Goggle Coupling Arrangement for Compression Sealing and Quick Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing goggles face challenges in maintaining a sealing engagement with the face to prevent fluid infiltration due to unwanted expansion forces from head movements, and require dedicated storage space for different types, complicating quick transitions between goggle types.
Innovation Solution
A coupling arrangement with a body member, compression inducing elements, and anchoring elements that apply clamping forces to maintain sealing engagement and resist expansion, allowing easy detachment and replacement of goggles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If goggles are connected peripherally to the frame by adhesion or welding, then the goggles are secured to the frame, but stress develops due to head movements causing microscopic or larger openings that compromise the protective sealing
Solution Approach 1:
The coupling arrangement divides the connection system into distinct functional elements: a body member with a central opening, a peripheral element with a continuous channel, and detachable goggle portions. This segmentation allows each component to perform its specific function - the body member provides structural support, the peripheral element creates a sealing interface, and the goggle portions can be independently replaced while maintaining seal integrity through the anchoring and compression mechanism.
Solution Approach 2:
The anchoring elements are pre-positioned on the goggle portions and the compression inducing elements are pre-installed on the body member. When the goggle portions are attached, the compression inducing elements automatically engage with the anchoring elements, pre-applied clamping forces to ensure immediate sealing engagement without requiring additional adjustment or tightening steps during use.
2Ease of operation
If goggles are configured with non-uniform peripheral shape to accommodate the nose bridge, then the goggles fit the facial structure, but a securing element cannot be readily connected to the entire periphery to apply radially inward force
Solution Approach 1:
The peripheral element features a continuous channel with varying cross-sectional dimensions that precisely match the non-uniform shape of the goggle peripheral edge at different locations. The channel provides localized sealing engagement - wider sections accommodate the temples and bridge areas while narrower sections fit the lens perimeters, allowing the securing element to effectively engage the entire periphery despite the non-uniform shape.
3Ease of operation
If multiple types of goggles are stored separately to ensure accessibility, then each goggle type is readily available, but sufficient storage space is required
Solution Approach 1:
The body member with its central opening and continuous channel is designed as a universal mounting structure that can accommodate multiple types of goggle portions with different lens configurations, sizes, and protective features. Different goggle portions can be attached to the same body member by engaging their anchoring elements with the compression inducing elements, eliminating the need for separate dedicated frames for each goggle type and significantly reducing storage space requirements.

AI summary
A coupling arrangement for goggles, comprising a body member having a central opening and bounded by a peripheral element with a continuous channel, monolithic goggles having a peripheral edge shaped as the peripheral element and is receivable in the channel to occlude the central opening, at least one compression element interacting with the peripheral element to urge the peripheral edge of the goggles in engagement with a surface of the channel, and at least one anchoring element protruding from the goggles and coupled with the at least one compression element that applies a clamping force onto the at least one compression element, wherein the applied clamping force is transmitted along a corresponding region of the peripheral element to resist movement of the goggles therein and to prevent infiltration of a fluid across the peripheral edge of the goggles towards the face of a wearer of the goggles.
