Pivoting Cargo Lashing Elements for Flexible Aircraft Load Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo loading systems in aircraft lack flexibility in arranging diverse cargo loads, particularly with varying weights, and require additional fastening options for passenger seats, leading to inefficiencies in loading time and personnel requirements.
Innovation Solution
A lashing device with pivotable lashing elements, allowing multiple chains or straps to be secured to a single point without exceeding load limits, enhancing flexibility and load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lashing points with single lashing rings are used, then the structure is simple and reliable, but the flexibility in arranging diverse cargo loads is limited
Solution Approach 1:
The single lashing ring is segmented into multiple lashing elements (at least two) that can be independently used or combined. Each lashing element can be individually attached to cargo items, allowing flexible arrangement of diverse loads while maintaining a relatively simple overall structure.
Solution Approach 2:
The lashing device with multiple lashing elements serves multiple functions: it can lash single heavy items using all elements together, or distribute loads across multiple lighter items using individual elements. This multi-functionality increases adaptability without requiring entirely different lashing systems for different cargo configurations.
2Adaptability or versatility
If multiple lashing points are distributed throughout the cargo hold, then cargo arrangement flexibility is improved, but the number of lashing points required increases
Solution Approach 1:
Each lashing device with multiple lashing elements serves as a universal lashing point that can handle various cargo configurations. This reduces the total number of lashing points needed compared to conventional systems that require numerous distributed single-point lashing rings to achieve the same flexibility.
3Adaptability or versatility
If conventional lashing systems are used for diverse cargo weights, then the system is simple, but additional fastening options are required for passenger seats
Solution Approach 1:
The lashing device with multiple independently usable lashing elements provides universal fastening capability that works for both cargo items and passenger seats. The same device structure serves multiple purposes, eliminating the need for separate fastening systems while maintaining relative simplicity.
