Contoured Helmet Lighting System Mounting Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a helmet-mounted lighting system that can be securely attached to protective headwear, serving as a safety device by providing hands-free illumination and acting as a visual indicator of the wearer's presence and location, while being durable and waterproof.
Innovation Solution
A helmet-mounted lighting system comprising a battery, a mounting plate, a printed circuit board (PCB) with a light emitting diode (LED), a capacitor, and a switch, where the mounting plate is contoured to fit curved surfaces, and the cover is transparent or translucent to allow visibility of the LED, with programmable logic to control LED operation and emission of various light colors or infrared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a light source is affixed to a helmet for hands-free lighting, then illumination is provided, but secure mounting on curved helmet surfaces is difficult
Solution Approach 1:
The mounting plate is contoured with a curved surface that matches the curvature of helmet surfaces, allowing the lighting system to securely attach to rounded protective headwear. This curvature adaptation resolves the mounting difficulty on non-flat surfaces.
2Strength
If the cover is made opaque for protection, then durability is improved, but LED visibility is reduced
Solution Approach 1:
The cover is designed with different optical properties in different regions: it is translucent or transparent in areas where LED visibility is needed, and can be more opaque in other areas for protection. This localized quality differentiation allows the cover to simultaneously provide protection and visibility.
3Reliability
If the lighting system is made waterproof for durability, then reliability in various conditions is improved, but device complexity increases
Solution Approach 1:
The cover acts as a flexible or semi-rigid protective shell that encapsulates the electronic components, providing waterproof protection through its enclosing structure. This shell approach simplifies waterproofing compared to complex sealing mechanisms while maintaining durability.

AI summary
Implementations of a helmet mounted lighting system are provided. In some implementations, the lighting system may be mounted to a helmet, hard hat, and/or other type of protective headwear. In some implementations, the lighting system acts as a safety device when mounted to a protective headwear by providing illumination which serves as a visual indicator of the wearer's presence and/or location. In some implementations, the lighting system may comprise a mounting plate, a cover, a battery, and a printed circuit board (PCB). In some implementations, the PCB may comprise a logic board, one light emitting diode (LED), a capacitor, and/or a switch. Together, the mounting plate and cover form a housing that encases the battery and the PCB. In some implementations, the bottom side of the mounting plate may be contoured for attachment to the curved exterior surface of a protective headwear.
