Clothing Belt Buckle With Rotating Convex Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buckles for clothing belts that rely on friction for adjustment are prone to loosening under external forces due to the lack of a secure frictional force and unsuitable design for formal wear, as they require a clearance for the hook portion which compromises frictional contact and aesthetic appeal.
Innovation Solution
A buckle design featuring a base body with sliding shafts and rotating bodies with convex portions that securely fix the belt by generating a strong frictional force through overlapping and bending, eliminating the need for a hook portion and enhancing the buckle's appearance for formal wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the belt is fixed by generating frictional force between the belt and the buckle through tension, then the buckle structure is simple and easy to operate, but the belt is likely to loosen when the buckle receives external forces other than tension
Solution Approach 1:
The buckle employs dynamic elements including a rotatable first rotating body with a first convex portion that can rotate between engaged and disengaged positions, and a second rotating body with a second convex portion that rotates to lock or release the first rotating body. This dynamic mechanism allows the belt to be securely fixed during wear while enabling easy adjustment and release through rotational movements.
Solution Approach 2:
The buckle combines multiple functional components with different properties: the base body provides structural support, the first rotating body generates frictional force through its convex portion contacting the belt, and the second rotating body provides locking functionality. This composite structure integrates friction-based fixation with mechanical locking to achieve both ease of operation and reliability.
2Reliability
If a hook portion is provided in the buckle for securing the belt, then the belt fixation is reliable, but the buckle requires additional clearance space compromising the aesthetic appearance for formal wear
Solution Approach 1:
The invention extracts and eliminates the traditional hook portion from the buckle structure. Instead of using a protruding hook that requires clearance space, the design employs a compact rotating body mechanism where the first convex portion and second convex portion create securing action within the confines of the base body, achieving reliable fixation without compromising aesthetic appearance.
Solution Approach 2:
The invention transitions from a linear hook-based securing mechanism to a rotational dimension. The first and second rotating bodies utilize rotational movement around shafts to achieve belt fixation, transforming the securing action from a linear protrusion into a rotational engagement that maintains a sleek profile suitable for formal wear.
3Adaptability or versatility
If the first rotating body is allowed to move freely to adjust belt length, then the belt length can be steplessly adjusted, but the rotating body may move unintentionally under external forces
Solution Approach 1:
The second rotating body with its second convex portion is designed to preemptively counteract unintended movement of the first rotating body. When the first rotating body rotates to a position where the second convex portion engages with it, this preliminary anti-action prevents any further unintended rotation, thereby stabilizing the belt length while preserving stepless adjustability during intentional operation.
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 effectively prevents unintentional loosening under external forces and provides a strong, reliable frictional fixation, suitable for Western-style clothing, while maintaining a design suitable for formal occasions by generating friction over a wider area and eliminating the need for a hook portion.
Implementation Method 1
the first convex portion in close contact with a surface of the clothing belt and the open end portion of the first rotating body in close contact with a surface of the clothing belt
Implementation Method 2
the second convex portion of the second rotating body is positioned on a path of movement of a shaft side end portion of the first rotating body that moves with a sliding of the first shaft

AI summary
According to one aspect of the present invention, a buckle for a clothing belt includes a first rotating body supported by the first shaft so as to be rotatable, an open end portion of the first rotating body being capable of being disposed between a bar and a back plate of a base body by making a first shaft slid; and a second rotating body supported by a second shaft so as to be rotatable with the second shaft as a fulcrum, formed so as to have a second convex portion, and capable of hindering a movement of the first rotating body in a direction opposite to the bar side with the second convex portion in a state where the second convex portion is rotated so as to be pushed in toward the opening portion of the back plate.
