Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional fluorescent materials or semiconductors are used for charged particle detection, then high-energy charged particles (100 eV or higher) can be detected, but low-energy charged particles cannot be detected and only vacuum conditions are suitable
Solution Approach 1:
The patent changes the detection parameter from conventional fluorescent/scintillation materials to electrostatic charge accumulation materials that respond to low-energy charged particles. The key parameter change is the detection threshold energy, enabling detection of particles with energies much lower than the conventional 100 eV requirement, while also enabling operation in atmospheric conditions rather than requiring vacuum.
2Measurement precision
If measuring equipment other than the detection material is required, then detection accuracy may be improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The detection material itself performs the detection function by accumulating electrostatic charge from incident charged particles and emitting light accordingly. The material serves its own detection purpose without requiring external measuring equipment, making the system simpler and easier to operate while maintaining detection capability.
3Reliability
If vacuum conditions are required for detection, then detection reliability is improved, but ease of operation and adaptability to real-world environments deteriorate
Solution Approach 1:
The patent changes the operational environment parameter from vacuum to atmospheric conditions. The electrostatic charge accumulation mechanism works effectively in air and other atmospheric conditions, eliminating the need for vacuum systems and enabling practical applications in real-world environments while maintaining detection reliability.
