Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio wave energy is transmitted to treat a lesion inside the living body, then the treatment effect is improved, but radio wave energy is also transmitted to undesired areas causing harmful effects to normal areas
Solution Approach 1:
The system performs preliminary prediction of radio wave focusing points using an electromagnetic numerical model before actual treatment. This preliminary action identifies potential harmful focusing points in advance, allowing the system to adjust focusing parameters to prevent energy concentration in normal areas before treatment begins
Solution Approach 2:
The system uses feedback from the electromagnetic numerical model prediction to continuously optimize focusing parameters. The predicted focusing points are fed back into the parameter optimization process, allowing real-time adjustment of radio wave transmission to ensure energy is concentrated only at the target lesion and not at surrounding normal areas
2Object-affected harmful factors
If existing methods are used to prevent harmful effects, then safety is improved, but additional equipment and monitoring requirements increase system complexity
Solution Approach 1:
The system performs self-monitoring and self-adjustment through automated electromagnetic numerical model prediction and focusing parameter optimization. The processor automatically identifies harmful focusing points and adjusts transmission parameters without requiring external temperature monitoring devices or manual intervention by medical professionals
Solution Approach 2:
The system replaces physical monitoring equipment (temperature monitoring devices, cooling devices) with computational prediction using electromagnetic numerical models. The focus shifts from mechanical/physical monitoring to software-based prediction and optimization, reducing hardware complexity while maintaining or improving safety
3Manufacturing precision
If radio wave energy is focused at a target point, then treatment precision is improved, but unnecessary focusing points are created at other locations
Solution Approach 1:
The electromagnetic numerical model predicts all potential focusing points (both desired and undesired) before treatment. This preliminary identification of unnecessary focusing points allows the system to pre-adjust focusing parameters to eliminate harmful concentration points while maintaining precision at the target lesion
Solution Approach 2:
The system optimizes focusing parameters (amplitude, phase, frequency) based on predicted focusing points. By changing these parameters, the system redistributes energy concentration to maintain precise targeting at the lesion while eliminating unnecessary focusing points in surrounding areas through constructive and destructive interference patterns
