Flap Fixing Buckle with Embedded Magnets for Bag Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flap fixing buckles for bags are complex, prone to separation, costly to manufacture, and vulnerable to external damage, with exposed magnets that can be easily lost or damaged, and are difficult to adjust for varying bag volumes.
Innovation Solution
A simplified flap fixing buckle design featuring a plug member with a cross bar and a socket member with a coupling groove, where magnets are embedded for secure attachment and detachment without exposure, allowing for easy adjustment and reduced complexity in design and manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dual structure with strap and auxiliary strap is used for flap fastening, then the flap can be attached to the bag body, but the external appearance becomes complicated and aesthetic quality deteriorates
Solution Approach 1:
The patent merges the strap and auxiliary strap into a single integrated buckle structure. The buckle body incorporates both the strap attachment function and the bag body attachment function in one component, eliminating the need for separate auxiliary strap and reducing structural complexity while maintaining reliable flap fastening.
2Reliability
If multiple protruding straps and buckles are provided for flap fastening, then the flap can be securely attached, but the structure becomes prone to collision with external objects and separation
Solution Approach 1:
The patent embeds the magnet within the buckle body structure, creating a nested configuration where the magnetic element is protected inside the solid buckle component. This nesting protects the magnet from external collision while maintaining the magnetic attachment function, reducing vulnerability to harmful factors.
3Reliability
If multiple subsidiary elements are used in the flap fastening structure, then the flap can be fastened, but manufacturing costs increase and production process becomes complicated
Solution Approach 1:
The patent combines multiple functions into a single buckle component: the strap attachment function, the bag body attachment function, and the magnetic fastening function are all integrated into one piece. This merging reduces the number of subsidiary elements, simplifying the manufacturing process and reducing costs while maintaining reliable flap fastening capability.
4Ease of operation
If the magnet is exposed on the buckle for easy attachment and detachment, then the magnet can be easily accessed, but the magnet becomes vulnerable to external impact and loss
Solution Approach 1:
The patent nests the magnet inside the buckle body, creating a protected internal configuration. The magnet remains accessible for attachment and detachment operations while being shielded from external impact by the solid buckle structure, eliminating the risk of loss while maintaining ease of operation.
5Device complexity
If a fixed size flap structure is used, then the design is simple, but it cannot adapt to varying bag volumes and accommodation requirements
Solution Approach 1:
The patent incorporates an adjustable mechanism that allows the flap size to be dynamically changed. The buckle can be repositioned or reconfigured to accommodate different flap lengths and positions, enabling the same simple structure to adapt to varying bag volumes and accommodation requirements without increasing overall structural complexity.
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 design provides a stable, aesthetically pleasing, and cost-effective solution that prevents magnet damage and separation, while allowing for easy operation and adjustment to fit various bag volumes.
Implementation Method 1
a first magnet is embedded in the coupling protruding portion and a second magnet is embedded in the coupling groove of the socket member, so that the plug member and the socket member are coupled to each other by magnetic force

AI summary
The present disclosure relates to a flap fixing buckle including: a plug member having a cross bar that transverses an intermediate portion of a loop-shaped frame, in which a coupling protruding portion in which a magnet is embedded protrudes from the cross bar; and a socket member having a coupling groove into which the coupling protruding portion is inserted and which is formed in an upper surface of the socket member, in which a magnet is embedded inside the coupling groove, and a wing portion extends at the periphery of the upper surface of the socket member, and as a result, when the flap fixing buckle is installed on a bag or the like, an aesthetic external appearance may be formed because of a simple configuration, and the flap fixing buckle may be stably and conveniently fastened.
