Sliding Camera Mounting Box for High Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen mobile phones face limitations in increasing screen-to-body ratio due to the occupation of space by front-facing electronic devices such as camera components, earpiece, and light sensors on the front face.
Innovation Solution
A mobile terminal design featuring a sliding mounting box mechanism that allows the camera to retract into a receiving groove, thereby exposing or hiding the camera lens, and using a driving device to extend or retract the mounting box, ensuring the camera does not occupy display screen area and improving the screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If front-facing electronic devices (camera, earpiece, light sensors) are disposed on the front face of the mobile terminal, then the camera can be easily accessed for photography, but the screen-to-body ratio is reduced due to space occupation
Solution Approach 1:
The camera module is designed to be movable rather than fixed on the front face. The mounting box can slide along the longitudinal axis of the terminal, transitioning between extended and retracted states. This dynamic positioning allows the camera to be accessible when needed while maintaining a clean front face with maximum screen area when retracted.
Solution Approach 2:
Instead of placing the camera on the front face (2D surface), the patent moves the camera to a different spatial dimension by using a longitudinal sliding mechanism. The camera module extends from the rear or side of the terminal along the length axis, effectively removing it from the front face plane and allowing unlimited screen area on the front surface.
2Area of stationary object
If the camera module is made movable to improve screen-to-body ratio, then the screen area increases, but the device complexity increases due to additional sliding mechanism
Solution Approach 1:
The camera assembly is segmented into an independent mounting box that can move separately from the main terminal body. This modular design isolates the complexity of the sliding mechanism to a separate component (mounting box with guides and drive) rather than integrating it into the main terminal structure, making the overall system more manageable.
Solution Approach 2:
The mounting box serves multiple functions: it houses the camera module, provides the sliding mechanism for movement, offers protection when retracted, and enables positioning adjustment. By consolidating these functions into a single component, the patent reduces the number of separate parts needed and simplifies the overall structure despite the added mobility feature.
3Ease of operation
If the camera is exposed continuously for easy photography, then the camera is always accessible, but privacy security is compromised due to accidental exposure
Solution Approach 1:
The camera module transitions between exposed and hidden states dynamically. When not in use, the mounting box retracts into the terminal body, hiding the camera and preventing accidental exposure. When photography is needed, the user can extend the mounting box to access the camera. This dynamic state change provides both security and accessibility as needed.
Solution Approach 2:
The camera module is pre-positioned in a retracted state within the terminal body, already in the secure hidden position before use. The user must actively extend it to access the camera, creating a preliminary secure state that prevents accidental exposure while allowing intentional access when required.

AI summary
The disclosure provides a mobile terminal (100) including a middle frame (20), a main board (30), a display screen module (60), a back plate (80), and a mounting box (41). The display screen module (60) includes a display screen (62) and a positioning frame (64). The positioning frame (64) is disposed on a front side face (21) of the middle frame (20). The back plate (80) is disposed on a back side face (22) of the middle frame (20). A receiving groove (27) is defined by a top face (26) of the middle frame (20), the display screen module (60) and the back plate (80). The mounting box (41) includes a front flange (4135) and a back flange (4145). A first camera (410) is disposed at the mounting box (41). The mounting box (41) is extended out of or retracted into the receiving groove (27). When the mounting box (41) is retracted into the receiving groove (27), the front flange (4135) overlies the positioning frame (64) and the back flange (4145) overlies the back plate (80).
