Load Restraint Strip Bracing for Cargo Container Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load restraint systems for cargo containers face challenges in maintaining adhesive bonds under increased forces during transport, leading to potential peeling of restraint strips from the container walls, which can result in inadequate cargo security and increased loading times due to the need for multiple strips.
Innovation Solution
Incorporating braces between the cargo and load restraint strips to exert reactive outward pressure, maintaining contact between the affixing region of the strips and the container walls, thereby enhancing the adhesive bond strength and reducing peeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple restraining strips are used to secure cargo, then cargo security is improved, but loading time and device complexity increase
Solution Approach 1:
The patent combines multiple restraining strips into a single integrated strip system that provides equivalent or superior cargo security. The load restraint strip is designed with specific structural features (reinforcement layers, adhesive regions) that allow one strip to perform the function of multiple traditional strips, thereby reducing loading time while maintaining reliability
2Force
If restraining strips are subjected to increased forces during transport, then cargo restraint capability is improved, but adhesive bond strength deteriorates due to peeling
Solution Approach 1:
The load restraint strip is constructed as a composite structure with multiple layers including a base layer, reinforcement layers (woven or non-woven), and adhesive regions. This composite design distributes the applied forces across different structural elements, preventing the adhesive bond from bearing the full restraint force and thereby maintaining bond strength even under high force conditions
Solution Approach 2:
The strip design incorporates localized reinforcement at critical stress points, particularly at the adhesive regions where forces are applied. The reinforcement layers are strategically positioned to provide additional strength exactly where needed to prevent peeling, while other portions of the strip maintain appropriate flexibility and adhesion properties
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
This solution strengthens the load restraint system, allowing for fewer and potentially stronger strips to be used, reducing the risk of peeling and improving loading efficiency by minimizing the number of strips required.
Implementation Method 1
Each strip 106 is flexible and has an adhesive-coated end 107. An end 107a of a first strip 106a is pressed against an interior surface of side wall 102L.

AI summary
Systems and methods for securing cargo within a cargo container are described. The cargo is loaded within an interior of the container and one or more load restraint strips may be used to secure the cargo. Each load restraint strip may include an affixing region having an adhesive for securing the strip to a wall of the container. One or more braces may be inserted between the cargo and the load restraint strips.
