Container Load Securement Wings for Easy Corner-Post Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shipping containers often have voids that allow goods to shift during transit, leading to collisions and damage, and existing load-securement devices are cumbersome or inefficient for securing loads.
Innovation Solution
A load-securement device with movable wings that can transition between compact and securement configurations, allowing easy attachment to shipping container corner posts and securement using flexible straps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing load-securement devices are used, then loads can be secured, but the devices are cumbersome and difficult to attach to corner posts
Solution Approach 1:
The load-securement device incorporates movable wings that can transition between a compact configuration for insertion and an expanded configuration for securing. This dynamic transformation allows the device to be easily attached to corner posts while maintaining securement capability, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The device features a compact configuration where the wings are nested or folded together, allowing the entire device to fit within the receiving channel of the corner post. This nesting principle enables easy attachment and storage while providing full securement functionality when deployed.
2Reliability
If loads are secured with traditional methods, then goods can be restrained, but voids remain unminimized leading to shifting and damage
Solution Approach 1:
The device uses multiple wings that can independently engage with the load and the corner post structure. This segmentation allows the device to secure the load from multiple directions simultaneously, minimizing voids and preventing shifting more effectively than single-point securement methods.
Solution Approach 2:
The corner-engaging ends of the wings are specifically designed to interface with the corner post receiving channel, providing localized securement at critical corner points. This local quality approach ensures that the most vulnerable areas of the load (near corners) receive enhanced securement, preventing collision damage.

AI summary
Various embodiments of the present disclosure provide load-securement devices and processes for securing loads in a shipping container. Generally, each load-securement device includes a base and two wings each having a corner-engaging end. The wings are attached to the base and are movable relative to one another and to the base from a compact configuration in which a first distance separates the corner-engaging ends to a securement configuration in which a second greater distance separates the corner-engaging ends. Since the load-securement device is more compact when the wings are in the compact configuration (as compared to the securement configuration), it is easier to attach to a shipping container—and particularly to a front corner post of the shipping container—as compared to a similar load-securement device that has immovable wings fixed in the securement configuration.
