Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only final spectrum data is output without intermediate data, then the measurement process is simplified, but the user cannot verify the correctness of the analysis results
Solution Approach 1:
The patent segments the analysis process into multiple stages and outputs intermediate results at each stage. Specifically, it generates and displays intermediate data including pixel-wise analysis results, cluster assignment results, and spectrum data, allowing users to verify each step of the analysis process while maintaining the overall simplicity of the measurement workflow
Solution Approach 2:
The patent implements feedback by displaying intermediate analysis results to users during the measurement process. The system outputs pixel analysis results, cluster assignments, and spectrum data that provide feedback on the analysis progress and correctness, enabling users to verify results at each stage without complicating the overall operation
2Measurement precision
If spectrum data for the entire colorimetric region is captured, then comprehensive analysis is achieved, but the data processing time increases
Solution Approach 1:
The patent divides the colorimetric region into multiple pixels and processes each pixel independently through the analysis workflow. By segmenting the region and using parallel processing techniques, the system maintains comprehensive analysis of all pixels while reducing overall processing time compared to sequential analysis of the entire region
Solution Approach 2:
The patent performs analysis on all pixels in the colorimetric region (excessive action) but optimizes the process by calculating only the necessary spectral parameters for each pixel. This approach ensures comprehensive coverage while avoiding unnecessary calculations that would increase processing time
