Strapless Facemask Adhesive Sealing for Full-Face Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fabric facemasks lack a mechanism to actively seal to a user's face, resulting in air bypassing the mask and reducing filtration efficiency, while strapless facemasks with integrated adhesives fail to account for varied face shapes, leading to gaps and inadequate protection.
Innovation Solution
A strapless facemask kit using multiple medical-grade adhesive strips and an optional metal strip to secure the facemask to the face, ensuring a full seal regardless of face contours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fabric facemasks are used without sealing mechanism, then the facemask structure is simple and easy to wear, but air bypasses the facemask and filtration protection is reduced
Solution Approach 1:
The adhesive sealing system is divided into multiple independent adhesive strips positioned at different locations (nose bridge, cheeks, chin) rather than using a single integrated sealing mechanism. This segmentation allows each strip to independently seal specific areas, achieving comprehensive sealing while maintaining simplicity of individual components.
Solution Approach 2:
Adhesive strips serve as an intermediary element between the facemask and the user's face, creating a sealing interface without requiring complex mechanical structures. The adhesive material acts as a mediator that bonds the mask to facial contours, eliminating air gaps while keeping the overall system simple.
2Reliability
If strapless facemasks with integrated adhesive are used, then the mask can be secured to the face, but the integrated adhesive fails to account for varied face shapes leading to gaps
Solution Approach 1:
The sealing system is segmented into multiple adjustable adhesive strips that can be independently positioned to accommodate different face shapes. Each strip can be placed at optimal locations (nose bridge, cheeks, chin) tailored to individual facial contours, providing adaptability across varied face shapes while maintaining reliable sealing.
Solution Approach 2:
The adhesive strip configuration is made dynamic and adjustable rather than fixed. Users can reposition and reconfigure the strips to match their unique facial geometry, allowing the sealing system to adapt to different face shapes and contours for optimal sealing effectiveness.
3Reliability
If multiple adhesive strips are used to secure the facemask, then a full seal is achieved, but the device complexity increases
Solution Approach 1:
The adhesive strips serve multiple functions: they secure the mask to the face, create airtight seals at critical locations, and accommodate various face shapes. This multi-functionality achieves complete sealing without requiring additional complex components, as the same adhesive strips perform multiple sealing and securing roles.
Solution Approach 2:
The adhesive strips are designed to be self-positioning and self-adjusting to achieve proper sealing. The user simply applies the strips to the appropriate facial locations, and the adhesive properties ensure proper adhesion and sealing without requiring complex alignment mechanisms or additional tools.

AI summary
In a method of securing a strapless facemask to a user's face, a first portion of a first strip of adhesive material is attached to a first side of the strapless facemask and a first portion of a second strip of the adhesive material is attached to a second side of the strapless facemask. The strapless facemask is placed over the user's face. A second portion of the first strip of the adhesive material and a second portion of the second strip of the adhesive material are adhered to the user's cheeks. A first portion of a third strip of adhesive material is adhered to the bottom of the strapless facemask and a second portion of the third strip of the adhesive material is adhered to the user's chin. A first portion of a fourth strip of adhesive material is adhered to the top of the strapless facemask and a second portion of the fourth strip of the adhesive material is adhered to the user's nose and the user's cheeks, achieving a full seal to the user's face.
