Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional spectrum analyzers are used without enhanced display features, then device complexity is reduced, but user workload increases and productivity decreases
Solution Approach 1:
The system automatically performs signal pattern recognition, template matching, and overlay operations without requiring manual user intervention. The spectrum analyzer self-adjusts display parameters and automatically identifies signal patterns by comparing them against stored templates, eliminating the need for users to manually manipulate data or adjust display settings.
Solution Approach 2:
Signal pattern templates are pre-generated and stored in the system before actual spectrum analysis occurs. These templates contain characteristic patterns of known signals, allowing the system to quickly match and identify signals during operation without requiring real-time complex processing or manual setup.
2Measurement precision
If signal pattern templates are overlaid on detected signals, then pattern matching precision is improved, but device complexity increases
Solution Approach 1:
The system creates simplified template representations of known signal patterns and stores them as reference copies. During analysis, these template copies are overlaid on detected signals to identify matches, avoiding the need for complex real-time analysis while maintaining high precision through direct pattern comparison.
3Productivity
If automated signal pattern recognition is implemented, then productivity increases, but ease of operation decreases due to system complexity
Solution Approach 1:
The automated system performs all signal pattern recognition and identification operations autonomously without requiring user configuration or intervention. The system self-manages template selection, pattern matching, and result display, maintaining high productivity while keeping the user interface simple through automatic operation.
