Protective Eyewear with Central Raised Portion for Airflow and Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective eyewear restricts natural air cooling and viewing areas, leading to discomfort and fogging issues during intense activities, while conventional frame designs often hinder visibility and airflow management.
Innovation Solution
The design includes a frame with an outer surface oriented away from the face and an inner surface oriented towards the face, featuring cooling vents and a central raised portion to enhance airflow and provide an extended vertical view, with a lens configuration that covers both eyes and includes adjustable airflow features to prevent fogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional frame designs are used to provide protection and fit, then eye protection and secure fit are improved, but viewing area and airflow are restricted
Solution Approach 1:
The patent introduces a central raised portion that extends vertically above the continuous profile of the left and right portions, adding vertical dimension to the frame structure. This dimensional change allows the lens to provide extended vertical viewing area while the frame maintains its protective function, resolving the contradiction between protection and viewing area.
2Reliability
If conventional frame designs are used to provide protection and fit, then eye protection and secure fit are improved, but natural air cooling is restricted
Solution Approach 1:
The frame is segmented into distinct functional portions: left and right portions for protection and fit, and a central raised portion for airflow management. This segmentation allows each portion to optimize its specific function while contributing to the overall protective performance, resolving the contradiction between protection and air cooling.
3Reliability
If smooth laminar airflow is provided across the back surface of the lens, then fogging prevention is improved, but natural air cooling is restricted
Solution Approach 1:
The central raised portion acts as an intermediary structure that manages airflow between the lens and the environment. It provides a controlled path for air to flow across the back surface of the lens (preventing fogging) while also allowing natural air cooling to occur through the frame structure, thus resolving the contradiction between fogging prevention and air cooling.
4Ease of manufacture
If the frame profile is made continuous for structural integrity, then manufacturing and fit are simplified, but vertical viewing area is restricted
Solution Approach 1:
The central raised portion extends in the vertical dimension above the continuous profile level, creating an extended vertical viewing area. This vertical extension is manufactured as part of the frame structure, maintaining ease of manufacture while significantly increasing the vertical viewing area available to the user.

AI summary
Protective eyewear may include an eyewear frame including a left segment extending from a left pivotable temple and a right segment extending from a right pivotable temple. A lens is coupled directly to lower edges of the left and right segments, and the lens is configured to cover both eyes of a user when worn. An uppermost profile of the eyewear includes a discrete central raised portion extending upward from the left and right segments of the frame.
