Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio frequency (RF) connectors have a complex and large-sized structure, making it difficult to meet design requirements for miniaturization and low-cost in communication modules.
Innovation Solution
A radio frequency (RF) connector with a cylindrical insulating portion, a cylindrical outer conducting portion, and a hollow inner conducting portion, where the insulating portion electrically separates the outer and inner conducting portions, and includes elastic conductive connectors and a card slot for secure electrical connections without the need for a middle connection rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional RF connector structure with separate first connector, second connector, and connection rod is used, then reliable electrical connection is achieved, but the device complexity and size increase
Solution Approach 1:
The patent combines the first connector, second connector, and connection rod into a single integrated RF connector structure. The insulating portion with integrated inner and outer conducting portions eliminates the need for separate connection rods and multiple connectors, reducing structural complexity while maintaining electrical connection reliability through the integrated design.
Solution Approach 2:
The patent employs a nested structure where the inner conducting portion is positioned within the insulating portion, which is in turn surrounded by the outer conducting portion. This nested arrangement allows multiple functional elements to be compactly integrated, reducing overall device complexity while preserving reliable electrical pathways.
2Reliability
If a traditional RF connector with separate connectors and connection rod is used, then electrical connection is established, but the volume and assembly spacing requirements increase
Solution Approach 1:
By merging the first connector, second connector, and connection rod into one integrated unit, the patent significantly reduces the overall volume of the connector assembly. The integrated structure eliminates gaps and redundant components, allowing compact placement on the filter and PCB without requiring excessive assembly spacing.
Solution Approach 2:
The nested arrangement of the inner conducting portion within the insulating portion, which is surrounded by the outer conducting portion, maximizes space utilization. This compact nested configuration reduces the volume occupied by the connector while maintaining all necessary electrical connection functions.
3Device complexity
If a simplified RF connector structure is used, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent segments the connector into distinct functional portions (insulating portion with inner conducting portion and outer conducting portion), each with clearly defined geometric features. This segmentation allows for standardized manufacturing processes and simplifies quality control, reducing the precision requirements compared to complex multi-component assemblies.
Solution Approach 2:
The patent employs cylindrical and circular geometric features throughout the connector structure. These curved, symmetrical shapes are easier to manufacture with standard machining processes and provide natural alignment features that reduce the need for high-precision assembly spacing, thereby lowering manufacturing precision requirements.

AI summary
A radio frequency (RF) connector includes an insulating portion configured in a cylindrical shape; an outer conducting portion configured in a cylindrical shape and disposed to surround an outer circumferential surface of the insulating portion; and an inner conducting portion disposed inside the insulating portion in a hollow shape and having both ends protruding from the insulating portion, the insulating portion electrically separating the outer conducting portion from the inner conducting portion.
