Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed imaging parameter settings are used, then system simplicity is maintained, but operator flexibility and procedure-specific optimization are limited
Solution Approach 1:
The control panel dynamically adjusts the range and step size of configurable adjustments based on the selected imaging mode. Different modes (e.g., angiography, gastroenterology, cardiology) automatically set appropriate parameter ranges and step sizes, allowing the system to adapt to procedure-specific requirements without requiring complex manual configuration for each scenario.
Solution Approach 2:
The system changes multiple imaging parameters simultaneously based on the selected mode, including X-ray dose settings, image quality parameters, and control panel adjustment ranges. This coordinated parameter change allows operators to optimize imaging for specific procedures while maintaining system simplicity through automated mode-based configuration.
2Manufacturing precision
If fixed range and step size controls are provided, then device simplicity is maintained, but the ability to optimize imaging parameters for different procedures is limited
Solution Approach 1:
The control panel provides dynamic control where the range and step size of adjustments are not fixed but change based on the selected imaging mode. For example, in angiography mode, the system may provide finer step sizes for precise X-ray dose control, while in other modes, larger step sizes may be appropriate. This dynamic adjustment enables both high image quality and ease of operation.
Solution Approach 2:
The system performs preliminary configuration by automatically setting appropriate parameter ranges and step sizes based on the selected imaging mode before the operator begins adjusting individual parameters. This preliminary action reduces the complexity of operator control while maintaining the ability to achieve optimized image quality for each procedure type.
3Productivity
If preset imaging parameters are used, then system setup is simplified, but optimization for diverse medical procedures is compromised
Solution Approach 1:
The control panel is designed with multi-functionality, serving as a universal interface that adapts to different imaging modes and procedures. The same physical controls can adjust different parameters depending on the selected mode, and the system automatically configures appropriate ranges and step sizes for each procedure type, thereby improving both procedure efficiency and parameter optimization.
Solution Approach 2:
The system implements coordinated parameter changes across multiple imaging parameters when a mode is selected. This includes simultaneous adjustment of X-ray dose parameters, image quality settings, and control panel adjustment characteristics. Such coordinated changes enable procedure-specific optimization while maintaining simple operation through mode-based automation.

AI summary
Fluoroscopy imaging systems including an X-ray generator, a detector, and control circuitry coupled to the detector are provided. The control circuitry may be adapted to receive a digital signal from the detector, to process the digital signal, and to communicate the processed digital signal to a monitor for display during a fluoroscopy imaging operation. The fluoroscopy imaging systems may also include a user interface having at least one configurable adjustment configured to enable a user to adjust one or more imaging parameters affecting the digital signal during the fluoroscopy imaging operation. The control circuitry is adapted to set at least one of a range of the configurable adjustment, a step size of the configurable adjustment, or a default value of the configurable adjustment based on input from the user via the user interface.
