Multilayer Textile Sleeve With Interlinked Layers for Flexible Protection
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 adequate protection against exposure and damage 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 featuring a weaving process that provides enhanced protection and rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate sleeves are manufactured and wrapped individually, then protection against exposure in crash conditions is provided, but manufacturing efficiency decreases and cost increases
Solution Approach 1:
The patent combines multiple protective layers into a single integrated sleeve structure with inner and outer layers that are connected at seams but detached in central portions. This merging eliminates the need to manufacture, stock, and wrap separate sleeves individually, thereby improving manufacturing efficiency while maintaining the protective function against exposure in crash conditions
2Reliability
If separate sleeves are used, then protection is provided, but space occupation increases
Solution Approach 1:
By integrating multiple protective layers into a single sleeve with connected seams and detached central portions, the patent reduces the overall volume and space occupation compared to using multiple separate sleeves, while maintaining the required protection level
3Reliability
If separate sleeves are manufactured, then protection is achieved, but inventory complexity increases
Solution Approach 1:
The integrated sleeve design with inner and outer layers connected at seams reduces inventory complexity by eliminating the need to stock and manage multiple separate sleeve types, while maintaining the protective functionality through the multi-layer construction
4Strength
If layers are integrally connected across the entire surface, then structural strength is improved, but flexibility and routing capability decrease
Solution Approach 1:
The patent segments the connection between inner and outer layers by connecting them only at seam portions while leaving central portions detached. This segmentation provides structural strength at the seams where needed while maintaining flexibility and routing capability in the central portions, allowing the sleeve to be routed around corners

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.
