Engineering Contradiction Analysis
1Speed
If optical communication technology is used for high-speed communication, then communication speed is improved, but cost increases and reliability decreases due to connection accuracy requirements
Solution Approach 1:
The patent changes the operating frequency parameter to millimeter wave range (30-300 GHz), enabling high-speed communication while using robust waveguide connections instead of fragile optical connectors, thus improving reliability
Solution Approach 2:
The patent replaces the optical communication system with an electromagnetic waveguide system, substituting the mechanical precision requirements of optical connectors with the more robust mechanical waveguide connections that are less sensitive to alignment errors
2Speed
If optical communication technology is used for high-speed communication, then communication speed is improved, but cost increases due to expensive transmission/reception units
Solution Approach 1:
The patent employs relatively inexpensive waveguide components and connectors that can be manufactured at lower cost compared to optical transmission/reception units, making high-speed communication more economically viable
Solution Approach 2:
By operating in the millimeter wave frequency range, the patent enables high-speed communication using established electromagnetic waveguide technology rather than requiring expensive optical communication infrastructure
3Ease of manufacture
If metal wire transmission methods are used for short-distance communication, then cost is reduced, but communication speed decreases and reliability is insufficient for high-definition video
Solution Approach 1:
The patent transitions from low-frequency electrical signals in metal wires to high-frequency electromagnetic waves in waveguides, enabling communication speeds of several tens of Gbps while maintaining relative cost-effectiveness through established waveguide manufacturing techniques

AI summary
A connection structure of a waveguide includes a rod-like dielectric, and an outer conductor. A three-dimensional component includes a connection surface, an insertion hole, and a corner which forms an opening edge of the insertion hole over an entire circumference on the connection surface, the connection surface at least partially including a conductive region to which a connection enlarged portion of the outer conductor is connected, the insertion hole having conductivity over an entire circumference of an inner surface, the corner having conductivity and being conducted with the inner surface of the insertion hole. In a state where the waveguide and the three-dimensional component are connected with each other, the connection enlarged portion is electrically conducted with the inner surface of the insertion hole through electrical connection with the connection surface and the corner, and smooth connection is made at the corner.
