Sliding Camera Module Driven by Electromagnetic Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals face challenges in achieving full-screen displays due to the need for a hole in the screen to accommodate camera modules, which reduces the display-to-screen area ratio.
Innovation Solution
A camera assembly with a sliding mechanism using a magnet and electromagnetic element allows the camera module to move between an extended and retracted position, eliminating the need for a permanent hole in the screen by using a guiding system and slots to facilitate movement within the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hole is defined on the glass substrate of the screen to accommodate the camera module, then the camera module can be exposed for signal penetration, but the display area ratio of the screen is reduced
Solution Approach 1:
The camera module is made movable between a retracted position (inside the main body) and an exposed position (outside the main body) through a sliding mechanism driven by electromagnetic elements. This dynamic positioning allows the screen to be continuous without holes when the camera is retracted, while still enabling camera functionality when exposed.
Solution Approach 2:
The camera module is extracted from the screen area and placed in a separate sliding assembly that can move independently. The camera module is housed in a sliding bracket that travels along guiding elements, separating the camera function from the display surface and eliminating the need for a permanent hole in the screen.
2Reliability
If the camera module is permanently exposed through the screen, then camera functionality is always available, but the device volume increases and display continuity is lost
Solution Approach 1:
The camera module transitions from a static permanently-exposed configuration to a dynamic sliding mechanism. The electromagnetic driving structure enables the camera to move between retracted and exposed positions on demand, maintaining camera functionality while minimizing device volume and preserving display continuity when the camera is not in use.
Solution Approach 2:
The camera module is nested within the sliding bracket, which itself is nested within the main body when retracted. This nested arrangement allows the camera to be compactly stored inside the device volume, only extending outward when needed, thereby reducing overall device volume while maintaining full camera functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution increases the display area-to-total screen area ratio, reduces the device's volume, and enhances user experience by allowing the camera to be hidden when not in use, thus enabling a more seamless and larger display.
