Camera Bracket Bolt Assembly for Precise T-Direction Alignment
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 not sufficient to meet required precision needs.
Innovation Solution
A camera bracket with a rotatory adjustment mechanism that includes a fine adjustment bolt assembly, allowing for precise T-direction angle adjustments by aligning a fine adjustment threaded hole with a limiting hole, enabling finer control over the camera's angle through a coaxial connection and arc-shaped guiding surface for optimal alignment.
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 camera bracket can overcome gravity and maintain stable positioning, but the minimum adjustment angle is limited to 7.2° which is insufficient for telephoto cameras requiring higher precision
Solution Approach 1:
The adjustment mechanism is divided into two independent parts: the tooth slot engagement mechanism for coarse adjustment and the fine adjustment bolt assembly for precise adjustment. This segmentation allows each component to perform its specific function optimally - the tooth slots provide stable positioning with 7.2° increments, while the fine adjustment bolt enables continuous small-angle adjustments, thereby achieving high precision without requiring complete redesign of the entire mechanism
Solution Approach 2:
The fine adjustment bolt assembly acts as an intermediary component between the tooth slot mechanism and the camera mounting interface. It translates rotational motion into precise linear displacement that adjusts the camera angle, bridging the gap between the coarse tooth slot positioning and the requirement for fine angular adjustment, thus enabling precision control without directly modifying the tooth slot structure
2Measurement precision
If the minimum adjustment angle is reduced to meet precision requirements, then telephoto cameras can achieve required accuracy, but the adjustment mechanism becomes more complex
Solution Approach 1:
The patent merges two adjustment functions into one integrated mechanism: the tooth slot engagement provides the primary positioning function, while the fine adjustment bolt assembly provides the precision adjustment function. Both functions operate within the same mechanical structure, allowing users to first use the tooth slots for rough positioning and then use the fine adjustment bolt for precise alignment, combining simplicity and precision in a single operation sequence

Function Achieved in This Case
The camera bracket achieves precise T-direction angle adjustments, meeting the required accuracy standards by allowing for adjustments beyond the 7.2° minimum, ensuring the camera's angle can be finely tuned to meet specific requirements.
Implementation Method 1
The fine adjustment bolt assembly includes a fine adjustment bolt provided with a threaded portion and a limiting portion, and the fine adjustment bolt passes through the limiting hole, and the threaded portion is threadedly connected to the fine adjustment threaded hole
