Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data processing algorithms are used to determine passing time based on limited data packets and signal strength data, then passing time can be determined, but accuracy is negatively influenced and processing time increases
Solution Approach 1:
The patent extracts and utilizes phase information from the received signal, separating it from conventional signal strength-based processing. By focusing specifically on phase transitions rather than processing the entire data set, the system achieves accurate passing time determination without the computational burden of comprehensive data processing algorithms
Solution Approach 2:
The system continuously monitors phase information in real-time and identifies phase transitions as they occur. This preliminary detection of phase changes enables immediate passing time determination without waiting for complete data collection, eliminating processing delays while maintaining accuracy
2Measurement precision
If conventional timing systems use limited data packets and signal strength data, then processing can be performed, but accuracy of passing time determination is reduced
Solution Approach 1:
The patent changes the measurement parameter from signal strength to phase information. Phase transitions provide distinct, easily identifiable markers for passing events, enabling accurate determination even with limited data packets. This parameter change transforms insufficient signal strength data into reliable phase transition detection
3Measurement precision
If data processing algorithms process complete data sets before determining passing time, then accuracy can be maintained, but real-time processing capability is lost
Solution Approach 1:
The system extracts phase information as a specific feature from the received signal, separating it from complete data set processing. This extraction enables focused analysis of only the critical phase transition moments, achieving both accuracy and real-time processing capability by eliminating unnecessary computational steps
Solution Approach 2:
Phase information is continuously monitored and phase transitions are detected in real-time as they occur. This preliminary detection eliminates the need to wait for complete data collection, enabling immediate passing time determination while maintaining accuracy through continuous phase monitoring
