Rotating Protrusible Camera Module for High Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current terminal devices with high screen-to-body ratios face challenges in achieving optimal front camera imaging quality without increasing costs, as larger front cameras negatively impact the screen-to-body ratio and imaging effectiveness.
Innovation Solution
A camera module with a first driving assembly for rotation and a second driving assembly for protrusion, utilizing electric motors and transmissions to position the camera assembly for improved imaging while maintaining a high screen-to-body ratio, reduces costs by eliminating the need for a dedicated front camera and ensuring stable image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a larger front camera is used to improve imaging quality, then imaging quality is improved, but the screen-to-body ratio deteriorates
Solution Approach 1:
The patent implements a movable camera assembly that can rotate and protrude from the terminal body. The camera assembly transitions from a retracted state (maintaining high screen-to-body ratio) to a protruded state (enabling high-quality imaging). This dynamic configuration allows the system to optimize both screen-to-body ratio and imaging quality at different operational states, resolving the contradiction between these two parameters.
2Adaptability or versatility
If a dedicated front camera is added to improve front image capturing, then front image capturing capability is improved, but device complexity increases
Solution Approach 1:
The patent employs a single camera assembly that serves multiple functions: it acts as a rear camera when in the rear position and as a front camera when rotated to the front position. The camera assembly can capture images from different directions and angles without requiring separate dedicated front and rear camera modules. This multi-functional design reduces device complexity while maintaining versatile imaging capabilities.
Solution Approach 2:
The patent combines the functions of front and rear cameras into a single camera assembly. By integrating both front-facing and rear-facing imaging capabilities into one unified module that can rotate and reposition, the system eliminates the need for separate camera components, thereby reducing overall device complexity while achieving comprehensive imaging functionality.
