Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual RF spectrum analysis is performed by technicians, then measurement precision can be achieved, but the complexity of operation increases and requires expert knowledge
Solution Approach 1:
The system performs self-diagnosis by automatically analyzing RF spectrum data, identifying interference patterns, and generating diagnostic reports without requiring technician intervention for parameter adjustment or interpretation, thus resolving the contradiction between measurement precision and ease of operation
Solution Approach 2:
The patent replaces manual mechanical adjustment of spectrum analyzer parameters with automated digital signal processing algorithms that automatically detect and analyze RF interference, eliminating the need for expert knowledge while maintaining detection accuracy
2Ease of operation
If automated measurement is implemented, then ease of operation improves, but the complexity of information presentation increases overwhelming non-expert technicians
Solution Approach 1:
The system extracts only the most relevant diagnostic information from complex RF spectrum data, presenting simplified interference identification results to technicians while retaining full analytical capability in the background, thus resolving the contradiction between automation and information complexity
Solution Approach 2:
The patent applies different levels of information detail to different user needs, providing simplified views for non-expert technicians while maintaining access to comprehensive analytical data for experts, thereby resolving the information complexity issue while preserving ease of operation
3Productivity
If more antennas are installed to increase network capacity, then productivity improves, but the difficulty of detecting and measuring interference increases
Solution Approach 1:
The system introduces an automated analysis intermediary that processes RF spectrum data from multiple antennas, identifying interference patterns across the expanded network infrastructure without increasing the difficulty of detection for technicians, thus resolving the contradiction between network capacity and measurement difficulty
