Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If commercial metallurgical bright field microscope is used to image the Li|SSE interface, then microstructural information can be obtained, but chemical changes of the interface cannot be detected
Solution Approach 1:
The patent combines bright field imaging, fluorescence imaging, and Raman mapping into a single multimodal imaging system. This integration allows simultaneous acquisition of microstructural (bright field), chemical (fluorescence, Raman) information from the Li|SSE interface, resolving the contradiction by merging multiple imaging capabilities into one unified platform that provides both microstructural and chemical characterization.
Solution Approach 2:
The imaging system is designed with multi-functionality to perform various imaging modes (bright field, fluorescence, Raman mapping) through a single device. The system can switch between different imaging techniques to provide comprehensive characterization of the interface, making the device universal for both microstructural and chemical analysis without requiring separate instruments.
2Loss of information
If multiple imaging modes are integrated to provide comprehensive interface characterization, then both microstructural and chemical information can be obtained, but the device complexity increases
Solution Approach 1:
The patent merges bright field, fluorescence, and Raman mapping capabilities into a single integrated imaging system. By combining these modalities, the system achieves comprehensive interface characterization while managing device complexity through unified optical paths and coordinated control mechanisms.
Solution Approach 2:
The system employs dynamic control of optical components (mirrors, beam splitters) to switch between different imaging modes. This dynamic reconfiguration allows the system to adapt its imaging capabilities based on the specific characterization needs, providing comprehensive information while maintaining operational flexibility and managing system complexity through programmable control.
