Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in accurately identifying the cause of errors in apparatuses, particularly when multiple factors contribute to the error, and they require significant time and processing to extract relevant information from operation and error history.
Innovation Solution
A recording apparatus and system that acquires and records apparatus information and error signals before and after an error occurs, utilizing a machine-learning model to estimate the error cause based on a combination of apparatus information, including a holding information indicating section to specify the data to be recorded and a machine-learning model to output a score indicating the possibility of error causes.

Engineering Contradiction Analysis
1Reliability
If operation history information and error history information continue to be recorded in the history file at all times, then the complete error history can be maintained, but it needs time and processing ability to extract only the necessary error history information
Solution Approach 1:
The system performs preliminary actions by continuously recording apparatus information in a holding buffer before errors occur. When an error is detected, the buffer already contains the necessary contextual information, eliminating the need to search through extensive historical logs and significantly reducing extraction time while maintaining complete error history.
Solution Approach 2:
The system segments the continuous operation history into discrete error-related segments by using the holding buffer to capture only the apparatus information surrounding error events. This segmentation isolates relevant data from the broader history, making extraction faster and more efficient while preserving complete error context.
2Measurement precision
If error type is recorded as the error history information, then the error can be identified, but in the case of an error caused by a plurality of causes, it is difficult to estimate the cause from the error type
Solution Approach 1:
The system adds another dimension to error analysis by recording not only the error type but also the apparatus information (operational parameters, environmental conditions, recent operations) in the holding buffer. This dimensional expansion transforms simple error type identification into multi-factorial error cause estimation, enabling accurate identification even when multiple causes are involved.
Solution Approach 2:
The holding buffer acts as an intermediary that captures and stores apparatus information contextually surrounding error events. This intermediary layer provides the additional data dimension needed to analyze complex error causes, bridging the gap between simple error type recording and comprehensive error cause estimation.
3Reliability
If the information immediately before the apparatus error occurs cannot be acquired, then the error can be detected, but it is difficult to estimate the cause of the error
Solution Approach 1:
The system performs preliminary action by continuously storing apparatus information in the holding buffer before errors occur. This ensures that the information immediately preceding an error is already captured and available for analysis, enabling accurate error cause estimation while maintaining reliable error detection.
Solution Approach 2:
The system implements feedback by continuously monitoring apparatus information and updating the holding buffer in real-time. This feedback mechanism ensures that the most recent operational context is always available when an error occurs, providing both detection capability and causal analysis information.
