Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If voltage sensing devices detect electromagnetic radiation in real-time, then detection speed is improved, but signal accuracy deteriorates due to interference from environmental factors
Solution Approach 1:
The patent segments the detected electromagnetic signal into multiple frequency components and time intervals. The processor analyzes specific frequency ranges (e.g., 50-60 Hz for AC voltage) separately from other signals, allowing real-time detection while filtering out interference through frequency-based segmentation.
Solution Approach 2:
The patent introduces an intermediary signal processing system that includes filters and reference signals. The processor uses reference electromagnetic signals representing known interference patterns and compares them with detected signals to identify and remove interference, thereby maintaining accuracy during real-time detection.
2Reliability
If voltage sensing devices continuously monitor electromagnetic radiation, then detection reliability is improved, but false alarms increase due to environmental interference
Solution Approach 1:
The patent implements feedback mechanisms where the processor continuously compares detected signals against reference signals and previously identified interference patterns. When a detected signal matches known interference characteristics, the system feedback-adjusts by filtering it out, preventing false alarms while maintaining reliable detection of actual voltage sources.
Solution Approach 2:
The patent converts harmful environmental interference signals into useful information by using them as reference patterns. The system detects interference signatures from environmental sources and leverages these same signatures to identify and filter out similar interference in future measurements, turning the harmful factor into a tool for improving detection accuracy.
3Loss of time
If voltage sensing devices process signal data in real-time, then response time is improved, but computational complexity increases due to interference filtering requirements
Solution Approach 1:
The patent applies preliminary action by pre-defining frequency ranges and interference patterns before real-time detection occurs. The processor has pre-established reference signals and filtering criteria, so during real-time operation it only needs to compare detected signals against these pre-prepared references, significantly reducing computational complexity while maintaining fast response.
