Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional threaded connector is used, then the connector can be securely attached to the interface port, but the ground connection may be lost when loosely coupled, introducing noise and performance degradation
Solution Approach 1:
The connector is divided into separate functional components: a non-conductive body for structural support, a conductive coupler for electrical connection, and a resilient grounding member for maintaining ground contact. This segmentation allows each component to optimize its specific function, ensuring reliable grounding independent of connection tightness.
Solution Approach 2:
A resilient grounding member acts as an intermediary element between the conductive coupler and the interface port. This mediator maintains continuous ground contact through elastic deformation, bridging the electrical connection even when the connector is loosely coupled, thereby preventing noise and performance degradation.
2Ease of operation
If a push-on connector design is used, then installation is simplified without rotation, but maintaining ground connection becomes difficult
Solution Approach 1:
The grounding member is designed with resilient properties that allow it to dynamically adapt to connection variations. Through elastic deformation, the grounding member automatically adjusts to maintain ground contact whether the connector is loosely or tightly coupled, ensuring reliable electrical connection without requiring rotational installation.
Solution Approach 2:
The resilient grounding member changes its physical state through elastic deformation in response to connection forces. This parameter change allows the grounding member to maintain optimal contact pressure with the interface port across varying connection tightness, ensuring consistent ground connection while preserving push-on installation simplicity.
3Productivity
If the connector is loosely coupled to allow easy installation, then installation speed increases, but ground contact is lost causing noise and packet errors
Solution Approach 1:
The resilient grounding member is pre-loaded with elastic force before installation. This preliminary stored energy enables the grounding member to immediately establish and maintain ground contact upon insertion, eliminating the need for tight coupling to ensure grounding, thereby allowing faster installation without compromising ground contact continuity.
Solution Approach 2:
The resilient grounding member provides beforehand cushioning through its elastic properties, compensating for potential ground contact loss due to loose coupling. This pre-positioned resilient element ensures continuous ground connection even when the connector is installed loosely, preventing noise and packet errors while maintaining high installation speed.
4Reliability
If threaded connection is used to ensure ground contact, then ground reliability improves, but device complexity increases due to rotation requirement
Solution Approach 1:
The connector structure is segmented into distinct functional elements: a non-conductive body, a conductive coupler, and a resilient grounding member. This segmentation simplifies the overall structure by eliminating the need for threaded mechanisms, while each component independently contributes to ground connection stability through its specialized function.
Solution Approach 2:
The traditional mechanical threaded connection system is replaced with a simplified push-on design featuring a resilient grounding member. This substitution eliminates complex threading mechanisms and rotational requirements, reducing device complexity while maintaining ground connection stability through the elastic properties of the grounding member.

AI summary
A coaxial cable connector includes a body configured to engage a coaxial cable having a conductive electrical grounding property, a post configured to engage the body and the coaxial cable when the connector is installed on the coaxial cable, and a non-threaded coupler coupled with the body and the post. The coupler is configured to engage an interface port at a retention force, and the non-threaded coupler houses a spring basket that bow radially inward relative to an internal surface of the threaded coupler so as to engage an interface port in order to provide an electrical ground connection between the interface port and the coupler.
