Rotating Prism Camera Module for Full-Screen Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with a large screen-to-body ratio are hindered by the need for a non-display region opening to accommodate camera modules, limiting the increase in screen-to-body ratio due to the physical requirement for a camera module installation.
Innovation Solution
A photographing device with a prism mechanism that rotates to extend outside the device for photographing and retract inside when not in use, allowing for a compact design that eliminates the need for a non-display area on the screen, utilizing a base, elastic mechanism, and driving mechanism to control the prism's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera module is installed in the non-display region of the display screen, then the camera module can function properly, but the screen-to-body ratio is limited and cannot be increased
Solution Approach 1:
The camera module is designed with a movable structure that allows it to switch between an extended state (for photographing) and a retracted state (within the device body). This dynamic configuration enables the camera to function when needed while maintaining a compact form factor when not in use, thereby increasing the screen-to-body ratio without compromising camera functionality
Solution Approach 2:
Instead of placing the camera module in the traditional non-display region of the screen (2D plane), the invention extends the camera module outward from the device body in a third dimension. This spatial reconfiguration allows the display area to occupy the entire front surface while the camera module is positioned in an extended dimension, resolving the contradiction between full-screen display and camera functionality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables an increased screen-to-body ratio by allowing the camera module to operate without occupying non-display screen space, enhancing user experience through improved design efficiency and space utilization.
Implementation Method 1
an elastic mechanism (40) coupled between the base (10) and the prism mechanism (20)
Implementation Method 2
Light incident on the incident surface (20a) is internally reflected to the light emitting surface (20b) and is emitted from the light emitting surface (20b)

AI summary
A photographing device able to not requiring installation and space in a non-display area of an electronic device includes a base, a prism mechanism, and a photosensitive mechanism. The base includes a receiving groove, and inclined first and second stop surfaces. The prism mechanism is rotatably coupled to the base, accommodated in the receiving groove, and includes incident and light-emitting surfaces at right angles. The first and second stop surfaces are in the rotation path of the light emitting surface. The photosensitive mechanism includes a photosensitive surface parallel to the first stop surface. When the light emitting surface resists against the first stop surface, the light emitting surface faces the photosensitive surface, and at least part of the incident surface is located outside the receiving groove. When the light emitting surface resists against the second stop surface, the incident surface is accommodated in the receiving groove.
