Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective sheaths for electrical cables and energy storage units in vehicles are heavy and inflexible, posing installation challenges and being costly due to the high demand for materials like aramid fibers.
Innovation Solution
A textile fabric is developed with a woven structure comprising longitudinal and transverse threads forming force redirection structures, allowing for flexible and lightweight protection, using materials such as polyester, aramid, glass, or carbon fibers, and optionally incorporating elastic properties for radial expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanically stable materials are used for protective sheaths, then protection function is improved, but weight increases and flexibility deteriorates
Solution Approach 1:
The patent applies this principle by using a textile fabric sheath made of flexible threads (aramid, polyester, or polypropylene) instead of rigid mechanically stable materials. The textile structure provides protection through its woven configuration and force redirection capability while maintaining flexibility and reducing weight compared to traditional rigid protective materials.
Solution Approach 2:
The patent applies this principle by creating a composite textile fabric structure combining different thread types (aramid, polyester, polypropylene) with specific weaving patterns. This composite structure achieves the desired balance between protection function, weight, and flexibility by leveraging the properties of multiple materials in a coordinated fabric architecture.
2Reliability
If mechanically stable materials are used for protective sheaths, then protection function is improved, but ease of installation deteriorates
Solution Approach 1:
The textile fabric sheath provides ease of installation through its inherent flexibility and conformability, allowing it to be easily wrapped around and secured to cables and energy storage units. The flexible nature enables simple installation without requiring complex mounting procedures.
Solution Approach 2:
The patent applies this principle by designing the textile fabric with dynamic characteristics that allow it to adapt to different installation scenarios. The fabric can be easily manipulated, wrapped, and secured around various shapes and sizes of protected objects, providing installation flexibility.
3Strength
If aramid fibers are used for textile protective sheath, then impact resistance is improved, but cost increases
Solution Approach 1:
The patent applies this principle by using aramid fibers selectively in specific regions or layers of the textile fabric where maximum impact resistance is needed, while combining them with more cost-effective materials like polyester or polypropylene in other areas. This localized approach maintains necessary protection while reducing overall material costs.
Solution Approach 2:
The patent applies this principle by creating a composite textile structure that combines aramid fibers with polyester and/or polypropylene threads. This composite approach achieves the desired impact resistance through the aramid components while the other materials provide cost-effective support and structural integrity, reducing overall cost compared to using 100% aramid.

The textile fabric provides effective mechanical protection while reducing weight and improving installation ease, offering flexibility and resistance to impact, suitable for sheathing electrical cables or protecting energy storage units.
Implementation Method 1
force redirection structures running in the transverse direction are formed... each respective force redirection structure is designed so as to cause, under force application, in particular in a normal direction of the fabric-body, at least a force redirection at least in the longitudinal direction
Implementation Method 2
the longitudinal and transverse threads of the tube have elastic properties so that the tube can be expanded radially

AI summary
The application is directed on a textile fabric, preferably a woven fabric, including a textile fabric-body formed by a first thread group, of longitudinal threads, running in a longitudinal direction of the textile fabric-body, and a second thread group, of transverse threads, running in a transverse direction of the textile fabric-body, the first thread group and the second thread group being linked/combined with each other via the respective longitudinal and transverse threads such that force redirection structures running in the transverse direction are formed (i) alternately on one side and another side of the textile fabric-body with a respective offset in the longitudinal direction, or (ii) on one side of the textile fabric-body with a respective offset in the longitudinal direction, wherein each respective force redirection structure is designed so as to cause, under force application, in particular in a normal direction of the fabric-body, at least a force redirection at least in the longitudinal direction of the textile fabric-body.
