Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed target or rotating target is selected during initial design, then the connection method between the target and accelerator can be simplified, but the compatibility between fixed target and rotating target is lost, limiting future apparatus updates
Solution Approach 1:
The patent designs a universal target mounting structure that can accommodate both fixed targets and rotating targets through the same interface. The base platform includes a standardized mounting interface and positioning mechanism that works with both target types, eliminating the need for different connection methods for different target types while maintaining structural simplicity.
Solution Approach 2:
The patent incorporates a movable and adjustable mounting structure that can adapt its configuration based on the target type installed. The base platform allows for positional adjustments and configuration changes to accommodate the different operational requirements of fixed versus rotating targets, enabling the system to dynamically adapt rather than requiring separate fixed designs for each target type.
2Ease of repair
If extensive disassembly is performed to replace targets, then target replacement can be achieved, but the operation time and disruption to the apparatus increase
Solution Approach 1:
The patent divides the target system into modular components that can be independently replaced. The target assembly is segmented from the main accelerator body through a standardized interface, allowing the target to be removed and replaced without disassembling the entire apparatus. This modular design enables quick target changes while maintaining the integrity of the main system.
Solution Approach 2:
The patent incorporates preliminary positioning features and pre-configured mounting interfaces that prepare the system for rapid target replacement. The base platform includes pre-positioned alignment features, standardized connection points, and accessible mounting mechanisms that are prepared in advance, allowing target replacement to proceed quickly without requiring complex alignment or extensive disassembly during the replacement operation.
3Adaptability or versatility
If the beam shaping device is extensively disassembled to accommodate both target types, then compatibility is achieved, but the device complexity and disassembly requirements increase
Solution Approach 1:
The beam shaping device is designed with a universal interface and standardized mounting structure that can accommodate both fixed and rotating targets without requiring extensive disassembly or modification. The base platform incorporates a universal connection system that maintains the same structural configuration regardless of which target type is installed, thereby achieving compatibility while preserving structural simplicity.
Solution Approach 2:
The patent introduces a base platform as an intermediary component between the accelerator and the target assembly. This base platform serves as a universal interface that handles the compatibility requirements, allowing both fixed and rotating targets to be mounted through the same structure without requiring the beam shaping device itself to be extensively modified or disassembled. The intermediary absorbs the complexity of adaptation.
