Rotatable Flip Cover Optical Filter for Mobile Camera Glare
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The quality of images captured by digital cameras in mobile devices is affected by various accessories, and there is a need for a solution that allows users to selectively enhance image quality by controlling light transmission and polarization.
Innovation Solution
A casing with a flip cover containing an optical filter, such as a polarization filter, that can be rotated and positioned in front of the camera, allowing users to control light transmission and reduce glare by aligning the filter with the camera aperture, and a window with integrated optical filters that transmits light to both the camera and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an optical filter is placed in front of the camera, then glare is reduced and image quality is improved, but light transmission is blocked and image brightness is reduced
Solution Approach 1:
The optical filter is integrated into a rotatable flip cover that can dynamically adjust its position. The flip cover can rotate between covering the camera (filter in front of lens) and uncovering the camera (filter away from lens), allowing dynamic control over when the filter is applied based on shooting conditions
Solution Approach 2:
The flip cover is divided into distinct functional zones: a first area with the optical filter for glare reduction, a second area that is transparent or translucent for normal shooting, and a third area for aesthetic design. This segmentation allows selective application of filtering functionality
2Adaptability or versatility
If a flip cover with optical filter is added to the mobile device, then image quality control is improved, but device complexity increases
Solution Approach 1:
The flip cover serves multiple functions: it contains the optical filter for glare reduction, acts as a protective cover for the camera, provides aesthetic design elements, and enables user control over filtering. The same component performs multiple roles rather than requiring separate dedicated parts
Solution Approach 2:
The optical filter is merged with the flip cover structure rather than being a separate accessory. The filter, cover, and decorative elements are combined into a single integrated component that attaches to the mobile device housing
3Object-affected harmful factors
If the flip cover blocks the camera aperture, then optical filter effectiveness is improved, but camera access is blocked
Solution Approach 1:
The flip cover is designed to be rotatable, allowing users to dynamically switch between having the filter in front of the camera (when glare reduction is needed) and having the filter away from the camera (when normal shooting is needed). This dynamic positioning resolves the conflict between filter effectiveness and camera accessibility
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances image quality by reducing glare and allowing users to adjust polarization settings, while also enabling the observation of the display when the flip cover is in the front position, thereby improving the overall imaging experience.
Implementation Method 1
The flip cover may comprise an optical filter located to enable image capturing by the camera through the optical filter
Implementation Method 2
