Movable Contact Plug Connector for Selective Function Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors do not allow selective activation of certain functions of electronic devices after mating, leading to unnecessary power or signal transmission when not required.
Innovation Solution
A plug electrical connector with a movable member that moves between contact and retreat positions, allowing contact terminals to engage or disengage with detecting terminals in a receptacle connector, thereby activating or deactivating functions as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical connectors are mated to transmit electrical power or signals, then electrical connection is established, but certain functions cannot be selectively activated
Solution Approach 1:
The patent applies the dynamics principle by introducing a movable member that can shift between a first position (where contact terminals engage detecting terminals to activate functions) and a second position (where contact terminals disengage from detecting terminals to deactivate functions). This dynamic mechanism allows the connector to selectively activate functions based on user need, resolving the contradiction between adaptability and device complexity.
2Reliability
If contact terminals continuously contact detecting terminals, then functions remain activated, but unnecessary power or signal transmission occurs
Solution Approach 1:
The patent applies periodic action by enabling the movable member to periodically engage and disengage contact terminals with detecting terminals based on operational requirements. This allows functions to be activated only when needed rather than continuously, reducing unnecessary power transmission while maintaining reliable function activation control when required.
3Reliability
If all terminals remain connected after mating, then electrical connection is maintained, but insertion loss, return loss, common mode noise, and crosstalk increase
Solution Approach 1:
The patent applies segmentation by dividing the electrical connection into two independent parts: plug terminals that remain continuously connected to receptacle terminals for maintaining stable electrical connection, and contact terminals that are selectively connected to detecting terminals through the movable member. This segmentation allows the plug terminals to maintain reliable connection while contact terminals can be disconnected to reduce insertion loss, return loss, common mode noise, and crosstalk when functions are not needed.
