Flash Insert For Mobile Phone Case Color Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile device cases with non-neutral colors interfere with the flash light of cameras, causing erroneous color and image distortions in photos due to light reflection, which affects both the main and secondary cones of light.
Innovation Solution
Incorporating a neutral-colored insert or coating into the case, which can be absorptive or reflective, to minimize light reflection and maintain the desired color and reflectivity of the case while preventing color impartation on the subject.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a non-neutral colored case is used for protection and styling, then the case provides cosmetic appeal and protection, but the case imparts erroneous color to the flash light and causes image distortion
Solution Approach 1:
The case is divided into two functional parts: an outer colored case for protection and styling, and an inner neutral-colored insert (gray or black) positioned around the flash and camera aperture. This segmentation allows each part to fulfill its specific function without interfering with the other.
Solution Approach 2:
Different parts of the case have different color properties: the outer case can be any color for aesthetic purposes, while the inner insert surrounding the flash aperture is specifically made neutral (gray or black) to prevent color interference with the flash light. This local differentiation of color properties solves the contradiction.
2Illumination intensity
If a substantial cut out is made in the case for the camera and flash, then the flash has better light access, but the case still interferes with the secondary cone of light causing color reflection
Solution Approach 1:
A neutral-colored insert acts as an intermediary element between the flash light and the colored outer case. This insert absorbs or neutrally reflects the secondary cone of light, preventing the colored case material from reflecting erroneous colors back into the light path.
Solution Approach 2:
The potentially harmful reflection from the colored case is converted into a beneficial neutral reflection or absorption by the inner insert. The insert's neutral color ensures that any reflected light remains color-neutral, turning the problematic reflection into a non-interfering element.
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
Significantly reduces the impact of case color on the flash light, ensuring accurate color representation in photos by controlling light reflection and absorption, allowing the case to be any color while maintaining image quality.
Implementation Method 1
Incorporating a neutral-colored insert or coating into the case, which can be absorptive or reflective, to minimize light reflection
Implementation Method 2
the case often interferes with the secondary cone of light... the reflected light that bounces off the case and reaches the subject

AI summary
A case, for an electronic device such as a mobile phone, containing an insert located near a camera, still image recorder, or video recorder and a flash of the device is disclosed. The placement, material, color, and properties of the insert helps reduce and/or eliminate problems associated with the case affecting the resultant flash/light from the camera causing and adding erroneous colors, effects, and information on the resulting pictures, images, sensors, or videos.
