Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera modules in electronic devices have a fixed shooting angle, limiting their scenario adaptation and imaging quality due to poor image stabilization when the device moves.
Innovation Solution
A lens carrying device with a base, rotating support, swinging support, and lens support, driven by multiple drivers to adjust the lens's angle, enabling a large field of view and image stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lens and lens tube are fixed in conventional camera modules, then the structure is simple and easy to manufacture, but the shooting angle range is fixed and scenario adaptation capability is poor
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed lens structure into a multi-degree-of-freedom rotatable structure. The lens support can rotate around a first axis via a rotating support, and around a second axis via a swinging support, enabling dynamic adjustment of the shooting angle. This dynamic structure allows the camera module to adapt to different scenarios by changing the lens orientation without moving the entire device.
Solution Approach 2:
The patent segments the camera module into multiple independent rotatable components: a base, a rotating support that can rotate around the first axis, a swinging support that can rotate around the second axis, and a lens support that holds the lens. Each component can be independently controlled by separate driving assemblies, allowing flexible and independent adjustment of each degree of freedom to achieve various shooting angles.
2Reliability
If the camera module moves synchronously with the electronic device, then the structure is simple, but the image stabilization performance is poor when the device moves
Solution Approach 1:
The patent implements image stabilization by enabling the lens support to independently rotate and adjust its position relative to the base through the rotating support and swinging support mechanisms. When the electronic device moves, the driving assemblies can actively adjust the lens orientation to compensate for the movement, maintaining stable imaging performance without requiring the entire camera module to move with the device.
3Adaptability or versatility
If multiple driving assemblies are added to enable lens rotation and swinging, then the scenario adaptation capability is improved, but the device complexity increases
Solution Approach 1:
The patent divides the control system into separate driving assemblies for different degrees of freedom: a first driving assembly controls rotation around the first axis, a second driving assembly controls rotation around the second axis, and a third driving assembly provides additional rotational control. Each driving assembly independently controls a specific component, simplifying the control logic and enabling precise adjustment of each degree of freedom.
Solution Approach 2:
The patent designs the driving assemblies to be potentially interchangeable or multi-functional components that can control different aspects of the lens positioning system. This universal design approach allows the same type of driving mechanism to be used for different rotational axes, reducing the variety of unique components needed and simplifying manufacturing and maintenance.
