Solution Overview

Problem

There is a need for a system that effectively reduces the risk of COVID-19 transmission in environments where close physical proximity between individuals cannot be avoided, particularly in healthcare settings like dentistry, where droplet and aerosolized transmission poses a high risk to both healthcare workers and patients.

Innovation Solution

A protective apparatus comprising a transparent shield component and a handle component, which can be attached to a vacuum hose or other cylindrical object, featuring a camera and LED lighting to enhance visibility and minimize direct and indirect contact, and is designed to be positioned close to the patient without obstructing the view or comfort of the healthcare worker.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a transparent shield is held in front of the face to block droplets, then protection against infection is improved, but the ability to see and interact with others is reduced

Engineering Contradiction:
Improveprotection against infectionVSAvoidability to see and interact
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

A transparent shield is introduced as an intermediary barrier between individuals, allowing visual contact and interaction to be maintained while physically blocking droplet transmission. The transparency of the shield serves as the mediator that preserves social interaction capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The shield functions as a thin film barrier that is transparent yet effective at blocking droplets. This thin film approach provides protection without significantly obstructing vision or interaction, resolving the contradiction between protection and ease of operation.

Inventive Principle:
Principle #30Flexible shells and thin films

2Reliability

If masks are worn to block droplets, then protection against infection is improved, but communication clarity and breathability are reduced

Engineering Contradiction:
Improveprotection against infectionVSAvoidmuffled communication and breathing difficulty
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The harmful effects of traditional masks (muffling communication, breathing difficulty) are extracted and removed from the solution. Instead of using masks that cover the mouth and nose, the invention uses a shield that blocks droplets without obstructing speech or breathing, eliminating the harmful side effects while maintaining protection.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If social distancing is maintained to reduce transmission risk, then protection against infection is improved, but productivity and social interaction are reduced

Engineering Contradiction:
Improveprotection against infectionVSAvoidwork efficiency and social interaction
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The transparent shield serves as a mediator that enables individuals to be in close proximity without direct droplet transmission risk. This allows productivity and social interaction to be maintained at normal distances while the shield provides the necessary protection, eliminating the need for social distancing.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Device complexity

If no visual indicators are provided on shields, then simplicity is maintained, but awareness of infected individuals cannot be signaled

Engineering Contradiction:
Improveshield simplicityVSAvoidinfection status visibility
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

Color-changing indicators are integrated into the shield that change color based on the proximity of infected individuals. This allows infection status information to be communicated visually without adding significant complexity to the shield design, resolving the contradiction between simplicity and information transmission.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The shield incorporates indicators that change their optical parameters (color, brightness) in response to detected conditions such as proximity to infected individuals. This parameter change provides visual information about infection risk while maintaining relative simplicity in the overall shield structure.

Inventive Principle:
Principle #35Parameter changes
