Arc Elimination Handle Reset Using Actuator and Moving Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arc elimination devices require direct user contact to return the handle to its original position, posing safety risks and risking damage to components when the high-voltage electrode and ground electrode are connected.
Innovation Solution
An arc elimination device with a moving plate that uses an actuator to press and move the handle, allowing remote operation without direct user contact, and a power transmission unit to control the movement, preventing excessive handle extension and component damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user directly touches and operates the movable electrode connected to the high-voltage electrode and handle, then the arc eliminator can be operated to return to open state, but safety problems arise due to electrical connection between high-voltage electrode and ground electrode
Solution Approach 1:
The patent introduces a moving plate as an intermediary component between the user's hand and the handle. The moving plate is driven by an actuator to push the handle back to its initial position, allowing the user to operate the arc eliminator remotely without directly touching the handle or moving electrode during the high-voltage connected state, thus eliminating the safety risk while maintaining operational ease
2Ease of operation
If the handle is pulled out excessively to return to original position, then remote operation is achieved, but damage to other components may occur
Solution Approach 1:
The patent employs a feedback mechanism using a switch that detects when the handle reaches its initial position. When the handle returns to the correct position, the switch is activated to automatically stop the actuator's driving force. This feedback control prevents the handle from being pulled out excessively, ensuring remote operation is achieved while protecting components from damage due to over-travel
