Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional medical imaging devices are used without real-time monitoring, then the device structure remains simple, but the positioning accuracy of ionization chambers deteriorates leading to low exposure doses and poor image quality
Solution Approach 1:
The patent implements real-time monitoring of ionization chamber positions and gantry component movements through feedback mechanisms. Position information is continuously obtained and used to adjust scanning parameters and projection data, ensuring accurate detection region coverage while adapting to dynamic changes in device configuration
Solution Approach 2:
The patent replaces traditional mechanical positioning methods with information-based control systems. Instead of relying solely on physical markers or manual alignment, the system uses obtained position information and movement data to computationally determine detection regions and adjust imaging parameters, achieving higher precision without proportional increases in mechanical complexity
2Manufacturing precision
If ionization chamber positions are not accurately determined, then the scanning process is simpler, but image quality deteriorates due to obscured positioning and low exposure doses
Solution Approach 1:
The system performs self-adjustment by automatically obtaining position information of ionization chambers and gantry components, determining detection regions, and adjusting scanning parameters without requiring manual intervention. The device monitors its own state and makes real-time corrections to ensure accurate detection region coverage
Solution Approach 2:
The patent determines detection regions and adjusts projection data before the actual scanning process begins. By pre-calculating the appropriate scanning parameters and projection data based on obtained position information, the system ensures accurate detection region coverage is established in advance, avoiding the need for complex real-time adjustments during scanning
3Productivity
If real-time monitoring of gantry components is implemented, then diagnostic efficiency improves through adaptive parameter adjustment, but the system complexity increases
Solution Approach 1:
The patent implements dynamic adjustment of scanning parameters based on real-time movement information of gantry components. The system adapts scanning parameters and projection data according to the actual position and movement state of device components, enabling flexible and efficient diagnostic procedures that respond to changing system conditions
Solution Approach 2:
The control system performs multiple functions through a unified approach: obtaining position information, determining detection regions, adjusting scanning parameters, and modifying projection data. This multi-functional design consolidates what would otherwise require separate systems into a single integrated control mechanism, improving diagnostic efficiency without proportionally increasing overall system complexity
