Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high radiation amount is used to improve image quality, then image quality increases, but radiation exposure to patient and operator increases causing health risks
Solution Approach 1:
The patent implements dynamic control of radiation parameters allowing real-time adjustment during medical procedures. The system transitions from static fixed radiation levels to dynamic variable radiation levels, enabling operators to adjust radiation dose and frame rate according to procedural needs, thereby optimizing image quality while minimizing radiation exposure.
Solution Approach 2:
The system enables continuous adjustment of radiation parameters including radiation dose, frame rate, and exposure time. By changing these parameters dynamically during procedures, the system can maintain optimal image quality at the lowest necessary radiation levels, resolving the contradiction between image quality and radiation safety.
2Manufacturing precision
If high frame rate is maintained to ensure maximum image quality, then image quality improves, but radiation exposure increases
Solution Approach 1:
The system dynamically adjusts frame rate during procedures rather than maintaining a fixed high frame rate. Operators can lower frame rate when high-quality imaging is not critical, thereby reducing radiation dose while maintaining adequate image quality for procedural needs.
Solution Approach 2:
The system applies radiation at partial levels rather than continuously at maximum levels. By using variable frame rates and adjusting radiation delivery to match actual procedural requirements, the system avoids excessive radiation exposure while maintaining sufficient image quality.
3Object-affected harmful factors
If manual adjustment of frame rate is required to optimize radiation levels, then radiation control improves, but operational complexity and interruption increase
Solution Approach 1:
The system provides automatic radiation level recommendations and adjustments based on real-time procedural data and pre-set protocols. Rather than requiring constant manual intervention, the system serves itself by automatically optimizing radiation parameters while allowing operator override, thereby improving radiation control without significantly increasing operational complexity.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor procedural progress and automatically adjust radiation parameters accordingly. Real-time feedback from sensors and procedural data enables the system to self-regulate radiation levels, reducing the need for manual adjustment while maintaining optimal radiation control.
4Device complexity
If fixed radiation level is used throughout the procedure, then device simplicity is maintained, but radiation optimization and image quality vary
Solution Approach 1:
The system transitions from fixed static radiation control to dynamic adjustable radiation control. By implementing variable radiation levels that can be adjusted during procedures, the system maintains adequate image quality consistency across different procedural stages without requiring complex control mechanisms, as adjustments are made through simplified interfaces.
