Goggle Frame Perforation and Gasket for Moisture Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sport goggles and glasses often compromise user comfort due to inadequate sealing and moisture management, which can lead to fogging and reduced visibility.
Innovation Solution
The design incorporates a goggle frame with a perforated second frame surface that allows moisture to pass through, coupled with a gasket that conforms to the user's face and directs moisture away from the eyes, and a lens retainer that moves between positions to secure the lens effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If seals and gaskets are made to conform closely to the user's face to improve sealing, then sealing effectiveness is improved, but user comfort deteriorates due to excessive contact pressure
Solution Approach 1:
The goggle frame incorporates a compliant portion made of elastomeric material that selectively contacts specific areas of the user's face (nose, cheeks, forehead) to provide sealing while distributing contact pressure. This localized compliance approach maintains seal integrity without requiring the entire gasket to exert high pressure, thereby improving user comfort while preserving sealing effectiveness.
2Reliability
If a roll-off film system covers a larger lens area to improve effectiveness, then visibility maintenance is improved, but device complexity increases
Solution Approach 1:
The patent employs a thin film roll-off system that can be integrated into the goggle lens assembly. The film is conveyed across the lens surface and rolled off when contaminated, providing a simple yet effective mechanism to maintain visibility without requiring complex mechanical structures. The thin film nature allows it to conform to the lens curvature while providing adequate coverage area.
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 configuration enhances user comfort by effectively managing moisture, reducing fogging, and maintaining clear visibility during sports and activities.
Implementation Method 1
the perforation is configured to pass moisture from an one side of the second frame surface to an other side of the second frame surface
Implementation Method 2
a gasket coupled to the second frame surface and configured to conform to a portion of the user's face and configured to pass the moisture from the user's face to the second frame surface
