Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image capturing control apparatus acquires radiation images from all radiation image capturing apparatuses and selects a significant image, then the system can capture images from multiple apparatuses, but the accuracy in selecting the significant radiation image deteriorates because the control apparatus may select an image from an inappropriate apparatus
Solution Approach 1:
A calculation unit is introduced as an intermediary component between the image capturing control apparatus and the radiation image capturing apparatuses. This calculation unit computes similarity metrics between captured images and reference images, providing objective criteria for selection. The intermediary processing layer prevents direct erroneous selection by the control apparatus while maintaining the multi-apparatus capture capability.
Solution Approach 2:
The system implements a feedback mechanism where the calculation unit continuously computes similarity information and feeds it back to the image capturing control apparatus. This feedback loop enables the control apparatus to make informed selection decisions based on quantitative similarity metrics rather than arbitrary selection, thereby improving selection accuracy while maintaining versatility.
2Productivity
If the image capturing control apparatus communicates with multiple radiation image capturing apparatuses to acquire images, then the system enables comprehensive image capture, but the device complexity increases due to multiple communication interfaces and selection logic
Solution Approach 1:
The selection function is extracted from the image capturing control apparatus and transferred to a dedicated calculation unit. This extraction separates the communication and image acquisition functions (handled by the control apparatus) from the image evaluation and selection function (handled by the calculation unit). The separation reduces the complexity burden on the control apparatus while maintaining comprehensive multi-apparatus capture capability.
