Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a case is used to protect the radiation detector, then the detector surface is protected, but the detector becomes bulky and image quality degrades
Solution Approach 1:
The protection unit is designed as a separate, detachable component that can be attached only when needed, rather than being permanently integrated into the detector housing. This allows the detector to remain compact during normal operation while providing protection when required.
Solution Approach 2:
The protective function is extracted from the main detector body as a separate front protection unit. This unit can be attached to the detector surface and removed when not needed, preventing the detector from being permanently bulky while still providing protection when required.
2Object-affected harmful factors
If a case is used to protect the radiation detector, then the detector surface is protected, but the distance between detector and subject increases
Solution Approach 1:
The front protection unit is designed as a thin protective layer that provides surface protection without adding significant thickness. This thin film approach ensures that the detector can maintain close proximity to the subject while still protecting the detector surface.
3Reliability
If the radiation detector is made larger to improve protection, then durability increases, but mobility around curved surfaces decreases
Solution Approach 1:
The detector system is segmented into a main detector body and a separate protective front unit. This segmentation allows the detector to maintain its compact, mobile form factor while providing enhanced protection through the attachable front unit.
Solution Approach 2:
The protective front unit is designed to be dynamically attachable and detachable, allowing the detector to adapt its configuration based on operational needs. When protection is needed, the front unit is attached; when mobility is prioritized, it can be removed.
4Measurement precision
If a fixed arm is provided on the detector to maintain constant distance, then image quality improves, but portability decreases
Solution Approach 1:
Instead of a fixed, heavy arm structure, the system uses a flexible cable connection that allows the detector to maintain connection to the imaging system while moving freely around the subject. The cable provides dynamic positioning capability without the weight and rigidity constraints of a fixed arm.
5Adaptability or versatility
If the radiation detector is made bendable to adapt to curved surfaces, then adaptability improves, but manufacturing difficulty increases
Solution Approach 1:
The bendable detector is constructed from modular components including flexible circuit boards, flexible display panels, and flexible battery packs. This modular segmentation allows each component to be manufactured separately using standard processes, then assembled into a flexible configuration that can conform to curved surfaces.
Solution Approach 2:
The detector employs composite material construction with flexible substrates, flexible electronics, and flexible power sources. These composite materials and structures enable the detector to bend and conform to curved surfaces while maintaining functionality and ease of manufacture through established flexible electronics techniques.
