Rotating Camera Module with Arc Groove and Sliding Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in mobile terminal design is to improve the screen ratio while accommodating a rotatable camera without compromising the device's appearance, as a large rotation gap is necessary to avoid interference with other mechanisms, which affects the overall aesthetics.
Innovation Solution
A mobile terminal design featuring a mounting base with an arc-shaped groove and a restriction post that allows the camera module to rotate between hidden and exposed positions, minimizing the gap and maintaining appearance integrity, using a sliding fit mechanism to achieve this rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large rotation gap is provided for the camera to rotate, then the camera can avoid interference with other mechanisms, but the overall appearance of the mobile terminal is adversely affected
Solution Approach 1:
The patent employs an arc-shaped groove instead of a straight linear path for the camera module's rotation mechanism. This curved geometry allows the camera to rotate between front and rear positions while following a compact arc trajectory, significantly reducing the linear space required and minimizing the gap needed for rotation, thereby preserving the device's appearance integrity.
Solution Approach 2:
The camera module is nested within the mounting base, which itself is integrated into the terminal housing. The mounting base contains the arc-shaped groove that guides the restriction post, creating a nested structure where the camera assembly is housed within a compact mechanism that rotates along a curved path, reducing the overall space requirement.
2Area of stationary object
If a rotatable camera mechanism is implemented, then the screen ratio can be improved, but the device complexity increases
Solution Approach 1:
The mounting base serves multiple functions: it houses the camera module, provides the arc-shaped groove for rotation guidance, contains the restriction post mechanism, and integrates with the terminal housing. This multi-functional design consolidates several components into a single assembly, reducing overall device complexity despite the rotatable camera functionality.
Solution Approach 2:
The patent merges the camera module, mounting base, restriction post, and arc-shaped groove mechanism into an integrated assembly. The mounting base combines structural support, rotation guidance, and camera housing functions, simplifying the overall mechanism compared to having separate components for each function.
3Reliability
If the camera module rotates out from the front face, then the camera can function effectively, but dust or water may enter the device
Solution Approach 1:
The mounting base acts as a protective shell that encloses the camera module during rotation. The arc-shaped groove is defined within the mounting base structure, creating a enclosed pathway that protects the camera module from dust and water ingress while allowing it to rotate between front and rear positions.

Function Achieved in This Case
This design enhances the screen ratio by minimizing the space required for camera rotation, improving the device's appearance and reducing the likelihood of dust or water entry, while allowing the camera to function effectively without occupying screen area.
