Engineering Contradiction Analysis
1Volume of moving object
If traditional waveguide connection technologies are used, then reliable signal transmission is achieved, but space requirements increase
Solution Approach 1:
The patent merges the connecting element with the waveguide structures themselves. The first waveguide includes a first connecting section with a first contact surface, and the second waveguide includes a second connecting section with a second contact surface. These integrating connecting sections eliminate the need for separate connecting elements, reducing space while maintaining reliable capacitive coupling for signal transmission
Solution Approach 2:
The patent introduces an intermediary capacitive coupling mechanism between the two waveguides. The connecting sections create a capacitive interface that enables high-frequency signal transmission without direct galvanic contact, allowing compact integration while preserving signal integrity through the capacitive coupling field
2Device complexity
If separate connecting elements are used, then waveguide connection is achieved, but device complexity increases
Solution Approach 1:
The connecting functionality is merged directly into the waveguide bodies. The first waveguide incorporates a first connecting section with a first contact surface, and the second waveguide incorporates a second connecting section with a second contact surface. This integration eliminates separate connecting elements, simplifying the overall device structure while ensuring reliable signal transmission through the integrated capacitive interface
