Innovation Solution
The X-ray detector design includes a cassette with multiple terminals and a bucky with electrodes configured to connect in multiple modes, allowing for battery charging and secure mounting at various angles without the need for additional cables or devices, using a combination of ground and plus electrodes with pogo-pin type connections and insulation layers for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cassette is disconnected from the bucky, then the cassette can be used independently with its rechargeable battery, but the battery charging efficiency and operational flexibility are reduced
Solution Approach 1:
The connection interface between cassette and bucky is designed to serve multiple functions: it provides electrical connection for battery charging, mechanical mounting support at various angles, and signal transmission. The first terminal connects to the first electrode (ground) and the second terminal connects to at least one of the plurality of second electrodes (plus electrodes), enabling the same interface to handle both power/charging and mechanical positioning functions simultaneously.
Solution Approach 2:
The cassette is designed to be mountable on the bucky at various angles while maintaining proper electrical connection. The connection interface accommodates angular variations through the arrangement of terminals and electrodes, allowing the cassette to be positioned at different orientations (e.g., 0 degrees, 45 degrees, 90 degrees) relative to the bucky while still establishing contact between the first terminal with first electrode and second terminal with second electrodes for effective battery charging.
2Adaptability or versatility
If multiple second electrodes are used in the bucky, then the battery can be charged in multiple connection modes, but the device complexity increases
Solution Approach 1:
The electrical connection is segmented into multiple independent terminals and electrodes: the first terminal connects to the first electrode (ground) and the second terminal connects to at least one of the plurality of second electrodes (plus electrodes). This segmentation allows different combinations of second electrodes to be engaged with the second terminal, creating multiple connection modes for battery charging while keeping each individual connection simple and manageable.
Solution Approach 2:
The plurality of second electrodes are all connected to the same power supply but can be selectively engaged with the second terminal of the cassette. This universal power supply connection allows any engaged second electrode to provide charging current, enabling multiple connection modes (different angular positions) while using a single power supply source, thereby avoiding the need for separate power circuits for each mode.
3Adaptability or versatility
If the cassette is mounted at various angles on the bucky, then the operational flexibility is enhanced, but the measurement precision and connection reliability may deteriorate
Solution Approach 1:
The connection interface is designed to dynamically adapt to different mounting angles. The cassette can be mounted at various angles (0°, 45°, 90°, etc.) on the bucky, and the electrical connection is maintained through the flexible engagement between the second terminal and multiple second electrodes. The design accommodates angular variations while ensuring reliable contact between the first terminal with first electrode and the engaged second terminal with second electrodes, maintaining connection reliability across different orientations.
Solution Approach 2:
The arrangement of terminals on the cassette and electrodes on the bucky is designed with asymmetric positioning to accommodate various mounting angles. The first terminal is positioned to connect with the first electrode (ground) while the second terminal is positioned to engage with specific second electrodes (plus electrodes) at different angular orientations. This asymmetric design ensures that proper electrical connection is maintained regardless of the angle at which the cassette is mounted on the bucky.
