Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual inquiry and entry of channel numbers and center frequencies is used, then the process is simple to implement, but the detection time and effort increase significantly
Solution Approach 1:
The detection system automatically performs spectrum analysis, peak detection, and channel identification without human intervention. The system self-services by receiving the spectrum, automatically analyzing it to detect peaks corresponding to mobile channels, and generating a list of channel numbers and center frequencies, thereby eliminating manual inquiry and entry operations
Solution Approach 2:
The manual mechanical process of inquiring and entering channel data is replaced by an automated electronic detection system that uses spectrum analysis and peak detection algorithms to automatically identify mobile channels and their parameters, significantly reducing detection time
2Device complexity
If manual entry of channel information is used, then the system complexity is low, but the productivity decreases
Solution Approach 1:
The system automatically performs all detection operations including spectrum reception, analysis, peak detection, and channel list generation without requiring manual operations, thereby significantly improving productivity while maintaining manageable system complexity through automated processes
Solution Approach 2:
The detection system continuously performs spectrum analysis and peak detection to rapidly identify all available mobile channels in a short time, enabling continuous and efficient detection operations that improve productivity compared to intermittent manual entry processes
3Reliability
If frequent manual updates of channel information are performed, then the information remains current, but the effort and time consumption increase
Solution Approach 1:
The detection system automatically and frequently updates the list of available mobile channels by continuously performing spectrum analysis and peak detection, ensuring information remains current without requiring manual updates, thereby maintaining reliability while reducing update effort and time consumption
Solution Approach 2:
The system proactively and frequently detects and updates channel information before manual updates would be needed, ensuring that channel data is always current and ready for use in interference analysis and roaming coverage determination without requiring reactive manual intervention
