Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple data transmission and processing methods are used, then device complexity is reduced, but data integrity and reliability deteriorate due to disruption and lack of comprehensive data
Solution Approach 1:
The patent segments data transmission into multiple channels: power line carrier transmission for continuous data and wireless transmission for backup. This segmentation ensures that if one channel is disrupted, the other can maintain data integrity, resolving the contradiction between simple transmission methods and reliable data delivery.
Solution Approach 2:
The patent changes the transmission parameter by using power line carrier technology to transmit data through the power supply line. This alternative transmission path bypasses traditional communication channels that are prone to disruption, thereby improving data reliability without significantly increasing device complexity.
2Measurement precision
If only geophysical data is collected, then measurement precision is sufficient for basic exploration, but the intuitive representation of underground situation deteriorates
Solution Approach 1:
The patent merges multiple data sources including power consumption data, geophysical data, and operational parameters into a comprehensive dataset. This combination provides both precise measurements and intuitive representation of underground conditions, resolving the contradiction between measurement precision and information completeness.
Solution Approach 2:
The power line carrier system serves multiple functions: it provides power supply, transmits data, and monitors power consumption patterns that reflect drilling conditions. This multi-functionality enables comprehensive data collection without adding separate dedicated systems, maintaining measurement precision while enhancing intuitive understanding of underground situations.
3Productivity
If continuous monitoring is implemented, then productivity is improved through real-time data, but use of energy increases due to continuous data transmission and processing
Solution Approach 1:
The power line carrier system simultaneously provides power supply and data transmission functions through the same infrastructure. This eliminates the need for separate power and communication systems, reducing overall energy consumption while maintaining continuous monitoring capability and improving productivity.
Solution Approach 2:
The system uses the existing power supply infrastructure to carry data signals, making the power line serve itself for dual purposes. This self-service approach avoids additional energy-consuming transmission systems while enabling continuous monitoring, thus improving productivity without proportionally increasing energy use.

Data Source
AI summary
A method for processing fused “underground+ground” data in deep formation exploration includes: collecting underground multi-source data by an underground intelligent probing rod, preprocessing the multi-source data to obtain an original digital signal, storing the original digital signal in an underground memory, obtaining continuous depth data by a ground device; performing high-bitrate and low-bitrate compression on the original digital signal, and modulating compressed signals; driving modulated signals by power, so the modulated signal is transmitted in a drilling stem with cable in a form of a power line carrier and then output, or first transmitted in a first section of the drilling stem with cable, re-collected in a short drill pipe with repeater, re-emitted to a second section of the drilling stem with cable, and then output; when a transmission line is disconnected, synchronizing and fusing data; and finally using fused data and the data output by the transmission line as final output data.
