Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple differently sized connectors and clamping tools are manufactured to match different coaxial cable specifications, then compatibility with various cable types is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent applies universality by designing a single standardized connector body that can accommodate multiple coaxial cable specifications (RG6, RG7, RG11, RG59, etc.) through a unified interface design. This eliminates the need for multiple differently sized connectors and clamping tools, reducing device complexity while maintaining compatibility across various cable types.
Solution Approach 2:
The patent implements the nesting principle by placing the coaxial cable connector inside a universal adapter housing. The connector and cable assembly are nested within the adapter, which provides the standardized interface. This nested structure allows a single adapter to accommodate different cable specifications without requiring multiple external tools or connectors.
2Reliability
If multiple differently sized hexagonal clamping tools are prepared to ensure sufficient compression force on connectors for different cable specifications, then connection reliability is improved, but portability and ease of operation deteriorate
Solution Approach 1:
The patent applies universality by designing a single hexagonal clamping tool with an adjustable mechanism that can provide sufficient compression force for connectors of different cable specifications. This eliminates the need to carry multiple differently sized clamping tools, improving portability and ease of operation while maintaining connection reliability across various cable types.
3Reliability
If connectors are designed for specific cable specifications, then manufacturing precision and connection reliability are improved, but adaptability to different cable types deteriorates
Solution Approach 1:
The patent introduces a universal adapter as an intermediary component between the standardized connector and various coaxial cable specifications. The adapter serves as a mediator that maintains the standardized connector design for reliable signal transmission while accommodating different cable types through its adaptable interface, thus resolving the contradiction between reliability and adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a stable and firm connection for coaxial cables of different specifications, eliminating the need for multiple clamping tools and ensuring reliable signal transmission across various cable types.
Implementation Method 1
a contact spring mounted in the first tubular end portion; a conducting element located outside and around the contact spring
Implementation Method 2
the elastic hooking portions on the mini adapter are radially compressed by the inner sleeve of the standard adapter to thereby force the finger clamp to mechanically and electrically contact with the central conductor

AI summary
A coaxial cable connector includes a standard and a mini adapter. The standard adapter includes coaxial hollow inner and outer sleeves. The mini adapter includes an inner member having a finger clamp; and a cylindrical housing having a first and a second tubular end portion. The first tubular end portion is externally formed of elastic hooking portions corresponding to the finger clamp in the mini adapter, and a plurality of long slots behind the elastic hooking portion. A contact spring is provided in the mini adapter with contact strips thereof received in the long slots. When the mini adapter is fully inserted into the standard adapter, the inner sleeve compresses the elastic hooking portions to thereby force the finger clamp to engage with a central conductor of the coaxial cable, and pushes the contact strips to mechanically and electrically engage with a foil layer of the coaxial cable.
