Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the mobile WiFi device uses the same channel for both uplink and downlink, then the device complexity is reduced, but service interruption occurs when switching channels
Solution Approach 1:
The patent divides the communication channels into separate uplink and downlink channels operating on different frequencies. This segmentation allows independent channel switching without service interruption, resolving the contradiction between simplified channel management and service continuity.
Solution Approach 2:
The patent implements dynamic channel switching where the uplink and downlink channels can be independently adjusted based on network conditions. This dynamic approach maintains service continuity while managing channel resources efficiently, overcoming the limitation of fixed same-channel operation.
2Reliability
If the mobile WiFi device switches to a different channel for downlink, then service interruption is avoided, but interference between channels increases
Solution Approach 1:
The patent introduces frequency separation as an intermediary mechanism between uplink and downlink channels. By operating on different frequencies, the system reduces mutual interference while maintaining service continuity, effectively mediating the conflict between reliability and interference.
Solution Approach 2:
The patent changes the frequency parameter of the downlink channel relative to the uplink channel. This parameter change enables independent channel switching without interference, resolving the contradiction between service continuity and channel interference.
3Object-affected harmful factors
If the mobile WiFi device reduces transmit power to minimize interference, then channel interference decreases, but communication range is reduced
Solution Approach 1:
The patent employs periodic transmit power adjustment combined with channel switching. By periodically adapting power levels and utilizing frequency diversity, the system minimizes interference while maintaining adequate communication range through temporal and spectral resource management.
Solution Approach 2:
The patent transitions from single-dimensional power control to multi-dimensional resource management by introducing frequency as an additional dimension. This allows interference reduction through frequency separation while maintaining range through optimized power allocation across multiple dimensions.
