Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wireless infrastructure is used to provide mobile bandwidth, then coverage area is maintained, but bandwidth capacity is insufficient to address increased data demand
Solution Approach 1:
The patent transitions from traditional free-space wireless propagation to guided wave propagation along transmission media surfaces, representing a dimensional change in the propagation path. This allows electromagnetic energy to be confined and directed along wires and dielectric surfaces, effectively adding a new dimension to wireless communication and enabling higher bandwidth capacity through multiple parallel transmission paths.
Solution Approach 2:
The patent introduces transmission media (wires and dielectric surfaces) as intermediary structures to guide electromagnetic wave propagation. These intermediaries confine the electromagnetic energy, reducing dispersion and enabling more efficient data transmission with higher bandwidth capacity compared to unguided wireless propagation.
2Loss of energy
If guided wave communication is used to reduce propagation losses, then transmission distance is extended, but device complexity increases due to coupling apparatus
Solution Approach 1:
The patent employs self-service principles where existing infrastructure elements (wires and dielectric surfaces) automatically serve as transmission media without requiring additional active components. The coupling apparatus utilizes the natural electromagnetic properties of these existing structures, allowing them to guide waves without needing external power or control systems, thereby reducing overall system complexity.
Solution Approach 2:
The coupling apparatus is designed to work with multiple types of transmission media (different wire configurations and dielectric surfaces), providing universal functionality. This multi-functionality reduces the need for media-specific coupling devices, simplifying the overall system architecture despite the added capability of guided wave transmission.
3Productivity
If millimeter-wave frequencies are used to increase bandwidth capacity, then data transmission rate is improved, but propagation loss increases
Solution Approach 1:
The patent uses transmission media surfaces as intermediaries to guide millimeter-wave propagation. This guidance mechanism confines the high-frequency electromagnetic energy, preventing the typical free-space path loss that would otherwise limit millimeter-wave transmission distance. The intermediary structures enable millimeter-waves to propagate efficiently over longer distances by keeping the energy concentrated along the transmission path.
