Multilayer Textile Sleeve With Interlinked Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multilayer textile sleeve manufacturing processes are inefficient and costly due to separate construction and wrapping of individual layers, leading to increased material usage, space occupation, and inventory complexity, while failing to provide effective protection against exposure in crash conditions.
Innovation Solution
A multilayer textile sleeve with interlinked inner and outer layers constructed in a single process, where the layers are integrally connected at the edges but remain detached in the central portion, allowing for flexibility and reduced material usage, and are woven using monofilaments or multifilaments for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate sleeves are manufactured and wrapped individually, then protection against exposure and damage is provided, but manufacturing efficiency decreases and costs increase
Solution Approach 1:
The patent combines multiple protective sleeves into a single integrated multilayer textile structure. The inner layer and outer layer are constructed together in one weaving process rather than separately, eliminating the need for separate manufacturing and wrapping operations. This merging maintains the protective function while significantly improving manufacturing efficiency and reducing costs.
Solution Approach 2:
The integrated sleeve is divided into distinct functional layers (inner layer and outer layer) that are woven together as one piece. Each layer provides specific protective properties, and the segmentation is achieved through the weaving structure itself rather than through separate components, resolving the contradiction between integration for efficiency and segmentation for function.
2Reliability
If separate sleeves are used, then adequate protection is achieved, but space occupation increases
Solution Approach 1:
By merging multiple protective functions into a single multilayer textile sleeve, the patent reduces the total volume occupied compared to using separate sleeves. The integrated structure allows the layers to be tightly bound together in one cohesive unit, minimizing the space required while maintaining all protective functions.
3Reliability
If separate sleeves are manufactured and stocked, then protection requirements are met, but inventory complexity increases
Solution Approach 1:
The patent merges multiple protective functions into a single product type (multilayer textile sleeve), thereby reducing inventory complexity. Instead of stocking separate inner sleeves and outer sleeves that need to be matched and assembled, the integrated design requires only one product type to fulfill all protective requirements, simplifying inventory management.
4Strength
If edges overlap to bound cavity, then structural integrity is provided, but material usage increases
Solution Approach 1:
The sleeve is segmented into distinct layers (inner and outer) that are woven together, allowing the overlapping edges to provide structural integrity for bounding the cavity while minimizing material usage through efficient layer integration. The segmentation enables each layer to contribute to structural strength without requiring excessive material.

AI summary
A multilayer textile sleeve and method of construction thereof is provided. The sleeve includes a textile wall having opposite edges extending lengthwise along a longitudinal axis of the sleeve between opposite ends. The opposite edges are configured to overlap one another to bound a central cavity of the sleeve. The wall has an inner layer with opposite inner and outer faces and an outer layer with opposite inner and outer faces. The inner and outer layers overlap one another and are constructed of interlinked yarn. The inner and outer layers are integrally connected to one another across interlinked portions adjacent the opposite edges by yarn common to each of the inner and outer layers.
