Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional wireless infrastructure is used to provide broadband access, then existing wireless networks can serve current devices, but propagation loss increases and transmission distance is limited
Solution Approach 1:
The patent introduces a physical transmission medium (wire or dielectric material) as an intermediary to guide electromagnetic waves. This mediator binds the electromagnetic energy to the structure, enabling low-loss propagation over long distances without relying on traditional wireless broadcast mechanisms.
Solution Approach 2:
The patent changes the propagation parameter from free-space wireless transmission to guided transmission along a physical structure. By transforming the electromagnetic wave into a guided mode bound to a wire or dielectric, the system achieves fundamentally different propagation characteristics with reduced loss and extended range.
2Object-affected harmful factors
If electromagnetic waves are transmitted through free space, then wireless communication is achieved, but interference from other signals increases
Solution Approach 1:
The physical transmission medium acts as a spatial filter and intermediary that isolates the electromagnetic signal from the free-space environment. This guidance structure prevents other signals from coupling into the transmission path, thereby eliminating interference while preserving wireless communication functionality at the endpoints.
Solution Approach 2:
The patent extracts the electromagnetic energy from the common free-space domain and confines it to a dedicated guided path. By separating the signal from the shared wireless medium, the system eliminates interference from other wireless signals while maintaining the ability to communicate wirelessly over distance.
