Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automotive protective coatings for electrical cables and energy storage devices are heavy and inflexible due to the use of mechanically stable materials, and alternatives like aramid fibers are expensive and in high demand for ballistic applications.
Innovation Solution
A lightweight textile fabric with a woven structure featuring longitudinal and transverse threads linked via force diversion structures, allowing for force redirection and elasticity, which can be used to protect electrical components without the weight and cost issues of traditional materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanically stable materials are used for protective sheaths, then mechanical protection is improved, but weight increases and flexibility deteriorates
Solution Approach 1:
The patent uses a composite textile structure combining polyester fibers (providing flexibility and light weight) with aramid fibers or other high-strength materials (providing mechanical protection). This composite approach achieves the required strength while maintaining low weight and high flexibility, resolving the contradiction between mechanical protection and weight.
2Strength
If aramid fibers are used for protective sheaths, then impact resistance is improved, but cost increases and availability deteriorates
Solution Approach 1:
The patent applies aramid fibers or other high-strength materials only in specific locations where maximum protection is needed, rather than using them throughout the entire sheath. The textile structure strategically places these expensive high-performance fibers to provide impact resistance at critical points, while using more economical polyester fibers in other areas, thus reducing overall cost and improving availability.
Solution Approach 2:
The patent creates a composite textile structure that combines polyester fibers (cost-effective, readily available) with aramid fibers (high impact resistance) in a blended or layered configuration. This allows the sheath to achieve adequate impact resistance through the synergistic effect of the composite materials while significantly reducing the amount of expensive aramid fiber needed compared to using aramid alone, thereby lowering cost and improving availability.
3Strength
If mechanically stable materials are used for protective sheaths, then mechanical protection is improved, but flexibility deteriorates
Solution Approach 1:
The patent employs a composite textile structure combining flexible polyester fibers with high-strength aramid fibers or other reinforcement materials. The polyester component provides the necessary flexibility for easy installation and conforming to cable shapes, while the aramid component delivers the mechanical protection required. This composite approach resolves the contradiction by allowing both flexibility and strength to coexist in the same material system.
