Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a case is used to protect the detector, then the detector surface is protected, but the detector becomes bulky and difficult to use
Solution Approach 1:
The patent applies a flexible protective layer that can be attached to and detached from the detector surface. This flexible shell protects the detector from scratches and damage while maintaining flexibility and portability, eliminating the need for a bulky rigid case. The protective layer conforms to the detector's shape and can be easily stored when not in use.
Solution Approach 2:
The protective function is separated from the main detector body by using a detachable protective layer. This segmentation allows the detector to be protected without being permanently encased in a bulky structure. The protective layer can be applied only when needed and removed for storage or charging, maintaining ease of operation.
2Reliability
If a case is used to protect the detector, then the detector surface is protected, but the distance between the subject and the detector increases, degrading image quality
Solution Approach 1:
The flexible protective layer is designed to be thin and conformal, maintaining close contact with the detector surface without creating significant distance from the subject. This allows the detector to remain positioned optimally for capturing radiographic images while still receiving protection from the flexible shell.
3Reliability
If the detector is made larger to improve protection, then the detector surface is better protected, but it becomes difficult to rotate around the subject
Solution Approach 1:
The flexible protective layer allows the detector to maintain a compact size while still receiving adequate protection. This flexibility enables the detector to be easily rotated and positioned around round subjects without the constraints imposed by a bulky rigid case, improving adaptability for various imaging scenarios.
4Measurement precision
If a fixed arm is provided on the detector to maintain constant distance, then the distance control is improved, but the detector becomes heavy and less portable
Solution Approach 1:
The patent employs a movable support structure with wheels that allows the detector to dynamically adjust its position and maintain constant distance from round subjects during rotation. This dynamic system replaces heavy fixed arms with a lighter, more portable wheel-based mechanism that can adapt to different imaging positions without compromising distance control precision.
