Fuzzy Under-Eye Strip Reducing Low-Angle Glare
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing under-eye strips fail to effectively reduce low-angle reflected light, which can enter the eye and affect athletes' performance, as they typically have smooth, planar surfaces that do not scatter or absorb reflected light effectively.
Innovation Solution
An under-eye strip with a fuzzy surface, made from materials like artificial suede, which scatters and absorbs low-angle reflected light by creating an irregular surface with air-filled voids between fibers, reducing the amount of light that enters the eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a smooth, planar surface is used for the under-eye strip, then the strip is easy to manufacture and apply, but it reflects low-angle light effectively, allowing glare to enter the eye
Solution Approach 1:
The patent applies a fuzzy surface material with air-filled voids between fibers, creating a porous structure that traps and absorbs low-angle reflected light. This porous configuration prevents light from reflecting off the surface and entering the eye, while the material itself remains manufacturable through conventional processes.
Solution Approach 2:
The patent changes the surface parameter from smooth and planar to fuzzy and irregular. This parameter change in surface topology transforms the light interaction from specular reflection to diffuse absorption, effectively reducing glare while maintaining manufacturing feasibility through materials like artificial suede.
2Object-affected harmful factors
If a fuzzy surface is used for the under-eye strip, then low-angle light reflection is reduced, but the surface becomes more complex to manufacture
Solution Approach 1:
The fuzzy surface with air-filled voids creates a porous structure that effectively traps low-angle reflected light through multiple internal reflections and absorption events. The porosity parameter is optimized to maximize light trapping while maintaining a simple overall device structure that is easy to manufacture.
Solution Approach 2:
The patent employs inexpensive fuzzy materials such as artificial suede that can be easily manufactured and applied as disposable under-eye strips. This approach reduces the need for complex manufacturing processes while achieving effective glare reduction, making the solution economically viable.
3Object-affected harmful factors
If a fuzzy surface is used for the under-eye strip, then light scattering and absorption is improved, but the material selection and manufacturing process become more difficult
Solution Approach 1:
The patent utilizes porous fuzzy materials with air-filled voids that naturally scatter and absorb light. Common materials like artificial suede are identified as suitable candidates, simplifying material selection while achieving superior light absorption compared to smooth surfaces.
Solution Approach 2:
The patent changes the surface parameter from smooth to fuzzy, which fundamentally alters light interaction. This parameter change enables the use of commercially available fuzzy materials, expanding material options while improving light absorption performance without requiring complex manufacturing processes.
