Lifting Rotating Camera Module for Full Screen Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The coexistence of rear and front camera modules in electronic devices increases device cost and occupies more space, as they are needed to achieve both full screen display and rear image capturing functionality.
Innovation Solution
A lifting and rotating assembly is used to eject and rotate the rear camera module to a front image capturing position, eliminating the need for a separate front camera module and allowing full screen display without a light transmission hole on the display surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both front and rear camera modules are provided, then both front and rear image capturing functions are achieved, but device cost and space occupation increase
Solution Approach 1:
The rear camera module is designed to perform both rear image capturing and front image capturing functions. By providing a lifting and rotating assembly, the same camera module can be positioned at different locations to serve different purposes, eliminating the need for separate front and rear camera modules and reducing device complexity and cost
Solution Approach 2:
The camera module is made dynamically positionable through the lifting and rotating assembly. The camera module can be lifted from the rear camera position to the front camera position and rotated to face forward, allowing the system to adapt its configuration based on operational requirements
2Adaptability or versatility
If a light transmission hole is provided on the display surface for front camera, then front image capturing is enabled, but the screen-to-body ratio is reduced
Solution Approach 1:
Instead of having a static light transmission hole in the display, the system uses a dynamic mechanism where the rear camera module is lifted and rotated to the front position. This eliminates the need for a permanent opening in the display surface, maintaining the screen-to-body ratio while enabling front image capturing functionality
Solution Approach 2:
The front camera function is extracted from the display surface by removing the light transmission hole requirement. The camera module is physically moved to the front position through the lifting and rotating assembly, separating the camera function from the display surface structure

AI summary
An electronic device includes a device body 100, a rear camera module 200, and a lifting and rotating assembly 300. A side enclosure 120 of the device body is provided with a camera extending-retracting hole. The rear camera module 200 is disposed in the device body 100 and can be ejected from or retracted into the device body through the camera extending-retracting hole. The lifting and rotating assembly 300 is connected with the rear camera module 200, and drives the rear camera module 200 to be ejected from the device body 100 through the camera extending-retracting hole and rotate to a front image capturing position.
