Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional film-based X-ray imaging is used, then images can be captured, but additional processing steps (developing, storing films) are required and image viewing is delayed
Solution Approach 1:
The patent replaces the mechanical film-based imaging system with a digital imaging plate system. The imaging plate uses photostimulated luminescence to convert X-ray exposure directly into readable signals, eliminating the need for chemical developing processes and film handling, thereby reducing both time loss and processing complexity
Solution Approach 2:
The patent creates a digital copy of the X-ray image through photostimulated luminescence reading, where the imaging plate stores the latent image and allows multiple readings without degradation. This digital copying eliminates the need for physical film processing and enables immediate image retrieval and viewing
2Loss of substance
If films and developing solutions are used, then X-ray images can be captured, but consumables are required and storage space is increased
Solution Approach 1:
The imaging plate can be reused after scanning by erasing the latent image and exposing it again to X-rays. This recovery process eliminates the need for continuous consumption of films and developing solutions, reducing substance loss while maintaining imaging capability
Solution Approach 2:
The imaging plate system is self-sufficient, requiring no external developing solutions or chemical reagents. The plate automatically stores the latent image and can be read multiple times, eliminating dependency on consumables and reducing the need for extensive storage facilities for films and chemicals
3Productivity
If a laser beam scanning system is used, then digital signals can be acquired, but the laser must remain on the IP for sufficient time
Solution Approach 1:
The patent employs periodic scanning of the laser beam across the imaging plate in a systematic pattern. This periodic action allows the laser to dwell on each region for the necessary duration to read the latent image while maintaining overall high productivity through efficient scanning cycles and rapid plate transfer mechanisms
