Engineering Contradiction Analysis
1Ease of manufacture
If wireless data transmission is used for seismic monitoring, then installation cost and environmental impact are reduced, but data transmission rate becomes insufficient for large volume seismic data
Solution Approach 1:
The patent extracts and transmits only the essential seismic signal characteristics (complex amplitude, phase, frequency) rather than the complete raw seismic data. By separating the critical information from the full data set, the system achieves adequate transmission quality at much lower data rates suitable for wireless links.
Solution Approach 2:
The patent transforms the seismic data from time-domain raw signals to frequency-domain parameters (amplitude, phase, frequency). This parameter transformation reduces the data dimensionality and enables efficient compression, allowing wireless transmission at reduced bandwidth while preserving essential seismic information.
2Measurement precision
If complete seismic data is transmitted wirelessly, then data quality is maintained, but power consumption increases due to large data volume
Solution Approach 1:
The system extracts only the essential seismic signal parameters (complex amplitude, phase, frequency) from the complete data set. This extraction maintains the critical information needed for seismic interpretation while dramatically reducing the data volume that requires power-intensive wireless transmission.
Solution Approach 2:
The patent transmits a partial representation of the seismic data that contains sufficient information for monitoring purposes. By transmitting only the essential parameters rather than complete data, the system achieves adequate measurement quality with significantly reduced energy consumption.
3Speed
If physical cable links are installed for data transmission, then data transmission rate is sufficient, but installation cost and environmental disruption increase
Solution Approach 1:
The patent replaces the mechanical cable installation system with a wireless transmission system. By eliminating the need for physical cable laying through boreholes and surface trenches, the system avoids installation disruption while achieving sufficient effective transmission rates through data compression.
4Ease of operation
If battery-powered recording equipment is used, then installation flexibility is improved, but operational duration is limited by battery capacity
Solution Approach 1:
The system uses periodic seismic signals with known characteristics (frequency, amplitude, phase) that are transmitted at regular intervals. This periodic operation allows the recording equipment to remain in low-power standby mode between transmissions, extending battery life while maintaining monitoring capability.
Solution Approach 2:
By transforming continuous seismic data into discrete periodic parameter measurements (amplitude, phase, frequency at specific time intervals), the system reduces the continuous data acquisition burden and enables longer operational duration on battery power.
