Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic buckle assemblies either facilitate quick mating or separation but not both, as the magnetic forces interfere with each other, leading to inefficient operations.
Innovation Solution
A magnetic buckle assembly that includes a first buckle component, a second buckle component, a switch, an operating component, a first magnetic component, a second magnetic component, and a latch, where the operating component drives the switch to change the direction of the magnetic force of the second magnetic component, allowing for both magnetic attraction and repulsion to facilitate mating and separation operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If two magnetic components are installed on the male buckle and female buckle to generate magnetic attracting force, then the mating process is accelerated, but the separating process is interfered with
Solution Approach 1:
The patent applies the dynamics principle by making the magnetic component's polarity switchable between north and south. The polarity of the magnetic component can be dynamically changed through a switching mechanism (such as a solenoid or Hall effect sensor) that responds to the operational state of the buckle. During mating, the magnetic component generates attractive force; during separation, the polarity is switched to generate repulsive force, thus resolving the contradiction between fast mating and easy separation.
Solution Approach 2:
The patent applies the parameter changes principle by changing the magnetic polarity parameter of the magnetic component. Instead of using fixed polarity magnets, the system uses controllable magnetic components (electromagnets or magnets with switchable orientation) that can change their magnetic field direction. This parameter change allows the same magnetic component to provide both attraction for mating and repulsion for separation, eliminating the need for separate magnetic components for each function.
2Ease of operation
If two magnetic components are installed on the male buckle and female buckle to generate magnetic repelling force, then the separating process is accelerated, but the mating process is interfered with
Solution Approach 1:
The system dynamically adjusts the magnetic interaction based on the operational phase. During separation, the magnetic component is configured to generate repulsive force to assist user action; during mating, the configuration is changed to generate attractive force. This dynamic adaptation resolves the contradiction by having the magnetic component serve different functions at different times rather than being fixed in one mode.
Solution Approach 2:
The magnetic polarity parameter is changed based on operational requirements. The system uses controllable magnetic components that can switch between generating attractive and repulsive forces. This parameter switching allows the magnetic component to provide repulsion during separation (improving ease of operation) and attraction during mating (improving speed), thus resolving the contradiction.
3Device complexity
If conventional buckle assembly is used, then the structure is simple, but the mating and separation processes are slow
Solution Approach 1:
The patent applies mechanics substitution by replacing part of the purely mechanical mating/separation mechanism with a magnetic field-based system. Instead of relying solely on manual alignment and insertion forces, the system uses controllable magnetic attraction to assist and accelerate the mating process. Similarly, magnetic repulsion assists the separation process, reducing the manual force required and increasing operational speed while maintaining relatively simple overall structure.

AI summary
A magnetic buckle assembly includes first buckle component, a second buckle component for mating with the first buckle component, a switch movably disposed on the second buckle component, an operating component slidably disposed on the second buckle component and for driving the switch to move. The first magnetic component, a first magnetic component disposed on the first buckle component, a second magnetic component disposed on the switch and for magnetically attracting or repelling the first magnetic component, and a latch movably disposed on the second buckle component and for engaging with the first buckle component. The latch moves along with sliding movement of the operating component. The operating component drives the switch to move to change a direction of a magnetic force of the second magnetic component acting on the first magnetic component when the operating component is operated to slide to disengage the latch from the first buckle component.
