Retractable Camera Mechanism for Mobile Terminal Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for large-screen displays in mobile terminals is hindered by the limited space available due to the need to accommodate components like cameras on the front face, which restricts the screen-to-body ratio.
Innovation Solution
A mobile terminal design featuring a support assembly with a bendable member, a first housing, and a second housing, where the camera is retractably mounted in a moveable seat within an accommodation slot or space, allowing the camera to be exposed or retracted to improve screen-to-body ratio by optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If camera components are arranged on the front face of the mobile phone, then image capturing function is achieved, but screen-to-body ratio is reduced due to limited arrangement space
Solution Approach 1:
The camera module is designed to be movable rather than fixed, allowing it to extend when needed for image capture and retract when not in use. This dynamic positioning enables the camera to occupy space only when functional, thereby maintaining a high screen-to-body ratio while preserving full image capturing capability.
Solution Approach 2:
The camera module transitions from a two-dimensional plane arrangement on the front face to a three-dimensional extension along the thickness direction. By moving the camera along the Z-axis (thickness direction), the design eliminates the need to compromise the front face display area, achieving both high screen-to-body ratio and functional camera capability.
2Area of stationary object
If display screen area is increased to meet user demand for large-screen displaying, then user experience is improved, but arrangement space for components is reduced
Solution Approach 1:
The camera module is positioned along the thickness direction rather than occupying front face area, effectively utilizing the Z-axis dimension. This dimensional transition allows the display screen to maximize the X-Y plane area while the camera module occupies space in the thickness direction, resolving the conflict between screen size and component arrangement.
Solution Approach 2:
The movable camera module can be extended or retracted along the thickness direction, allowing the front face to be dedicated to the display screen when the camera is retracted. This dynamic design enables maximum display area while maintaining the capability to accommodate the camera component when needed.
3Weight of moving object
If the mobile phone is designed with a thin and lightweight form factor, then portability is improved, but space for accommodating camera is reduced
Solution Approach 1:
The camera module is designed to be nested within the mobile phone housing when retracted, utilizing the existing structural space along the thickness direction. This nesting approach allows the camera to be accommodated within the thin profile of the mobile phone without requiring additional external volume, maintaining both portability and camera functionality.
Solution Approach 2:
The movable camera module can be extended only when needed for image capture, and retracted to minimize the overall thickness when not in use. This dynamic configuration allows the mobile phone to maintain a thin and lightweight form factor for portability while still providing adequate space for the camera component when required.

AI summary
The present disclosure provides a mobile terminal. The mobile terminal includes a support assembly, a display screen, and a moveable seat. The support assembly includes a first housing, a second housing, and a bendable member. The bendable member is connected between the first housing and the second housing. The first housing is provided with a protrusion. The first housing defines an accommodation slot therein. The second housing is provided with a concave groove. When the support assembly is folded, at least a part of the protrusion is accommodated within the concave groove. A camera is disposed in the moveable seat. The moveable seat is retractably mounted in the accommodation slot, and the moveable seat carrying the camera is configured to be received within the accommodation slot or extended out of the accommodation slot so that an image capturing face of the camera is exposed.
