Adjustable Cargo Strap With Dual Buckles for Odd-Shaped Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo securing methods struggle to effectively secure odd-shaped cargo in open areas, such as truck beds, without using multiple straps or improvised solutions like stacking objects or using tarps.
Innovation Solution
An adjustable cargo strap with hook latches and cam buckles, featuring pass-through connectors that allow for the creation of one or two cargo areas, enabling securement of odd-shaped cargo by wrapping around the cargo and tightening with cam buckles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cargo straps or improvised solutions are used to secure odd-shaped cargo, then cargo security is improved, but device complexity increases
Solution Approach 1:
The cargo strap is divided into multiple segments including first and second cam buckles, first and second hook latches, and pass-through connectors that can be independently adjusted. This segmentation allows each component to perform its specific function while collectively providing secure fastening of odd-shaped cargo without requiring multiple separate straps.
Solution Approach 2:
The adjustable cargo strap is designed as a multi-functional device that can secure various types of cargo including odd-shaped objects like coolers, gas cans, and propane tanks. The strap can be configured in different patterns (crisscross, parallel, or single strap) depending on the cargo shape and size, making it a universal solution that replaces multiple specialized straps.
2Reliability
If existing tie-down straps are used to hold odd-shaped objects against hard surfaces, then cargo security is improved, but ease of operation worsens due to difficulty in securing odd-shaped objects
Solution Approach 1:
The cargo strap incorporates adjustable cam buckles and pass-through connectors that allow dynamic reconfiguration of the strap length and configuration. Users can easily adjust the strap to wrap around odd-shaped cargo in various patterns, making the securing process simple and adaptable to different cargo shapes without requiring complex manual manipulation.
Solution Approach 2:
The pass-through connectors act as intermediaries between the cam buckles and hook latches, allowing the strap to be easily routed and adjusted around odd-shaped cargo. These connectors provide friction-based grip that maintains tension while allowing simple adjustment, mediating between the user's pulling action and the final secured state.
3Device complexity
If a single cargo strap is used without pass-through connectors, then device complexity is reduced, but adaptability to different cargo shapes and sizes decreases
Solution Approach 1:
The strap is segmented into adjustable sections created by pass-through connectors positioned at different locations along the strap length. This segmentation allows independent adjustment of each section to accommodate different cargo dimensions and shapes while maintaining a relatively simple overall strap structure.
Solution Approach 2:
The pass-through connectors enable dynamic reconfiguration of the strap by allowing the webbing to be routed through different connector combinations. This creates variable effective lengths and wrapping patterns that adapt to different cargo shapes and sizes without requiring multiple different strap designs.
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
The adjustable cargo strap provides a secure and efficient way to strap down odd-shaped objects, allowing for flexible configuration to fit various cargo shapes and sizes, thereby enhancing cargo security and stability during transport.
Implementation Method 1
cam buckles for tensioning the strap located proximate to both ends
Data Source
AI summary
The present invention relates to an adjustable cargo strap configured with hook latches at both ends and cam buckles for tensioning the strap proximate to both ends. A series of pass-through connectors configure lengths of straps that run between the cam buckles forming one or two cargo areas where one or both cargo areas can be used to secure odd-shaped cargo easily. In operation, a user can secure the hook latches between the opening of a truck bed, or other span or opening. Cargo can be placed in the cargo areas. The loose ends of the cam buckle straps can be pulled to remove any slack in the straps. Each of the cam buckles can then be adjusted in ratchet or pull-and-grip style by the user to increase the force on the strap causing the cargo areas to be constricted around and secure the cargo.
