Rotating Pop-Up Camera Mechanism for Seamless Mobile Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals with pop-up cameras require a camera hole in the front face for photography, limiting the implementation of a seamless front face display and restricting the camera's rotational functionality.
Innovation Solution
A mobile terminal design featuring a pop-up camera that is rotatably driven through an opening in the housing, using a driving unit with a shaft member and actuator, connected via a flexible printed circuit board and a connection member with grooves and protrusions, allowing the camera to rotate and retract, thus eliminating the need for a camera hole on the front face.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera hole is provided in the front face display for photography, then the camera can be disposed on the front face, but the display cannot be implemented seamlessly and the design aesthetics are compromised
Solution Approach 1:
The camera module is extracted from the front face display and disposed in the side face, eliminating the need for a camera hole in the display. The camera module includes a camera unit and a driving unit that moves the camera module between a retracted state (inside the housing) and a protruding state (outside the housing), allowing the display to be implemented seamlessly without any holes or openings.
Solution Approach 2:
The camera module is moved from a two-dimensional plane (front face display) to a three-dimensional space (side face housing), protruding from the side face of the mobile terminal. This dimensional change allows the camera to be accessible for photography while maintaining an uninterrupted front face display surface.
2Adaptability or versatility
If the camera is fixed in position, then the structure is simple, but the camera cannot rotate to capture images from different angles
Solution Approach 1:
The camera module is designed with rotational capability around its longitudinal axis, transforming from a static fixed structure to a dynamic rotatable structure. The driving unit enables the camera module to rotate while protruding from the side face, allowing image capture from multiple angles without requiring multiple fixed cameras.
Solution Approach 2:
The single camera module serves multiple functions by combining linear movement (retracting and protruding) with rotational movement. This multi-functionality allows the camera to capture images from different positions and angles, replacing what would traditionally require multiple fixed cameras positioned at different locations.
3Adaptability or versatility
If the camera module is made rotatable around the shaft member, then the camera can capture images from different angles, but the flexible printed circuit board connection becomes complex
Solution Approach 1:
A flexible printed circuit board is used to connect the camera module to the main circuit board, allowing the camera module to rotate around the shaft member. The flexible nature of this circuit board accommodates the rotational movement without requiring complex rigid connections or multiple separate wiring harnesses, simplifying the overall connection structure despite the rotational capability.
