Toothed Rotating Assembly for Low-Cost Camera Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing photography and videography equipment requires expensive separate heads to adjust the angle of the photographing device, which increases economic pressure on users.
Innovation Solution
A rotating assembly with a head adjusting structure comprising a first button, first toothed disc, second toothed disc, and first elastic member, allowing the angle of the first head connector to be adjusted without a separate head, using a first button to overcome the elastic force and disengage teeth on the second toothed disc from the first toothed disc.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate head (ball head or pan head) is used to adjust the angle of the photographing device, then the angle adjustment function is reliable and stable, but the cost increases significantly
Solution Approach 1:
The patent merges the angle adjustment function directly into the supporting stand structure by integrating toothed discs and elastic members, eliminating the need for a separate head component. The first toothed disc and second toothed disc work together with elastic members to provide reliable angle adjustment while significantly reducing cost.
Solution Approach 2:
The elastic members automatically engage the teeth on the toothed discs to maintain the adjusted angle without requiring additional locking mechanisms or complex components. The system uses its own internal elastic force to hold the position, providing reliable angle retention with simple structure.
2Manufacturing precision
If a separate head is used for angle adjustment, then the adjustment precision is high, but the device complexity increases
Solution Approach 1:
The angle adjustment mechanism is segmented into discrete toothed discs with clearly defined teeth, where each tooth represents a discrete angle position. This segmentation provides precise angular positioning while keeping each individual component (toothed disc, elastic member) simple in structure.
Solution Approach 2:
The patent replaces expensive, complex heads with simple, inexpensive toothed discs and elastic members that can be easily manufactured. The simple structure of the toothed discs with basic teeth patterns allows for precise adjustment without requiring complex machinery or expensive materials.
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 cost-effective adjustment of the angle of the image acquisition apparatus mounted on the supporting stand, providing multiple usage modes such as handheld, high-position, low-position, and hung modes while reducing the need for expensive heads.
Implementation Method 1
the first elastic member is configured to enable teeth on the second toothed disc to mesh with teeth on the first toothed disc
Implementation Method 2
the first button is configured to overcome an elastic force of the first elastic member under the action of an external force

AI summary
Disclosed are a rotating assembly, a supporting stand, and a photographing device. The rotating assembly includes a head adjusting structure including a first button, a first toothed disc, a second toothed disc, and a first elastic member. The first toothed disc is fixedly connected with a first head connector. The first elastic member is configured to enable teeth on the second toothed disc to mesh with teeth on the first toothed disc. The first button is configured to overcome an elastic force of the first elastic member under the action of an external force, so that the teeth on the second toothed disc are disengaged from the teeth on the first toothed disc. The angle of the first head connector fixedly connected to the first toothed disc is adjusted by using the first button, the first toothed disc, the second toothed disc, and the first elastic member.
