Securement Hook Asymmetric Geometry for Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Poorly secured loads result in a significant number of crashes and fatalities each year, highlighting the need for improved load securing mechanisms.
Innovation Solution
The Securement Hook is designed to engage with the end of a loading strap, providing enhanced convenience and safety by attaching to or surrounding loads, utilizing a unique geometry and materials like non-heat tempered steel for secure engagement with various strap ends and D-rings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional strap securing methods are used, then the device complexity is low, but the reliability of load securing is insufficient leading to crashes and fatalities
Solution Approach 1:
The patent introduces an intermediary component (the securement hook with engagement features) between the strap and the load to improve securing reliability. This hook acts as a mediator that provides positive engagement and prevents strap slippage, thereby enhancing the overall securing system's reliability without requiring a complete redesign of the strap itself.
Solution Approach 2:
The securing system is segmented into distinct functional components: the strap, the securement hook, and the engagement features. This segmentation allows each component to be optimized independently - the hook can be designed specifically for reliable engagement while the strap maintains its simple tensioning function, resolving the contradiction between reliability and complexity.
2Adaptability or versatility
If a securement hook with complex geometry is used to engage various strap ends, then the adaptability improves, but the ease of manufacture decreases
Solution Approach 1:
The securement hook is designed with universal engagement features that can interface with multiple types of strap ends (buckles, D-rings, hooks, etc.). This multi-functionality allows a single hook design to work across different strap types and securing systems, achieving high adaptability without requiring multiple specialized components.
Solution Approach 2:
The hook employs asymmetric geometry with specific engagement surfaces and profiles that can accommodate various strap end configurations. The asymmetric design allows the same hook to engage different strap types through rotational or positional adjustment, providing versatility while maintaining a single manufacturable component design.
3Strength
If high-strength materials like non-heat tempered steel are used, then the strength increases to 3200 lbs breaking point, but the weight increases
Solution Approach 1:
The patent specifies using non-heat tempered steel with a minimum yield strength of 3200 lbs, representing a parameter change in material selection to achieve the required strength. This material parameter change ensures the hook can withstand high loads while the design optimizes the balance between strength and weight by selecting appropriate material grades and thicknesses.
