Integrated Goggle Barrier Seal Without Separate Gaskets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional goggles require a separately formed gasket for sealing, which complicates manufacturing, increases costs, and results in waste due to the shape of the gasket.
Innovation Solution
A goggle design with an integrally formed chassis and barrier that simplifies manufacturing by eliminating the need for a separate gasket, forming a seal between the lens and chassis to prevent moisture and particulate matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separately formed gasket is used for sealing, then the seal function is achieved, but manufacturing complexity increases and costs increase
Solution Approach 1:
The barrier element is integrated directly into the chassis structure, merging two separate components (chassis and gasket) into a single unified component. This eliminates the need for separate gasket formation and assembly operations, reducing manufacturing complexity while maintaining the seal function between the lens and chassis.
Solution Approach 2:
The chassis structure serves multiple functions simultaneously: it provides the structural framework of the goggle and incorporates the barrier element to create the sealing function. This multi-functionality reduces the number of separate components needed, simplifying manufacturing while achieving both structural support and sealing objectives.
2Reliability
If a separately formed gasket is used for sealing, then the seal function is achieved, but manufacturing costs increase
Solution Approach 1:
By combining the chassis and barrier element into a single molded component, the patent eliminates the need for separate gasket production and assembly operations. This reduces manufacturing steps, material waste, and assembly costs, thereby lowering overall manufacturing cost while maintaining effective sealing.
Solution Approach 2:
The patent extracts the sealing function from a separate gasket component and integrates it directly into the chassis structure. This extraction and integration eliminates the need for separate gasket handling, storage, and assembly processes, reducing costs associated with managing separate components.
3Reliability
If a separately formed gasket is used for sealing, then the seal function is achieved, but material waste increases
Solution Approach 1:
The integration of the barrier element into the chassis eliminates the need for separate gasket material that would otherwise be produced, stored, and disposed of. This reduces material waste by eliminating the entire gasket component lifecycle while maintaining the necessary sealing function.
Solution Approach 2:
By eliminating the separate gasket component, the patent eliminates the waste associated with gasket production, defects, and disposal. The unified chassis structure uses material more efficiently by eliminating redundant components, thereby reducing overall material consumption and waste.

AI summary
Eyewear, such as a goggle, includes a movable unitary lens and a chassis. The movable unitary lens includes an interior surface. The chassis includes a body that defines a central opening, and the body is configured to be worn on the face of a wearer. The chassis further includes a barrier that is integrally formed with the body, and the barrier includes an exterior surface that contacts the interior surface of the lens along a perimeter of the lens so as to form a seal with the lens.
