Buckle With Pivotable Inserted Portion For Coupling Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buckles lack sufficient coupling strength while maintaining a thin design, as increasing thickness compromises the thinness objective.
Innovation Solution
The buckle design incorporates an elastically pivotable inserted portion with a groove at the base end, allowing for enhanced engagement and disengagement of the engaging and engaged portions, and a spring mechanism for manipulation, which increases coupling strength without significantly increasing thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the thickness dimension is increased to enhance coupling strength, then the coupling strength is improved, but the thinness of the buckle is deteriorated
Solution Approach 1:
The patent changes the geometric parameters of the inserted portion, specifically positioning the contact surface downward relative to the base end center point. This parameter change optimizes the force distribution and engagement mechanics, enabling enhanced coupling strength without increasing the overall thickness of the buckle
Solution Approach 2:
The patent introduces a downward position for the contact surface in the thickness direction, creating a multi-level engagement structure. This dimensional arrangement allows the contact surface to be positioned at a lower level than the base end, enabling improved coupling strength through spatial optimization rather than simply increasing thickness

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the coupling strength of the buckle while maintaining its thinness, ensuring effective engagement and disengagement through the use of a pivotable mechanism and groove configuration.
Implementation Method 1
the inserted portion, while having a thickness, extends from the base end to the free end, and is elastically pivotable around the base end as a pivot center to allow engagement and disengagement of the engaging and engaged portions

AI summary
A buckle includes a female part having a housing and an engaging portion provided at an inner surface of the housing, and a male part including a base and an inserted portion to be inserted into the housing of the female part. The inserted portion includes a base end coupled to the base, a free end opposite to the base end, and an engaged portion to be engaged with the engaging portion. When a force is applied to the male part for pulling the male part out of the housing, the engaged portion has a contact surface that is in contact with the engaging portion. Relative to a first center point at the center of the base end in the thickness direction of the inserted portion, a second center point at the center of the contact surface in the thickness direction is positioned downward.
