Pivotable Trailer Bracing Device for Rear-Loading Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inline hay trailers experience jerking and sliding during the loading process, causing transmission damage and making it difficult to load bales, especially on wet or muddy terrain, as conventional methods like wheel chocks and jackknifing are ineffective.
Innovation Solution
A bracing device with pivotable legs that extend forward of the wheels, featuring a beveled foot and pad to dig into the ground, preventing forward movement by securing the trailer during loading, and a locking rod to maintain the legs in position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wheel chocks are used to prevent trailer movement during loading, then the trailer should be stabilized, but the chocks are ineffective as trailers roll right over them due to the heavy weight and force of the bales
Solution Approach 1:
The bracing device transitions from a static position (legs retracted) to a dynamic bracing position (legs extended and angled) during loading. The legs are designed to be movable between positions, allowing the device to adapt to the loading condition and provide effective ground engagement when needed, while not interfering with trailer movement during transport.
Solution Approach 2:
Instead of using horizontal wheel chocks that fail, the invention introduces a vertical dimension by having the legs extend downward at an acute angle to dig into the ground. This dimensional change allows the bracing device to engage the ground effectively against the horizontal pushing force of the loader, converting the stabilization mechanism from a horizontal barrier to a vertical anchor.
2Object-affected harmful factors
If the trailer is braced to prevent forward movement during loading, then transmission damage is prevented, but the bracing device must be strong enough to resist the force of the loader pushing bales
Solution Approach 1:
The bracing device is positioned and activated before the loading process begins. The legs are extended and secured in the bracing position prior to the loader pushing bales onto the trailer, ensuring that the stabilization mechanism is already in place to prevent transmission damage from the outset.
Solution Approach 2:
The bracing device combines multiple structural elements (legs, feet, braces, locking mechanisms) into a unified system that works together to resist the loader's pushing force. The legs work in conjunction with the trailer frame and braking system to create a comprehensive stabilization solution that prevents transmission damage while withstanding the heavy forces involved.
3Reliability
If the legs are extended to brace the trailer, then stabilization is achieved, but the legs must be positioned at an acute angle to effectively dig into the ground
Solution Approach 1:
The legs are designed with the capability to change their angular position, transitioning from a retracted state to an extended state at an acute angle relative to the ground. This dynamic positioning allows the legs to effectively dig into the ground for stabilization while maintaining a compact configuration during transport, achieving reliable stabilization without permanent structural complexity.
