Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the detecting device is made light, thin, and with a narrow frame, then the device meets modern design requirements for portability and aesthetics, but the scintillator layer becomes vulnerable to collision damage causing defects
Solution Approach 1:
The patent applies beforehand cushioning by adding a protective layer between the scintillator layer and the external environment. This protective layer absorbs and distributes collision forces before they reach the scintillator layer, preventing defects while maintaining the device's lightweight and thin design. The protective layer acts as a buffer that cushions against impacts without adding significant weight or thickness.
2Length of stationary object
If the scintillator layer is made thinner to reduce device thickness, then the device meets narrow frame requirements, but the detection effectiveness and display quality deteriorate
Solution Approach 1:
The patent employs composite materials by combining the scintillator layer with a protective layer having different mechanical properties. The scintillator layer maintains its thin profile for device compactness, while the protective layer provides enhanced mechanical strength and collision resistance. This composite structure allows the thin scintillator layer to function effectively without suffering from collision damage that would degrade detection quality.
