Movable Camera Holder for Sliding Device Optical Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The structure of a camera module does not change with the structure of an electronic device, making it difficult to adjust focal distance or optical magnification, especially in slidable devices where the device size increases with housing movement.
Innovation Solution
An electronic device with a movable second housing, a flexible display, and a camera module where the second camera holder is movable along the optical axis with respect to the first camera holder, allowing the processor to adjust the lens modules to match the changing device structure and optical magnification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the electronic device increases in size with housing movement, then the display area is extended, but the camera module cannot utilize the additional space to adjust focal distance or optical magnification
Solution Approach 1:
The camera module is divided into two separate camera holders (first and second camera holders) that can move independently relative to each other. This segmentation allows each holder to be positioned at different locations along the optical axis, enabling the camera module to adapt to different device configurations and utilize available space effectively for focal distance and magnification adjustment.
Solution Approach 2:
The camera holders are designed to be movable along the optical axis rather than fixed. The second camera holder can move relative to the first camera holder, and both can be positioned at different locations depending on the device structure. This dynamic design enables the camera module to adapt its configuration when the electronic device changes size through housing movement.
2Device complexity
If the camera module structure remains fixed, then the device structure can be simplified, but it becomes difficult to change focal distance or optical magnification
Solution Approach 1:
The camera module employs movable camera holders that can be positioned at different locations along the optical axis. The second camera holder moves relative to the first camera holder, and both holders can be independently positioned. This dynamic structure enables focal distance and optical magnification adjustment without requiring a completely complex reconfiguration system.
Solution Approach 2:
The movable camera holder design serves multiple functions: it enables focal distance adjustment, optical magnification change, and adaptation to different device configurations. This universal design approach allows a single structural mechanism to handle various adjustment requirements, reducing the need for separate dedicated mechanisms for each function.
3Volume of stationary object
If the lens cannot move due to limited space, then the camera module size can be reduced, but it becomes difficult to adjust optical magnification
Solution Approach 1:
The camera holders move along the optical axis (one-dimensional movement), which allows the lenses to change position and achieve optical magnification adjustment within a compact volume. By utilizing the optical axis dimension for movement, the design achieves magnification adjustment capability without requiring large lateral space or complex multi-dimensional mechanisms.
