Solution Overview

Problem

Existing face coverings, such as surgical masks, face difficulties in user recognition, odor management, and microbiological load control, particularly when reused, posing risks of virus spread and health issues.

Innovation Solution

A dual-function accessory device with a decorative identification element and a diffuser for fragrances/essential oils, using magnetic coupling, to enhance user recognition and reduce bacterial/viral load, while being reusable and comfortable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a face covering is removed and placed on a surface for temporary use, then the user can perform operations, but the mask cannot be recognized for sure among other masks of the same type

Engineering Contradiction:
Improvemask identificationVSAvoidvirus spread risk
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The patent applies color changes by using decorative elements with different colors, patterns, or visual characteristics on the face coverings. These visual markers enable users to distinguish their own mask from others, preventing accidental use of the wrong mask and reducing virus spread risk while allowing temporary placement on surfaces.

Inventive Principle:
Principle #32Color changes

2Reliability

If the face covering covers the user's nose and mouth for protection, then viral protection is provided, but unpleasant odors are concentrated inside the face covering

Engineering Contradiction:
Improveviral protectionVSAvoidunpleasant odors
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary substance (such as activated carbon, charcoal, or other odor-absorbing materials) placed within the face covering structure. This intermediary layer absorbs unpleasant odors and volatile compounds while maintaining the protective barrier function, thus mediating between the need for coverage and the need for comfort.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the face covering is reused for prolonged periods, then resource efficiency is improved, but the microbiological load increases to values that can lead to pathological events

Engineering Contradiction:
Improvereuse efficiencyVSAvoidmicrobiological load
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent incorporates strong oxidants or antimicrobial agents (such as silver ions, copper compounds, or other disinfecting materials) into the face covering structure. These substances actively reduce microbiological load through oxidation and antimicrobial action, enabling safe prolonged reuse while preventing pathological events caused by bacterial or viral accumulation.

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)

4Ease of operation

If accessories such as glasses and hats are worn with the face covering, then user comfort is improved, but the already limited visibility is further reduced

Engineering Contradiction:
Improveuser comfortVSAvoidvisibility
Core Design Contradiction:
Ease of operationVSIllumination intensity

Solution Approach 1:

The patent addresses visibility issues by incorporating transparent or translucent materials in strategic dimensions of the face covering design. This allows light to pass through certain areas (such as the eye region or upper face area) while maintaining protection, thus adding a dimensional solution that reconciles accessory wearability with visibility requirements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The present invention concerns an accessory device for face coverings, surgical masks and filtering facepieces, which performs the dual function of a diffuser, in particular of fragrances and scents to neutralise unpleasant odours that may form in the area in front of the user's mouth, and also as a sign of recognition of its own mask by the user.
