Braided Sleeve X/Y Pattern Monofilament Multifilament Abrasion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile sleeves for protecting elongate members, such as wire harnesses, often fall short in providing optimal protection against abrasion and impact due to stiffness, lack of flexibility, and high manufacturing costs, with woven sleeves being too stiff and knitted sleeves being too elastic and bulky.
Innovation Solution
A braided protective sleeve with a wall formed by braided yarns in an X/Y braid pattern, where the yarns with the greater numerical value are multifilaments and those with the lesser value are monofilaments, and additional inserted yarns can be interlaced to enhance protection and attachment features, providing a circumferentially continuous, seamless structure with adjustable edge overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If woven textile sleeve is used, then abrasion resistance is improved, but radial flexibility deteriorates
Solution Approach 1:
The patent applies composite materials by combining different yarn types (monofilament and multifilament) in a braided structure. The monofilament yarns provide abrasion resistance while the multifilament yarns contribute to radial flexibility, creating a composite textile that resolves the contradiction between these two properties.
Solution Approach 2:
The patent changes the structural parameters by using an X/Y braid pattern where X and Y are different numerical values, creating a balanced braid structure. This parameter change allows the sleeve to achieve both abrasion resistance and radial flexibility by optimizing the interlacing pattern of the yarns.
2Ease of operation
If knitted textile sleeve is used, then radial flexibility is improved, but structural stability deteriorates
Solution Approach 1:
The patent uses composite materials combining monofilament and multifilament yarns in a braided structure. The monofilament yarns provide structural stability while the multifilament yarns maintain radial flexibility, resolving the contradiction between these properties through material composition.
Solution Approach 2:
The patent employs an X/Y braid pattern with different numerical values to change the structural parameters. This creates a balanced braid that maintains structural stability while preserving radial flexibility, overcoming the limitations of traditional knitted structures.
3Reliability
If traditional woven or knitted sleeve is used, then protection function is provided, but manufacturing cost increases
Solution Approach 1:
The patent adopts a braided construction method that is simpler and more cost-effective than traditional woven or knitted processes. The braiding process allows for continuous production with fewer steps, reducing manufacturing costs while maintaining protective functionality.
Solution Approach 2:
The patent changes the manufacturing approach by using a braided structure with X/Y pattern instead of traditional weaving or knitting. This parameter change in the construction method simplifies the manufacturing process and reduces costs while preserving the protective function.

AI summary
A braided protective sleeve and method of construction thereof is provided. The sleeve has a wall extending along a longitudinal axis of the sleeve. The wall includes a plurality of braided yarns forming inner and outer surfaces of the sleeve. The inner surface bounds an internal cavity and the outer surface is exposed to the surrounding environment. The yarns are braided with one another in a X/Y braid pattern with X and Y being different numerical values from one another. The numerical values of X and Y can be selected as desired to provide the sleeve with the enhanced physical performance characteristics desired. A plurality of yarns extending substantially parallel to the longitudinal axis can be interlaced with the braided yarns. The interlaced yarns can be exposed to the internal cavity and concealed from the environment; exposed to the environment and concealed from the internal cavity, or both.
