Electric Strand Gate With Automated Vertical Hoisting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric fencing gates with electric strands are inconvenient to open and close, particularly for vehicles and livestock, due to the need for manual operation or swing gates.
Innovation Solution
An electric strand gate with an actuator that automatically hoists electric strands along a hoisting rail from a closed to an open position, providing clearance for passage and allowing remote control, with shuttles connected to each strand, and the ability to adjust height and spacing for different vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation or swing gates are used for electric fencing gates, then the gate structure is simple, but the ease of operation deteriorates due to inconvenience for vehicles and livestock
Solution Approach 1:
The patent replaces manual mechanical operation with an automated actuator system that uses electric motors to hoist the electric strands vertically along guide rails. This substitution eliminates the need for manual handling while maintaining gate functionality, directly resolving the contradiction between ease of operation and device complexity by automating the previously manual process.
Solution Approach 2:
The patent employs dynamic positioning of electric strands through vertical movement along guide rails, allowing the gate to transition between closed and open positions automatically. This dynamic system replaces static swing gate mechanisms, improving operational convenience for vehicles and livestock while the automation manages the increased complexity through programmed control sequences.
2Length of moving object
If electric strands are moved vertically to provide clearance, then the clearance for passage is improved, but the device complexity increases due to hoisting mechanism
Solution Approach 1:
The patent divides the electric fence into multiple independent electric strands that can be individually hoisted and controlled. Each strand is attached to separate shuttles that travel along guide rails, allowing selective vertical positioning. This segmentation enables clearance adjustment without moving the entire fence structure, managing complexity through modular, independent control of each strand.
Solution Approach 2:
The patent introduces shuttles as intermediary components that travel along guide rails and attach to electric strands. These shuttles serve as mediators between the hoisting mechanism and the electric strands, enabling vertical movement while maintaining electrical continuity and facilitating controlled positioning without direct mechanical connection between the motor and each strand.
3Object-affected harmful factors
If electric strands are disconnected in open position, then the safety is improved, but the reliability of fence integrity deteriorates
Solution Approach 1:
The patent implements periodic electrical disconnection and reconnection of the electric strands through the gate. The strands are electrified during the closed position to maintain fencing function, and temporarily disconnected during the open position for safety. This periodic action cycle ensures both safety during passage and reliability of fence integrity when closed, with the control system managing the timing and sequencing of electrical connection states.

AI summary
An electric strand gate has at least one electric strand thereacross. The gate comprises an actuator which moves the electric strand up along a hoisting rail from a closed position to an open position, thereby providing clearance thereunderneath for passage of livestock, vehicles and or the like through the gate. The gate may have shuttles travelling along the hoisting rail, each of which is connected to a respective electric strand. The rail and shuttles may be configured so that electric strands are closer together when in the open position, thereby maximising clearance thereunderneath whilst moving apart in the closed position, so as to maintain the full height of the electric fence. The shuttles and the rail may be further configured so that the electric strands are electrically disconnected in the open position.
