Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple images of different magnifications and detector configurations are acquired for comprehensive object analysis, then the completeness of object study is improved, but the difficulty of comparing and relating these images increases
Solution Approach 1:
The patent merges multiple images acquired under different microscope settings (magnification, detector configuration, kinetic energy) into a single composite display. Each original image is represented as an overlay on the composite image, allowing simultaneous visualization and comparison of all images. This resolving means directly addresses the contradiction by combining multiple images into one unified view, improving completeness of analysis while eliminating the difficulty of comparing separate images.
Solution Approach 2:
The patent introduces a composite image as an intermediary representation that mediates between multiple original images. The composite image serves as a reference framework that shows the spatial relationships and relative positions of features across all original images. This intermediary structure enables easy comparison and correlation of features from different imaging conditions without requiring direct comparison of multiple separate images.
2Adaptability or versatility
If images from different detector configurations (SE, BSE, EDX) are used to reveal different object characteristics, then the comprehensiveness of analysis is improved, but the complexity of determining how images are related increases
Solution Approach 1:
The patent combines images from different detector configurations (secondary electron detector, backscattered electron detector, energy-dispersive spectrometer) into a single composite display. Each detector's image is overlaid on the composite image with visual indicators showing which detector was used. This allows comprehensive analysis of topographic features, compositional information, and elemental distribution simultaneously, while the unified display eliminates the complexity of determining relationships between separate images from different detectors.
3Measurement precision
If a user manually browses through multiple images to identify object features and select locations for further imaging, then thorough analysis is achieved, but the time required for analysis increases
Solution Approach 1:
The patent merges multiple images into a single composite display that provides an overview of all imaged regions and their relationships. Users can identify object features and select locations for further imaging by viewing the composite image, which shows the spatial context of all features across different magnifications and detector settings. This eliminates the need to manually browse through multiple separate images, dramatically reducing analysis time while maintaining thoroughness through the comprehensive view provided by the composite image.
