Transparent Helmet Shell with Optical Coatings for Peripheral Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports helmets restrict the peripheral visual field, particularly in horizontal, vertical, and oblique areas, limiting the wearer's ability to detect potential impacts and increasing the risk of collisions.
Innovation Solution
A transparent, semi-transparent, or translucent helmet shell with optical layers that enhance light transmission for improved visibility while providing an anti-reflective effect internally and a desired appearance externally, using materials like polycarbonate and metalized coatings to increase horizontal, vertical, and oblique visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional opaque helmet shells are used, then protection and structural integrity are provided, but the wearer's peripheral visual field is restricted and collision detection ability is reduced
Solution Approach 1:
The helmet shell transitions from traditional opaque colors to transparent, semi-transparent, or translucent materials, fundamentally changing the optical properties to allow light transmission while maintaining structural protection. This enables the wearer to see through the helmet in all directions without compromising safety.
Solution Approach 2:
The invention uses composite material structures combining transparent polycarbonate shell material with integrated optical coatings (anti-reflective, scratch-resistant, UV-protective layers) to achieve both transparency for improved vision and protective functionality.
2Loss of information
If transparent helmet materials are used, then peripheral visual field is improved, but light reflection interferes with wearer visibility and external appearance is compromised
Solution Approach 1:
Optical coating layers serve as intermediary elements between the external environment and the wearer's eyes. These coatings (anti-reflective, scratch-resistant, UV-protective) modify light interaction with the transparent shell, reducing harmful reflections and maximizing useful light transmission while maintaining external aesthetics.
Solution Approach 2:
The invention modifies optical parameters of the helmet shell by applying specialized coatings that change reflectivity, transmissivity, and protective properties. Anti-reflective coatings reduce glare, UV coatings block harmful radiation, and scratch-resistant coatings maintain optical clarity over time.

AI summary
A sports helmet optimizes the full peripheral field of vision of its wearer. The optical properties of the entire protective shell will allow the transmission of light, while reflecting a colored appearance externally, and remaining antireflective from the eye of the wearer. Internal padding and face guard also enhance the transmission of light compared to existing designs. Helmets constructed in accordance with the invention are made with a transparent shell material, with one or more optical layers to achieve an anti-reflective view from the eye side of the helmet and an acceptable appearance on the external surface of the shell. Single or multiple metalized thin films may be used to create a one-way mirror effect. In other embodiments see-through graphics may be used with microdot patterns. In certain embodiments, multiple optical coatings may be used to achieve a desired combination of transparency and light-absorbing properties.
