Solution Overview
Problem
Existing HF coaxial connection systems require tools for secure torque application and lack integrated solutions for centering and twist protection, making them cumbersome and prone to improper connections.
Innovation Solution
An HF coaxial connection element with an integrated torque limiter, centering element, and twist protection element, featuring a guiding element with radially arranged indentations and spring-preloaded pressing elements, allows for secure, tool-free connections with a predetermined torque, ensuring correct positioning and preventing twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional coaxial connectors are used with external torque tools, then secure torque application is achieved, but device complexity and ease of operation deteriorate due to requiring additional tools
Solution Approach 1:
The patent combines the torque limiter, centering element, and twist protection element into a single integrated connector component. This merging eliminates the need for separate external tools while maintaining secure torque application, directly resolving the contradiction between connection reliability and device complexity
Solution Approach 2:
The integrated connector performs multiple functions simultaneously: torque limitation, centering, twist protection, and connection securing. This multi-functionality replaces what previously required multiple separate tools, improving ease of operation while maintaining reliability
2Ease of operation
If traditional coaxial connectors without integrated centering are used, then connection is possible, but manufacturing precision deteriorates due to misalignment
Solution Approach 1:
The centering element performs preliminary alignment of the connector components before the final tightening action. This pre-centering ensures precise alignment is achieved automatically during the connection process, eliminating misalignment issues while maintaining ease of operation
3Device complexity
If connectors without twist protection are used, then connection is simpler, but reliability deteriorates due to twisting motion
Solution Approach 1:
The twist protection element is merged with the torque limiter and centering element into a single integrated component. This combination provides twist protection without significantly increasing overall device complexity, as all three protective functions are achieved through one unified structure
Solution Approach 2:
The twist protection element utilizes asymmetric geometric features (such as keyhole shapes or shaped protrusions) that physically prevent twisting motion. This asymmetric design effectively blocks rotational misalignment while maintaining a relatively simple overall connector structure
