Rotating Camera Module for High Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminal designs face challenges in efficiently utilizing space to switch between front and rear camera functions while maintaining a high screen-to-body ratio.
Innovation Solution
A terminal device with a mounting base that can rotate between two positions, allowing the camera module to be exposed either at the rear or front side of the device, enabling seamless switching between front and rear camera operations without occupying the display area, thus enhancing usability and saving component costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a front camera is provided on the side of the mobile terminal where the display area is located, then the camera can function as a front camera, but it is difficult to make the front camera serve as a rear camera and occupies the display area
Solution Approach 1:
The camera module is made movable through a rotating assembly that can switch between a first position (front camera) and a second position (rear camera). This dynamic repositioning allows the same camera hardware to serve dual functions, resolving the contradiction between camera versatility and display area occupation.
Solution Approach 2:
A single camera module is designed to perform multiple functions by rotating to different positions. The camera can function as both a front camera and a rear camera, eliminating the need for separate camera modules and thereby preserving display area while achieving camera function switching.
2Adaptability or versatility
If separate front and rear camera modules are provided, then both camera functions are available, but the device complexity increases and space utilization is reduced
Solution Approach 1:
One camera module is designed to perform the functions of both front and rear cameras by rotating to different positions. This universal design reduces device complexity by eliminating the need for separate camera modules, connection interfaces, and control systems while maintaining full camera functionality.
Solution Approach 2:
The functions of separate front and rear camera modules are merged into a single rotating camera assembly. This consolidation reduces the number of components, simplifies the overall device structure, and improves space utilization while maintaining both camera functions.
3Area of stationary object
If the camera module is fixed at the front side, then the screen-to-body ratio can be maintained, but the camera cannot be used as a rear camera
Solution Approach 1:
The camera module transitions from a fixed position to a dynamically repositionable assembly that can rotate between front and rear positions. This dynamic capability allows the camera to be used in both front and rear configurations without permanently occupying display area, thereby maintaining screen-to-body ratio while improving camera versatility.
