Pop-up Camera Ejection Assembly for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods to enhance the screen ratio of mobile phones, such as independent pop-up cameras and bone conduction technology, either compromise the device's appearance or result in poor sound quality and user experience.
Innovation Solution
An ejection assembly for mobile terminals comprising a driving mechanism, decorative members, and lifting mechanisms that allow the camera module to retract flush with the screen assembly and back cover, eliminating steps and improving aesthetics and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If an independent pop-up camera is used to increase screen ratio, then the screen ratio is improved, but a hole must be defined in the housing and the camera protrudes out affecting the overall appearance
Solution Approach 1:
The camera module is designed to dynamically change its position between protruding (for photography function) and retracted (for appearance) states. The lifting mechanism enables the camera to move vertically, allowing it to be flush with the housing when not in use, thereby eliminating the need for a visible hole and improving overall appearance while maintaining full photography functionality.
2Shape
If bone conduction technology is used to avoid defining a hole in the housing, then the appearance is improved, but the sound quality is poor
Solution Approach 1:
The camera module is extracted from the traditional fixed-position design and separated into a movable component. By taking the camera out of the housing plane and allowing it to protrude when needed, the invention achieves both goals: the housing maintains a clean appearance without holes when the camera is retracted, and the camera can extend to provide full photography functionality when required.
3Area of stationary object
If a front camera is arranged at the bottom to increase screen ratio, then the screen ratio is improved, but the user experience is poor
Solution Approach 1:
Instead of arranging the camera at the bottom edge (two-dimensional plane arrangement), the invention moves the camera into the third dimension by allowing it to protrude from the housing. This vertical dimensionality change enables the camera to be positioned optimally for photography while maintaining a clean housing appearance, thereby improving user experience without compromising screen ratio.

AI summary
An ejection assembly for a mobile terminal is disclosed. The mobile terminal includes a back cover and a screen assembly covering the back cover. The ejection assembly includes: at least one driving mechanism; a first decorative member; a second decorative member, opposite to and spaced apart from the first decorative member, wherein the first decorative member and the second decorative member are movable toward each other or away from each other; and at least one lifting mechanism, disposed between the first decorative member and the second decorative member; each of the at least one lifting mechanism being connected to the corresponding driving mechanism; driven by the at least one driving mechanism, the at least one lifting mechanism is capable of driving the first decorative member and the back cover to move away from each other, such that the first decorative member is substantially flush with the screen assembly, and the second decorative member is substantially flush with the back cover. A mobile terminal having the ejection assembly is further disclosed. The screen ratio is improved without affecting the overall appearance of the mobile terminal.
