Solution Overview
Problem
Existing closure devices fail to provide a firm, resilient connection that can be easily and conveniently released, often requiring complex mechanisms or high forces to separate the connected parts.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a magnetic closure device uses magnetic interaction for locking, then the connection becomes firm and resilient, but the device complexity increases due to the need for additional magnetic devices and adjustment mechanisms
Solution Approach 1:
The patent combines multiple functions into the locking element: it serves as both the magnetic interaction component (through ferromagnetic material) and the mechanical locking component (through engagement with the engagement section). This merging reduces the need for separate magnetic devices while maintaining firm connection.
Solution Approach 2:
The locking element is designed to perform multiple functions: it provides magnetic attraction to assist closing, mechanical locking through engagement with the engagement section, and controlled release through rotation. This multi-functionality reduces overall device complexity by eliminating the need for separate mechanisms for each function.
2Strength
If a closure device uses a complex locking mechanism to achieve firm connection, then the connection strength improves, but the ease of operation deteriorates due to difficulty in releasing the connection
Solution Approach 1:
The locking element is designed to be rotatable about an axis, transforming the static locking mechanism into a dynamic one. This allows the locking element to easily transition from the locked position (engaged with engagement section) to the released position (rotated out of engagement) by simply rotating around the axis, significantly improving ease of operation.
Solution Approach 2:
Instead of requiring force to push the locking element out of engagement, the mechanism inverts the release action: rotating the locking element about its axis automatically disengages it from the engagement section. This inversion of the release mechanism makes operation much easier and more convenient.
3Ease of operation
If a closure device uses magnetic interaction for assisted closing, then the ease of operation improves, but the device complexity increases due to additional magnetic components
Solution Approach 1:
The patent integrates magnetic functionality directly into the locking element by incorporating ferromagnetic material, rather than using separate magnetic devices. This merging provides magnetic assistance for closing while minimizing additional components and device complexity.
Solution Approach 2:
The ferromagnetic material is applied locally to specific regions of the locking element where magnetic interaction is needed, rather than making the entire component magnetic. This localized application provides the necessary magnetic assistance for closing while keeping the overall device complexity low.

AI summary
A locking device (1, 1A-1D) comprises a first locking part (2, 2A-2D) having a body (20) and a second locking part (3, 3A-3D). A locking element (23) and an engagement section (310) engage with each other in a closed position such that the first locking part (2, 2A-2D) and the second locking part (3, 3A-3D) are locked together. The first locking part (2, 2A-2D) has a first magnetic element (22) and the second locking part (3, 3A-3D) has a second magnetic element (32), which attract each other magnetically when the first locking part (2, 2A-2D) and the second locking part (3, 3A-3D) are brought into contact.The at least one locking element (23) is magnetically designed such that the at least one locking element (23) in the closed position is biased by the first magnetic device (22) and/or the second magnetic device (32) in the direction of engagement with the at least one engagement section (310), wherein the first locking part (2, 2A-2D) has an adjusting part (21) which can be actuated by rotating an actuating element (24) in an actuating direction (B) in order to disengage the at least one locking element (23) from each other and from the at least one engagement section (310) in order to release the first locking part (2, 2A-2D) and the second locking part (3, 3A-3D).
