Mobile Terminal Camera Cover Light-Transmitting Region Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals have a simple and uniform transparent region for the camera cover sheet, which does not efficiently utilize space and can lead to a larger size for the decorative ring and battery cover, affecting aesthetics and structural strength.
Innovation Solution
A mobile terminal design featuring a light-transmitting region with edge contour lines comprising alternating straight and arc segments, allowing for a reduced size while maintaining the camera's field of view, and integrating this design into the battery cover and decorative ring to enhance aesthetics and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the transparent region of the cover sheet is designed as a simple square or round shape, then the structure is simple and easy to manufacture, but the area of the light-transmitting region is larger, causing the decorative ring and battery cover to be larger and affecting aesthetics and structural strength
Solution Approach 1:
The edge contour lines of the light-transmitting region are segmented into alternating straight line segments and arc line segments, creating a composite shape that combines simplicity with space efficiency. This segmentation allows the design to maintain ease of manufacture while reducing the overall area compared to traditional simple geometric shapes.
Solution Approach 2:
The light-transmitting region adopts an asymmetric composite shape with alternating straight and curved edges, breaking away from traditional symmetric square or round designs. This asymmetric design optimizes the use of space, reducing the area occupied by the light-transmitting region while ensuring the camera's field of view requirements are met.
2Area of stationary object
If the light-transmitting region is reduced in area, then the decorative ring and battery cover can be smaller improving aesthetics and structural strength, but it may affect the camera's ability to capture all ambient light
Solution Approach 1:
The edge contour lines are designed with alternating straight and arc segments that are strategically positioned to align with the camera's field of view. This local optimization ensures that light within the required field of view can still enter the camera effectively, while reducing light transmission in areas that do not contribute to the camera's function, thus maintaining reliability while reducing area.
Solution Approach 2:
The design transitions from considering only the area of the light-transmitting region to optimizing the shape and distribution of light transmission. By using alternating straight and arc line segments, the design creates a more efficient two-dimensional arrangement that reduces total area while maintaining the necessary light capture capability through strategic positioning of transparent and light-shielding regions.
3Illumination intensity
If the first straight line segments are entirely located in the circular viewing angle, then maximum light transmission is achieved, but the area of the light-transmitting region increases
Solution Approach 1:
The first straight line segments are designed to be partially or entirely located in the circular viewing angle, rather than completely. This partial action approach provides an optimal balance: enough straight line segments are positioned within the viewing angle to ensure sufficient light transmission for the camera's field of view, while avoiding the excessive area that would result from extending all straight segments entirely within the circular viewing angle.
