Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single acquisition parameter set is used for X-ray imaging, then the imaging process is simple and fast, but the visibility of multiple objects with different material properties cannot be simultaneously optimized
Solution Approach 1:
The system dynamically switches between multiple acquisition parameter sets during the imaging process. The control device changes acquisition parameters (such as tube voltage, tube current, pulse width) based on the temporal position within the sequence, enabling adaptive optimization of object visibility without requiring manual reconfiguration for each object type
Solution Approach 2:
The patent applies parameter changes by varying acquisition parameters across different time points in the image sequence. Different parameter sets are assigned to different temporal positions, allowing the system to optimize visibility for different objects at different times. The fused output image combines information from images acquired with different parameters to achieve comprehensive visibility optimization
2Measurement precision
If manual selection of acquisition parameters is performed by the user, then the system configuration is simple, but the visibility of relevant objects is suboptimal
Solution Approach 1:
The system performs self-service by automatically selecting and switching between acquisition parameter sets without requiring manual user intervention. The control device autonomously determines which parameter set to use based on the temporal position in the sequence, eliminating the need for users to manually configure parameters while achieving optimized visibility for multiple objects
Solution Approach 2:
The system incorporates feedback mechanisms where the control device monitors the imaging process and automatically adjusts parameter selection based on the detected objects and their material properties. This feedback loop enables the system to adaptively optimize visibility without manual input from the operator
3Measurement precision
If acquisition parameters are optimized for a specific object class, then that object type is clearly visible, but other objects with different material properties become difficult or invisible
Solution Approach 1:
The system employs periodic action by cycling through multiple acquisition parameter sets in a predetermined sequence. Each parameter set is applied for a specific temporal duration, creating a periodic pattern of parameter changes that ensures different objects are optimally visualized at different phases of the cycle. The fused output image integrates information from all phases to achieve comprehensive object visibility
Solution Approach 2:
The imaging sequence is segmented into different temporal segments, each associated with a specific acquisition parameter set optimized for particular object types. By dividing the overall imaging process into segments with specialized parameters, the system can optimize visibility for different objects in different segments while maintaining overall multi-object visibility through fusion
