Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the target is fixed to the derivation portion for radioactive isotope production, then the manufacturing process is simple, but the target cannot be easily replaced and the particle beam current stability is affected
Solution Approach 1:
The target is designed to be movable relative to the derivation portion through a moving mechanism, allowing it to transition between a first position (for production) and a second position (for replacement). This dynamic configuration enables both efficient production and easy target replacement without compromising either function
Solution Approach 2:
The system separates the target from the derivation portion, allowing independent movement and replacement. The target can be detached and replaced without affecting the accelerator structure, improving both productivity and adaptability
2Reliability
If the target is electrically connected to the accelerator for production, then the electrical connection is simple, but electrical discharge occurs affecting current stability
Solution Approach 1:
An electrical insulation member is introduced as an intermediary between the target and the derivation portion. This insulation member prevents direct electrical contact, eliminating discharge issues while maintaining the functional relationship through mechanical positioning and movement mechanisms
Solution Approach 2:
The electrical connection is replaced with a mechanical positioning system. The target's position relative to the derivation portion is controlled mechanically through the moving mechanism, eliminating the need for direct electrical contact and associated insulation complexity
3Manufacturing precision
If manual target handling is used, then the device structure is simple, but the manufacturing yield and precision are reduced
Solution Approach 1:
The system enables automated target handling through the moving mechanism and positioning system, which can autonomously move the target between positions and facilitate replacement without manual intervention, improving precision while keeping the automated system relatively simple
