Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current measurement devices lack flexibility in grasping the operational state and forecasting faults due to limited error log data, which can lead to missed error messages and inefficient maintenance, especially in systems with low error frequency.
Innovation Solution
A measurement device and system that generate and record various driving information, including probe usage data, collision counts, and electric-conduction time, allowing for detailed analysis of the operational state and enabling proactive maintenance by associating this information with identification data of probes and styluses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If error messages are temporarily displayed on display means, then error information is provided to users, but error messages are erased after predetermined time elapses making it difficult to investigate past errors
Solution Approach 1:
The system performs preliminary action by automatically recording error messages, error logs, and operational data in storage memory before they are needed for investigation. This allows error information to be preserved indefinitely without requiring continuous display, enabling retrospective analysis at any time.
Solution Approach 2:
The system creates a copy of error information and operational data from the temporary display buffer and stores it in persistent storage memory. This copying mechanism ensures that error messages are not lost when displayed temporarily, and can be retrieved later for investigation without re-occurrence of the original error.
2Adaptability or versatility
If only accumulated data of specific parts is recorded, then data storage is simplified, but data items are limited reducing flexibility in grasping operational state and forecasting faults
Solution Approach 1:
The control section is designed with multi-functionality to perform diverse data acquisition tasks. It can record not only accumulated operational data but also instantaneous values, error logs, alarm information, and environmental conditions from multiple sensors, making the system adaptable to various analysis needs without requiring separate specialized systems.
Solution Approach 2:
The data recording system is made dynamic by allowing flexible configuration of recording parameters. The control section can adaptively select which data items to record based on operational mode, error types, and user preferences, enabling the system to optimize between data comprehensiveness and storage requirements according to specific needs.
3Measurement precision
If comprehensive driving information is recorded for all probes, then probe consumption analysis is improved, but data storage and processing requirements increase
Solution Approach 1:
The system applies local quality by selectively recording comprehensive driving information only for probes that are currently attached and actively used, while using simpler identification data for probes that are not in use. This differentiated approach ensures accurate analysis for relevant probes without unnecessarily storing data for all probes in the system.
Solution Approach 2:
The system implements partial action by recording detailed driving information at selective intervals rather than continuously for all probes. It captures essential usage patterns and consumption metrics at meaningful time points, providing sufficient data for accurate analysis while avoiding excessive data accumulation that would occur with continuous full-resolution recording.
