Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face challenges in providing high bandwidth and efficient data transmission, especially with the increasing demand from smartphones and other portable devices, as traditional wireless infrastructure struggles to manage increased data usage and requires additional bandwidth, and existing systems rely on electrical return paths for signal propagation.
Innovation Solution
A guided wave communication system that uses electromagnetic waves bound to a transmission medium, such as wires or dielectric materials, to propagate signals without the need for an electrical return path, allowing for efficient data transmission over long distances with reduced loss, using couplers and transceivers to launch and receive guided waves at millimeter-wave frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wireless infrastructure is used to provide broadband access, then coverage area is large, but bandwidth capability is insufficient for increased data demand
Solution Approach 1:
The patent segments the transmission medium into discrete sections with coupled resonators, allowing each segment to contribute to overall bandwidth while maintaining extended coverage through the distributed structure
Solution Approach 2:
The patent transitions from traditional wireless 3D space propagation to guided wave transmission along a 1D transmission medium structure, enabling higher bandwidth capacity while maintaining spatial coverage through the physical extent of the guided wave path
2Productivity
If small cell deployment is pursued to provide additional mobile bandwidth, then bandwidth capacity increases, but infrastructure complexity increases
Solution Approach 1:
The transmission medium structure serves multiple functions simultaneously: it provides signal transmission, acts as a resonant enhancement structure, and enables both covered and uncovered mode propagation, eliminating the need for separate small cell infrastructure
Solution Approach 2:
The patent merges the functions of multiple small cells into a single integrated guided wave transmission system, combining signal transmission, resonance enhancement, and coverage extension into one unified infrastructure
3Reliability
If electrical return paths are used for signal propagation, then signal transmission is reliable, but propagation loss increases over long distances
Solution Approach 1:
The patent extracts the signal from the conventional electrical return path and transitions to guided wave propagation in the uncovered mode, eliminating the need for closed-loop electrical circuits and reducing resistive losses
Solution Approach 2:
The patent replaces the electrical conduction mechanism with guided electromagnetic wave propagation, substituting the electrical field-based transmission with a hybrid electro-magnetic mode that experiences lower attenuation over long distances
4Loss of energy
If guided waves are launched in uncovered mode, then propagation loss is reduced, but interference from external sources increases
Solution Approach 1:
The patent employs periodic resonators coupled to the transmission medium that create frequency-selective response, allowing the system to operate at specific resonant frequencies where signal strength is maximized and external interference at non-resonant frequencies is naturally rejected
Solution Approach 2:
The resonant structure provides frequency-selective feedback that reinforces the desired signal at resonant frequencies while attenuating external interference, creating a self-regulating system that maintains signal integrity
