Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If frequencies are increased to increase data transmission throughput, then data transmission throughput is improved, but transmission loss increases
Solution Approach 1:
The patent changes the parameter of frequency selection by determining representative frequencies through segmented linear regression analysis. This allows the system to operate at higher frequencies for improved throughput while compensating for transmission loss through accurate power estimation and correction values specific to each frequency segment.
2Device complexity
If representative frequencies are not properly determined, then device complexity is reduced, but power estimation accuracy deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the frequency range into multiple segments and performing linear regression analysis separately for each segment. Representative frequencies are determined at segment boundaries, which simplifies the overall determination process while maintaining accurate power estimation across the entire frequency range.
Solution Approach 2:
The patent performs preliminary linear regression analysis to determine representative frequencies and correction values before actual power estimation is needed. These pre-calculated values are stored and reused, avoiding complex real-time calculations while ensuring accurate power estimation.
3Measurement precision
If more representative frequencies are used to improve power estimation accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent makes the number of representative frequencies dynamic by adjusting the segmentation based on error thresholds. The system automatically determines the optimal number of segments and representative frequencies needed to achieve acceptable accuracy, avoiding both over-complication and insufficient precision.
