Camera Bracket Fine Adjustment for Precise T-Direction Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera bracket systems lack sufficient accuracy in T-direction angle adjustment, particularly for telephoto cameras, as the minimum adjustment angle of 7.2° is insufficient to meet required precision needs.
Innovation Solution
A camera bracket with a rotatory adjustment mechanism that includes a fine adjustment bolt assembly and a coaxial connection assembly, allowing for precise adjustment of the camera's T-direction angle by aligning a fine adjustment threaded hole with a limiting hole, enabling finer adjustments beyond the initial tooth slot increments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed tooth slot and rotatory tooth slot engagement mechanism is used for T-direction angle adjustment, then the structure is simple and easy to operate, but the minimum adjustment angle is large (7.2°) and insufficient for high-precision requirements
Solution Approach 1:
The adjustment mechanism is divided into two independent parts: a coarse adjustment mechanism (tooth slot engagement) for large-angle adjustments and a fine adjustment mechanism (threaded hole and bolt) for precise small-angle adjustments. This segmentation allows each part to optimize its function without compromising the other.
Solution Approach 2:
A fine adjustment plate with a limiting hole is introduced as an intermediary component between the tooth slot mechanism and the camera mounting. This plate provides a reference position and enables the fine adjustment threaded hole to work in conjunction with the coarse adjustment mechanism, achieving both simplicity and precision.
2Ease of operation
If the minimum adjustment angle is increased to 7.2° for easier operation, then the device is easier to operate, but the positioning accuracy for telephoto cameras becomes insufficient
Solution Approach 1:
The adjustment mechanism transitions from a static tooth-to-tooth engagement to a dynamic system where the fine adjustment bolt can continuously vary the angle within the limits of the limiting hole. This dynamic capability allows for both easy coarse adjustment and precise fine-tuning.
Solution Approach 2:
The system changes the adjustment parameter from discrete tooth increments (7.2°) to continuous threaded rotation, allowing the adjustment precision to be varied from coarse (tooth level) to fine (thread level) depending on the operational needs.

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 camera bracket achieves precise T-direction angle adjustments, meeting the required accuracy standards by allowing incremental adjustments smaller than the initial tooth slot increments, thereby enhancing the camera's positioning capabilities.
Implementation Method 1
The fine adjustment bolt passes through the limiting hole, and the threaded portion is threadedly connected to the fine adjustment threaded hole
