Engineering Contradiction Analysis
1Measurement precision
If original measured parameters are stored and used for correction, then measurement accuracy can be improved, but storage capacity and computational power requirements increase significantly
Solution Approach 1:
The patent extracts only the essential averaged parameters from the complete set of original measured parameters. Instead of storing and processing all raw measurement data, the system calculates averaged values for key parameters (flow rate, temperature, pressure) over predetermined time intervals, storing only these averaged values for correction purposes while discarding the detailed original data.
Solution Approach 2:
The patent inverts the traditional correction approach by first averaging the parameters and then correcting the averaged values, rather than correcting each individual original measurement and then averaging. This inversion allows correction to be performed on a reduced data set while maintaining measurement accuracy.
2Measurement precision
If original measured parameters are used for correction, then measurement accuracy can be improved, but computational effort and system complexity increase
Solution Approach 1:
The system extracts only the necessary averaged parameters for correction, eliminating the need to process and store complete raw data sets. This extraction approach simplifies the computational workload while maintaining the essential information needed for accurate measurement correction.
Solution Approach 2:
The patent performs preliminary averaging of measured parameters before correction is applied. By pre-calculating averaged values for predetermined time intervals, the system reduces the computational complexity of the correction process, as corrections are then applied to already-averaged data rather than individual measurements.
3Measurement precision
If measured parameters are corrected in real-time, then measurement accuracy is improved, but data processing time and computational resources increase
Solution Approach 1:
The system performs preliminary averaging of measured parameters over predetermined time intervals before correction is applied. This pre-processing step organizes the data in advance, allowing corrections to be efficiently applied to averaged values rather than processing individual measurements in real-time, thus reducing data processing time.
Solution Approach 2:
The patent implements periodic averaging of measured parameters at predetermined time intervals. This periodic approach allows the system to process data in manageable batches rather than continuously processing every individual measurement, reducing real-time computational demands while maintaining measurement accuracy through regular correction cycles.
