Magnetic RF Connector Shielding for Tunable Coupling Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
RF connectors with shielding structures face challenges in providing a coupling force that meets the specific needs of various communication equipment while allowing for easy attachment and detachment, especially in environments where quick replacement is necessary, such as in military situations or during home automation where signal interference and cost-effective maintenance are concerns.
Innovation Solution
The RF connector employs a magnetic attachment system using magnets of opposite polarities to facilitate easy attachment and detachment, with the option to adjust the number and arrangement of magnets and the shielding structure to achieve the desired coupling force based on the type and use of the communication equipment, and incorporates a shielding structure to enhance signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnets are used for attachment and detachment, then ease of operation is improved, but coupling force may be insufficient for certain applications
Solution Approach 1:
The patent applies parameter changes by allowing the number of magnets to be adjusted according to different application requirements. The connector can be configured with varying numbers of magnets (e.g., 1, 2, or more) to achieve the desired coupling force while maintaining easy magnetic attachment and detachment functionality.
2Object-affected harmful factors
If shielding structure is added, then signal interference is reduced, but device complexity increases
Solution Approach 1:
The patent applies local quality by providing shielding structures at specific locations where signal interference is most critical, rather than enclosing the entire connector. The shielding is strategically placed to protect the connection portion and signal paths while maintaining overall structural simplicity and avoiding unnecessary complexity.
3Object-affected harmful factors
If shielding structure is added, then shielding function is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies merging by integrating the shielding structure with existing connector components such as the housing or connection portions. The shielding is combined with structural elements that already exist in the connector design, thereby providing electromagnetic shielding functionality without requiring separate manufacturing processes or additional complex assembly steps.
4Ease of operation
If magnets are used for attachment, then ease of operation is improved, but shielding function may be compromised
Solution Approach 1:
The patent applies the intermediary principle by introducing shielding structures as mediator elements between the magnets and the external environment. The shielding acts as an intermediate layer that allows the magnetic attachment function to operate effectively while simultaneously blocking electromagnetic interference from affecting the connection portion and signal paths.
