Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional macrocell base stations are used to provide broadband access, then coverage area is large, but bandwidth capability is insufficient to meet increasing data demand
Solution Approach 1:
The patent segments the macrocell coverage area into multiple small cell zones, each served by its own base station. This allows the overall network to maintain large coverage while each individual cell provides high bandwidth capability, resolving the contradiction between coverage area and bandwidth capability.
2Productivity
If wireless infrastructure is expanded to meet data demand, then bandwidth capability increases, but propagation loss increases
Solution Approach 1:
The patent transitions from traditional two-dimensional ground-based wireless propagation to three-dimensional propagation by launching electromagnetic waves into the atmospheric layer above the ground. This dimensional change enables signals to bypass ground obstacles and reduce propagation loss while maintaining high data transmission capacity.
Solution Approach 2:
The patent introduces a dielectric waveguide structure as an intermediary medium to guide electromagnetic waves through the atmosphere. This waveguide mediates between the transmitter and receiver, enabling efficient signal propagation with reduced loss over long distances while maintaining high bandwidth capability.
3Loss of energy
If guided wave transmission is used to reduce propagation loss, then transmission efficiency improves, but device complexity increases
Solution Approach 1:
The patent designs the dielectric waveguide structure to serve multiple functions simultaneously: it guides electromagnetic waves, provides structural support, and defines the transmission path. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving reduced propagation loss.
