Solution Overview

Problem

Existing protective textile sleeves for elongate members rely on costly and unreliable methods such as tape or glue for fixation, which can be unsightly, prone to damage, and require additional materials and labor, with glue also being ineffective at elevated temperatures and messy in application.

Innovation Solution

A protective textile sleeve with a wall of interlaced yarn featuring a water-activatable adhesive coating applied to specific areas, allowing the sleeve to bond to itself and the elongate member, reducing material usage and eliminating the need for external fixatives, while maintaining reliability and ease of application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separately applied tape is used to secure the sleeve, then the sleeve can be fixed in place, but the cost increases from material and labor standpoint and the appearance becomes unsightly if not applied correctly

Engineering Contradiction:

Improvesleeve fixation reliabilityVSAvoidmanufacturing cost and complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The adhesive layer is integrated directly into the sleeve wall structure, merging the fixation function with the sleeve body. This eliminates the need for separate tape application, reducing both material costs and labor requirements while ensuring consistent, professional appearance.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The sleeve includes self-contained adhesive capability through the integrated adhesive layer, allowing it to secure itself to the elongate member without requiring external tape or additional fixation materials. The adhesive layer is activated during installation to provide reliable fixation.

Inventive Principle:

Principle #25Self-service

2Reliability

If externally applied tape is used, then the sleeve can be fixed, but the tape can become inadvertently damaged or ineffectively applied during assembly, thus adversely affecting the ability to reliably fix the sleeve

Engineering Contradiction:

Improvefixation reliabilityVSAvoidapplication ease and consistency

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The adhesive layer is pre-applied and integrated into the sleeve wall during manufacturing, ensuring proper positioning and protection before installation. This preliminary preparation eliminates the risk of incorrect application, folding, or contamination that occurs with separate tape application during assembly.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If separately applied glue is used during assembly, then the sleeve can be fixed, but the cost increases from material and labor standpoint and drying time is required

Engineering Contradiction:

Improvefixation reliabilityVSAvoidassembly time and drying time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The adhesive layer is combined with the sleeve wall structure, eliminating the need for separate glue application steps. The adhesive is already positioned correctly on the sleeve, allowing immediate fixation without additional material application or drying等待 time during assembly.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If glue is used for fixation, then the sleeve can be attached, but the glue lacks strength at elevated temperatures and becomes messy in application

Engineering Contradiction:

Improvefixation strengthVSAvoidtemperature sensitivity and messiness

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The adhesive layer is designed with specific material properties that provide temperature resistance and controlled adhesion characteristics. The adhesive formulation maintains bonding strength at elevated temperatures and allows for clean, controlled application without messiness during installation.

Inventive Principle:

Principle #35Parameter changes
