Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prolonged exposure to blue light from electronic devices can cause macular degeneration and vision loss, and existing solutions like blue-light blocking glasses are inconvenient and can distort color perception, especially for those who already wear glasses.
Innovation Solution
A yellow backlight system that emits yellow light to neutralize and reduce the intensity of blue light emitted by display devices, using methods like reflection, refraction, or direct illumination, eliminating the need for additional glasses and preventing color misjudgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If blue-light blocking glasses are used to reduce blue light intensity, then the impact on human visual cells is reduced, but color perception is distorted and users must replace existing glasses
Solution Approach 1:
A yellow light source is introduced as an intermediary element between the display device and the user's eyes. The yellow light neutralizes the blue light from the screen, reducing its harmful effects without requiring the user to wear blue-light blocking glasses, thereby maintaining color perception accuracy and convenience
Solution Approach 2:
The invention converts the harmful blue light into a beneficial effect by using yellow light to neutralize it. The yellow light from the light source counteracts the blue light from the display, transforming the potential harm into a protective effect that reduces visual cell damage while maintaining normal color perception
2Object-affected harmful factors
If blue-light blocking lenses are used to filter blue light, then blue light intensity is reduced, but users incur additional costs and must replace existing glasses
Solution Approach 1:
A yellow light source serves as an intermediary that reduces blue light intensity in the environment without requiring physical blue-light blocking lenses. This eliminates the need for users to purchase and replace glasses, thereby avoiding additional costs while still achieving blue light reduction
Solution Approach 2:
The system provides blue light protection through an ambient light source that automatically neutralizes blue light without requiring user action to wear or adjust special glasses. The protection is self-service in nature, continuously operating in the background without additional user expense or effort
