External Lens Mounting for Mobile Terminal Camera
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing built-in camera modules in mobile terminals are limited by the overall size of the device, restricting improvements in camera function and imaging quality, and a thicker camera module can compromise aesthetics, usability, and internal space for other components.
Innovation Solution
A mobile terminal design featuring a device housing with a light-permeable portion and an external connection portion, allowing an external lens assembly to be detachably mounted, while an image sensor assembly is housed inside, enabling improved imaging capabilities without occupying internal space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the camera module is made thicker to improve imaging quality, then the imaging quality improves, but the overall thickness of the mobile terminal increases and aesthetics deteriorate
Solution Approach 1:
The lens assembly is extracted from the internal structure of the mobile terminal and positioned externally on the back cover. This allows the image sensor assembly to remain thin within the terminal while the lens can have optimal thickness for imaging quality without increasing the terminal's overall thickness.
Solution Approach 2:
The camera module transitions from a three-dimensional internal structure to a two-dimensional surface mounting configuration. The lens assembly is mounted on the external surface of the back cover, separating the optical path from the terminal's thickness dimension.
2Manufacturing precision
If the camera module is made thicker to improve imaging quality, then the imaging quality improves, but the layout area of the main board and installation spaces for other components are reduced
Solution Approach 1:
The lens assembly is extracted from the internal space and positioned externally, freeing up the internal layout area for main board and other components while maintaining optimal imaging quality through the external lens configuration.
3Adaptability or versatility
If an external lens assembly is detachably mounted, then the adaptability and imaging functionality improve, but the device complexity increases
Solution Approach 1:
The external lens assembly is designed with a universal mounting structure that can accommodate different lens types (telephoto, wide-angle, macro) while using the same mounting interface on the back cover, allowing one mounting structure to serve multiple imaging functions.
