Ball Head Quick Release Locking Handle for Fast, Stable Camera Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera mounts with ball structures require multiple turns of a threaded knob for locking, which can lead to missed shooting opportunities, and press-type structures provide insufficient locking force, causing the camera to shake during use.
Innovation Solution
A quick release device with a locking handle that includes a screw block structure with tilted chutes and a screw guide, allowing for rapid locking and unlocking by rotating the handle once and pressing a button, enhancing locking force and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a threaded knob structure is used for locking, then the locking force is strong, but the locking operation time is long requiring multiple turns
Solution Approach 1:
The locking mechanism transitions from a static multi-turn threaded knob to a dynamic quick-release system. The button-actuated lever pivots between locked and unlocked positions, enabling rapid locking/unlocking operations while maintaining strong locking force through the lever's mechanical advantage against the connecting screw.
Solution Approach 2:
The invention extracts the essential locking function from the complex multi-turn threaded knob mechanism. By using a button-actuated lever that directly engages and disengages the connecting screw, the design removes unnecessary rotational movements while preserving the core locking capability.
2Loss of time
If a press-type structure is used for locking, then the locking operation time is short, but the locking force is insufficient causing camera shake
Solution Approach 1:
The lever pivots between locked and unlocked positions, creating a dynamic locking mechanism. When the button is released, the lever springs into the locked position, providing strong locking force through its mechanical engagement with the connecting screw, while the entire operation remains quick and efficient.
Solution Approach 2:
The lever incorporates a rounded end that engages with the connecting screw, allowing for smooth engagement and disengagement. This curved design facilitates quick operation while ensuring reliable mechanical contact and strong locking force when engaged.
3Force
If a threaded knob is used for locking, then the locking force is strong, but the operation complexity increases requiring multiple turns
Solution Approach 1:
The invention extracts the essential locking function from the complex multi-turn threaded knob mechanism. By using a button-actuated lever that directly engages and disengages the connecting screw, the design removes unnecessary rotational movements while preserving the core locking capability.
Solution Approach 2:
The lever system is self-actuating through the button mechanism. When the button is pressed and released, the lever automatically pivots into or out of the locked position using spring force, eliminating the need for manual multi-turn operations and simplifying the user interaction.
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
The device achieves strong locking with fewer turns, preventing camera shake and ensuring timely adjustments, thus improving shooting stability and efficiency.
Implementation Method 1
an elastic member disposed on one side of the screw block structure facing away from the ball structure, and an elastic force thereof drives the screw block structure to move along an axial direction of the connecting screw in the direction close to the ball structure

AI summary
A quick release device includes a tripod, a ball structure, a connecting screw securing to the ball structure, and a locking handle for locking and unlocking between the ball structure and the tripod. The locking handle includes a first cone locking handle, a screw structure with a second cone that is matched with the first cone locking handle. The screw structure includes a first screw and a second screw, where the first screw and the second screw are on opposite sides of the screw structure cooperating with each other to form a threaded hole structure. An outer wall of the screw structure is provided with an inclined chute, and the first cone locking handle is secured with a screw guide extending into the chute. The first cone locking handle is also connected to a pressing structure.
