Rotating Self-Locking Clip Structure for Secure Mobile Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photography clips lack a self-locking function, leading to insecure clamping and a high risk of accidental release when used with mobile devices.
Innovation Solution
A clip design featuring a seat, pressing plate, and rotation assembly with a protruding inclined surface, allowing for a clamping slot to be closed and locked by a rotation assembly abutting against the inclined surface, enhancing clamping security through increased static friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clip uses a simple clamping structure without self-locking function, then the device complexity is low, but the clamping security and reliability are insufficient
Solution Approach 1:
The pressing plate is designed to rotate between a release position and a clamping position, transforming the static clamping structure into a dynamic one. This rotation mechanism allows the clip to transition from an open state to a locked state, providing self-locking functionality while maintaining operational simplicity
Solution Approach 2:
The rotation assembly with the protruding inclined surface creates a self-locking mechanism where the geometric shape itself provides the locking action. When the pressing plate rotates to the clamping position, the inclined surface automatically engages with the rotation assembly, creating friction-based locking without requiring additional active components
2Reliability
If the clip lacks self-locking function, then the ease of operation is high, but the risk of accidental release increases
Solution Approach 1:
The protruding inclined surface on the pressing plate is designed to preemptively engage with the rotation assembly before any accidental release can occur. This preliminary engagement creates a friction-based barrier that prevents unintended opening, while the deliberate rotation mechanism remains easily operable by user intent
3Force
If the pressing plate rotates to clamp the rabbit cage, then the clamping force increases, but the stability against unintended rotation must be maintained
Solution Approach 1:
The protruding inclined surface utilizes curved or angled geometry to create a wedge-like effect. As the pressing plate rotates, this inclined surface engages with the rotation assembly, generating increased clamping force through mechanical advantage while the friction between the curved surfaces prevents unintended rotation back

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 design provides improved clamping security by ensuring the clip remains locked and stable, preventing accidental release of mobile devices during use.
Implementation Method 1
the rotation assembly is abutted against the protruding inclined surface through rotation... the movable clamping portion is pressed to lock the clip

AI summary
Disclosed are a clip and a photography kit. The clip includes: a seat, a pressing plate and a rotation assembly. One end of the seat is a fixed clamping portion; the pressing plate rotatably is provided on the seat, one end of the pressing plate is a movable clamping portion, the pressing plate is provided with a protruding inclined surface, the protruding inclined surface has a highest point and a lowest point, and a continuous inclined surface is provided between the lowest point and the highest point of the protruding inclined surface. The rotation assembly is abutted against the protruding inclined surface through rotation. The fixed clamping portion is cooperated with the movable clamping portion to form a clamping slot, and the pressing plate is configured to rotate on the seat to open or close the clamping slot.
