Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional wireless infrastructure is used to provide broadband access, then existing networks can be maintained, but bandwidth capability is insufficient to address increased demand from smartphones and data-intensive services
Solution Approach 1:
The patent segments the network infrastructure into macrocells for wide coverage and small cells (microcells and picocells) for targeted high-bandwidth areas. This segmentation allows the system to address bandwidth limitations by deploying additional small cell nodes without requiring complete infrastructure replacement, thereby improving overall network capacity and efficiency.
Solution Approach 2:
The patent transitions from traditional two-dimensional wireless propagation to three-dimensional guided wave transmission along physical structures. By binding electromagnetic waves to wires and building structures, the system creates additional transmission dimensions that bypass conventional bandwidth limitations of free-space wireless communication.
2Quantity of substance
If small cell deployment is pursued to provide additional mobile bandwidth, then bandwidth capability increases, but infrastructure complexity increases
Solution Approach 1:
The patent makes existing physical infrastructure (wires, building structures) serve dual purposes: their original function plus guiding electromagnetic waves for communication. This multi-functionality allows small cells to be deployed using already-present structures, reducing the need for dedicated new infrastructure and thereby lowering overall system complexity despite increased bandwidth capacity.
Solution Approach 2:
The guided wave system utilizes existing physical structures (wires, buildings) that are already present in the environment to provide transmission paths. These structures essentially serve themselves by simultaneously performing their original function and acting as waveguides, eliminating the need for separate dedicated transmission infrastructure and reducing deployment complexity.
3Ease of operation
If electromagnetic waves are transmitted through free space, then wireless communication is achieved, but propagation loss increases over long distances
Solution Approach 1:
The patent introduces physical structures (wires, building surfaces) as intermediaries to guide electromagnetic waves between transmitter and receiver. These intermediary structures bind the electromagnetic energy to their surfaces, preventing radiation loss into free space and enabling low-loss transmission over long distances while maintaining wireless communication capabilities.
4Reliability
If broadband access networks are enhanced to meet increasing data demands, then service quality improves, but network infrastructure requirements increase
Solution Approach 1:
The patent creates a dynamic network architecture where guided wave and traditional wireless modes can coexist and adapt to different service requirements. The system can dynamically select or combine transmission modes based on distance, environment, and service quality requirements, allowing reliable high-quality service without permanently complexifying the entire infrastructure.
