Engineering Contradiction Analysis
1Measurement precision
If the number of measurement points on the measurement surface is increased to improve estimation accuracy of the measurement target field intensity distribution, then the estimation accuracy is improved, but the time required for the radiant interference wave test becomes longer
Solution Approach 1:
The patent divides the measurement surface into multiple regions and sets measurement points only in specific regions where the field intensity is expected to be high or vary significantly. This segmentation approach reduces the total number of measurement points while maintaining estimation accuracy in critical areas, thereby reducing test time without sacrificing overall accuracy.
Solution Approach 2:
The patent applies different measurement point densities to different regions of the measurement surface. Regions with higher field intensity or greater variation receive more measurement points, while regions with lower field intensity receive fewer points. This local quality approach optimizes the distribution of measurement points to achieve accurate estimation with fewer total measurements.
2Measurement precision
If a broad frequency band is measured to improve the accuracy of radiant interference wave testing, then the comprehensiveness of the test is improved, but the time required for measurement increases
Solution Approach 1:
The patent performs preliminary analysis to identify frequency bands that are most likely to contain significant radiant interference wave emissions based on the test piece characteristics and previous measurement data. By focusing measurements on these identified frequency bands, the patent achieves comprehensive testing of critical frequencies while reducing measurement time in less relevant frequency ranges.
