Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement protocols are parameterized with a specific coil configuration, then measurement precision is improved, but device complexity increases due to separate protocols for each coil configuration
Solution Approach 1:
The patent implements a universal measurement protocol that can be used across multiple coil configurations. The protocol includes placeholder parameters that are automatically adapted to the specific coil configuration during execution, eliminating the need for separate protocols for each coil type while maintaining measurement precision.
Solution Approach 2:
The patent uses parameter substitution where generic protocol parameters are dynamically replaced with coil-specific values based on the detected coil configuration. This allows a single protocol to adapt to different coil configurations through parameter changes rather than requiring separate protocols.
2Adaptability or versatility
If manual adjustment of measurement parameters is required, then adaptability to different coil configurations is achieved, but ease of operation deteriorates due to time-consuming adjustments
Solution Approach 1:
The system automatically detects the coil configuration and adjusts measurement parameters without requiring manual intervention from the operator. The protocol adjusting unit performs self-service by matching the detected coil configuration with appropriate parameters from the universal protocol, eliminating time-consuming manual adjustments.
Solution Approach 2:
The system implements feedback by detecting the actual coil configuration and using this information to automatically adjust protocol parameters. The detected coil configuration feeds back into the parameter selection process, ensuring optimal settings are applied without manual input.
3Measurement precision
If separate measurement protocols are compiled for each coil configuration, then measurement precision is maintained, but loss of time increases due to protocol selection and conversion efforts
Solution Approach 1:
Instead of maintaining separate protocol copies for each coil configuration, the system uses a single master protocol template that is dynamically instantiated with appropriate parameters based on the detected coil configuration. This eliminates the need to search through or convert multiple protocol copies.
Solution Approach 2:
The system performs preliminary detection of the coil configuration before protocol execution and pre-loads or pre-configures the appropriate parameters. This preliminary action eliminates the need for time-consuming protocol selection and conversion during the actual examination setup.
4Adaptability or versatility
If inexperienced users adjust protocol parameters manually, then adaptability to coil configurations can be achieved, but reliability decreases due to faulty adjustments
Solution Approach 1:
The system performs automatic parameter adjustment without requiring user expertise. The protocol adjusting unit independently detects the coil configuration and selects appropriate parameters, eliminating reliability issues associated with inexperienced users making faulty adjustments.
Solution Approach 2:
The system uses feedback from coil configuration detection to automatically determine appropriate parameters, removing the need for user judgment. This closed-loop approach ensures reliable parameter selection based on actual hardware configuration rather than user estimation.
