Magnetic Coupling Lock to Prevent Unintended Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for connecting and disconnecting two parts often face issues with unintended disconnection due to relative movement, lacking a secure locking mechanism that prevents decoupling during intended motion.
Innovation Solution
A mechanism comprising a first and second magnetic component with a third movable component, where a fourth component engages to prevent unintended disconnection by aligning magnetic dipoles and using a mechanical lock with latches and guides to secure the assembly, allowing controlled rotation and alignment for locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnetic connection mechanism is used to connect two parts, then connection and disconnection can be achieved through magnetic interaction, but unintended disconnection may occur due to relative movement between components
Solution Approach 1:
The fourth component acts as a mechanical intermediary/locking element between the magnetic components. It provides a positive mechanical lock that prevents unintended disconnection while allowing the magnetic field to maintain the connection. The fourth component mediates between the magnetic attraction force and the requirement for stable positioning, translating the magnetic interaction into a secure locked state.
2Adaptability or versatility
If the third component is made movable relative to the first component to enable switching between connection and disconnection, then operational flexibility is improved, but control over the connection state becomes more difficult
Solution Approach 1:
The mechanism employs dynamic elements (movable third component, engageable fourth component) that can transition between different states. The third component can move to engage or disengage the fourth component, providing controlled switching between locked and unlocked states. This dynamic design allows the system to adapt between connection and disconnection while maintaining precise control through defined engagement positions.
3Reliability
If a mechanical lock is added to prevent unintended disconnection, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The fourth component serving as a mechanical lock is integrated with the existing magnetic connection mechanism. Rather than adding a completely separate locking system, the design merges the locking function into the existing component structure, where the fourth component works in conjunction with the magnetic parts to provide both magnetic attraction and mechanical locking in a unified assembly.

AI summary
A mechanism comprising a first component (24) having a first magnetic part, a second component (23), and a third component (25) having a second magnetic part, the third component (25) being moveable relative to said first component (24) in a given direction to effect connection and or disconnection of the first and second components by causing interaction of the first and second magnetic parts, wherein, when connected, the first and second components are able to move relative to one another in said given direction. The mechanism further comprising a fourth component (26) for engagement with said first component (24) to prevent movement of the third component (25) relative to the first component (24) as a result of relative movement of the first and second components, thereby to prevent unintended disconnection of the first and second components.
