Pop-Up Camera Elevating Mechanism for Narrow-Bezel Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with camera modules integrated into the front bezel face challenges in achieving an extremely thin bezel due to the need for space, which hinders the realization of an edge-to-edge front screen display.
Innovation Solution
An elevating mechanism comprising a main frame, an elevating frame, and an accommodation frame that allows the camera to be positioned behind the screen, enabling it to be elevated and angled, thus eliminating the need for camera placement in the front bezel, allowing for a nearly edge-to-edge display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the camera module is integrated into the front bezel, then the camera function is achieved, but the bezel width cannot be reduced to achieve edge-to-edge display
Solution Approach 1:
The camera module is made movable through an elevating mechanism that allows it to pop up from a retracted position to an active shooting position. The accommodation frame can rotate between a first position (retracted) and a second position (extended), transforming the static camera integration into a dynamic system that achieves both thin bezel and camera functionality.
Solution Approach 2:
Instead of placing the camera module in the traditional planar front bezel area, the invention utilizes the vertical dimension by retracting the camera module behind the display surface and allowing it to pop up when needed. This dimensional transition from 2D bezel integration to 3D pop-up mechanism resolves the contradiction between bezel size and camera function.
2Area of stationary object
If the camera module is placed behind the screen, then the edge-to-edge display is achieved, but a mechanism is needed to enable camera functionality
Solution Approach 1:
The camera module is nested within the display assembly structure, with the accommodation frame integrated into the display housing. The elevating mechanism uses nested components including the accommodation frame, elevating frame, and guide portions that fit within each other, reducing overall complexity while enabling the pop-up function.
Solution Approach 2:
The elevating mechanism is segmented into distinct functional components: the accommodation frame for holding the camera, the elevating frame for movement, and the guide portions for directional control. This segmentation allows each component to be optimized independently and simplifies the overall design by distributing functionality across multiple simple parts rather than one complex mechanism.

If the accommodation frame is always in the inclined position, then the camera shooting function is optimized, but the camera cannot be hidden when not in use
Solution Approach 1:
The accommodation frame is designed to be rotatable between a first position (retracted behind the display) and a second position (inclined for shooting). This dynamic positioning allows the system to optimize for different states: hiding the camera when not in use to maintain edge-to-edge display appearance, and extending it when camera function is needed for reliable shooting.

AI summary
An elevating mechanism adapted to accommodate a function unit and including main frame, elevating frame, and accommodation frame. The main frame has first guide portion including straight portion and non-straight portion. The elevating frame is movably disposed on the main frame. The accommodation frame is pivotably connected to the elevating frame and has second guide portion slidably located at the first guide portion. When the accommodation frame is in non-inclined position, the second guide portion is located at the straight portion. When the accommodation frame is in inclined position, the second guide portion is located at the non-straight portion and the accommodation frame is inclined with respect to the main frame.
