Rotatable Camera Module for High Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with large screen-to-body ratios face limitations in improving user experience due to the layout of functional components like camera and receiver modules, which occupy space and reduce portability.
Innovation Solution
A rotatable module with a camera and receiver module mounted in a rotatable base, allowing these components to be folded or unfolded to communicate with a receiver window, optimizing space usage and improving portability without needing signal-penetrating portions on the display module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If functional components (camera module and receiver module) are fixed in the device body, then the device structure is simple and stable, but the screen-to-body ratio is reduced and portability is compromised
Solution Approach 1:
The camera module and receiver module are mounted on a rotatable base that can rotate between a folded state (where components are retracted into the device body) and an unfolded state (where components extend outward). This dynamic configuration allows the device to maintain a high screen-to-body ratio when folded while providing access to functional components when unfolded, resolving the contradiction between structural stability and screen-to-body ratio.
Solution Approach 2:
The rotatable base with camera and receiver modules can be nested within the device body when in the folded state, allowing functional components to be contained within the device's footprint. This nesting approach maximizes the screen-to-body ratio while maintaining access to all functional components, as they can be deployed outward when needed.
2Ease of operation
If signal-penetrating portions are added to the display module for camera and receiver functions, then functional access is improved, but manufacturing complexity and cost increase
Solution Approach 1:
Instead of integrating camera and receiver modules directly into the display module (which would require signal-penetrating portions and complex manufacturing), the patent extracts these functional components and mounts them on a separate rotatable base. This allows the display module to remain simple and easy to manufacture, while functional access is achieved through the external rotatable structure that can be positioned as needed.
3Volume of moving object
If the rotatable module is folded, then portability and compactness are improved, but the receiver module cannot communicate with the receiver window
Solution Approach 1:
The rotatable base dynamically adjusts the position of the receiver module between folded and unfolded states. When folded, the device achieves compactness for portability. When unfolded, the receiver module extends to communicate with the receiver window, ensuring reliable signal transmission. This dynamic positioning resolves the contradiction between compactness and communication reliability.

AI summary
An electronic device is provided. The electronic device includes a device body and a rotatable module. The rotatable module is rotatably connected to the device body. The device body defines a receiver window. The rotatable module includes a rotatable base, a camera module, and a receiver module, where the camera module and the receiver module are mounted in the rotatable base. The receiver module defines a first sound-guide channel on a side of the receiver module and a second sound-guide channel on an opposite side of the receiver module. The first sound-guide channel is in communication with the receiver window when the rotatable module is folded with respect to the device body, and the second sound-guide channel is in communication with the receiver window when the rotatable module is unfolded with respect to the device body. A control method of an electronic device is also provided.
