Camera Platform Locking Device with Differential Thread Pitch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera platform locking devices lack distinct regulation capabilities, as the primary and secondary regulating assemblies share the same screw bolt and thread, making it difficult to achieve different regulation purposes with the same angle of rotation, leading to unclear regulation effects and reduced precision.
Innovation Solution
The camera platform locking device incorporates a primary and secondary regulating assembly with reversely structured screw threads and inclined surfaces, along with a damping assembly, allowing for distinct moving distances and high regulation accuracy, while preventing the camera legs from being blocked during folding by optimizing the angle and size of the locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the primary and secondary regulating assemblies share the same screw bolt and thread, then the structure is simplified, but the regulation precision and distinction between primary and secondary regulation are reduced
Solution Approach 1:
The patent divides the single screw bolt into two separate screw bolts (primary screw bolt and secondary screw bolt) with different thread pitches. This segmentation allows each regulating assembly to have independent control over the sphere's position, with the primary assembly providing coarse adjustment and the secondary assembly providing fine adjustment, thereby resolving the contradiction between structural simplicity and regulation precision.
2Ease of manufacture
If the primary and secondary regulating assemblies use the same screw thread pitch, then the manufacturing is simplified, but the ability to achieve different regulation purposes with the same rotation angle is lost
Solution Approach 1:
The patent applies local quality by giving the primary and secondary screw bolts different thread pitches (different local characteristics) while keeping them structurally similar. The primary screw bolt has a larger thread pitch for coarse regulation, while the secondary screw bolt has a smaller thread pitch for fine regulation. This allows each assembly to be optimized for its specific regulation purpose while maintaining manufacturing feasibility through the use of standard screw bolt designs.
3Volume of moving object
If the locking mechanism is made compact to reduce size, then the space efficiency is improved, but the regulation accuracy may be compromised
Solution Approach 1:
The patent employs a nested structure where the secondary regulating assembly is integrated within the primary regulating assembly. The secondary screw bolt and its driving component are positioned inside the housing structure of the primary assembly, allowing both regulating mechanisms to coexist in a compact space. This nesting approach maintains the distinct thread pitches and regulation capabilities of both assemblies while minimizing the overall volume of the locking mechanism.

Function Achieved in This Case
This design enables clear differentiation in regulation purposes, maintains high-speed movement, and ensures precise positioning of the camera platform, while reducing the overall size and height of the locking mechanism, enhancing both regulation accuracy and space efficiency.
Implementation Method 1
the primary screw bolt has two screw threads that are reversely structured to each other; two primary driving components having inclined surfaces are in threaded connection with corresponding screw threads on the primary screw bolt
Implementation Method 2
two primary driving components having inclined surfaces are in threaded connection with corresponding screw threads on the primary screw bolt; the inclined surfaces of the two primary driving components are oppositely arranged to each other, for driving the sphere to move up and down through their reverse movement
Implementation Method 3
a damping assembly, arranged underneath the sphere, for providing a damping to the upward and downward movement of the sphere
