Quick-Release Clasp Ring for Secure Cylindrical Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lens tripod rings are inconvenient to use due to the need to rotate the screw locking member several turns to fix or loosen the components, making the process time-consuming.
Innovation Solution
A ring with a switch mechanism that allows for the fixation or release of components by rotating the abutting member less than 360 degrees, typically 90 degrees, using an arc-shaped abutting member and a protrusion to engage or disengage the second element, facilitating quick adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw locking member is used to fix the two components, then the connection is reliable, but the operation time is excessive due to multiple rotations required
Solution Approach 1:
The locking member is designed to rotate only 90 degrees or less to transition between locked and unlocked states. The abutting member engages with the protrusion at specific angular positions to provide stable locking at 0-90 degree rotation, transforming the static multi-turn screw mechanism into a dynamic quick-release system that maintains reliability while dramatically reducing operation time
Solution Approach 2:
The rotational parameter of the locking member is changed from multiple turns (conventional screw mechanism) to a limited 90-degree or less rotation. The abutting member's angular position relative to the protrusion serves as the control parameter, enabling rapid state transitions between locked and unlocked positions without sacrificing connection reliability
2Reliability
If a screw locking member is used to fix the two components, then the fixing is secure, but the ease of operation is poor due to multiple rotations required
Solution Approach 1:
The locking mechanism transitions from a static multi-turn screw system to a dynamic quick-release system where the abutting member engages the protrusion at specific angular positions (0-90 degrees). This dynamic engagement provides secure locking while enabling rapid one-handed operation, significantly improving ease of operation without compromising fixing security
Solution Approach 2:
The rotational movement is segmented into discrete angular positions rather than continuous multi-turn rotation. The abutting member engages the protrusion at specific segments of the rotation (0-90 degrees), creating distinct locked and unlocked states that are easy to identify and operate, thereby improving ease of operation while maintaining secure fixing

AI summary
A ring for clasping a cylindrical object includes a first element, a second element and a switch mechanism. The second element is circumferentially butted with the first element, and one end of the first element is adjacent to one end of the second element. The end of the second element has a protrusion protruding outwardly. The switch mechanism includes an abutting member adjacent to the end of the first element and configured to be rotated to abut against or move away from the protrusion of the end of the second element. When the abutting member is rotated and abuts against the protrusion of the end of the second element, the second element is fixed; when the abutting member is rotated and moves away from the protrusion of the end of the second element, the second element is released.
