Solution Overview

Problem

Conventional magnetic buckle assemblies either facilitate quick mating or separation but not both, due to interference from magnetic attracting or repelling forces, which complicates the operation of child carrier harness systems.

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, and a second magnetic component, where the operating component drives the switch to change the direction of the magnetic force, allowing the first magnetic component and second magnetic component to magnetically attract or repel each other for both mating and separation operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If magnetic attracting force is used to accelerate mating process, then mating speed is improved, but separation process is interfered with

Engineering Contradiction:
Improvemating speedVSAvoidseparation operation
Core Design Contradiction:
SpeedVSEase of operation

Solution Approach 1:

The magnetic component's polarity is made changeable through a switching mechanism. When the latch is engaged, the magnetic component exhibits attracting polarity to accelerate mating. When the latch is disengaged, the magnetic component switches to repelling polarity to facilitate separation. This dynamic property allows the same magnetic component to serve dual functions of acceleration and release.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The magnetic force parameter is changed from constant to variable by introducing a switching mechanism. The switching mechanism alters the magnetic polarity based on the operational state (engaged/disengaged), thereby changing the magnetic force from attracting to repelling. This parameter change enables the magnetic buckle to overcome the contradiction between fast mating and easy separation.

Inventive Principle:
Principle #35Parameter changes

2Speed

If magnetic repelling force is used to accelerate separating process, then separation speed is improved, but mating process is interfered with

Engineering Contradiction:
Improveseparation speedVSAvoidmating operation
Core Design Contradiction:
SpeedVSEase of operation

Solution Approach 1:

The magnetic component's polarity is dynamically switched based on operational needs. During mating, the magnetic component maintains attracting polarity. During separation, the switching mechanism reverses the polarity to repelling. This dynamic adaptation eliminates the interference problem while maintaining fast separation capability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The magnetic force alternates between attracting and repelling states periodically according to the operational cycle. The switching mechanism activates repelling force only during the separation phase, then returns to attracting force for the next mating phase. This periodic action ensures that magnetic repulsion assists separation without interfering with mating.

Inventive Principle:
Principle #19Periodic action

3Device complexity

If conventional latch mechanism is used, then structural simplicity is maintained, but both mating and separation operations are slow

Engineering Contradiction:
Improvestructural simplicityVSAvoidoperation speed
Core Design Contradiction:
Device complexityVSSpeed

Solution Approach 1:

The magnetic component is integrated with the existing latch mechanism, merging two functions (mechanical latching and magnetic assistance) into a single system. The magnetic component works in conjunction with the latch to provide both mechanical retention and magnetic force assistance, achieving fast operation without requiring completely separate systems for mating and separation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The magnetic component acts as an intermediary that bridges the gap between mechanical latching and rapid operation. By introducing magnetic force as an intermediate mechanism, the system achieves fast mating and separation while maintaining the structural simplicity of the original latch design. The magnetic force supplements the mechanical action without replacing it entirely.

Inventive Principle:
Principle #24Intermediary (Mediator)

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.
