Sliding Camera Assembly with Magnetic Drive for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face challenges in providing a large screen display while accommodating camera functions, as existing camera assemblies are bulky and occupy valuable display space, limiting the expansion of the display area.
Innovation Solution
A camera assembly with a sliding mechanism using a magnetic structure and guiding device, allowing the camera module to extend outside the housing assembly, thereby reducing the occupied space and enhancing display area when not in use, and automatically retracting to prevent dust ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a camera assembly is integrated into a mobile terminal, then camera functionality is provided, but the display area is reduced due to the bulky camera structure occupying space
Solution Approach 1:
The camera assembly is designed with a sliding mechanism that allows it to dynamically change position between extended and retracted states. The support device can slide along the guiding device within the housing assembly, enabling the camera module to move from a retracted position (saving display space) to an extended position (providing camera functionality).
Solution Approach 2:
The camera assembly is nested within the housing assembly when not in use. The support device with the camera module slides within the guiding device that is integrated into the housing assembly, allowing the camera structure to be contained within the terminal body and not protrude outward, thereby maximizing the display area.
2Adaptability or versatility
If a sliding mechanism is added to enable camera extension, then camera functionality is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical drive systems (such as motors, gears, and linkages) with a simpler sliding mechanism. The support device slides along the guiding device within the housing assembly, using basic mechanical guidance rather than complex actuation systems, thereby reducing device complexity while maintaining camera functionality.
Solution Approach 2:
The camera assembly is divided into separate functional components: the housing assembly, the guiding device, and the support device with the camera module. This segmentation allows each component to perform its specific function independently, simplifying the overall structure and making the sliding mechanism easier to manufacture and assemble.
3Area of moving object
If the camera assembly is made compact to fit within housing, then display space is maximized, but dust protection becomes more difficult
Solution Approach 1:
The camera assembly is extracted from the display area when not in use by sliding it into a retracted position within the housing assembly. This extraction ensures that the camera module does not protrude from the terminal body, maintaining a compact form factor while the housing assembly provides dust protection for the retracted camera components.
Solution Approach 2:
The dynamic sliding mechanism allows the camera assembly to transition between extended and retracted states. When retracted, the camera module is positioned within the housing assembly where it is protected from dust and environmental factors, while still maintaining functionality when extended for use.

Function Achieved in This Case

Implementation Method 1

AI summary
The present disclosure provides a camera assembly and a mobile terminal. The camera assembly comprises a fixing frame, a support device, a guiding device, a camera module and a second magnetic structure. The support device has a first magnetic structure. The guiding device is connected to the fixing frame and the support device, respectively. The support device is slidably connected to the fixing frame by means of the guiding device. The camera module is arranged on the support device. The second magnetic structure is used for generating a magnetic field, and the second magnetic structure interacts with the first magnetic structure to apply a force to the support device in the sliding direction of the support device for sliding the support device. The support device slides under the guidance of the guiding device. This solution can achieve the purpose of enabling the camera module to freely protrude out of the mobile terminal.
