Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices fail to provide a firm, resilient connection that is easily releasable, often requiring complex mechanisms or high forces to separate the connected parts.
Innovation Solution
A magnetic closure device with a first closure part and a second closure part, each equipped with a magnet device, where the locking element is designed to engage magnetically with the engagement section, allowing for a strong connection that can be easily released by adjusting the locking element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a magnetic closure device is used to create a firm connection, then the connection strength is improved, but the ease of separation deteriorates
Solution Approach 1:
The locking element is designed to be movable between a locked position (engaging with the engagement section) and an unlocked position. The magnetic force dynamically adjusts the locking strength based on the position of the locking element, allowing easy transition between firmly connected and easily separated states through simple user interaction with the adjustment part.
Solution Approach 2:
The patent replaces traditional mechanical locking mechanisms (such as springs, cam locks, or screw threads) with a magnetic field-based locking system. The magnetic attraction force provides the locking action, eliminating the need for complex mechanical components while maintaining strong connection strength and enabling easy separation through magnetic field modulation via the adjustment part.
2Ease of operation
If a complex mechanism is used to achieve easy separation, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the essential locking function from complex mechanical mechanisms and implements it through a simplified magnetic field-based system. By removing unnecessary mechanical components (springs, levers, threads) and retaining only the critical locking and releasing functions through magnetic interaction and a simple movable locking element, the device achieves easy separation without increasing complexity.
Solution Approach 2:
The magnetic locking system is self-actuating through the movement of the locking element along the closing direction. The magnetic attraction automatically engages the locking element with the engagement section when the closure parts are brought together, and the adjustment part allows simple user actuation to release the lock, eliminating the need for complex actuating mechanisms.
3Ease of operation
If a magnetic locking element is used, then the ease of operation is improved, but the reliability of the locked position deteriorates
Solution Approach 1:
The locking element is pre-positioned to engage with the engagement section through magnetic attraction when the closure parts are brought together along the closing direction. This preliminary magnetic engagement ensures that the locking element is already in the correct position and orientation before final locking occurs, maintaining reliability while allowing easy adjustment through the adjustment part.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The magnetic interaction provides a secure and resilient connection that can be effortlessly released, ensuring the closure parts are firmly connected yet easily separable with minimal effort.
Implementation Method 1
The first magnetic device and the second magnetic device interact in a magnetically attractive manner when the first closure part and the second closure part are placed against one another
Implementation Method 2
The at least one locking element is magnetically configured such that, in the closed position, the at least one locking element is biased by the first magnetic device and/or the second magnetic device toward engagement with the at least one engagement portion
