Sliding Camera Module for High Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to increase the screen-to-body ratio of mobile phones while accommodating camera devices on the front face, which typically limits the display layout space.
Innovation Solution
A mobile terminal design featuring a slidable device with cameras that can retract into a groove, allowing the display screen to occupy more space when the cameras are not in use, thereby enhancing the screen-to-body ratio and enabling flexible camera usage without obstructing the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If camera devices are arranged on the front face to provide better user experience, then camera functionality is improved, but the screen-to-body ratio deteriorates due to limited layout space
Solution Approach 1:
The camera module is designed to be movable between a retracted position (within the groove) and an extended position (outside the groove). This dynamic configuration allows the camera to occupy space only when needed, resolving the contradiction between providing camera functionality and maintaining a high screen-to-body ratio.
Solution Approach 2:
Instead of placing the camera on the front face (2D plane), the camera is positioned in a groove that extends from the front face toward the rear face (3D space). This dimensional change allows the camera to be accessed when needed without permanently occupying front face space, thus maintaining the screen-to-body ratio.
2Adaptability or versatility
If the slidable device is extended outward to expose both cameras, then camera functionality is improved, but the device complexity increases
Solution Approach 1:
The camera module is segmented into a slidable device that can be independently moved from the main terminal body. This segmentation allows the complex slidable mechanism to be isolated as a separate module, making the overall system more manageable and maintainable.
Solution Approach 2:
The slidable device serves multiple functions: it houses both the first and second cameras, provides a unified moving structure for camera exposure, and can be controlled to expose either or both cameras based on operational needs. This multi-functionality reduces the need for separate mechanisms for each camera.

AI summary
A mobile terminal may include left and right side faces (101, 102), front and rear side faces (103, 104), and top and bottom faces (105, 106). A groove (10) may be defined in the mobile terminal, and penetrate the left and right side faces (101, 102). The mobile terminal may include a slidable device (1), a first display screen (21), a first camera (31), and a second camera (32). The first display screen (21) may be arranged on the front side face (103), and the first camera (31) and the second camera (32) may be arranged on the slidable device (1). When the slidable device (1) slides into the groove (10), the first camera (31) is blocked and the second camera (32) may be exposed; when the slidable device (1) slides out of the groove (10), the first camera (31) and the second camera (32) may be both exposed.
