Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional measuring devices analyze component signals one by one using analog mixing and sequential processing, then the device complexity is reduced and ease of operation is improved, but the measurement precision and ability to detect interactions between component signals deteriorate
Solution Approach 1:
The patent replaces the conventional analog mixing and sequential processing mechanism with a digital signal processing system. The measuring device digitizes the input signal and uses digital mixers and filters to analyze multiple component signals simultaneously, eliminating the need for sequential analog processing while improving measurement precision and interaction detection capability.
Solution Approach 2:
The patent transitions from time-sequential signal analysis to simultaneous multi-frequency analysis by introducing a digital signal processing dimension. The system can process multiple component signals at the same time across different frequency bands, adding a temporal and spectral dimension to the measurement capability.
2Ease of operation
If conventional measuring devices use sequential analysis of component signals, then the ease of operation is improved and device complexity is reduced, but the productivity and measurement time deteriorate
Solution Approach 1:
The patent implements continuous simultaneous processing of multiple component signals through digital signal processing. The measuring device continuously analyzes all component signals across different frequency bands without interruption or sequential switching, maintaining continuous useful action throughout the measurement process and significantly improving productivity.
Solution Approach 2:
The patent creates a universal measuring system that can simultaneously analyze multiple types of component signals from different communications standards (GSM, UMTS, LTE) within a single measurement process. The digital signal processing architecture provides multi-functionality, allowing the device to handle various signal types concurrently without requiring separate analysis procedures.
3Device complexity
If conventional measuring devices analyze signals component-by-component sequentially, then the device complexity is reduced, but the ability to detect interactions between component signals from different communications standards deteriorates
Solution Approach 1:
The patent uses parameter changes in the digital signal processing domain to adaptively analyze different component signals. The system can dynamically adjust digital filter characteristics, mixing frequencies, and analysis parameters to accommodate various communications standards (GSM, UMTS, LTE) while maintaining the ability to detect interactions between signals of different types.
Solution Approach 2:
The patent creates digital copies of the input signal at different frequency bands through digital mixing and filtering. By generating multiple digital composite test signals representing different component signals, the system can simultaneously analyze and compare signals from different communications standards without physical separation, improving adaptability while managing complexity through digital rather than physical duplication.
