Magnetic Buckle Device for Bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buckle devices for bags and suitcases are inconvenient to use due to the need for precise alignment and significant force to insert and lock the zipper head, and after unlocking, the zipper head can move arbitrarily, making relocking difficult.
Innovation Solution
A magnetic buckle device with a buckle main body, first component, and second component that utilizes magnetic attraction to guide and secure the inserting head, allowing for easy engagement and disengagement with minimal user effort, and to prevent the inserting head from moving freely after disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional buckle device uses mechanical insertion without magnetic assistance, then the structure is simple, but the user must align the zipper head precisely and exert significant force to insert it
Solution Approach 1:
The patent replaces part of the mechanical insertion system with a magnetic field system. Magnetic components are embedded in the buckle device to generate magnetic attraction force that guides and pulls the zipper head into the insertion hole, eliminating the need for precise manual alignment and significant insertion force.
Solution Approach 2:
The patent introduces magnetic field as an intermediary between the zipper head and the buckle device. The magnetic components act as mediators that create an attractive force field, enabling the zipper head to be automatically guided and pulled into position without direct mechanical contact or user manipulation.
2Ease of operation
If conventional buckle device releases the zipper head completely after unlocking, then the buckle can be opened, but the zipper head moves arbitrarily and is difficult to relock
Solution Approach 1:
The patent uses magnetic attraction force to replace mechanical constraints for holding the zipper head in position. After unlocking, the magnetic components continue to exert attractive force on the zipper head, keeping it attached to the buckle device and preventing arbitrary movement, while still allowing controlled relocking.
3Ease of operation
If conventional buckle device requires manual alignment and force for insertion, then the locking mechanism is simple, but the operation requires two hands and is inconvenient when hands are occupied
Solution Approach 1:
The patent enables the buckle device to perform the alignment and insertion functions automatically through magnetic attraction. The magnetic components self-generate the guiding force and pulling action, eliminating the need for user hands to perform these functions, allowing operation even when hands are occupied.
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 buckle device simplifies the locking process by providing a guiding effect for the inserting head and maintaining the engaged state with magnetic force, reducing the need for manual alignment and force, and ensures the inserting head remains attached after unlocking, eliminating the need for manual repositioning during relocking.
Implementation Method 1
a magnetic attraction force is generated between the first component and the second component to assist in keeping the buckle main body in the engaged state
Implementation Method 2
the inserting head is attached onto the buckle main body by the magnetic attraction force between the first component and the second component

AI summary
A magnetic buckle device has a buckle main body and an inserting head. When the inserting head is close to an insertion hole of the buckle main body, the magnetic attraction force between a first component on the inserting head and a second component on the buckle main body can assist with inserting the inserting head into the insertion hole. After the inserting head is inserted to a predetermined position, the magnetic attraction force will keep the buckle main body in an engaged state even without any additional fixing means. When the buckle main body is switched to a disengaged state and the inserting head is moved out of the buckle main body, the magnetic attraction force attracts the inserting head to attach to the buckle main body, and thereby, after moved out, the inserting head cannot move arbitrarily.
