Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial RF connectors face challenges in accurate testing due to the influence of circuit boards, requiring welding and resulting in inaccurate test results and non-reusable connectors, which increases costs.
Innovation Solution
A connector adapter system comprising two sub-adapters that directly and electrically connect the coaxial RF connector to coaxial RF cables, allowing for independent connection to test equipment without circuit boards, enabling accurate testing and reusability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the coaxial RF connector is connected to test equipment through circuit boards and cable connectors, then electrical connection is established, but the circuit board impact causes inaccurate test results
Solution Approach 1:
The patent extracts and removes the circuit board from the test connection path by introducing a dedicated adapter that directly connects the coaxial RF connector to the cable connector. This extraction eliminates the harmful influence of the circuit board on test measurements while maintaining the necessary electrical connection.
Solution Approach 2:
The patent introduces an adapter as an intermediary component between the coaxial RF connector and the cable connector. This adapter serves as a dedicated test interface that mediates the connection, allowing direct measurement without the circuit board's interference while maintaining electrical continuity.
2Ease of manufacture
If the coaxial RF connector is welded to circuit boards for testing, then electrical connection is established, but the connector cannot be removed and reused, increasing costs
Solution Approach 1:
The patent segments the test connection system into separate, independent components: the coaxial RF connector, the adapter, and the cable connector. This segmentation allows the connector to be detached from the test setup and reused, eliminating the need for permanent welding while maintaining testing simplicity.
Solution Approach 2:
The patent transitions from a static, permanent welding connection to a dynamic, detachable connection system. The adapter provides a reusable interface that can be connected and disconnected multiple times, enabling the connector to be reused across different testing operations without permanent attachment.
3Productivity
If the coaxial RF connector is permanently connected to circuit boards, then testing can be performed, but the connector cannot be reused, increasing costs
Solution Approach 1:
The patent enables recovery and reuse of the coaxial RF connector by introducing a detachable adapter interface. Instead of permanently discarding the connector after one-time welding to a circuit board, the adapter allows the connector to be disconnected, recovered, and reused for multiple testing operations.

AI summary
A connector adapter includes a first sub-adapter directly and electrically connected with a first end of a connector and a second sub-adapter directly and electrically connected with a second end of the connector. The first end of the connector is electrically connected to a first cable through the first sub-adapter and to a test equipment through the first cable. The second end of the connector is electrically connected to a second cable through the second sub-adapter and to the test equipment through the second cable.
