Rotating Camera Module for Full-Screen Mobile Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and limited screen-to-body ratio of mobile phones due to the need for multiple cameras and inconsistent pixel effects between front and rear cameras, which affect user experience.
Innovation Solution
A camera assembly with a camera module, front shaft device, and forward turning drive device that allows the camera to pivot, enabling multiple capture angles without the need for separate lenses at different view directions, thus reducing costs and improving pixel consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras are used to achieve both front camera function and rear camera function, then camera functions are enriched, but costs increase and device complexity increases
Solution Approach 1:
The patent applies the dynamics principle by making the camera module rotatable around a shaft. The camera module can dynamically change its orientation between facing upward (for rear camera function) and facing forward (for front camera function). This dynamic positioning allows a single camera to perform multiple functions that previously required separate fixed cameras, thereby reducing device complexity while maintaining versatile camera capabilities.
2Adaptability or versatility
If multiple cameras are used to achieve both front camera function and rear camera function, then camera functions are enriched, but costs increase
Solution Approach 1:
The patent implements universality by designing a single camera module that can serve multiple purposes. By rotating the camera module between different orientations, it can function as both a rear camera (when facing upward) and a front camera (when facing forward). This multi-functionality eliminates the need to purchase and install separate front and rear camera components, thereby reducing costs while maintaining enriched camera functions.
3Adaptability or versatility
If a front camera is provided in the display screen, then front camera function is achieved, but screen-to-body ratio is limited
Solution Approach 1:
The patent uses the dynamics principle to enable the camera module to rotate between facing upward and facing forward positions. When the camera module rotates to face forward, it performs the front camera function without requiring a fixed opening in the display screen. This dynamic repositioning eliminates the need to compromise the screen-to-body ratio, as the front camera function is achieved through rotation rather than through a permanent screen opening.

AI summary
A camera assembly includes a camera module, a front shaft device, and a forward turning drive device. The camera module includes a strip-shaped body, and the strip-shaped body includes a front end portion, a rear end portion, and a lens located at a top of the strip-shaped body between the front end portion and the rear end portion. The front shaft device includes at least one front shaft, and each front shaft is adapted to pivotally engaging with the front end portion. The front shaft pivotally engages with the front end portion, and the forward turning drive drives the camera module to pivot forward around the front shaft, so that the camera module rotates to be in a front capture state where the rear end portion is lifted and the lens finds views forward.
