Cap Light Penetrating Member for Night Visibility and Eye Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional LED hats emit strong light that can hurt eyes and disrupt the exterior design, while also increasing manufacturing costs due to the need for multiple light sources to produce various colors.
Innovation Solution
A cap with a light emitting device that incorporates a light penetrating member made of opaque silicone with a design patch or mark, housing a light emitting module inside a pocket portion to prevent direct eye exposure and allow multiple color emission with single-colored LEDs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a traditional LED hat emits strong light forward, then visibility at night is improved, but it can hurt people's eyes around the wearer
Solution Approach 1:
The patent introduces a light diffusing member as an intermediary between the LED light source and the external environment. This member scatters the concentrated LED light into a wider, softer illumination pattern that maintains visibility benefits while eliminating the harmful concentrated beam effect on bystanders' eyes
Solution Approach 2:
The patent applies different optical properties to different regions of the light emitting assembly. The light diffusing member creates a gradient of light intensity distribution, with softer, dispersed light in directions where bystanders might be positioned, while maintaining adequate illumination forward
2Illumination intensity
If the light emitting part is exposed to outside the hat, then light emission function is achieved, but it disrupts exterior design of the hat
Solution Approach 1:
The patent nests the light emitting components (LED module and light diffusing member) within a recessed cavity or housing structure on the hat's exterior. This allows the functional elements to be contained within the hat's overall form, maintaining a clean, uninterrupted exterior design while preserving full light emission capability
Solution Approach 2:
The patent employs a flexible or translucent cover layer that can be integrated into the hat's exterior material. This thin film allows light to pass through while maintaining the continuity of the hat's outer surface, preventing disruption to the exterior design aesthetic
3Adaptability or versatility
If multiple light emitting means are used to emit various colored lights, then color variety is improved, but manufacturing costs increase
Solution Approach 1:
The patent utilizes a single white or blue LED light source combined with a light diffusing member that incorporates color-changing materials or structures. These materials can alter the perceived color of the emitted light through optical effects, filters, or fluorescent compounds, achieving multiple color outputs from one LED type and reducing component count and manufacturing complexity
Solution Approach 2:
The patent designs a universal light emitting assembly where a single LED module can produce multiple color effects through the optical properties of the light diffusing member. This multi-functional approach allows one component to replace what would traditionally require multiple separate colored LEDs, simplifying the manufacturing process
