Dual Ball-Head Camera Support for Wider Rotation Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustment support assemblies for surveillance cameras have limited rotatable angles, which fail to meet the needs of consumers for broader coverage.
Innovation Solution
The assembly includes a first shell, a second shell, a first ball head, a second ball head, and a ball head connecting rod, where the first and second ball heads are fixed at the ends of the connecting rod and rotatably arranged within their respective shells, allowing for increased rotational range by frictional action, expanding the range of rotation between the shells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single ball head is used to connect the base and camera shell, then the structure is simple, but the rotatable angle range is limited
Solution Approach 1:
The patent divides the adjustment mechanism into two separate ball heads (first ball head and second ball head) instead of using a single ball head. Each ball head is independently arranged in its own fixing portion, allowing them to function as separate rotational joints. This segmentation enables the camera shell to rotate relative to the base through the coordinated action of both ball heads, significantly expanding the rotatable angle range while maintaining reasonable structural complexity
Solution Approach 2:
The patent implements a nested structure where the first ball head is arranged within the first ball head fixing portion in the base, and the second ball head is arranged within the second ball head fixing portion in the camera shell. The ball head connecting rod connects these nested ball heads, creating a compact multi-level adjustment mechanism that achieves extended rotation range without proportionally increasing overall device size or complexity
2Area of stationary object
If a single ball head is used for adjustment, then the device complexity is low, but the surveillance coverage is insufficient
Solution Approach 1:
By segmenting the adjustment mechanism into two independent ball heads, the patent enables the camera to achieve broader surveillance coverage. The first ball head provides rotation in one direction while the second ball head provides rotation in another direction, allowing the camera to cover a larger angular area and monitor more locations effectively
Solution Approach 2:
The patent transitions from a single-degree-of-freedom adjustment mechanism to a two-degree-of-freedom mechanism by adding the second ball head. This dimensional change in the adjustment mechanism allows the camera to rotate in multiple directions independently, significantly expanding the surveillance coverage area without requiring an overly complex mechanism
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
This configuration significantly enhances the rotatable angle range of the adjustment support assembly, enabling broader surveillance coverage compared to single-ball-head solutions.
Implementation Method 1
By controlling the rotation of the ball head, the camera shell rotates under the action of friction force of the ball head
