Magnetic Fastener Pocket Structure Against Lateral Disengagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic fasteners face issues with inadvertent disengagement due to weak lateral magnetic attraction, making them difficult to use in applications like horse halters or pet collars, where unpredictable animal behavior and large surface areas complicate coupling and uncoupling.
Innovation Solution
A magnetic fastener design featuring a male and female component with complementary magnets, where the female component includes a hooded portion and peripheral wall forming a pocket to securely receive the male component, preventing disengagement in both lateral and perpendicular directions through magnetic attraction and mechanical coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic fasteners are used to enable easy coupling and uncoupling, then ease of operation is improved, but reliability deteriorates due to weak lateral magnetic attraction causing inadvertent disengagement
Solution Approach 1:
The patent combines magnetic attraction with mechanical interlocking features (protrusions and recesses) into a unified fastening system. The magnetic components provide automatic alignment and holding force, while the mechanical features prevent lateral disengagement, creating a hybrid fastening mechanism that achieves both ease of operation and reliability.
Solution Approach 2:
The patent introduces mechanical protrusions and recesses as intermediary elements between the magnetic components. These intermediaries bridge the gap between magnetic attraction and mechanical retention, providing additional lateral stability without compromising the ease of magnetic coupling.
2Reliability
If frictional coupling surfaces are added to prevent lateral movement, then reliability is improved, but ease of operation deteriorates due to increased difficulty in coupling
Solution Approach 1:
The patent replaces friction-based mechanical coupling with magnetic attraction for the primary coupling action. The magnetic field provides the necessary holding force without requiring high friction surfaces, allowing components to couple easily through magnetic pull-in while still preventing lateral disengagement through geometric interlocking.
3Reliability
If protrusions are added to the housing to prevent lateral movement, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies magnetic properties locally at specific coupling points rather than throughout the entire housing structure. This localized approach provides the necessary lateral stability through targeted magnetic attraction zones without requiring complex structural modifications to the entire housing, maintaining simplicity while achieving reliability.

AI summary
A magnetic fastener includes a female component and a male component. The female component includes a base, a hooded portion spaced from the base and formed opposite thereto, and a peripheral wall connecting the base to the hooded portion. A pocket is formed between the base and the hooded portion. The hooded portion includes a slot formed therein. A portion of the female component is magnetically attractive. The male component includes an insertion portion and a shaft extending from the insertion portion. A portion of the male component is formed by a magnet. The male component is configured to be coupled to the female component when the magnet is magnetically coupled to the portion of the female component that is magnetically attractive, the insertion portion is received within the pocket, and the shaft is received within the slot.
