Magnetically-Attracted Buckle With Segmented Containing Hole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetically-attracted buckle designs for wearable devices are cumbersome and inconvenient to handle with one hand due to the magnetic attraction causing the back-pressing baffle to flip over and not pass through the containing hole properly.
Innovation Solution
A magnetically-attracted buckle design featuring a first buckle with a buckle seat and a second buckle with a raised magnetically-attracted member, where the second member attracts the first member through a hollow, allowing one-handed buckling and jamming to prevent easy removal, along with expandable buttons and jamming parts for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetically-attracted buckle uses magnetic attraction to connect two belts, then the connection is secure and automatic, but the back-pressing baffle flips over and fails to pass through the containing hole properly, making it cumbersome to handle with one hand
Solution Approach 1:
The buckle is divided into separate functional components: a containing hole structure, a back-pressing baffle, and a limiting groove. The containing hole is segmented into different sections with the limiting groove creating a distinct barrier. This segmentation allows the baffle to be guided through specific paths, preventing it from flipping over while maintaining the magnetic connection security.
Solution Approach 2:
The limiting groove acts as an intermediary structure between the containing hole and the back-pressing baffle. It mediates the interaction by providing a physical constraint that guides the baffle's movement, ensuring it passes through the containing hole correctly without being affected by the magnetic attraction force that would otherwise cause it to flip.
2Reliability
If the back-pressing baffle is attracted by the magnet to fix the connection, then the buckle is secure, but the baffle flips over before passing through the containing hole, making handling more inconvenient
Solution Approach 1:
The limiting groove is pre-configured in the containing hole structure to guide the back-pressing baffle's movement before magnetic attraction takes effect. This preliminary structural arrangement ensures that the baffle follows the correct path through the containing hole, preventing flipping over during the buckling process and reducing handling complexity.
Solution Approach 2:
The limiting groove structure enables the back-pressing baffle to self-guide through the containing hole without external intervention. The geometric constraint of the limiting groove automatically directs the baffle's movement, allowing the system to correct its own potential flipping issue through passive structural design rather than active control.
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
Enables easy one-handed connection and secure attachment of the buckle, preventing accidental removal and improving handling convenience while maintaining magnetic attraction for secure engagement.
Implementation Method 1
the second magnetically-attracted member attracts the first magnetically-attracted member, passing through the hollow
Implementation Method 2
the second magnetically-attracted member is jammed in the hollow, so it can avoid the second buckle from being easily pulled out
