Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct electrical contact is made with wires for signal transmission, then reliable electrical connection is achieved, but installation complexity and transmission losses increase
Solution Approach 1:
The patent introduces a coupler as an intermediary device that magnetically couples to the wire without direct electrical contact. The coupler includes a magnetic core with windings that create magnetic fields to transfer signals, acting as a mediator between the signal source and the power line while avoiding direct electrical connection complexities
Solution Approach 2:
The patent replaces direct electrical contact (mechanical connection) with magnetic coupling. Instead of physically connecting electrodes to wires, the system uses magnetic fields generated by the coupler's windings to transfer signals, substituting a mechanical electrical connection system with a field-based magnetic coupling system
2Loss of information
If direct electrical contact is made with wires, then signal transmission is achieved, but transmission losses increase
Solution Approach 1:
The coupler serves as a magnetic intermediary that transfers signals through magnetic coupling rather than direct electrical contact. This reduces transmission losses by avoiding contact resistance and electrical interference while maintaining signal integrity through controlled magnetic field interaction
Solution Approach 2:
The patent substitutes direct electrical contact with magnetic field-based signal transfer. This eliminates sources of transmission loss associated with electrical contacts such as resistance, oxidation, and arcing, while maintaining reliable signal transmission through the magnetic coupling mechanism
3Productivity
If existing wireless infrastructure is used, then current bandwidth is maintained, but higher bandwidth capability is insufficient
Solution Approach 1:
The patent creates a universal communication system that can transmit signals over existing power line infrastructure. The coupler design allows the system to adapt to different wire configurations and locations, making the network infrastructure versatile and multi-functional by utilizing existing electrical wiring for both power and data transmission
Solution Approach 2:
The system changes the transmission medium from traditional wireless radio frequency to guided electromagnetic waves along conductors. This parameter change enables higher bandwidth capability by utilizing the power line infrastructure as a transmission medium, overcoming the bandwidth limitations of existing wireless infrastructure

Data Source
AI summary
A dielectric waveguide coupling system for launching and extracting guided wave communication transmissions from a wire. At millimeter-wave frequencies, wherein the wavelength is small compared to the macroscopic size of the equipment, transmissions can propagate as guided waves guided by a strip of dielectric material. Unlike conventional waveguides, the electromagnetic field associated with the dielectric waveguide is primarily outside of the waveguide. When this dielectric waveguide strip is brought into close proximity to a wire, the guided waves decouple from the dielectric waveguide and couple to the wire, and continue to propagate as guided waves about the surface of the wire.
