mechanical strength and structural protection, and second monofilaments providing sliding characteristics and abrasion resistance. This segmentation allows each material component to perform its specific function optimally without compromising the other, resolving the contradiction between softness for sliding and strength for protection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The composite material structure combines homopolymer and copolymer monofilaments in a unified textile wall, where the homopolymer component maintains mechanical strength while the copolymer component with sliding characteristics prevents abrasion. This composite approach enables simultaneous achievement of both protection capability and abrasion resistance.

Inventive Principle:

Principle #40Composite materials

3Reliability

If the textile sleeve is made more durable to protect against abrasion, then protection capability improves, but manufacturing cost increases

Engineering Contradiction:

Improveabrasion resistanceVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The textile sleeve uses a cost-effective composite material system where the homopolymer monofilaments provide the primary structural framework at lower cost, while the copolymer monofilaments with sliding characteristics provide the abrasion resistance. This layered composite approach achieves durable abrasion resistance without requiring entirely expensive materials, thus managing manufacturing costs while improving reliability.

AI summary

A textile sleeve for routing and protecting an elongate member has a textile wall having an inner surface and an opposite outer surface extending lengthwise along a central longitudinal axis between opposite ends. The inner surface bounds a cavity sized for receipt of the elongate member. The textile wall is formed of first monofilaments and second monofilaments interlaced with one another. The first monofilaments are a homopolymer material and the second monofilaments are a copolymer material.
