Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera modules have a fixed and excessively small view angle due to non-deflectable lens assemblies, limiting their photographic capabilities.
Innovation Solution
A camera module design featuring a fixing member, a photographing unit connected via a connection shaft, and a driving component comprising magnetic and conductive members that generate a driving force to rotate the photographing unit within a magnetic field, allowing for adjustable view angles without the need for transmission mechanisms, thus increasing the camera's view angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lens assembly is fixed and cannot be deflected, then the structure is simple and stable, but the view angle is excessively small
Solution Approach 1:
The lens assembly is transformed from a fixed structure to a movable one by introducing a connection shaft that allows the photographing unit to rotate relative to the fixing member. This dynamic configuration enables the lens assembly to deflect and adjust its optical path, thereby increasing the view angle while maintaining structural simplicity through the use of a single rotational degree of freedom.
2Adaptability or versatility
If traditional mechanical transmission mechanisms are used to deflect the lens assembly, then the view angle can be increased, but the device volume and power consumption increase
Solution Approach 1:
The patent replaces complex mechanical transmission mechanisms with a direct magnetic driving system. A magnetic member fixed to the fixing member interacts with a conductive member on the photographing unit to generate driving force through electromagnetic interaction. This substitution eliminates the need for gears, belts, or other mechanical transmission components, thereby reducing the device volume and power consumption while achieving the desired lens assembly deflection.
3Adaptability or versatility
If the photographing unit is made movable to increase view angle, then the camera capabilities are improved, but the location accuracy and transmission efficiency may be compromised
Solution Approach 1:
The patent incorporates a feedback mechanism where the controller receives feedback information about the photographing unit's position or status and adjusts the driving component accordingly. This feedback loop ensures that the photographing unit returns to or maintains the correct position during operation, thereby preserving location accuracy and transmission efficiency while enabling the view angle to be increased through controlled movement.

AI summary
A camera module, an electronic device and a photographing method are disclosed, which relates to the field of camera devices, in order to mitigate or alleviate the problem of an excessively small view angle for the existing camera module. The camera module includes a fixing member, a photographing unit connected with the fixing member via a connection shaft, a driving component including a first magnetic member and a first conductive member. Either of the first magnetic member and the first conductive member is fixed to the photographing unit, the other is fixed to the fixing member. The first conductive member is arranged to be located in a magnetic field of the first magnetic member so as to generate, when the first conductive member is energized, a driving force capable of driving the photographing unit to rotate around the connection shaft in the magnetic field of the first magnetic member.
