Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual worker dispatch is used to identify failed parts, then measurement precision can be improved, but loss of time and labor costs increase
Solution Approach 1:
The system enables self-service by having the alarm generation devices automatically provide failure location information through the estimation device, eliminating the need for manual worker dispatch. The estimation device processes alarm data autonomously to identify failed parts, allowing the system to serve itself rather than requiring human intervention for initial diagnosis.
Solution Approach 2:
The patent replaces the mechanical system of manual worker dispatch with an automated information processing system. Instead of physically sending workers to locate failures, the system uses computational algorithms to analyze alarm data and automatically determine failure locations, substituting mechanical human action with automated digital processing.
2Reliability
If alarm history is viewed going back in time, then reliability of failure determination improves, but loss of time increases
Solution Approach 1:
The system performs preliminary action by pre-configuring the estimation device with failure determination algorithms and alarm data structures before actual failures occur. The device is prepared in advance to process alarm histories efficiently, so when failures happen, the system can immediately begin analysis without time-consuming setup or configuration delays.
Solution Approach 2:
The patent applies skipping by enabling the estimation device to rapidly process through alarm histories and identify failure locations without examining every detail sequentially. The system uses intelligent algorithms that can quickly filter and prioritize relevant alarm information, rushing through the analysis process to provide timely results while maintaining high reliability.
3Measurement precision
If skilled operator analyzes alarms to determine failed parts, then measurement precision improves, but device complexity increases
Solution Approach 1:
The system uses copying by creating a virtual replica of the alarm analysis function within the estimation device. Instead of requiring complex manual analysis procedures, the device contains a simplified digital model that replicates the analytical capability, making the system easier to operate while maintaining precision through consistent, repeatable computational logic.
