Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connection portion for the electric component is disposed between the side surface portions of the outer conductor, then the electric component can be connected to the center conductor, but a short circuit may occur between the connection portion and the outer conductor
Solution Approach 1:
The patent introduces a dielectric member as an intermediary substance between the connection portion and the outer conductor. This dielectric member fills the space and provides electrical insulation, preventing short circuits while allowing the connection portion to be disposed between the side surface portions for easy component connection.
Solution Approach 2:
The outer conductor is divided into bottom surface portions and side surface portions, creating distinct functional zones. The connection portion is specifically disposed between the side surface portions, while the dielectric member is placed between the connection portion and the outer conductor to provide insulation. This segmentation allows both easy connection and short circuit prevention.
2Reliability
If the outer conductor has a crimping portion for crimping onto the shielded wire, then reliable electrical connection is achieved, but the structure becomes more complex
Solution Approach 1:
The crimping portion is integrated directly into the outer conductor as a unified structure, combining the connection function and the structural support function in a single component. This merging approach achieves reliable electrical connection through the crimping action while avoiding the need for separate fastening components, thus not increasing overall structural complexity.
