Removable Belt Buckle With Integrated Clasp Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt buckles require the entire belt to be removed for detachment, which is inconvenient, especially when passing through security checkpoints, and existing removable buckles lack a simple mechanism within the buckle for quick and easy removal.
Innovation Solution
A removable belt buckle design featuring a frame, clasp, and restriction bar that allows the buckle to be quickly disconnected and reconnected without removing the belt from the waist, with the clasp mechanism housed within the buckle, enabling easy removal and reattachment without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the buckle is permanently attached to the belt strap, then the connection is strong and reliable, but the entire belt must be removed to detach the buckle which is inconvenient
Solution Approach 1:
The buckle system is divided into two separable components: a permanently attached portion (frame with prong) and a removable portion (clasp mechanism). The clasp can be detached from the frame without removing the entire belt, allowing selective separation while maintaining connection reliability through the permanent frame attachment.
Solution Approach 2:
The clasp mechanism is extracted as a separate removable component from the permanent frame. This allows the clasp to be taken out and stored independently while the frame remains attached to the belt, enabling buckle detachment without removing the entire belt strap.
2Object-affected harmful factors
If traditional metal snaps or fasteners are used to attach the buckle to the belt, then the connection is secure, but metal detectors are triggered at security checkpoints
Solution Approach 1:
The material composition of the fastening components is changed from metal to non-metal materials (such as plastic, polymer, or composite materials). This parameter change allows the buckle to function reliably while being non-magnetic and non-conductive, thus not triggering metal detectors at security checkpoints.
3Adaptability or versatility
If screws or toothed mechanisms are used to attach the buckle to the belt, then the attachment is strong, but repeated detachment causes permanent damage to the belt
Solution Approach 1:
The attachment mechanism transitions from a static permanent connection (screws, welded joints) to a dynamic reversible connection. The clasp uses movable components that can be opened and closed repeatedly without causing damage, allowing the buckle to be attached and detached multiple times while maintaining both strength and adaptability.
4Ease of operation
If a simple release mechanism is provided on the belt strap, then the buckle can be removed easily, but the release mechanism adds complexity to the belt
Solution Approach 1:
The release mechanism is merged into the buckle assembly rather than being separate components on both the belt and buckle. The clasp mechanism integrates the fastening and releasing functions within the buckle itself, simplifying the overall system while maintaining ease of operation.

AI summary
The buckle is made up of a frame, clasp and restriction bar. A prong protrudes from the backside of the frame to engage a hole in one end of the belt strap and the clasp releaseably connects the buckle to the opposite end. The clasp has a pair of fingers at one end and a pair of arms that extend to a joint at the opposite end. When the buckle is connected to the belt, the clasp and restriction bar engage one another. The clasp is biased towards a reduced angle by the restriction bar with the fingers situated within a loop at the end of the belt. Conversely, when the clasp disengages the restriction bar, the fingers separate as the joint biases the arms apart and the space between the fingers widens allowing the fingers to slide out of the loop and separate the buckle from the belt.
