Engineering Contradiction Analysis
1Volume of moving object
If miniaturization is pursued to reduce electronic equipment size, then compactness is improved, but reliability deteriorates due to intrinsic degradation mechanisms
Solution Approach 1:
The patent applies preliminary action by measuring the electromagnetic spectrum emitted by electronic components during accelerated aging tests before actual deployment. This allows the system to pre-characterize components and establish their baseline electromagnetic signatures, enabling future detection of degradation patterns that indicate impending failures. The preliminary measurements create a reference database that facilitates early warning of reliability issues.
Solution Approach 2:
The patent replaces traditional mechanical or electrical testing methods with electromagnetic spectrum analysis. Instead of using physical probes or electrical measurements to monitor component health, the system uses non-contact electromagnetic spectrum measurement to detect changes in component behavior. This substitution enables continuous monitoring without physical interference and provides insights into component degradation mechanisms.
2Measurement precision
If traditional malfunction detection methods are used, then detection capability is maintained, but the ability to anticipate failures deteriorates
Solution Approach 1:
The patent implements feedback by continuously measuring the electromagnetic spectrum emitted by electronic components during operation and comparing these measurements against reference data from accelerated aging tests. When deviations exceed predefined thresholds, the system generates warnings about potential failures. This closed-loop feedback mechanism enables the system to adapt to component degradation patterns and provide early warnings before actual malfunctions occur.
Solution Approach 2:
The patent performs preliminary characterization of electronic components by measuring their electromagnetic spectrum during accelerated aging tests before deployment. This preliminary action creates a baseline database of normal and degraded component behavior, enabling the system to anticipate failures by comparing real-time measurements against these pre-established references. The preliminary characterization allows the system to detect subtle changes indicating impending failures.
3Reliability
If electromagnetic spectrum measurement is implemented for predictive control, then failure anticipation capability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by using a single electromagnetic spectrum measurement system to perform multiple functions: characterizing components during accelerated aging tests, establishing baseline signatures, monitoring component health during operation, and detecting degradation patterns. This multi-functional approach eliminates the need for separate testing and monitoring systems, reducing overall device complexity while maintaining comprehensive predictive capability.
Solution Approach 2:
The patent implements self-service by using the electronic components themselves as the measurement source. The components emit their own electromagnetic spectrum during normal operation, which is then measured and analyzed by the monitoring system. This eliminates the need for external excitation sources or complex test equipment, as the components provide their own diagnostic signals through their normal operational emissions.
4Measurement precision
If accelerated ageing tests are conducted to establish templates, then template accuracy is improved, but time and resource consumption increase
Solution Approach 1:
The patent applies parameter changes by conducting accelerated aging tests that modify environmental parameters (temperature, humidity, electrical stress) to induce rapid degradation. By changing these operating parameters to more extreme conditions, the system accelerates the aging process and obtains degradation data in compressed timeframes. The electromagnetic spectrum measurements taken under these accelerated conditions create accurate templates that can be used for predictive monitoring under normal operating conditions.
