Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wireless communication systems are used to provide high bandwidth, then data transmission capacity increases, but infrastructure complexity and requirement for electrical return paths increase
Solution Approach 1:
The patent extracts the electrical return path requirement from the communication system by using guided electromagnetic waves that propagate along a single conductor (power line) without needing a return path. The guided waves are bound to the power line and can return to the source through the ground or through the source's internal impedance, eliminating the need for dedicated return conductors and reducing infrastructure complexity while maintaining high data transmission capacity.
2Ease of operation
If electromagnetic waves are propagated through free space, then wireless communication is achieved, but signal loss increases over long distances
Solution Approach 1:
The patent introduces guided electromagnetic waves as an intermediary between traditional free-space wireless communication and wired communication. These guided waves are bound to the power line and follow the conductor's path, significantly reducing propagation loss compared to free-space waves while maintaining wireless communication capabilities at the endpoints. The power line acts as a waveguide, efficiently guiding the electromagnetic energy over long distances.
3Productivity
If complex infrastructure is deployed to provide broadband access, then bandwidth capability increases, but system complexity and deployment difficulty increase
Solution Approach 1:
The patent makes power lines multi-functional by enabling them to serve both their traditional purpose of delivering electrical power and as transmission media for high-bandwidth data communication. This eliminates the need for separate communication infrastructure in many cases, as existing power line infrastructure can be utilized for both power delivery and high-speed data transmission, significantly reducing deployment difficulty and cost while providing broadband capability.
