Center Gate Latch With Arcuate Track for Livestock Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Livestock trailers lack an effective mechanism to secure the center gate, allowing resisting animals to overpower workers and potentially cause injury or death during loading.
Innovation Solution
A spring-biased safety latch mechanism with a post and arcuate track system that allows the center gate to be locked in multiple angular positions, preventing animals from moving the gate by using a lifting lever to secure the post into segregated compartments along the track.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the center gate is made freely movable with little resistance to facilitate easy opening, then the ease of operation is improved, but the safety and control over the gate deteriorates, allowing animals to overpower workers
Solution Approach 1:
The gate system transitions from a static fixed-gate design to a dynamic system where the gate can be selectively positioned and locked at multiple locations along an arcuate track, allowing the operator to adjust the gate's position and security level based on operational needs
Solution Approach 2:
The continuous arcuate track is segmented into multiple discrete compartments, each providing a distinct locking position. This segmentation allows the gate to be secured at various angular positions, creating intermediate states between fully open and fully closed positions
2Reliability
If the center gate is secured in a fixed position to prevent animal movement, then the safety and control are improved, but the ease of operation deteriorates, requiring additional steps to open or close the gate
Solution Approach 1:
The spring-biased post is preliminarily positioned within one of the track compartments, maintaining automatic engagement with the lifting lever. This preliminary positioning eliminates the need for manual intervention to maintain gate security during normal operation
Solution Approach 2:
The spring mechanism automatically maintains the post in engagement with the lifting lever, providing self-servicing security without requiring continuous manual attention. The system self-regulates to maintain gate position and security
3Device complexity
If a simple latch mechanism is used to minimize device complexity, then the ease of manufacture and device complexity are improved, but the reliability and safety deteriorate, insufficient to withstand animal force
Solution Approach 1:
The spring-biased post acts as a counterweight mechanism, using spring force to resist and balance the substantial force exerted by animals on the gate. This mechanical counterbalancing provides reliable security without complex active control systems
Solution Approach 2:
The lifting lever and locking mechanism are merged into a single integrated component that performs both the lifting and securing functions simultaneously, eliminating the need for separate locking devices while maintaining robust security
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 solution effectively secures the center gate, preventing livestock from forcing it open and ensuring safer loading operations by allowing the gate to be locked in various positions, thereby reducing the risk of injury to workers.

AI summary
A safety latch mechanism for anchoring an open center gate in a livestock trailer includes a spring-biased post attached to the center gate's free edge having a lifting lever at an upper end. An arcuate track embedded within the truck bed traces the path of the center gate's free edge when moving between a fully opened and a fully closed position. The track includes a series of juxtaposed, segregated compartments for receiving a lower end of the post. Accordingly, the center gate can be locked in a multitude of angular positions between the fully open and fully closed positions by lifting the lever and releasing it into one of the compartments.
