Sword Beam Load Securing for Commercial Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load securing arrangements for commercial vehicles are inefficient in securing loads against lateral movement during cornering and are complex, especially when transporting pallets, as they require additional installations and take up storage space.
Innovation Solution
The introduction of sword beams parallel to the travel direction, which can be fixed to transverse beams and have recesses to fit around crossbeams, allowing for secure fastening of lashing straps and preventing lateral movement by matching the cargo form, with adjustable fastening to accommodate different distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beams aligned transversely to the direction of travel are used with lashing straps, then loads can be secured against longitudinal movement, but loads are not effectively secured against lateral movement during cornering and additional installations are required
Solution Approach 1:
The patent introduces sword beams that extend in the longitudinal direction (parallel to travel direction) to complement the transverse beams. This adds a new dimensional element for load securing, enabling lateral restraint through the longitudinal orientation of the sword beams while maintaining compatibility with existing transverse beam structures.
Solution Approach 2:
The sword beams are designed to work in conjunction with both the transverse beams and the mounting rails, creating a multi-functional load securing system. The same mounting rail infrastructure serves both transverse and longitudinal securing functions, eliminating the need for separate dedicated lateral securing installations.
2Reliability
If clamping hooks with threads are used to brace the frame, then cylindrical cargo can be secured, but the arrangement becomes very complex and builds extremely high
Solution Approach 1:
The patent extracts the complex threaded clamping mechanism from the load securing system and replaces it with simple hook-shaped fastening elements that engage with holes in the mounting rails. This simplifies the overall arrangement by removing unnecessary mechanical complexity while maintaining securing effectiveness.
Solution Approach 2:
Instead of using active clamping mechanisms that require threading and tightening operations, the patent employs passive hook-shaped fasteners that simply engage with pre-drilled holes. This inverts the approach from active mechanical fastening to passive geometric interlocking, significantly reducing complexity.
3Ease of operation
If beams are fixed at fixed positions on mounting rails, then load securing is simplified, but flexibility in positioning for different cargo configurations is reduced
Solution Approach 1:
The mounting rails are designed with multiple holes at different positions along their length, allowing the beams to be dynamically repositioned according to cargo requirements. The fastening means can engage with different holes to accommodate varying cargo configurations, providing both ease of operation and positioning flexibility.
