Helmet Light Accessory With Fiber Optic Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional safety helmets and hard hats lack visibility in low light conditions, relying on external light sources for reflection, which can be inadequate for worker safety, especially in distinguishing different colored helmets at night or in dark environments.
Innovation Solution
A 360-degree visible light accessory for safety helmets, featuring a side glow fiber optic cable with LEDs, mounted to a plastic or high-heat-resistant base plate, allowing for easy attachment and detachment without tools, providing continuous or pulsed color options for enhanced visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional safety helmets are used without integrated light sources, then the structural integrity and simplicity of the helmet is maintained, but worker visibility in low light conditions deteriorates
Solution Approach 1:
The light accessory is nested within a mounting ring that fits over the crown portion of the helmet, creating a compact integrated assembly that maintains helmet simplicity while adding visibility functionality
Solution Approach 2:
The mounting ring acts as an intermediary component between the light source and the helmet, allowing the light accessory to be attached without modifying the helmet's structural integrity while providing the desired illumination function
2Illumination intensity
If high visibility safety vests with reflective tape are used, then worker visibility is improved during daytime, but the effectiveness deteriorates at nighttime without external light sources
Solution Approach 1:
The safety helmet ensemble generates its own light through integrated LEDs and fiber optic cables, making the visibility system self-sufficient and independent of external light sources, ensuring consistent visibility day and night
Solution Approach 2:
The fiber optic cable system transmits light to create visible illumination around the helmet, changing the optical properties of the helmet ensemble to actively emit light rather than merely reflect it, ensuring reliable visibility in all lighting conditions
3Loss of information
If multiple colored hard hats are used for different roles, then worker identification is improved during daytime, but color differentiation deteriorates in low light conditions
Solution Approach 1:
The system uses colored LEDs that can be programmed to emit different colors corresponding to different worker roles, and the fiber optic cable transmits these colors around the helmet, maintaining color identification functionality in low light conditions
Solution Approach 2:
The LEDs can operate in periodic or pulsed modes with different colors, creating temporal patterns that enhance color differentiation and role identification even in dark environments where static color visibility would be poor
4Stability of the object's composition
If permanent mounting methods are used to attach light sources to helmets, then the light accessory stability is improved, but the helmet structural integrity deteriorates
Solution Approach 1:
The light accessory system is segmented into separate components (light source, fiber optic cable, mounting ring) that can be independently attached and removed, providing stability during use while avoiding permanent modifications to the helmet structure
Solution Approach 2:
The mounting system provides dynamic attachment that adapts to different helmet types and styles, allowing the light accessory to be securely fixed during operation while maintaining the option for easy removal and preserving helmet integrity

AI summary
A light accessory for a safety helmet enhances visibility of the safety helmet when worn. The light accessory includes a mounting ring and a light source assembly. The mounting ring includes a central ring opening. The central ring opening is configured to receive a crown portion of a safety helmet. The light source assembly includes at least one circumferential light source and a control unit. The light source is positioned in radial outer adjacency to the central ring opening so as to extend about at least a circumferential portion of the crown portion. The light source is configured to emit light at least radially outwardly relative to the crown portion. The control unit includes a power source. The light source is in electrical communication with the power source enabling the user to selectively power on and off the light source for enhancing visibility of the safety helmet ensemble.
