Detachable Camera Module for Full-Screen Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The space occupied by the front camera in mobile terminals limits the screen ratio of mobile phones, hindering the realization of full-screen designs.
Innovation Solution
A detachable camera module that can be installed on a mobile terminal, featuring a main board with a battery and a capturing assembly, allowing the camera to be housed within the terminal's structure without occupying display space, enabling wireless connectivity for increased screen ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the front camera is integrated into the mobile terminal body, then the camera functionality is available, but the screen ratio is reduced due to occupied display space
Solution Approach 1:
The camera module is separated from the mobile terminal body into an independent detachable unit. The terminal body and camera module can be used independently or combined, allowing the camera to provide functionality without permanently occupying display space when detached
Solution Approach 2:
The camera module is positioned in a different spatial dimension relative to the terminal body - it can be attached to the side or back of the device rather than integrated into the front display area, thus not reducing the screen ratio when the camera is not in use
2Area of stationary object
If a detachable camera module is used, then the screen ratio is increased, but the device complexity increases due to additional mounting and connection mechanisms
Solution Approach 1:
The mounting structure serves multiple functions: it provides mechanical attachment, electrical connection through contact pads, and structural support. The same contact pads used for mounting also serve as electrical contacts for power and data transmission, reducing the need for separate connection mechanisms
Solution Approach 2:
The electrical connection components are integrated into the mounting structure itself. The contact pads are formed on the mounting plate, combining the mechanical mounting function with the electrical connection function in a single integrated component
3Area of stationary object
If the camera module is detachable, then wireless connectivity is enabled for increased screen ratio, but the reliability of connection may be affected
Solution Approach 1:
The mounting structure with contact pads serves as an intermediary that provides both mechanical stability and electrical connection. This intermediary component ensures reliable wired connection when attached, while wireless communication protocols handle the wireless connectivity requirement
