Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the output power of the Wi-Fi system is increased to enlarge service coverage, then the WLAN service coverage area is improved, but the interference with WiMAX downlink signal quality increases
Solution Approach 1:
The patent implements dynamic power adjustment by continuously monitoring WiMAX downlink signal quality (CINR) and adaptively changing Wi-Fi output power levels. The system transitions from static power settings to dynamic control, adjusting power in real-time based on received signal conditions to balance coverage area and interference mitigation.
Solution Approach 2:
The patent establishes a feedback mechanism where the WiMAX downlink signal quality (CINR) is continuously monitored and fed back to control the Wi-Fi output power. When CINR exceeds a threshold, the system increases Wi-Fi power to expand coverage; when CINR falls below the threshold, power is reduced to protect WiMAX signal quality, creating a closed-loop control system.
2Object-affected harmful factors
If the output power of the Wi-Fi system is reduced to minimize interference with WiMAX, then the WiMAX downlink signal quality is improved, but the WLAN service coverage area is reduced
Solution Approach 1:
The system dynamically adjusts Wi-Fi output power based on real-time WiMAX signal conditions rather than using fixed low power settings. By monitoring CINR and adapting power levels accordingly, the system can temporarily increase coverage when WiMAX conditions permit, maximizing WLAN performance without permanently compromising WiMAX quality.
Solution Approach 2:
The patent changes the power output parameter of the Wi-Fi system based on the CINR parameter of the WiMAX downlink signal. By establishing a relationship between these two parameters and using threshold-based control, the system optimizes the power parameter to achieve the desired balance between coverage area and interference reduction.
3Stability of the object's composition
If fixed maximum power is set for Wi-Fi to ensure WiMAX stability, then the WiMAX downlink signal stability is improved, but the WLAN service coverage and data rate are limited
Solution Approach 1:
The patent replaces fixed power settings with dynamic power adjustment that responds to changing WiMAX signal conditions. This allows the Wi-Fi system to operate at higher data rates when WiMAX conditions are good (high CINR) while maintaining stability when conditions deteriorate, thereby improving overall WLAN productivity without compromising WiMAX stability.
Solution Approach 2:
The system uses parameter changes in Wi-Fi output power based on CINR threshold comparisons to optimize WLAN productivity. By adjusting the power parameter dynamically rather than fixing it, the system can achieve higher data rates during periods of good WiMAX signal quality while maintaining stability requirements.
