Solution Overview

Problem

Conventional face coverings hinder communication by obstructing both auditory and visual cues, leading to misunderstandings and difficulties in conveying expressions, especially in contexts like the COVID-19 pandemic where physical distancing further complicates human interaction.

Innovation Solution

Integration of microphones, cameras, displays, and processing capabilities into face coverings to capture and process audio and visual input, enabling the presentation of output in various modalities, such as audio and visual representations of obscured expressions, to enhance communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional face coverings are worn to protect against infection, then protective function is improved, but communication ability deteriorates

Engineering Contradiction:

Improveprotective functionVSAvoidcommunication ability

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces an intermediary communication system that includes microphones, cameras, displays, and speakers integrated into the face covering. This intermediary system captures audio and visual input, processes it, and presents output to enable communication while the face covering remains in place for protection, thus resolving the contradiction between protective function and communication ability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The face covering is transformed into a multi-functional device that simultaneously provides protective function (filtering particles) and communication function (capturing, processing, and presenting audio-visual data). This universal design allows the single device to fulfill multiple purposes, resolving the contradiction between protection and communication

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If face coverings obstruct auditory and visual cues to provide protection, then protective function is improved, but understanding of speech and expressions deteriorates

Engineering Contradiction:

Improveprotective functionVSAvoiddetection of speech and expressions

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The patent replaces the mechanical/physical system of direct auditory and visual detection with an electronic sensor system. Microphones capture audio signals, cameras capture visual signals, and these electronic signals are processed to reconstruct speech and expressions, enabling detection despite the physical barrier of the face covering

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates copies of the obscured audio-visual information by capturing it through sensors (microphones and cameras) and presenting it through output devices (displays and speakers). This copying process allows the information to be transmitted without direct line-of-sight or unobstructed sound transmission, maintaining detection precision while providing protection

Inventive Principle:

Principle #26Copying

AI summary

Communications involving one or more people wearing face coverings are enhanced over one or more modalities using sensor integrations. In one particular example, a face covering device according to the implementations of this disclosure may include one or more microphones and one or more cameras which capture input directly from the wearer of the face covering device. The input is processed to produce output representing the input in the same modality or in a different modality, and in particular is scaled to, for example, increase a volume of audio and introduce a visual representation of an expression of the wearer's face which is at least partially obscured by the face covering device.
