Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light source systems lack redundancy and fail to maintain efficient light output in case of accelerator module failures or anomalous conditions.
Innovation Solution
A light source system that includes multiple accelerator modules, splitters, recombiners, and radiator modules, capable of operating in both normal and backup modes. The system splits electron beams into multiple paths, ensuring equal path length differences and allowing for redundancy in light output generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single accelerator module is used in the light source system, then the device complexity is reduced, but the reliability deteriorates because the system fails to maintain efficient light output in case of accelerator module failures
Solution Approach 1:
The light source system is divided into multiple independent accelerator modules (first accelerator module, second accelerator module, etc.), each capable of independently generating electron beams. This segmentation allows the system to maintain functionality even if one module fails, thereby improving reliability while managing complexity through modular design
Solution Approach 2:
The system dynamically changes operational parameters by switching between different accelerator modules based on their availability and performance. When one accelerator module fails, the system adjusts by activating backup modules and reconfiguring the electron beam paths through splitters and recombiners to maintain the required light output parameters
2Reliability
If multiple accelerator modules are implemented with redundancy, then the reliability is improved, but the device complexity increases due to additional components like splitters and recombiners
Solution Approach 1:
Backup accelerator modules are pre-configured and ready to activate immediately upon failure of primary modules. The splitter and recombiner components are pre-arranged to automatically redirect electron beams when failures occur, eliminating the need for complex real-time decision-making and reducing operational complexity
Solution Approach 2:
The splitter and recombiner components serve multiple functions: they divide electron beams from multiple accelerator modules into separate paths for individual radiator modules, and they also enable reconfiguration for backup operation by redirecting beams from a single accelerator module to multiple radiator modules. This multi-functionality reduces the need for dedicated components for each mode
3Reliability
If electron beams are split into multiple paths for redundant radiator modules, then the reliability is improved, but the manufacturing precision requirements increase to ensure equal path length differences
Solution Approach 1:
The beam paths are designed to have equal path length differences, creating equipotential conditions for electron beam propagation. This ensures that electrons traveling through different paths experience equivalent optical conditions, maintaining coherent light output and reducing the impact of manufacturing tolerances on overall system performance
Solution Approach 2:
The system incorporates adjustable components in the beam paths that allow dynamic compensation for path length differences. These adjustable elements enable fine-tuning during system operation to maintain equal path lengths despite manufacturing variations, thereby reducing stringent manufacturing precision requirements
