Helmet Illuminable Strips for Low-Light Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional helmets lack effective means to increase visibility in low-light conditions without relying on external light sources, as reflective strips require external illumination to function.
Innovation Solution
Integration of illuminable straps with embedded light sources, such as LEDs, within the helmet's energy-management liner, which illuminate outward-facing surfaces to enhance visibility and attractiveness, even in the absence of external light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If reflective strips are used to increase helmet visibility, then visibility is improved under external illumination, but visibility fails in the absence of external light sources
Solution Approach 1:
The patent combines light sources with light-guiding elements within the helmet structure. The light sources (e.g., LEDs) are integrated into the helmet body, and light guides (such as translucent or transparent sections of the shell) channel and distribute the light to create illuminated patterns that enhance visibility from multiple angles, resolving the limitation of reflective strips that only work with external light.
Solution Approach 2:
The helmet becomes self-illuminating through integrated light sources that generate their own light without requiring external illumination. The light sources are powered by internal power supplies (such as batteries) and controlled by control circuits, enabling the helmet to actively emit light and patterns to enhance visibility in dark environments independently.
2Illumination intensity
If light sources are integrated into the helmet, then visibility in dark environments is enhanced, but device complexity increases
Solution Approach 1:
The helmet structure is designed to serve multiple functions: the light sources not only illuminate for visibility but can also display patterns, signals, or information. The control circuitry enables various operational modes (steady illumination, flashing patterns, color changes) from a single integrated system, reducing the need for separate specialized components for different visibility needs.
Solution Approach 2:
The patent utilizes translucent or transparent sections of the helmet shell as light guides. These thin film or shell sections are integrated directly into the helmet structure, eliminating the need for separate light guide components. The flexible nature of these translucent sections allows them to conform to the helmet's shape while effectively channeling and distributing light.

Function Achieved in This Case
The solution ensures the wearer's visibility is enhanced, particularly in dark environments, without the need for external light sources, thereby reducing the likelihood of accidents by making the wearer more conspicuous to others.

AI summary
A helmet including fit system straps with illuminable strips on them or woven into them and one or more light sources positioned adjacent the tops of the fit system straps on the helmet body to emit light toward the illuminable strips. The light sources may be connected directly to the illuminable strips to emit light into an end of the illuminable strips. The light sources may emit light from or near a lower surface of the helmet body toward the illuminable strips.
