Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed input channel measurement signal types are used, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The patent implements universality by designing measurement channels that can accept both electric field sensors and magnetic field sensors through a unified interface. The double pole double throw switches enable each measurement channel to be configured for different signal types, allowing a single channel to serve multiple measurement purposes (MT, AMT, CSAMT methods) without requiring separate dedicated channels for each sensor type.
Solution Approach 2:
The patent applies dynamics by using switchable connections that can dynamically reconfigure the measurement channels. The double pole double throw switches allow the system to adapt the connection configuration based on the specific measurement method being performed, enabling flexible switching between electric field and magnetic field sensor connections without physical reconfiguration of the entire system.
2Productivity
If fixed input channel measurement signal types are used, then ease of manufacture is improved, but productivity deteriorates
Solution Approach 1:
The universal channel design enables a single receiver system to perform multiple measurement types (MT, AMT, CSAMT) without requiring separate dedicated channels for each method. This multi-functionality increases productivity by allowing one instrument to replace multiple specialized instruments, thereby conducting more comprehensive field observations and analyses more efficiently.
Solution Approach 2:
The dynamic switching capability allows the system to adapt to different measurement requirements in real-time, enabling flexible configuration for various electromagnetic measurement methods. This dynamic reconfiguration capability improves field observation efficiency by allowing rapid switching between different measurement modes without requiring physical reconfiguration or multiple separate instruments.
3Ease of operation
If fixed input channel measurement signal types are used, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent simplifies operation by implementing dynamic switching controlled by a controller that automatically configures the measurement channels based on the selected measurement method. The double pole double throw switches are controlled by the FPGA controller to automatically connect the appropriate sensors to the measurement channels, eliminating the need for manual physical reconfiguration and making the system easier to operate across different measurement types.
