Asymmetrical Swimming Goggle Seal for Comfort and Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swimming goggles with J-shaped protection pads fail to perfectly match the asymmetrical contours of wearers' eye sockets, leading to uncomfortable contact, pressure stress, and water leakage, and are not adaptable to varying face and nose bridge sizes.
Innovation Solution
The design incorporates a hard combining frame with soft frames and a thermoplastic rubber connection element, featuring a flexible edge and convex portions to accommodate different contours, and a flange rib for impact buffering, ensuring comfortable and watertight engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a J-shaped protection pad with unitary arc surface is used, then the structure is simple and easy to manufacture, but it fails to match the asymmetrical contour of the wearer's eye socket, causing water leakage
Solution Approach 1:
The protection pad is divided into an upper half part and a lower half part with different heights, allowing each part to match different regions of the asymmetrical eye socket contour. This segmentation enables the pad to conform to the wearer's face shape while maintaining manufacturing simplicity through modular design.
Solution Approach 2:
The protection pad transitions from a symmetrical unitary arc surface to an asymmetrical design where the upper half part has a different height than the lower half part. This asymmetry allows the pad to match the asymmetrical contour of the eye socket, preventing water leakage while maintaining comfort.
2Reliability
If a stronger pull force is applied on the head strap to compensate for the poor fit, then water leakage may be prevented, but it causes uncomfortable contact and panda eyes on the wearer's face
Solution Approach 1:
The protection pad applies different pressures to different regions of the eye socket through its asymmetrical design. The upper and lower half parts have different heights to match the local contours, distributing the adsorptive force evenly and eliminating the need for excessive pull force on the head strap.
3Ease of manufacture
If the protection pad is designed with same heights in upper and lower half parts, then the structure is simple, but it fails to meet the needs of wearers with different face sizes and contours
Solution Approach 1:
The protection pad design changes the height parameter differently for the upper and lower half parts. By adjusting these dimensions, the pad can accommodate various face sizes and contours while maintaining a relatively simple manufacturing process through standardized production methods.
4Stability of the object's composition
If a hard material connection element is used to interconnect lens frames, then the structure is rigid and stable, but it lacks flexibility for wearers with different nose bridge contours
Solution Approach 1:
The connection element transitions from a completely rigid hard material structure to a design that incorporates flexible sections. This allows the connection element to dynamically adapt to different nose bridge contours while maintaining overall structural stability through its hybrid construction.
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
The solution provides a comfortable, watertight seal for various face and nose bridge contours without pressure stress, enhancing wearing comfort and preventing water leakage.
Implementation Method 1
engaged to the wearer's face around the eye socket by means of an adsorptive force produced when the J-shaped protection pad is compressed and deformed in wearing
Implementation Method 2
the face contact portion is disposed with a flange rib with respect to an edge of the lens, so as to provide a buffer against an impact caused when being compressed and deformed

AI summary
Swimming goggles of the present invention comprise a hard combining frame, a left soft frame, and a right soft frame. The hard combining frame is composed of a first embedding frame and a second embedding frame, each having an embedding hole. The left and right soft frames are respectively assembled with the embedding holes. Each of the left and right soft frames is composed of a frame portion and a face contact portion. The frame portion assembled with each of the left and right soft frames receives a lens, characterized in that: the face contact portion is disposed with a flange rib with respect to an edge of the lens, to provide the face contact portion with a buffer against an impact caused when being compressed and deformed in wearing, and to provide a desired engagement without pressure stress and water leakage to ensure a wearing comfort.
