Eyewear Facemask with Temple-Mounted Support for Reduced Fogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearing eyewear and facemasks together can cause discomfort and fogging due to the facemask components looping around the ears and shifting, leading to weight distribution issues and lens fogging.
Innovation Solution
An eyewear facemask with loop connectors at the top corners attaching to eyewear temples, expandable elastic portions, and a removable strap for secure and comfortable wear, reducing ear pressure and fogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional facemasks with ear loops are worn with eyewear, then the facemask can be secured to the face, but the weight is concentrated on the ears causing discomfort and the facemask may shift causing lens fogging
Solution Approach 1:
The facemask attachment system is segmented into multiple connection points: two connectors at the top corners attach to the eyewear temples, while elastic portions are distributed along the edges (top, bottom, and side edges) to provide segmented support around the face, distributing weight away from the ears
Solution Approach 2:
The eyewear temples serve as an intermediary structure to bear the weight of the facemask. By attaching connectors to the temples rather than having ear loops directly contact the ears, the eyewear framework acts as a mediator to distribute the load across the nose bridge and temples
2Reliability
If facemask loops around ears are used, then the facemask can be retained on the face, but the facemask shifts causing discomfort and lens fogging
Solution Approach 1:
The elastic portions provide dynamic adaptation to the wearer's face shape and movements. The elastic material can stretch and flex to maintain consistent retention force while accommodating facial expressions and movements, preventing the facemask from shifting position
Solution Approach 2:
Elastic portions are integrated along the edges of the facemask to create a flexible sealing system that conforms to the contours of the face, providing reliable retention without rigid structures that could cause discomfort or shifting
3Duration of action of moving object
If facemask is worn with eyewear for extended periods, then protection is maintained, but discomfort and lens fogging increase
Solution Approach 1:
The retention system is segmented into multiple independent elastic portions distributed along different edges of the facemask. This segmentation allows each portion to independently maintain tension and support, distributing the burden across multiple contact points rather than concentrating stress, thereby enabling comfortable extended wear
Solution Approach 2:
The eyewear structure serves as an intermediary that assumes the primary weight-bearing function, allowing the facemask to be retained without direct pressure on the ears. This mediation enables prolonged wear by transferring the mechanical load to the eyewear framework
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 comfortable, extended wear with reduced fogging and aesthetic appeal by distributing weight to eyewear temples and using elastic attachments for a cupped fit, enhancing user comfort and versatility.
Implementation Method 1
The first, second, third, and fourth elastic attachments can combine with the covering portion to form a cup shape, wherein the cup shape of the covering portion encloses at least part of the user's nose, mouth, and/or chin.

AI summary
A face mask system can include eyeglasses and a face mask. The eyeglasses can be worn by a user and can have first and second temples that can extend at least partially behind ears of the user to secure the eyeglasses to a face of the user. The face mask can be removably attached to the eyeglasses when worn by the user. The face mask can have a covering portion sized and shaped to cover at least part of a user's nose and/or mouth, a first connector extending from the covering portion to the first temple of the eyeglasses, and a second connector extending from the covering portion to the second temple of the eyeglasses.
