Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face difficulties in quickly and timely determining if a fuse has blown and which fuse needs to be replaced in industrial control apparatuses, leading to cumbersome troubleshooting and potential delays in replacement.
Innovation Solution
An industrial control apparatus with a detection assembly that sends a detection signal when a fuse is blown, comprising resistive devices and an isolation device, coupled with a processing device to output identification and position information, and a human-machine interface to alert operators through characters, graphics, or sound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If operators manually check indicator lights in field facilities to determine fuse status, then they can obtain fuse information, but the troubleshooting process becomes cumbersome and time-consuming
Solution Approach 1:
The patent implements automatic feedback mechanisms where the control apparatus continuously monitors fuse status through detection assemblies and immediately communicates blown fuse information to operators via display interfaces, eliminating the need for manual field checking and significantly reducing troubleshooting time
Solution Approach 2:
The system performs self-monitoring of fuse status through integrated detection assemblies that automatically detect and report blown fuses without requiring operator intervention, enabling the apparatus to service itself by providing real-time fault information
2Productivity
If operators need to physically go to cabinet facilities to check indicator lights, then they can identify blown fuses, but the operation becomes complex and inefficient
Solution Approach 1:
The patent introduces detection assemblies as intermediary components that mediate between the fuse and the operator, automatically detecting fuse status and transmitting this information through the control system to display interfaces, thereby eliminating the need for operators to physically inspect indicator lights and improving productivity
Solution Approach 2:
The system replaces manual mechanical inspection of indicator lights with automated electrical detection mechanisms that electronically monitor fuse status and communicate information through the control system, substituting physical field checking with automated electronic monitoring to improve efficiency
