Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply grounding fault protection circuits require manual resetting after a GFCI has been tripped, which can be inconvenient if the operator is not present, lacking remote resetting capabilities.
Innovation Solution
Incorporating a wireless network circuit and an automatic resetting circuit into the power supply grounding fault protection circuit, allowing for remote control and automatic resetting of the GFCI through a wireless network, enabling users to remotely reset the device after a fault is cleared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual resetting is used after GFCI tripping, then the device can be reset, but it requires operator presence and manual intervention which is inconvenient when the operator is away
Solution Approach 1:
The system automatically detects when the leakage fault has been eliminated and autonomously resets the GFCI without requiring manual intervention. The microcontroller monitors the leakage current continuously and automatically closes the tripping mechanism control circuit when normal operation is detected, enabling the device to serve itself.
Solution Approach 2:
The system continuously monitors leakage current through the leakage grounding detection circuit and uses this feedback information to determine when to reset. The microcontroller receives real-time feedback on circuit status and automatically resets when the feedback indicates the fault has been cleared, creating a closed-loop control system.
2Adaptability or versatility
If manual resetting is required, then the control logic is simple, but remote resetting capability is lost
Solution Approach 1:
The microcontroller serves multiple functions: it monitors leakage current, controls the tripping mechanism, receives wireless commands, and performs automatic resetting. By making the control system multi-functional, the patent adds remote resetting capability without requiring a completely separate control system.
Solution Approach 2:
The wireless communication module acts as an intermediary between the user and the GFCI system. It receives remote reset commands and transmits them to the microcontroller, which then executes the reset operation, allowing remote control without direct physical interaction with the device.
