Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If flicker values are measured for multiple measurement regions under multiple measurement conditions, then the evaluation of flicker unevenness becomes more comprehensive, but the amount of data to be managed increases
Solution Approach 1:
The patent segments the measurement data by organizing it into distinct measurement conditions (first measurement condition, second measurement condition, etc.), with each condition containing flicker values for multiple measurement regions. This segmentation allows comprehensive evaluation across different conditions while managing data through structured division.
Solution Approach 2:
The patent introduces an intermediary data structure that links measurement conditions with flicker values of measurement regions. This intermediary organization enables efficient management and retrieval of data without requiring direct handling of the full dataset, facilitating comprehensive evaluation while maintaining data manageability.
2Measurement precision
If comprehensive flicker data under multiple conditions is collected, then the evaluation of flicker unevenness becomes more accurate, but the complexity of data management increases
Solution Approach 1:
The patent segments comprehensive flicker data into organized groups by measurement condition, where each condition contains structured information about measurement regions and their corresponding flicker values. This segmentation reduces management complexity while preserving evaluation accuracy.
Solution Approach 2:
The patent organizes data by adding a dimensional structure that associates flicker values with both measurement regions and measurement conditions. This multi-dimensional organization enables accurate evaluation across multiple conditions while simplifying management through structured categorization.
