Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held electronic devices often produce poor-quality pictures due to shaking during camera use, as existing camera modules lack effective anti-shake mechanisms.
Innovation Solution
A camera assembly featuring a bracket body, a spherical part, and a first driving mechanism with rolling elements that rotate to counteract camera shake, ensuring the camera remains stable and focused by rotating in synchronization with the spherical part, thereby enhancing image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera module is used for hand-held shooting, then the electronic device can capture images, but the picture quality deteriorates due to shaking
Solution Approach 1:
The patent implements a dynamic anti-shake mechanism where the camera module is mounted on a movable platform that can rotate in multiple directions. Driving mechanisms actively adjust the camera's position and orientation in real-time to counteract shaking movements, transforming the static camera mounting into a dynamic stabilization system that maintains picture quality during hand-held shooting
Solution Approach 2:
The patent employs counterbalancing mechanisms where weights or counteracting forces are introduced to offset the shaking movements. The driving mechanisms generate opposing rotational movements that counterbalance the unwanted camera shake, effectively neutralizing the destabilizing forces during hand-held operation
2Reliability
If anti-shake mechanisms are added to the camera module, then picture quality improves, but device complexity increases
Solution Approach 1:
The patent integrates the anti-shake driving mechanisms directly into the camera module structure, merging the stabilization function with the existing camera assembly. The driving sources are incorporated within the module housing, and the movable platform is seamlessly integrated with the mounting bracket, combining multiple functions into a unified structure rather than adding separate complex subsystems
Solution Approach 2:
The camera module design incorporates multi-functional components where the mounting bracket serves both structural support and rotation pivot functions, the movable platform provides both positioning and stabilization, and the driving mechanisms handle multiple axes of stabilization. This multi-functionality reduces the need for separate dedicated components for each function

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The anti-shake mechanism effectively compensates for camera shake, improving picture quality by maintaining a perpendicular light incidence, reducing electromagnetic interference, and providing a wide range of anti-shake angles, resulting in clearer and more reliable images.
Implementation Method 1
The rolling element is in contact with a spherical surface of the spherical part and rolls relative to the spherical surface
