Multi-Member Hinge for 360-Degree Gate Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Livestock, especially heavy domesticated animals with poor depth perception, can unintentionally trample through partially opened gates due to their tendency to crowd and push back, posing a risk of injury and escape.
Innovation Solution
A hinge system comprising multiple hinge members and crossbars that allow the gate to swing 360 degrees, enabling it to rotate inward or outward from the fence, thereby preventing the gate from being pushed back into the gateway and allowing for safe passage of animals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional fixed gate hinge is used, then the gate remains stable and secure, but the gate cannot swing freely to prevent animals from pushing it back into the gateway
Solution Approach 1:
The hinge system transitions from a fixed, static connection to a dynamic, multi-directional pivoting mechanism. The gate can swing approximately 360 degrees around the post, allowing it to move inward or outward as needed to prevent animals from pushing it back into the gateway while maintaining secure attachment when closed
2Object-affected harmful factors
If the gate is allowed to swing freely to prevent animal trampling, then safety improves, but the hinge structure becomes more complex
Solution Approach 1:
The hinge is divided into multiple independent components: a first hinge member attached to the post, a second hinge member attached to the gate, and crossbars connecting them. This segmentation allows each component to perform a specific function while maintaining overall structural integrity and enabling the 360-degree swing capability
Solution Approach 2:
The hinge members and crossbars are nested together to form an integrated pivoting system. The crossbars connect the hinge members in a nested configuration that allows rotational movement while maintaining structural coherence, achieving safety without excessive complexity

AI summary
A hinge permitting a gate to rotate approximately 180 degrees in either direction. The hinge includes first, second, third, and fourth hinge members and first, second, third, and fourth crossbars. The first, second, third, and fourth crossbars form an interpivoting connection with the first, second, third, and fourth hinge members.
