Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional macrocell systems are used to provide wireless coverage, then coverage area is maintained, but bandwidth capability is insufficient to meet increased data demand
Solution Approach 1:
The patent divides the wireless coverage area into macrocells and multiple small cells (microcells and picocells). Each small cell provides high-bandwidth coverage for a limited area, while collectively they cover the entire service region. This segmentation allows the system to provide both high bandwidth capability and flexible coverage adaptation.
2Ease of operation
If electrical return paths are required for signal propagation, then signal stability is improved, but system flexibility and installation ease are reduced
Solution Approach 1:
The patent introduces a hybrid wave mode that acts as an intermediary between traditional electrical signals and electromagnetic waves. This hybrid wave propagates along the power line surface with electromagnetic field characteristics, eliminating the need for electrical return paths while maintaining signal stability through the guiding effect of the power line surface.
3Adaptability or versatility
If power lines are used as transmission media for guided waves, then infrastructure utilization is improved, but power consumption variations cause signal instability
Solution Approach 1:
The patent incorporates feedback mechanisms in the waveguide system to monitor and compensate for power consumption variations on the power lines. By detecting changes in the electrical environment and adjusting transmission parameters accordingly, the system maintains signal stability despite variations in power line load conditions.
