Engineering Contradiction Analysis
1Measurement precision
If existing noise detection devices are used to identify electronic components affected by noise, then the location of affected components can be determined, but the factors causing the noise cannot be identified, leading to prolonged inspection time
Solution Approach 1:
The patent segments the noise analysis process into distinct functional modules: a noise detection unit that detects noise signals, a data acquisition unit that collects operational data of electronic components, and an analysis unit that correlates noise signals with component operations. This segmentation enables comprehensive noise factor identification while maintaining efficient processing through specialized dedicated functions for each stage.
Solution Approach 2:
The patent implements preliminary action by pre-acquiring and storing operational data of electronic components before noise analysis is performed. The system maintains a database of component operation states, power consumption patterns, and operational timing information that can be immediately correlated with detected noise signals, eliminating the need for time-consuming data collection during actual inspection.
2Measurement precision
If comprehensive device information and identification conditions are acquired to identify noise factors, then noise source determination accuracy improves, but system complexity increases
Solution Approach 1:
The patent implements universality by designing an integrated control unit that performs multiple functions: acquiring device information, collecting operational data, detecting noise signals, and analyzing correlations between components and noise sources. This multi-functional approach consolidates what would otherwise require separate specialized devices, reducing overall system complexity while maintaining comprehensive noise analysis capability.
Solution Approach 2:
The patent introduces an intermediary analysis unit that acts as a mediator between raw noise detection data and final noise factor identification. This unit correlates noise signals with operational data, applies analysis conditions, and determines noise factors without requiring direct complex interactions between all system components, thereby simplifying the overall system architecture.
