Nylon Webbing with Hard Polymer Edge Coating for Cut Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Webbings used for securing cargo or tow straps are prone to wear-and-tear damage, particularly cutting and fraying, due to their exposure in rough environments, which can lead to accidents and injuries.
Innovation Solution
A webbing design featuring a main portion made of nylon fibers with a protective edge portion composed of nylon fibers encased in a hard polymer coating, such as Polybutylene Terephthalate (PBT), which provides enhanced durability and resistance to cutting and fraying by distributing impact and frictional forces away from the uncoated fibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If webbing is used in rough environments for securing cargo or towing, then the webbing provides durable connection and load-bearing capability, but the webbing edges are prone to cutting and fraying damage
Solution Approach 1:
The patent applies different material properties to different parts of the webbing: the core webbing uses flexible nylon fibers for load-bearing, while the edge portions use hard polymer-coated threads for cut and fray resistance. This local differentiation of material quality resolves the contradiction between needing flexibility for strength and hardness for edge protection.
Solution Approach 2:
The patent creates a composite structure by combining nylon fibers with hard polymer coating (such as PBT) on the edge threads. The composite material integrates the tensile strength of nylon with the abrasion and cut resistance of the hard polymer, simultaneously achieving both load-bearing capability and edge durability.
2Object-affected harmful factors
If the webbing edges are reinforced with hard polymer coating, then the resistance to cutting and fraying is enhanced, but the webbing structure becomes more complex
Solution Approach 1:
The patent segments the webbing into distinct functional zones: uncoated core threads for flexibility and load-bearing, and hard polymer-coated edge threads for protection. This segmentation allows each zone to perform its specific function optimally while maintaining overall structural integrity through the weaving pattern.
Solution Approach 2:
The patent changes the physical parameters of the edge threads by applying hard polymer coating, which alters the surface hardness and friction characteristics. This parameter change enables the edge threads to resist cutting and fraying while the uncoated core threads maintain their flexibility and elasticity.
3Reliability
If the hard polymer coating is applied thickly to maximize protection, then the durability is improved, but the webbing thickness increases and may affect flexibility
Solution Approach 1:
The hard polymer coating is applied locally only to the edge portions of the webbing where cutting and fraying risks exist, rather than coating the entire webbing. This localized application provides maximum protection at critical areas while preserving the flexibility and lightweight characteristics of the uncoated core webbing.
Solution Approach 2:
The patent applies hard polymer coating partially only to the edge threads rather than uniformly to all threads. This partial action provides sufficient protection against edge damage while avoiding excessive coating that would compromise the overall flexibility and handling of the webbing.
