Sliding Camera Mount for Mobile Terminal Screen Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen mobile phones face limitations in screen-to-body ratio due to the presence of front-facing components like cameras, earpieces, and light sensors, which occupy space on the front face, hindering the increase in screen area and compromising visual experience.
Innovation Solution
A mobile terminal design featuring a middle frame with a receiving groove for a sliding mounting box that houses camera and earpiece components, allowing these to retract into the frame, thus freeing up space for a larger display screen and enhancing security by preventing accidental exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If front-facing components (camera, earpiece, light sensor) are disposed on the front face of the mobile terminal, then these components can perform their functions, but the screen-to-body ratio is limited due to the space occupied by these components
Solution Approach 1:
The mounting box is designed to be slidable relative to the middle frame, allowing the camera component to dynamically change position between an exposed state (for photography) and a retracted state (for maximizing screen-to-body ratio). This dynamic configuration resolves the contradiction by enabling both full screen display and camera functionality at different times.
Solution Approach 2:
The invention moves the camera component from the traditional front-face plane to a three-dimensional sliding mechanism that extends perpendicular to the screen surface. The camera can protrude from the front face when needed and retract into the middle frame when not in use, utilizing the depth dimension to resolve the space occupation issue.
2Reliability
If the camera component is always exposed on the front face, then camera functions are always accessible, but unauthorized access and privacy security are compromised
Solution Approach 1:
The sliding mounting box enables the camera to dynamically transition between exposed and retracted states. When retracted, the camera is hidden within the middle frame, preventing unauthorized access and ensuring privacy security. When extended, the camera becomes accessible for legitimate photography operations.
3Area of stationary object
If the mounting box is made slidable to allow camera exposure and retraction, then screen-to-body ratio is improved and security is enhanced, but the device complexity increases
Solution Approach 1:
The mounting box integrates multiple functions including camera housing, sliding mechanism, and positioning structure into a single unified component. This merging approach reduces the number of separate parts and simplifies the overall structure, thereby minimizing the increase in device complexity while still achieving the desired slidable functionality.

AI summary
The present disclosure provides a mobile terminal (100) including a middle frame (20), a main board (30), a display screen module (60), and a back plate (80). The middle frame (20) includes a front side face (21), a back side face (22), a left side face (23), a right side face (24), and a top face (26). The display screen module (60) is disposed on the front side face (21). The back plate (80) is disposed on the back side face (22). A receiving groove (27) is defined by the top face (26) of the middle frame (20), the display screen module (60) and the back plate (80). The mobile terminal (100) further includes a mounting box (41) slideably received in the receiving groove (27). A first camera (410) is disposed at a side face of the mounting box (41) that faces the display screen module (60). The mounting box (41) is extended out of or retracted into the receiving groove (27) so that the first camera (410) is exposed out of or hidden into the receiving groove (27).
