Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current buckle devices require precise alignment and force to insert the zipper puller, making it difficult to lock luggage, especially when one hand is occupied.
Innovation Solution
A magnetic buckle device with a first and second base, and components that utilize magnetic attraction and repulsion forces to facilitate easy insertion and release of the inserting component, reducing the need for manual force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional buckle device is used, then the zipper can be locked securely, but the user must precisely align and apply force to insert the zipper puller, which is inconvenient especially when one hand is occupied
Solution Approach 1:
The patent replaces the traditional mechanical alignment and insertion system with a magnetic field-based system. The magnetic attraction force automatically guides the zipper puller into the buckle device without requiring precise manual alignment, thereby improving ease of operation while reducing the complexity of user interaction with the device
Solution Approach 2:
The magnetic buckle device performs the alignment function automatically through magnetic attraction. The zipper puller is naturally drawn into the correct position by the magnetic force between the magnet in the buckle and the ferromagnetic material in the puller, eliminating the need for user intervention in the alignment process
2Ease of operation
If a traditional buckle device is used, then the locking function is achieved, but significant user force is required to insert the zipper puller into the buckle
Solution Approach 1:
The patent substitutes the mechanical force-based insertion mechanism with a magnetic field-based attraction mechanism. The magnetic force continuously pulls the zipper puller toward the buckle device during the insertion process, significantly reducing the manual force required compared to traditional mechanical buckles that rely solely on user-applied insertion force
Solution Approach 2:
The magnetic field acts as an intermediary force between the user and the buckle device. Instead of directly applying mechanical force to overcome resistance, the user indirectly utilizes the magnetic attraction field to guide and pull the zipper puller into the buckle, reducing the effort required

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 insertion and release process by using magnetic forces to guide and maintain the buckled state, enhancing user convenience.
Implementation Method 1
a magnetic attraction force is generated between the first component and the second component, thereby maintaining the inserting component in the buckled state

AI summary
A magnetic buckle device has a first base (10), an inserting component (30) and a second base (20). The inserting component (30) can be inserted into the first base (10), which engages the inserting component (30). The first base (10) and the second base (20) can move or rotate with respect to each other, thereby converting the inserting component (30) into the unbuckled state. When the inserting component (30) is close to an inserting component (11) of the first base (10), a magnetic attraction force is generated for drawing the inserting component (30) to the inserting component receiver (11) of the first base (10). When the inserting component (30) is inserted completely, the magnetic attraction force auxiliary keeps the inserting component (30) in the buckled state, so any additional buckling structure is not necessary.
