Rotating Camera Mounting Module for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals, such as smartphones, face challenges in achieving a high screen-to-body ratio due to the space occupied by front cameras, and rear cameras can compromise the integrity and appearance of the device.
Innovation Solution
A camera mounting module with a rotating base and driving mechanism that allows the camera to be housed within the device when not in use, exposing the camera lens only when needed, thereby optimizing space and preserving the device's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a front camera is equipped at the side where the display is located, then the camera function is achieved, but the display coverage is reduced and the screen-to-body ratio cannot be improved
Solution Approach 1:
The camera module is designed to be rotatable relative to the display, transitioning between a first position where the camera is received in the display area and a second position where the camera is exposed outside the display area. This dynamic positioning allows the display to have full coverage when the camera is not in use, while still providing camera functionality when needed.
Solution Approach 2:
The camera module is moved from a fixed planar position to a multi-position spatial configuration through rotation. The camera can be positioned in the first position (received in display area) or rotated to the second position (exposed outside display area), utilizing rotational movement to resolve the space conflict between display coverage and camera function.
2Reliability
If a rear camera is equipped in the rear housing, then the camera function is achieved, but the integrity and appearance of the rear housing is compromised
Solution Approach 1:
The camera module is designed to be rotatable relative to the display, transitioning between a first position where the camera is received in the display area and a second position where the camera is exposed outside the display area. This dynamic positioning allows the display to have full coverage when the camera is not in use, while still providing camera functionality when needed.
Solution Approach 2:
The rotatable camera module can serve multiple functions: when in the first position, it provides camera functionality while maintaining display coverage; when rotated to the second position, it exposes the camera for use. This single mechanism resolves both the display coverage issue and provides camera function without compromising housing integrity.
3Ease of operation
If the camera is always exposed outside the body, then the camera function is always available, but the screen-to-body ratio is reduced and appearance is compromised
Solution Approach 1:
The camera module is designed to be rotatable relative to the display, transitioning between a first position where the camera is received in the display area and a second position where the camera is exposed outside the display area. This dynamic positioning allows the display to have full coverage when the camera is not in use, while still providing camera functionality when needed.
Solution Approach 2:
The camera module can be periodically positioned in the exposed state when camera functionality is needed and returned to the received state when not needed. This periodic exposure maintains the screen-to-body ratio while providing camera availability on demand.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the screen-to-body ratio by minimizing camera-related space constraints and maintains the device's aesthetic integrity by allowing the camera to be hidden when not in use.
Implementation Method 1
a driving mechanism comprising an actuator, a first gear and at least one second gear, the at least one second gear being arranged between the first gear and the internal gear, the first gear and the at least one second gear being located within the internal gear; wherein the actuator is configured to drive the mounting base to rotate from a first position to a second position through the first gear, the at least one second gear and the internal gear

AI summary
A mobile terminal includes a body, a camera mounting assembly and a driving mechanism. The body includes a display and defines an accommodation slot. The camera mounting assembly includes a mounting base and a camera position in the mounting base. The mounting base is positioned in the accommodation slot. The driving mechanism includes an actuator and a gear driving structure. The actuator is configured to drive the mounting base to rotate from a first position to a second position through the gear driving mechanism. The camera is received in the accommodation slot when the mounting base is located in the first position and an incident surface of the camera is exposed out of the body when the mounting base is located in the second position.
