Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional neutron emission detection technologies are used, then detection capability is provided, but the device is not portable and cannot effectively detect neutron emissions from multiple sources
Solution Approach 1:
The device is divided into multiple independent components: a housing containing a moderator structure, a separate neutron detection element with reactive material, and plate electrodes. This segmentation allows each component to be optimized independently while maintaining overall portability and multi-source detection capability.
Solution Approach 2:
The neutron detection element with reactive material serves multiple functions: detecting neutrons from various sources, providing directional detection capability, and enabling portable operation. The plate electrodes configuration allows the device to detect neutron emissions from more than one source simultaneously while maintaining a compact form factor.
2Object-affected harmful factors
If radiation shielding is added to the device, then protection from radiation is improved, but the device size and weight increase
Solution Approach 1:
The housing provides radiation shielding specifically for the neutron detection element and internal components, concentrating protective mass where it is most needed rather than uniformly throughout the entire device. This localized shielding approach reduces overall weight while maintaining adequate protection.
Solution Approach 2:
The device utilizes composite construction combining the housing material with the moderator structure material (energy absorbing material) and the neutron reactive material coating. This composite approach allows optimized protection with minimal weight by selecting materials with high shielding efficiency.
3Measurement precision
If the neutron detection element uses reactive material on a planar substrate, then detection sensitivity is improved, but the device becomes more complex to manufacture
Solution Approach 1:
The planar substrate acts as an intermediary carrier that facilitates the deposition of neutron reactive material. This intermediate layer simplifies the manufacturing process by providing a stable base for coating techniques while maintaining the high detection sensitivity required for accurate neutron measurement.
Solution Approach 2:
The manufacturing process utilizes controlled parameter changes during material deposition, such as adjusting deposition thickness, material composition ratios, and substrate preparation conditions. These parameter optimizations enable high detection sensitivity while keeping the manufacturing process feasible and repeatable.
