Rotary Connector Locking Groove to Prevent False Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing connectors, incorrect rotational start positions can lead to engagement of the plug and socket without a proper lock mechanism, causing users to erroneously believe a connection is complete when it is not.
Innovation Solution
A connector design featuring a rotatable plug and socket with a claw portion and connection groove system, where the socket is configured to restrict movement and rotation in specific positions, preventing incorrect engagement and ensuring a secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the plug and socket are connected without a proper lock mechanism, then the connection can be made quickly, but the user may erroneously recognize the connection as complete when it is not properly engaged
Solution Approach 1:
The connector provides tactile feedback through the engagement of the claw portion with the connection groove portion, and visual feedback through the alignment of the first and second connection members. The lock mechanism provides a distinct engagement sensation that confirms proper connection, preventing erroneous recognition of incomplete connections as complete.
Solution Approach 2:
The connector performs self-verification through its mechanical design. The claw portion automatically engages with the connection groove portion when properly aligned, and the lock mechanism self-activates to prevent disconnection. The design inherently prevents erroneous recognition without requiring external verification systems.
2Ease of operation
If the socket is made rotatable to allow proper engagement, then the connection can be securely established, but incorrect rotational positions can lead to improper engagement
Solution Approach 1:
The connection groove portion is designed with an asymmetric shape that only matches the claw portion at the correct rotational position. The groove extends in a specific direction and has unique geometric features that prevent engagement at incorrect angles, ensuring that the plug and socket can only be properly connected when rotated to the precise correct orientation.
Solution Approach 2:
The design incorporates preliminary alignment features that guide the plug and socket into the correct rotational position before final engagement. The first and second connection members have pre-aligned geometric features that naturally orient the components correctly as they approach each other, reducing the risk of incorrect engagement before the locking action occurs.
3Adaptability or versatility
If the connection groove portion allows movement in multiple directions, then the connector is more flexible, but the connection integrity may be compromised
Solution Approach 1:
The connection groove portion is designed to be dynamic during the connection process, allowing the claw portion to move along the groove's path as the plug is inserted and rotated. The groove provides guided movement in multiple directions (axial insertion, rotational engagement) while maintaining control. Once engaged, the system transitions to a stable locked state where the claw portion is securely held by the groove's geometry, preventing unintended disengagement while maintaining connection integrity.

AI summary
A connector includes a plug including a first connection member and a socket including a second connection member. The first connection member includes a first body portion and a claw portion. The second connection member includes a second body portion and a connection groove portion. The connection groove portion includes a first groove portion configured to guide movement of the claw portion in the first direction in a state where the second connection member is located at the first position and a second groove portion configured to restrict movement of the claw portion in the first direction and in a direction approaching the plug in a state where the second connection member is located at the second position. The second body portion includes a restricting portion configured to accommodate the claw portion and to restrict rotation of the socket with respect to the plug in the circumferential direction.
