Rotating Buckle Structure for One-Pull Release and Reattachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices are cumbersome to remove and reattach due to the need to rotate a buckle by a predetermined angle and then pull it away from the structure, making the process inefficient.
Innovation Solution
A rotating buckle design featuring a first and second fixing member, a hook body, and resilient members that allow the buckle to be easily disengaged and reattached by pulling or pushing the second fixing member, enabling lateral movement and rotation of the hook body, simplifying the operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the buckle is removed by rotating it by a predetermined angle and then pulling it away, then the buckle can be disengaged from the structure, but the fixing and removing process becomes cumbersome
Solution Approach 1:
The buckle mechanism transitions from a static rotation-then-pull operation to a dynamic pull-to-rotate operation. The resilient member dynamically converts linear pulling force into rotational motion, allowing the buckle to automatically rotate and disengage when pulled, thereby simplifying the user operation while maintaining the disengagement function
Solution Approach 2:
The buckle mechanism performs self-rotation when pulled by the user. The resilient member automatically converts the pulling force into rotational motion, causing the buckle to rotate and disengage without requiring the user to manually rotate it first. This self-service mechanism eliminates the need for complex manual manipulation steps
2Ease of operation
If the buckle structure is simplified for easier operation, then the fixing and removing process becomes more convenient, but the stability and reliability of the connection may be compromised
Solution Approach 1:
The buckle is segmented into distinct functional components: a body portion for connection, a resilient member for force conversion, and a rotating mechanism for disengagement. This segmentation allows each component to perform its specific function efficiently - the resilient member ensures reliable connection during normal use, while the rotating mechanism provides simple one-pull disengagement when needed
Solution Approach 2:
The connection mechanism transitions from a static rigid connection to a dynamic system where the resilient member can deform and the buckle can rotate. During normal use, the system maintains a stable connected state. When pulled, the resilient member dynamically converts the force to rotate the buckle, enabling easy disengagement while maintaining reliability during operation

AI summary
A rotating buckle includes a first fixing member, a second fixing member, and a hook body. The first fixing member includes protruding posts. The second fixing member defines limiting slots and comprises a fixing portion. The fixing portion fixes the second fixing member to the first fixing member through a first resilient member. The hook body is received between the first fixing member and the second fixing member. The hook body defines a mounting hole, an inclined slot, and a receiving slot. The protruding posts are inserted through the mounting hole, the inclined slot, and the limiting slots. The fixing portion is inserted through the receiving slot. The hook body is fixed to the first fixing member through a second resilient member.
