Camera Device Five-Axis Stabilization Spherical Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera devices have limited anti-shake compensation, only covering four axes with a small compensation angle of ±1.5 degrees, and lack compensation for rotations parallel to the optical axis (roll). This restricts their application and increases complexity and cost due to the need for additional rotating structures and shafts.
Innovation Solution
A camera device with five-axis compensation is achieved by incorporating a driving component with magnets and coils that allow the second frame and camera component to rotate like a sphere, enabling pitch, yaw, and roll compensation. This is made possible by matching arc surfaces on the first and second frames, which reduces component interference and increases the compensation angle to ±3 degrees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera device uses a traditional four-axis anti-shake mechanism with limited rotation structures, then the device structure is relatively simple, but the compensation angle is small (±1.5 degrees) and the compensation scope is limited
Solution Approach 1:
The patent merges multiple rotation functions into a single integrated structure. The second frame simultaneously performs rotation around the first direction (pitch), second direction (yaw), and third direction (roll) axes, eliminating the need for separate rotating structures for each axis. This integration achieves five-axis compensation (pitch, yaw, roll, plus two linear directions) while reducing overall structural complexity
Solution Approach 2:
The patent employs spherical arc surfaces (first arc surface and second arc surface) that are concentric and matched to each other. The second frame rotates on the spherical surface of the first frame, enabling multi-directional rotation with a larger compensation angle of ±3 degrees. This spherical design allows the camera component to achieve five-axis stabilization without requiring complex mechanical shafts for each rotation axis
2Adaptability or versatility
If the camera device adds rotating structures and shafts for each axis to achieve five-axis compensation, then the compensation angle increases to ±3 degrees, but the device complexity and cost increase
Solution Approach 1:
The second frame serves multiple functions simultaneously: it holds the camera component, provides rotation around the first direction (pitch), rotation around the second direction (yaw), and rotation around the third direction (roll). This multi-functional design achieves five-axis compensation without requiring separate rotating structures and shafts for each axis, thereby reducing component count and complexity
Solution Approach 2:
The spherical arc surface design enables the second frame to rotate in multiple directions (pitch, yaw, roll) with a compensation angle of ±3 degrees. The concentric spherical surfaces provide the necessary geometric constraints for stable multi-axis rotation without requiring complex mechanical shafts, achieving both large compensation angle and reduced structural complexity
