Integrated Optical Lens in Double-Pane Goggle Visor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ski goggles and helmet visors with double panes restrict peripheral vision and cause fogging issues, making it difficult for individuals with ametropia to wear optical glasses due to limited cavity size and protruding optical lenses that can graze against eyelashes.
Innovation Solution
Integrating an optical lens for correcting ametropia into the inner pane of a double-pane lens system, reducing light-refracting surfaces, allowing adjustable distance for comfortable wear, and using a detachable tongue and groove system for easy lens replacement, which enhances light transmission and prevents fogging and mechanical damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an optical lens is clamped into the space between the user's face and the lens of ski goggles using conventional inner clips, then optical correction for visual impairments is achieved, but the lens diameter is significantly smaller than conventional glasses, severely restricting peripheral vision
Solution Approach 1:
The patent merges the optical correction lens with the inner goggle lens into a single integrated unit. The corrective lens is positioned directly behind the inner lens without requiring a separate clamping mechanism, allowing the full diameter of the inner lens to be utilized and restoring peripheral vision while maintaining optical correction capability.
2Adaptability or versatility
If an optical lens is clamped into the space between the user's face and the lens of ski goggles, then optical correction is provided, but the protruding lens frequently fogs up and eyelashes rub against it
Solution Approach 1:
By integrating the optical lens with the inner lens, the patent eliminates the protruding structure that causes fogging and eyelash contact. The merged design maintains a smooth surface that prevents these harmful interactions while preserving the optical correction function.
Solution Approach 2:
The optical lens is nested within the inner lens structure, positioned directly behind it without protruding outward. This nesting arrangement allows the corrective lens to function while remaining flush with the goggle lens surface, preventing fogging and mechanical contact with eyelashes.
3Adaptability or versatility
If a multi-layered structure with outer lens, inner lens, and optical lens positioned between them is used, then optical correction is achieved, but the number of light-refracting surfaces increases to six, reducing light transmission and increasing vision stress
Solution Approach 1:
The patent combines the inner lens and optical lens into a single integrated unit, reducing the number of separate interfaces. This merging eliminates two additional refracting surfaces, allowing light to pass through with minimal refraction and energy loss, thereby improving light transmission efficiency and reducing vision stress.
Solution Approach 2:
The integrated inner lens-optical lens unit serves multiple functions simultaneously: it provides the goggle's primary optical properties (anti-fog, UV protection) and the corrective lens's refractive power in a single structure, eliminating the need for separate layers and reducing total refraction interfaces.
4Ease of manufacture
If the distance between the optical lens and the user's eye is not adjustable, then manufacturing is simplified, but adjustment difficulties arise when switching between glasses
Solution Approach 1:
The patent incorporates an adjustable mechanism that allows the distance between the optical lens and the user's eye to be modified. This dynamic adjustment capability enables users to adapt the goggle system to match their prescription lens specifications, facilitating easy switching between different glassware while maintaining manufacturing simplicity through a standardized adjustable interface.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design increases field of view, reduces vision stress, prevents eyelash contact, and maintains optical clarity by minimizing fogging and mechanical exposure, while ensuring high torsional rigidity and safety through improved peripheral vision and reduced frame impact.
Implementation Method 1
at least one optical lens for correcting visual impairments is integrated into the inner pane... the transmission of light is influenced by only four refractive surfaces instead of six
Implementation Method 2
the optical lens can be anti-reflective, thus increasing light transmission and reducing distracting reflections
Implementation Method 3
the air cushion trapped in the space between the inner and outer visors also helps prevent fogging
