Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated cabling member is provided for outputting the voltage signal from the coil, then the signal can be transmitted reliably, but the cabling structure becomes complex and cost increases
Solution Approach 1:
The patent combines the signal output function with the existing drive cabling member. The drive line that supplies drive signals to the coil is merged with the signal output line that transmits voltage signals from the coil, eliminating the need for a separate dedicated cabling member for signal output.
Solution Approach 2:
The cabling member is designed to serve multiple functions simultaneously. It acts as both the drive line for supplying electrical signals to the coil and the signal output line for transmitting voltage signals from the coil, making the cabling member a multi-functional component.
2Measurement precision
If a dedicated cabling member is provided for the flow detecting sensor, then the detection signal can be output effectively, but the cabling structure becomes more complex and cost increases
Solution Approach 1:
The patent merges the signal output line for the flow detecting sensor with the existing cabling member used for the energy conversion element. This integration allows the same cabling member to carry both drive signals and detection signals, reducing overall cabling complexity.
Solution Approach 2:
The cabling member is designed with multi-functionality to handle both the drive line function for the energy conversion element and the signal output function for the flow detecting sensor, thereby reducing the total number of cabling components needed.
3Reliability
If separate cabling members are provided for energy conversion element and flow detecting sensor, then each component can be connected reliably, but the overall cabling structure becomes complex
Solution Approach 1:
The patent merges the cabling functions into a single integrated cabling member that serves both the energy conversion element and the flow detecting sensor. This unified approach maintains connection reliability while significantly reducing structural complexity.
Solution Approach 2:
The cabling member is designed as a universal component that performs multiple functions: it acts as the drive line for the energy conversion element and simultaneously as the signal output line for the flow detecting sensor, thereby simplifying the overall cabling structure.
