Container Load Lashing Strap Groups for Even Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load securing systems in containers result in unequal distribution of forces on the load due to varying lash stretch, leading to potential damage and safety hazards during transport.
Innovation Solution
A system comprising groups of lashing straps with varying effective lengths and stiffnesses, secured at specific points within the container to evenly distribute forces across the load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If direct lashing is used with straps of varying lengths, then the lashing system can accommodate different container sizes and load configurations, but the load is not equally supported and forces are unevenly distributed
Solution Approach 1:
The lashing system is divided into multiple independent groups (first group, second group, third group) with different effective lengths. Each group is attached to different lashing points on the container, allowing the system to adapt to various container sizes and load configurations while maintaining equal force distribution within each group.
Solution Approach 2:
Different groups of straps are assigned different effective lengths tailored to specific lashing point configurations. The first group has a first effective length suitable for certain container sections, the second group has a second effective length for other sections, and the third group has a third effective length for additional positioning. This local customization ensures equal force distribution at each lashing location while maintaining overall system adaptability.
2Reliability
If straps are tensioned to secure the load, then the load is restrained from moving, but unequal stretch in lashes results in unequal forces on the load
Solution Approach 1:
The lashing system divides straps into multiple groups with different effective lengths, where each group is tensioned independently at specific lashing points. This segmentation allows each group to exert equal force on the load at its designated location, while the combined effect of all groups provides comprehensive load securing.
Solution Approach 2:
The system changes the parameter of effective length for different strap groups to compensate for varying distances between lashing points and load attachment points. By adjusting the effective length parameter for each group, the system ensures that all straps achieve equal tension and force distribution when tensioned, eliminating unequal force application while maintaining reliable load securing.
