Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wireless communication systems are used to provide high bandwidth capability, then mobile data demand can be addressed, but signal loss and interference increase and electrical return paths are required
Solution Approach 1:
The patent replaces traditional electrical signal transmission through conductors with electromagnetic surface wave propagation along dielectric materials. This substitution eliminates the need for electrical return paths and reduces signal loss by utilizing the dielectric surface to guide electromagnetic energy rather than relying on conductive pathways susceptible to interference.
Solution Approach 2:
The patent introduces dielectric materials as intermediary structures that enable electromagnetic wave propagation. These dielectric surfaces act as mediators that guide and confine electromagnetic energy, allowing high-bandwidth communication without direct electrical contact or return paths, thereby reducing interference and signal loss.
2Adaptability or versatility
If broadband access networks are deployed to support voice, video and Internet services, then data access capability improves, but infrastructure complexity and signal interference increase
Solution Approach 1:
The patent enables dielectric structures to serve multiple functions: guiding electromagnetic surface waves for high-bandwidth communication, providing structural support, and eliminating the need for separate electrical return path infrastructure. This multi-functionality reduces overall infrastructure complexity while supporting diverse broadband services.
Solution Approach 2:
The patent extracts and eliminates the requirement for electrical return paths from the communication infrastructure. By using dielectric surface wave propagation, the system removes the complex electrical grounding and return path infrastructure traditionally required for broadband networks, simplifying deployment while maintaining service capability.
3Speed
If electromagnetic waves are used for wireless communication, then data transmission speed increases, but signal loss occurs without proper return paths
Solution Approach 1:
The patent ensures continuous electromagnetic energy propagation along the dielectric surface by maintaining consistent surface wave guidance. The dielectric material continuously confines and directs the electromagnetic energy, preventing signal loss that would occur in free-space propagation without return paths, while maintaining high transmission speeds.
Solution Approach 2:
The patent changes the propagation parameters by transitioning from conventional electromagnetic wave propagation requiring return paths to surface wave propagation along dielectric surfaces. This parameter change enables high-speed data transmission while reducing signal loss through the unique electromagnetic field confinement provided by the dielectric interface.
