Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the radiation generating apparatus is set to fluoroscopic imaging mode with higher allowable radiation dose, then imaging quality and diagnostic capability are improved, but the risk of excessive radiation exposure increases
Solution Approach 1:
The system dynamically adjusts the allowable radiation dose based on the selected imaging mode. When fluoroscopic mode is selected, a higher allowable dose is permitted; when dynamic imaging mode is selected, a lower allowable dose is enforced. This dynamic parameter adjustment resolves the contradiction by allowing high-quality fluoroscopic imaging when needed while preventing excessive radiation exposure during dynamic imaging.
Solution Approach 2:
The patent changes the radiation dose parameter according to the imaging mode. The control unit sets different maximum radiation dose values depending on whether fluoroscopic mode or dynamic imaging mode is selected. This parameter change strategy enables the system to optimize imaging quality for each mode while maintaining safe radiation exposure levels appropriate to the specific imaging task.
2Adaptability or versatility
If the system allows flexible radiation dose setting for different imaging modes, then adaptability is improved, but the risk of incorrect radiation exposure setting increases
Solution Approach 1:
The control unit provides feedback control by automatically adjusting the radiation dose settings based on the selected imaging mode. When the operator selects fluoroscopic or dynamic imaging mode, the control unit automatically sets the appropriate maximum radiation dose, preventing manual errors. This feedback mechanism maintains reliability while preserving adaptability across different imaging modes.
Solution Approach 2:
The system performs self-service by automatically configuring the radiation dose parameters according to the imaging mode selection. The control unit independently manages the radiation dose settings without requiring manual intervention, ensuring that the correct dose is always applied for the selected mode. This self-service approach eliminates human error while maintaining mode flexibility.
3Ease of operation
If mobile dynamic imaging apparatus is deployed in general hospital rooms, then accessibility and patient convenience are improved, but the financial burden on hospitals increases
Solution Approach 1:
The mobile radiographic imaging system is designed to perform multiple functions: it can operate in both fluoroscopic imaging mode and dynamic imaging mode. This multi-functionality allows a single device to replace what would traditionally require two separate apparatuses, reducing the financial burden on hospitals while maintaining accessibility and versatility in general hospital rooms.
