Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If imaging techniques are used to determine distinct features and movements within a workpiece or human body during treatment, then measurement precision is improved, but object-affected harmful factors increase due to additional radiation exposure
Solution Approach 1:
The particle beam system performs dual functions: it delivers therapeutic radiation treatment and simultaneously serves as an imaging tool by detecting scattered particles to create images of internal structures and movements. This eliminates the need for separate imaging devices that would add additional radiation exposure, as the same particle beam is used for both treatment and monitoring purposes.
Solution Approach 2:
The system uses its own therapeutic particle beam to generate imaging information by detecting scattered particles during treatment. The particle beam essentially images the workpiece or patient body using itself, eliminating the need for external imaging sources and their associated harmful radiation exposure.
2Measurement precision
If multiple particle beams of different types are emitted for monitoring and treatment, then measurement precision and treatment accuracy are improved, but device complexity increases
Solution Approach 1:
The particle beam system is designed to handle multiple types of hadronic particles (protons, neutrons, ions) within a single integrated platform. The system uses different particle types for different purposes: protons for therapeutic treatment and neutrons for imaging and monitoring, thereby achieving multiple functions without requiring entirely separate systems.
Solution Approach 2:
The system employs particle scatter detection as an intermediary mechanism to extract imaging information from the therapeutic beam itself. By detecting scattered particles that carry information about internal structures and movements, the system achieves monitoring capabilities without needing separate imaging hardware, thus managing complexity while improving precision.
