Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual creation of propagation channels is used for base station evaluation, then measurement precision is improved, but loss of time and use of energy increase
Solution Approach 1:
The patent uses a graphical user interface to display spatial frequency domain beam pattern analysis information as a visual representation copy of the actual beam patterns. This allows operators to evaluate base station performance by examining the displayed spatial frequency domain information rather than performing exhaustive manual measurements, thereby reducing evaluation time while maintaining analysis accuracy.
Solution Approach 2:
The patent introduces spatial frequency domain transformation as an intermediary method between physical propagation channel measurements and beam pattern analysis. By transforming measurement data into the spatial frequency domain through the GUI, the system provides an efficient intermediate representation that simplifies evaluation while preserving essential beam pattern characteristics.
2Measurement precision
If manual creation of propagation channels is used for base station evaluation, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The GUI displays spatial frequency domain beam pattern information as a visual copy that captures essential characteristics without requiring exhaustive computational processing. This visual representation allows operators to perform accurate beam pattern analysis with reduced computational energy expenditure compared to traditional manual propagation channel creation methods.
Solution Approach 2:
The patent transforms beam pattern data from the spatial domain to the spatial frequency domain, changing the parameter representation. This transformation enables more efficient analysis by operating in a domain where beam patterns can be visualized and evaluated with lower computational energy requirements while maintaining measurement precision.
3Device complexity
If comprehensive beam pattern analysis is performed, then device complexity increases, but ease of operation decreases
Solution Approach 1:
The GUI provides a simplified visual copy of complex spatial frequency domain beam pattern data that is easy for operators to interpret. Instead of requiring operators to navigate complex analysis tools, the system displays processed spatial frequency domain information in an intuitive graphical format, improving ease of operation while maintaining comprehensive analysis capabilities.
Solution Approach 2:
The graphical user interface acts as an intermediary layer between the complex beam pattern analysis modules and the operator. It translates complex spatial frequency domain data into intuitive visual representations, shielding operators from underlying system complexity while enabling comprehensive beam pattern evaluation.
