Industrial Machine Recovery Process Automation for Abnormality Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems require significant manual effort and time for recovery from abnormalities in industrial machines, as users need to manually specify and execute recovery processes, which is inefficient and labor-intensive.
Innovation Solution
A production system that includes a circuitry to detect abnormalities, receive specifications for recovery processes, and record recovery process information, allowing for automated execution of recovery procedures based on previously specified processes when abnormalities occur again.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual recovery processes are used for industrial machine abnormalities, then users can handle abnormalities, but the time and effort required for recovery is excessive
Solution Approach 1:
The system performs preliminary action by automatically determining and executing recovery processes based on detected abnormality types. When an abnormality occurs, the determination circuitry immediately identifies the appropriate recovery process from stored process information and executes it automatically, eliminating the time-consuming manual specification steps that currently require user intervention.
2Ease of operation
If manual specification of recovery processes is required, then users can control the recovery steps, but the operation becomes labor-intensive and inefficient
Solution Approach 1:
The system implements self-service by automatically determining and executing recovery processes without requiring user specification. The determination circuitry autonomously selects appropriate recovery processes based on the detected abnormality type and executes them through the execution circuitry, allowing the system to service itself during abnormality recovery operations.
Solution Approach 2:
The system uses feedback mechanisms where the detection circuitry continuously monitors industrial machine operations, identifies abnormality types, and feeds this information back to the determination circuitry which then selects appropriate recovery processes. This closed-loop feedback system enables automatic adaptation and execution of correct recovery procedures without manual intervention.
3Productivity
If automated recovery execution is implemented, then recovery speed increases, but the system complexity increases due to additional circuitry requirements
Solution Approach 1:
The system achieves multi-functionality by integrating determination circuitry and execution circuitry that can handle multiple abnormality types and their corresponding recovery processes within a single automated framework. The determination circuitry stores and manages process information for various abnormality types, enabling the system to universally apply appropriate recovery procedures across different failure modes without requiring separate manual control systems for each case.
