Spherical Camera Module With Nested Rotating Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera gimbals for mobile terminals face issues with interference in viewing angles due to rotating arms and increased volume, limiting omnidirectional capturing capabilities within a compact space.
Innovation Solution
A camera module with a spherical main body and multiple rotatable arms, each equipped with motors, allowing independent rotation in a three-dimensional space for omnidirectional capturing, featuring a first arm connected to the main body with a first motor, a second arm connected to the first arm with a second motor, and a fixing member connected to the second arm with a third motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional camera gimbal uses multiple rotating arms to achieve omnidirectional capturing, then capturing capability is improved, but device volume increases and arms interfere with viewing angles
Solution Approach 1:
The patent implements a nested structure where the first arm is disposed inside the second arm, and the third arm is disposed inside the fourth arm. This nesting arrangement allows multiple rotating arms to occupy overlapping spatial volumes, significantly reducing the overall camera module volume while maintaining the capability for omnidirectional capturing through independent rotation of each arm around a common center point
Solution Approach 2:
The patent transitions from conventional planar arm arrangements to a three-dimensional nested configuration where arms rotate around a common center point in multiple dimensions. This dimensional change allows arms to interfere less with viewing angles while achieving omnidirectional coverage, as each arm operates in a different spatial dimension around the central axis
2Adaptability or versatility
If conventional camera gimbal uses multiple rotating arms for omnidirectional capturing, then capturing capability is improved, but arms interfere with each other's viewing angles
Solution Approach 1:
By nesting arms within each other around a common center point, the patent minimizes the radial footprint of each arm. This allows arms to rotate without colliding or blocking each other's viewing paths, as they occupy concentric spatial zones rather than overlapping planar spaces
Solution Approach 2:
The patent divides the omnidirectional capturing function into multiple independent arm segments, each capable of autonomous rotation. This segmentation allows each arm to operate independently without interfering with others, as each arm can be controlled to avoid blocking critical viewing angles while collectively achieving full omnidirectional coverage
