Colored Film for Mobile Flash Light Color Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile devices are limited to emitting only white light, which restricts their ability to participate in multi-colored light shows and provide identification in low light conditions.
Innovation Solution
The solution involves applying a colored film or using a color wheel with filters to change the color of the light emitted by a mobile device's flash, or altering the light frequency using software, allowing for selective color adjustment of the flash light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mobile devices emit only white light, then the device structure remains simple, but the ability to participate in multi-colored light shows and provide identification in low light conditions is limited
Solution Approach 1:
The patent introduces colored films as intermediary elements that are applied to the mobile device flash. These films act as mediators between the white light source and the desired colored output, allowing color variation without modifying the flash LED itself. Users can attach different colored films to achieve different colors for light shows and identification purposes.
Solution Approach 2:
The patent segments the color generation function from the light source by using separate colored films for each color. Instead of requiring multiple LEDs or complex color mixing mechanisms, the solution divides the color production into discrete, interchangeable film components that can be individually selected and applied.
2Adaptability or versatility
If colored films or filters are added to mobile devices, then multi-colored light shows and identification capability are enabled, but the device complexity increases
Solution Approach 1:
The patent employs inexpensive, easily replaceable colored films that can be quickly attached and removed. These films are designed as simple, low-cost components that users can swap out to change colors, avoiding the need for expensive, complex, or permanent modifications to the mobile device. The films serve as temporary, disposable solutions for color variation.
Solution Approach 2:
The colored films serve multiple functions: they enable participation in multi-colored light shows, provide identification capability in low light conditions, and can be used with any standard mobile device flash. This universal application across different devices and use cases maximizes the versatility of the simple film attachment solution.
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
Enables crowd participation in multi-colored light shows and provides identification at a distance in low light conditions by allowing users to coordinate and change the color of their mobile device flash lights.
Implementation Method 1
applying a colored film or using a color wheel with filters to change the color of the light emitted by a mobile device's flash
Implementation Method 2
software changing the frequency of the light emitted from the LED flash
Data Source
AI summary
One or more colored films selectively change the color of the displayed light from one or more mobile devices to enable crowd participation is a multi-colored light show at public gatherings. The ability to change the color of a mobile device flash may also be useful for providing identification at a distance in low light conditions.
