Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional X-ray imaging systems using film or computed radiography are used, then image processing and transport are performed, but time delay occurs in obtaining images for viewing and diagnosis
Solution Approach 1:
The patent replaces the mechanical film processing system with a digital detector that directly captures and converts X-ray images into digital signals. The digital detector eliminates the need for physical film transport and chemical processing, enabling immediate image availability for diagnosis and significantly reducing the time delay in image acquisition.
Solution Approach 2:
The patent creates a digital copy of the X-ray image through the digital detector, which can be instantly stored, transmitted, and displayed without requiring physical film handling. This digital copying process eliminates the time-consuming steps of film development and physical transport, allowing rapid image retrieval and sharing.
2Productivity
If conventional radiographic imaging systems are replaced with digital radiographic imaging systems, then image acquisition speed improves, but cost increases
Solution Approach 1:
The patent segments the X-ray imaging system into independent components: the existing X-ray source remains unchanged while a separate digital detector is introduced. This modular approach allows the digital detector to be added independently without replacing the entire imaging system, thereby reducing the overall cost of upgrading from conventional to digital radiography.
Solution Approach 2:
The digital detector is designed to work with existing X-ray sources and can interface with various imaging workflows, making it a universal component that enhances both conventional and digital systems. This multi-functionality allows hospitals to upgrade incrementally rather than replacing entire systems, reducing implementation costs.
3Reliability
If digital X-ray detectors are integrated with source controllers, then system coordination improves, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary interface that enables communication between the digital detector and the existing source controller without requiring deep integration. This intermediary layer translates signals and coordinates operations between the two components, maintaining reliable system coordination while avoiding the complexity of direct integration.
Solution Approach 2:
The digital detector is designed with self-contained control electronics that can operate independently and autonomously manage its own functions. This self-service capability reduces the need for complex external control systems and minimizes integration complexity while maintaining reliable operation.
