Waterproof Goggle Leaning Structure with Variable Protrusions

Solution Overview

Problem

The challenge is to create waterproof goggles that can fit a wide range of facial shapes and sizes without incurring excessive manufacturing costs, as existing designs struggle to accommodate the diversity of human facial anatomy.

Innovation Solution

The waterproof goggle features a frame structure with two rings and a bridge, along with a flexible waterproof leaning structure that includes alternately disposed protrusions and recesses on its outer surface, allowing for curvature and varying widths to accommodate different facial shapes, ensuring a secure and comfortable fit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If waterproof goggles are designed to fit specific facial shapes, then the waterproof effect and comfort are improved, but the manufacturing cost increases due to the need for multiple models

Engineering Contradiction:

Improvewaterproof effectVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The leaning structure is designed with protrusions and recesses that enable it to adapt to multiple facial shapes and sizes with a single mold, allowing one goggle model to serve diverse users while maintaining waterproof performance

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The protrusions and recesses are strategically positioned on the leaning structure to provide localized adaptation to different facial contours, enabling the structure to conform to various facial shapes without requiring multiple complete goggle models

Inventive Principle:

Principle #3Local quality

2Ease of operation

If waterproof goggles are designed to fit specific facial shapes, then the comfort and seal are improved, but the device complexity increases due to the need for multiple models

AI summary

A waterproof goggle is provided and includes a frame structure, a lens set and a waterproof leaning structure. The lens set is disposed in the frame structure and the waterproof leaning structure is waterproofly connected to the frame structure. The waterproof leaning structure includes an outer surface, an inner surface, several protrusions and several recesses; the outer surface is opposite to the inner surface, and the protrusions and recesses are alternately disposed on the outer surface; the protrusions are curvedly extended along a longitudinal direction from a front edge to a rear edge of the outer surface, and widths of each of the protrusions are varied along the longitudinal direction. Therefore, the leaning structure can be more easily stretched to fit different users' faces.
