Solution Overview

Problem

Existing masks struggle with inconsistent fit to the face, leading to unfiltered air entry or exit through edges, discomfort, and increased risk of virus transmission due to inadequate sealing.

Innovation Solution

A mask-holder device made of flexible and deformable wires with a central bridge and side pins that adapt to the face, ensuring secure fastening and sealing, with optional folding features for easy storage and multiple attachment options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional elastic bands or ties are used to fasten masks, then the mask can be secured to the face, but the fit is inconsistent with gaps appearing in some areas while being too loose in others

Engineering Contradiction:
Improvemask sealing effectivenessVSAvoidmask fit consistency
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent uses a flexible wire structure that can be deformed and bent to match the contours of different face shapes. The wire includes a bridge portion that adapts to the nose bridge area and side portions that extend along the cheeks, providing consistent contact and sealing across various face geometries without requiring complex adjustment mechanisms.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent employs a wire with varying cross-sectional properties along its length, with different portions having different flexibility characteristics. The bridge portion has specific rigidity to maintain structural support, while the side portions are more flexible to conform to cheek contours, allowing the single wire structure to provide both support and adaptive sealing.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If masks are made to fit certain face shapes, then sealing is improved for those users, but the mask becomes loose or uncomfortable for users with different face shapes

Engineering Contradiction:
Improveair filtration effectivenessVSAvoidface shape compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent designs a universal wire structure that can adapt to multiple face shapes and sizes. The bridge portion and side portions are configured to work together as an integrated system that conforms to various facial geometries, making the mask suitable for different users without requiring multiple size variants or complex adjustment mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses a flexible wire that can dynamically deform and reshape itself to match the user's face contours. The wire's flexibility allows it to be molded during fitting and to maintain adaptive contact as the user moves or speaks, providing consistent sealing across different expressions and activities.

Inventive Principle:
Principle #15Dynamics

3Reliability

If masks are secured tightly to prevent leakage, then filtration is improved, but comfort decreases and users experience continuous awareness of mask placement

Engineering Contradiction:
Improveedge sealingVSAvoiduser comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent uses a flexible wire that distributes sealing pressure along the bridge and side portions rather than concentrating force at discrete attachment points. This distributed pressure system achieves effective edge sealing while reducing localized discomfort and the sensation of mask presence, improving overall user comfort during extended wear.

Inventive Principle:
Principle #30Flexible shells and thin films
