Rotating Camera Transmission Mechanism for Full-Screen Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face challenges in increasing the screen-to-body ratio while maintaining a diverse shooting scenario for cameras, as traditional telescopic camera arrangements are limited in versatility.
Innovation Solution
A mobile terminal design featuring a transmission mechanism with a driving mechanism, a first pushing member, a second pushing member, and a mounting seat, allowing the camera module to move between positions and rotate, enabling exposure from the terminal device and changing the camera's orientation to function as both front and rear cameras, thus increasing the screen-to-body ratio and enabling panoramic shooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a telescopic camera is arranged in a mobile terminal to increase screen-to-body ratio, then the screen-to-body ratio is improved, but the shooting scenario diversity deteriorates
Solution Approach 1:
The camera module is designed to be dynamically movable between different positions (retracted into mounting groove or exposed from side face) and rotatable around a rotating axis. This dynamic configuration allows the same camera module to serve multiple shooting scenarios including front camera, rear camera, and panoramic shooting modes, thereby resolving the contradiction between increasing screen-to-body ratio and maintaining shooting scenario diversity
Solution Approach 2:
A single camera module is designed to perform multiple functions by changing its position and orientation. When retracted, it serves as a front camera; when exposed and rotated to different angles, it serves as a rear camera or for panoramic shooting. This multi-functionality eliminates the need for separate front and rear cameras, thus increasing screen-to-body ratio while maintaining diverse shooting scenarios
2Device complexity
If a single camera module is used to function as both front and rear camera, then the device complexity is reduced, but the shooting versatility deteriorates
Solution Approach 1:
The mounting seat enables the camera module to rotate around a rotating axis that is perpendicular to the movement direction of the first pushing member. This rotational capability allows a single camera module to capture images from multiple orientations (front, rear, and panoramic modes), achieving shooting versatility equivalent to multiple cameras while reducing device complexity
Solution Approach 2:
The camera module transitions from a single-dimensional (fixed position) to a two-dimensional configuration by adding rotational movement around the rotating axis. This dimensional change enables the same camera module to access multiple shooting scenarios by varying its angular orientation, thereby maintaining versatility while using fewer components
