Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buckles face difficulties in easy connection and rotation of components due to the use of telescopic or torsion springs, which are hard to accommodate, and the male and female connection members are troublesome to fasten with straps at desired angles.
Innovation Solution
A buckle structure featuring a male buckle with an accommodation cavity, two fastening arms with V-shaped abutting faces, and a resilient sheet that allows easy connection and secure retention, along with rotatable connection members for adjustable angles, enhancing the ease of assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If telescopic spring or torsion spring is used in the male connection member, then the hooks can be removed quickly, but the spring is difficult to accommodate in the male connection member
Solution Approach 1:
The patent extracts the spring element from the male connection member entirely. Instead of using a telescopic or torsion spring within the male member, the invention uses a resilient sheet that is retained by the female connection member, separating the resilient function from the male member's hook mechanism.
Solution Approach 2:
The patent introduces a resilient sheet as an intermediary element between the male and female connection members. This resilient sheet, with its contacting segments and convex arc face, mediates the interaction between the two members, providing the necessary resilient force without requiring a spring to be housed within the male member.
2Ease of manufacture
If through holes are defined on the male connection member and female connection member, then the straps can be connected, but the components cannot rotate to the desired angle and fastening is troublesome
Solution Approach 1:
The patent transforms the static through-hole connection into a dynamic system. The resilient sheet with its contacting segments and convex arc face enables the male and female connection members to rotate relative to each other while maintaining the connection, allowing adjustment to desired angles.
Solution Approach 2:
The patent changes the geometric parameters of the connection interface. Instead of simple cylindrical through-holes, the invention uses V-shaped abutting faces and a convex arc face that accommodate rotational movement while maintaining structural integrity and connection stability.
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
The buckle structure allows for easy connection and secure fastening of straps with adjustable angles, reducing fabrication costs and improving usability by using a resilient sheet and rotatable components.
Implementation Method 1
the resilient sheet includes a convex arc face and two contacting segments arranged on two ends of the resilient sheet respectively... the two contacting segments are biased against the two first abutting faces of the two fastening arms separately

AI summary
A buckle structure contains a male buckle, two fastening arms, and a resilient sheet. The male buckle includes a first opening, a second opening opposite to the first opening, an external fence, and an accommodation cavity, wherein the external fence has two first orifices. Each of the two fastening arms includes a through hole, an engagement portion, a first abutting face, a second abutting face, and a column rotatably connected with the first orifice and the through hole so that the first abutting face and the second abutting face are located in the accommodation cavity of the male buckle, and the engagement portion of each fastening arm extends out of the first opening of the male buckle. The resilient sheet is formed in a U shape and includes a convex arc face and two contacting segments arranged on two ends of the resilient sheet respectively.
