Lever-Controllable Magnetic Buckle for Multi-Directional Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic buckles allow only one-way separation of the male member from the female member, making it difficult to use them in applications like clothing and backpacks where the correct orientation is required for easy separation.
Innovation Solution
A lever-controllable magnetic buckle design with a male member and a female member featuring a guide section with multiple guide surfaces, allowing the male member to be selectively separated from the female member in different directions through a pivotally connected control lever.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional magnetic buckle uses a single-direction separation mechanism, then the structure is simple, but the ease of operation deteriorates because the user must correctly determine the relative position of the buckle to separate it
Solution Approach 1:
The patent transitions from single-direction separation to multi-directional separation capability. The male member is designed with guide surfaces that allow separation in multiple directions (first direction and second direction), enabling users to separate the buckle regardless of its orientation on the object. This dimensional change in separation capability directly improves ease of operation.
Solution Approach 2:
The male member serves multiple functions: it can be separated in at least two different directions while maintaining a single magnetic engagement structure. The guide surfaces are configured to accommodate separation forces from different directions, making the buckle universally operable regardless of how it is positioned on the object.
2Adaptability or versatility
If the male member allows separation in multiple directions, then the adaptability improves for different orientations, but the device complexity increases due to additional guide surfaces and structural features
Solution Approach 1:
The guide surfaces on the male member are configured to receive separation forces from multiple directions. The first guide surface and second guide surface are positioned at different orientations, allowing the male member to be separated in corresponding different directions while maintaining structural integrity.
Solution Approach 2:
The guide surfaces are asymmetrically positioned on the male member to accommodate multi-directional separation needs. This asymmetric configuration allows the buckle to adapt to different orientations on objects while maintaining a unified magnetic engagement structure, achieving versatility without excessive complexity.

Implementation Method 1
a male-side magnetic element (102) mounted in the male member (10)... a female-side magnetic element (112) mounted in the female member (11) for magnetically attracting the male-side magnetic element (102) thereto

AI summary
A lever-controllable magnetic buckle includes a male member having a male engaging section, a female member having a female engaging section formed with two groups of female guide-out surface, and a control lever. The male member is magnetically attracted for moving to the female member with the male engaging section retained to the female engaging section. The control lever is pivotally connected to the male member and has an actuating cam contacting with the female member. The female member will contact with surfaces of the actuating cam at different positions thereof when the control lever is pivotally swung relative to the male member, allowing the male engaging section to disengage from the female engaging section. Then, the control lever can be further swung to move the male member in different directions to selectively contact with one of the two groups of female guide-out surface and be completely separated from the female member.
