Wall Securement Device Protrusion for Cargo Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo securing methods in ocean shipping containers are inefficient, particularly in preventing load shifting and do not meet international regulatory standards, leading to potential safety issues and increased costs.
Innovation Solution
A wall securement device with a protrusion on its rear main surface, designed to attach to container corner posts, enhances ease of application and stability by transferring pulling forces effectively, allowing for secure lashing of heavy loads without hindering cargo space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lashing points (D-rings) are used to secure cargo, then cargo can be secured against shifting, but the application process is time-consuming and complex
Solution Approach 1:
The wall securement device is divided into multiple leaves (at least two leaves with front and rear main surfaces), each capable of independently receiving straps through apertures. This segmentation allows for easier installation and adjustment while maintaining securement reliability.
Solution Approach 2:
The protrusion on the rear main surface automatically engages with the corner post structure to provide self-positioning and self-locking functionality. The device self-adjusts to the corner post geometry, eliminating the need for complex alignment procedures during installation.
2Stability of the object's composition
If multiple lashing and anchor points are used to prevent cargo shifting, then cargo stability improves, but device complexity and installation difficulty increase
Solution Approach 1:
Multiple functional elements (multiple leaves with apertures, protrusion for positioning, and attachment mechanism) are merged into a single integrated wall securement device. This consolidation provides multiple lashing points and stability features while simplifying installation compared to using separate components.
Solution Approach 2:
The device serves multiple functions simultaneously: the leaves provide lashing points for straps, the protrusion provides positioning and locking, and the overall structure attaches to corner posts. This multi-functionality reduces the number of separate devices needed while maintaining cargo stability.
3Reliability
If traditional securement devices are used, then cargo can be lashed, but ease of application and user-friendliness are reduced
Solution Approach 1:
The protrusion on the rear main surface automatically engages with the corner post structure to provide self-positioning and self-locking functionality. The device self-adjusts to the corner post geometry, eliminating the need for complex alignment procedures during installation.
Solution Approach 2:
The protrusion is pre-formed on the rear main surface to match the corner post geometry, so that when the device is approached to the corner post, the protrusion automatically aligns and engages with the corner profile, preparing the device for secure attachment before final tightening.
4Force
If securement devices are designed for heavy loads, then load capacity increases, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The wall securement device is divided into multiple leaves (at least two leaves with front and rear main surfaces), each capable of independently receiving straps through apertures. This segmentation allows for easier installation and adjustment while maintaining securement reliability.
