Single-Piece Cargo Net with Ratchet Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo netting systems are complex, difficult to deploy, and inefficient due to multiple interrelated nets requiring specific orientation and lack of mechanical advantage for tight corner compression, leading to significant time and effort losses, particularly in time-sensitive military operations.
Innovation Solution
A single-piece cargo net system with a center section and storage bags for easy orientation, featuring adjustable vertical and horizontal straps with ratchets for secure tightening, allowing quick and efficient deployment and securing of cargo on non-square platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple interrelated nets are used to secure cargo, then the cargo can be securely fastened, but the system becomes complex and difficult to deploy
Solution Approach 1:
The patent combines multiple separate nets (side nets and top net) into a single integrated net structure with interconnected straps and attachment points. This single net design maintains the cargo securing functionality while eliminating the complexity of assembling and orienting multiple separate nets, directly resolving the contradiction between reliability and device complexity.
2Reliability
If multiple nets with specific orientation requirements are used, then cargo can be secured properly, but deployment time increases significantly
Solution Approach 1:
The patent employs asymmetric design elements including a non-square net configuration with distinct long and short sides, and asymmetric attachment point placements that naturally guide correct orientation during deployment. This asymmetric design eliminates the need for complex orientation procedures while maintaining proper cargo securing, resolving the contradiction between reliability and time loss.
3Ease of operation
If standard webbing attachments are used without mechanical advantage, then the system is simple, but corner compression is insufficient
Solution Approach 1:
The patent incorporates dynamic elements including adjustable straps with ratchet mechanisms and movable attachment points that allow the net to adapt to cargo dimensions and apply progressive compression force. This dynamic design enables strong corner compression while maintaining ease of operation through simple adjustment mechanisms, resolving the contradiction between ease of operation and strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system simplifies deployment and securing of cargo by providing a straightforward orientation mechanism and mechanical advantage for tight corner compression, significantly reducing setup time and effort while accommodating various cargo sizes and platform shapes.
Implementation Method 1
many prior art systems don't allow for the load to be tightly compressed on the corners because the attachments utilized on the webbing ends have little or no mechanical advantage
