Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If single equipment is used for magnetotelluric detection, then device complexity is reduced, but detection efficiency and productivity are significantly lowered
Solution Approach 1:
The detection system is divided into one host unit and multiple extension units (N2-1 extensions), where each extension unit can independently detect at a measuring point. This segmentation allows parallel detection across multiple points simultaneously, increasing productivity by N2 times compared to single-point detection while distributing the system complexity across modular components.
2Productivity
If multiple detection equipment are used for synchronous detection, then detection efficiency is improved, but device complexity and operational complexity increase
Solution Approach 1:
Multiple extension units are wirelessly connected to and controlled by a single host unit through RF communication. The host unit performs unified configuration, control, and data collection for all extensions, merging the operational complexity into a single control interface while maintaining parallel detection capabilities across multiple points.
Solution Approach 2:
The system implements real-time feedback mechanisms where extension units transmit detection data and status information to the host unit, which then provides configuration updates and control commands. This feedback loop enables automated coordination of multiple units, reducing manual operational complexity while maintaining synchronous detection across all points.
3Measurement precision
If in-situ data acquisition and indoor data inversion are used separately, then measurement precision is maintained, but loss of time in data processing increases
Solution Approach 1:
The host unit performs real-time inversion calculations immediately after data acquisition from extension units, rather than delaying processing until indoor analysis. This preliminary action eliminates the time loss associated with separate indoor inversion processes while maintaining measurement precision through immediate computational processing of fresh detection data.
4Area of stationary object
If large detection areas are covered, then area coverage is improved, but detection time and inversion time increase
Solution Approach 1:
The large detection area is divided into multiple measurement points, with each extension unit assigned to detect at a specific point. This segmentation enables simultaneous detection across all points in parallel, covering the entire large area in a single detection campaign rather than sequentially visiting each point, thereby dramatically reducing total detection time while maintaining comprehensive area coverage.
