Water Goggles Elastic Ring Segmentation for Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water goggles often experience water leakage due to the elastic waterproof ring detaching from the eye contour during swimming or diving, leading to poor waterproofing performance.
Innovation Solution
The design includes a rim with a sealed lens, an elastic waterproofing ring, and a headband connected to both ends, featuring reinforcing ribs on the contact parts to distribute pulling forces evenly, ensuring the ring remains securely fitted to the eyes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the elastic waterproof ring is designed to be flexible for comfortable wear, then the comfort when wearing is improved, but the waterproofing reliability deteriorates because the ring may detach from the eye contour during swimming or diving
Solution Approach 1:
The elastic waterproof ring is divided into multiple contact parts (first contact part, second contact part, third contact part) that can independently contact different regions of the eye contour. This segmentation allows each part to maintain secure contact while the overall ring remains flexible for comfortable wear, preventing detachment during water activities.
Solution Approach 2:
Different regions of the elastic waterproof ring are designed with different contact characteristics. The first contact part contacts the outer contour of the orbit, the second contact part contacts the inner contour, and the third contact part contacts the bridge of the nose. Each region has optimized local properties to ensure secure contact while maintaining overall flexibility and comfort.
2Reliability
If the elastic waterproof ring contacts the eye contour at multiple points to prevent water leakage, then the waterproofing effect is improved, but the device complexity increases due to the need for multiple contact parts and connection structures
Solution Approach 1:
The first contact part, second contact part, and third contact part are merged into a single elastic waterproof ring structure that is elastically connected. This integration allows multiple contact points to work together as one unified component, achieving reliable waterproofing while avoiding the complexity of separate detachable parts.
Solution Approach 2:
The elastic waterproof ring serves multiple functions simultaneously: it provides comfort through flexible wear, ensures waterproofing through multi-point contact, and maintains structural integrity through the elastic connection of contact parts. The single ring structure performs all these functions, reducing the need for additional specialized components.

Function Achieved in This Case
This configuration effectively prevents water from entering the goggles by maintaining a secure fit of the contact parts to the eyes, significantly enhancing the waterproofing effect.
Implementation Method 1
an elastic waterproofing ring sealed on an inner side of the rim... the elastic waterproofing ring includes a first connection part fixedly connected to the rim, a support part connected to the first connection part, a left-eye contact part connected to the support part and to be pressed against an outer contour of a left eye
Implementation Method 2
A left side of the head band is fixedly connected to the left-eye contact part, and a right side thereof is fixedly connected to the right-eye contact part. The left side of the head band may apply a pulling force towards the user's head on the left-eye contact part
