Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded connection mechanism is used in conventional RF connectors, then the connection provides mechanical strength and reliability, but the connection and disconnection process becomes time-consuming and reduces operational efficiency
Solution Approach 1:
The connector is divided into two functional parts: a push-on connection component for rapid engagement/disengagement and a threaded component for securing the connection. This segmentation allows the operator to quickly connect by pushing (solving the time loss issue) while the threaded portion provides the mechanical reliability when engaged.
Solution Approach 2:
The push-on connection mechanism performs the preliminary action of engaging the connector quickly before the threaded mechanism is fully tightened. This preliminary engagement ensures proper alignment and electrical contact are established rapidly, reducing connection time while maintaining reliability through the subsequent threading action.
2Strength
If a threaded fastening mechanism is used, then the connector maintains secure mechanical fastening, but the ease of operation deteriorates due to complex threading requirements
Solution Approach 1:
The fastening mechanism is segmented into a push-on portion for easy operation and a threaded portion for strength. The push-on action requires minimal effort and no rotational movement, dramatically improving ease of operation, while the threaded section engages to provide the necessary mechanical fastening strength.
Solution Approach 2:
Instead of requiring the user to initiate and complete a threading motion from scratch, the design inverts the approach by allowing push-on engagement first (the easier action), which then enables or facilitates the threading action. This reverses the traditional sequence where threading must be started first.
