Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welding is used to connect center conductors of coaxial cables, then electrical connection is achieved, but connection errors frequently occur and the process is complicated and time-consuming
Solution Approach 1:
The patent replaces the welding process (thermal/chemical system) with a mechanical compression system. The fixing element with inward-bent wings applies mechanical force to compress the connecting terminal against the center conductor, achieving reliable electrical connection without welding. This substitution eliminates the complexity and error-prone nature of welding while maintaining connection reliability.
Solution Approach 2:
The patent introduces a connecting terminal as an intermediary component between the center conductor and the fixing element. This terminal serves as a mediator that receives mechanical compression from the fixing element and establishes electrical contact with the center conductor, simplifying the overall connection process and improving reliability by separating the mechanical and electrical functions.
2Reliability
If welding process is used to connect coaxial cables, then electrical connection is established, but the process is time-consuming and causes serious loss upon failure
Solution Approach 1:
The patent replaces the time-consuming welding process with a quick mechanical compression operation. The fixing element can be rapidly installed by bending its wings inward to compress the connecting terminal, eliminating the lengthy welding procedure while maintaining stable electrical connection. This significantly reduces connection time and minimizes losses from connection failures.
3Ease of operation
If simple connection method is used for coaxial cables, then installation is easier, but connection may loosen over time
Solution Approach 1:
The patent employs a dynamic fixing mechanism where the wings of the fixing element can be bent inward to apply compression force. This dynamic adjustment allows the connection to be easily installed by simply bending the wings, while the continuous compression force prevents loosening over time, maintaining both ease of operation and connection stability.
Solution Approach 2:
The fixing element is pre-designed with inward-bent wings that are prepared in advance to apply compression force. This preliminary configuration ensures that when the connecting terminal is installed, the compression force is immediately applied, preventing any potential loosening from the outset while keeping the installation process simple and easy.
