Buckle With Split Female Member For Secure Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buckles with elastic plate-like parts face difficulties in secure engagement due to rigidity issues during operation, making the connection process challenging, and they lack sufficient space for design elements like logos on the buckle's front side.
Innovation Solution
The buckle design features a male and female member configuration where the second portion of the female member bends to facilitate easy engagement of the male member, with an engaging portion on the first portion that does not bend, ensuring a secure connection while allowing for easy release and accommodating design elements on the front side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rigidity of the elastic plate-like part is increased to make the connection secure, then the connection security is improved, but the ease of operation deteriorates because it becomes harder to bend during engagement
Solution Approach 1:
The female buckle member is divided into two distinct portions: a first portion that remains rigid to ensure secure connection, and a second portion that is flexible to facilitate easy engagement. This segmentation allows each portion to fulfill its specific function without compromise.
Solution Approach 2:
Different regions of the female buckle member are given different mechanical properties: the first portion has high rigidity for secure engagement, while the second portion has low rigidity for ease of operation. This local differentiation of material properties resolves the contradiction between security and ease of use.
2Ease of manufacture
If slits are formed on the front side of the female buckle member to enable engagement, then the engagement function is achieved, but the area available for logos and design elements is reduced
Solution Approach 1:
The engagement function is extracted from the first portion (front side) and relocated to the second portion (back side). By forming slits on the second portion rather than the first, the front side remains intact and available for logos and design elements while still achieving the required engagement functionality.
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
This design enhances the ease of connection and security of the buckle, allowing for a smooth engagement process with reduced insertion force and stable connection under tension, while also providing space for aesthetic features and logo display.
Implementation Method 1
a female member having a first portion and a second portion so as to receive a part of the male member between the first and second portions from one side by bending the second portion
Implementation Method 2
there is formed on the first portion an engaging portion for engaging with a corresponding engaging portion formed on the male member by bending back of the second portion at the final position of the engagement

AI summary
A buckle includes a male member, a female member for engaging with the male member and having a first portion and a second portion, a first engaging portion provided on the first portion, and a second engaging portion provided on the male member for engaging with the first engaging portion. The second portion can bend so as to receive a part of the male member between the first and second portions. The second portion presses the male member toward the first portion to engage the first engaging portion with the second engaging portion when the male member is inserted between the first and second portions.
