Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a wireless reception terminal detects interference waves using carrier sensing and determines illegal radio waves, then interference information can be transmitted to a control station, but the factor of quality degradation cannot be identified
Solution Approach 1:
The detection process is segmented into multiple functional units: a reception unit that receives radio waves, a spectrum generation unit that creates spectra from the received waves, a determination unit that identifies degradation factors by comparing spectra against criteria, and an output unit that reports results. This segmentation allows each unit to focus on a specific aspect of detection, enabling identification of quality degradation factors while maintaining comprehensive interference detection capabilities.
2Measurement precision
If a maintenance worker uses a dedicated measurement instrument to search for quality degradation factors, then accurate measurement can be performed, but specialized knowledge and complex equipment are required
Solution Approach 1:
The wireless reception terminal is designed to perform multiple functions: it not only detects interference waves and transmits information to control stations but also generates spectra, determines quality degradation factors, and outputs identification results. This multi-functionality eliminates the need for separate dedicated measurement instruments, allowing the terminal to accurately measure quality degradation factors while reducing device complexity and eliminating the requirement for specialized maintenance equipment.
3Object-generated harmful factors
If carrier sensing is performed in a frequency band to detect illegal radio waves, then interference waves can be detected, but the quality of received radio waves cannot be maintained
Solution Approach 1:
The system continuously monitors the received radio waves, generates spectra in real-time, compares them against predetermined criteria, and identifies quality degradation factors. This feedback mechanism allows the system to detect when radio wave quality deteriorates due to interference and provide information about the degradation factors, enabling corrective actions to maintain reliable communication while continuing to detect harmful interference waves.
