Polyester Filament Cargo Restraint for Momentum Force Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo restraint systems for intermodal containers are inefficient, costly, and fail to securely manage momentum forces during transport, particularly for hazardous materials, due to limitations in strength, labor requirements, and compliance with regulations, leading to damage and reduced transport efficiency.
Innovation Solution
A flexible load restraining strip with a polyester filament strand denier content, featuring multiple layers of adhesive and reinforcement, is designed for securement within transport containers, utilizing a combination of adhesives and release materials to efficiently restrain cargo without leaving residues, suitable for various transport modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cargo restraint systems are used, then cargo can be secured, but the systems are inefficient, costly, and fail to securely manage momentum forces during transport
Solution Approach 1:
The patent changes the physical parameters of the restraint system by using high-denier polyester filament strands (9,000 denier) with specific break strength characteristics (15-20 grams per strand) and controlled elongation properties (10-15% elongation at break). These parameter changes enable the material to effectively absorb and dissipate momentum forces during transport while maintaining securement reliability.
Solution Approach 2:
The patent employs composite material construction by combining polyester filament strands woven into fabric with adhesive layers and release paper. This composite structure integrates the strength and elasticity of polyester fibers with the bonding properties of adhesives, creating a restraint system that simultaneously provides secure attachment to cargo and container walls while maintaining flexibility to manage dynamic forces during transport.
2Reliability
If traditional restraint materials are used, then cargo can be restrained, but labor requirements and costs increase
Solution Approach 1:
The restraint system is pre-manufactured with polyester fabric panels having adhesives pre-applied to specific areas and release paper pre-attached to protect the adhesive surfaces. This preliminary preparation eliminates the need for workers to manually apply adhesives or assemble multiple components during cargo loading, significantly reducing labor requirements and deployment complexity while maintaining reliable cargo restraint effectiveness.
