Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fiber-based particle beam detectors are used, then radiation detection capability is provided, but radiation damage occurs after a few years of use and manufacturing costs are high
Solution Approach 1:
The patent changes the material parameter from fiber-optic material to liquid scintillation material, which has different radiation resistance properties. This material substitution resolves the contradiction by providing a detector that maintains reliability without suffering from the same radiation damage limitations as fiber-based detectors
Solution Approach 2:
The liquid scintillation material can be readily replaced when damaged, treating the scintillation medium as a replaceable component rather than a permanent structure. This approach reduces long-term costs and improves reliability by allowing easy replacement of radiation-damaged material
2Ease of manufacture
If liquid scintillation material is used in channels, then replacement is easy, but capillarity issues during filling and vacuum incompatibility limit resolution and application
Solution Approach 1:
The patent applies different surface treatments to different regions of the channel structure. The outer surface maintains properties for easy filling, while the inner surface is treated to prevent capillarity issues. This local differentiation resolves the contradiction between ease of manufacture and manufacturing precision
Solution Approach 2:
The patent changes the surface chemistry parameter of the channel walls through silanization treatment. This modifies the interaction between liquid scintillation material and channel surfaces, eliminating capillarity-induced filling problems while maintaining replaceability
3Manufacturing precision
If small microchannels are manufactured for high resolution, then detector resolution increases, but capillarity effects and filling difficulties make manufacturing very difficult and costly
Solution Approach 1:
The patent applies silanization treatment to the channel surfaces before filling with liquid scintillation material. This preliminary surface modification prevents capillarity issues during the subsequent filling process, making small microchannel fabrication feasible and reducing manufacturing difficulty
Solution Approach 2:
The silane coating acts as an intermediary layer between the microchannel walls and the liquid scintillation material. This intermediate layer modifies surface properties to eliminate harmful capillarity effects while allowing complete filling of small channels, resolving the manufacturing difficulty
4Ease of manufacture
If liquid scintillation detectors are used, then material can be replaced, but they cannot be used inside vacuumized environments
Solution Approach 1:
The patent applies different surface treatments to different regions of the channel structure. The outer surface maintains properties for easy filling, while the inner surface is treated to prevent capillarity issues. This local differentiation resolves the contradiction between ease of manufacture and manufacturing precision
Solution Approach 2:
The patent changes the surface chemistry parameter of the channel walls through silanization treatment. This modifies the interaction between liquid scintillation material and channel surfaces, eliminating capillarity-induced filling problems while maintaining replaceability
