One-Handed Inserting Buckle With Dual Pressing Buckles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inserting buckles require simultaneous operation with both hands to separate the insertion piece and the buckle part, making them inconvenient to use.
Innovation Solution
An inserting buckle design featuring a buckle body with a cavity, an ejection member, and two movable pressing buckles driven by elastic members, allowing the connection portion to be ejected with simultaneous one-handed operation by pressing the first and second pressing buckles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the insertion piece is separated from the buckle part by pressing two elastic arms simultaneously with one hand, then the ease of operation is improved, but the device complexity increases due to the addition of ejection member and pressing buckles
Solution Approach 1:
The buckle body is divided into multiple functional components: a stationary buckle part, a movable connection portion, an ejection member, and two pressing buckles. This segmentation allows the complex separation function to be distributed across independent components, where each component has a specific role in achieving one-handed operation while maintaining overall system functionality.
Solution Approach 2:
The ejection member is pre-positioned within the buckle body, ready to eject the connection portion when activated. The pressing buckles are pre-configured to transmit finger pressure to the connection portion. This preliminary arrangement enables the separation action to be triggered by a simple pressing motion without requiring complex real-time coordination mechanisms.
2Productivity
If the ejection member and pressing buckles are added to enable one-handed operation, then the productivity is improved through faster separation, but the manufacturing precision requirements increase
Solution Approach 1:
The connection portion is designed to move dynamically between two states: inserted/locked within the buckle body and ejected/removed. The pressing buckles and ejection member work together to create a dynamic separation mechanism that transitions smoothly from the locked state to the separated state, enabling rapid one-handed operation while maintaining controlled movement throughout the process.
Solution Approach 2:
The ejection member is designed to automatically eject the connection portion when the pressing buckles are activated, without requiring additional manual manipulation. The elastic arms and pressing mechanism work together in a self-contained system where the user's pressing action directly triggers the ejection sequence, reducing the need for precise manual coordination and simplifying the operational process.
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
Enables convenient and practical separation of the buckle part from the insertion piece by automatically ejecting the connection portion with one-handed operation, enhancing usability.
Implementation Method 1
the first pressing buckle is movably disposed in the cavity and driven back by a first elastic member
Implementation Method 2
the second pressing buckle is movably disposed in the cavity and moved toward or away from the first pressing buckle; the second pressing buckle is driven back by a second elastic member

AI summary
An inserting buckle includes an insertion piece, a buckle body, an ejection member, a first pressing buckle and a second pressing buckle. The second pressing buckle movably disposed in the cavity and moved toward or away from the first pressing buckle; the second pressing buckle is driven back by a second elastic member; a buckle hole is formed between the first pressing buckle and the second pressing buckle; the connection portion is inserted into the cavity and is locked in the buckle hole; the first pressing buckle and the second pressing buckle are simultaneously pressed to enlarge an width of the buckle hole, the connection portion is separated from the buckle hole, the ejection member ejects the connection portion out of the cavity. The operation of separating the buckle body and the insertion piece only needs to simultaneously press the first button and the second button with one hand.
