Solution Overview

Problem

Existing face protectors, such as masks and face shields, are either constantly worn, obstructing oxygen intake, or require careful removal and sanitation to avoid contamination, posing risks and discomfort.

Innovation Solution

A smart multi-function protector with flexible protection sheets and embedded sensors dynamically deploys protection based on proximity to others, using ultraviolet radiation or liquid sanitization to ensure cleanliness without constant wear.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a face mask or face shield is worn continuously to protect against bacteria and viruses, then protection effectiveness is improved, but oxygen intake is reduced and breathing becomes difficult

Engineering Contradiction:

Improveprotection effectivenessVSAvoidoxygen intake

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The protection sheet is designed to be dynamically deployable and retractable rather than fixed. It can be extended to provide protection when needed and retracted to allow free breathing when protection is not required, making the protective system adaptive to changing environmental conditions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The protection sheet operates in periodic cycles of deployment and retraction based on detected environmental conditions. Sensors continuously monitor for nearby people or contaminants, triggering protection deployment only when necessary, thereby alternating between protected and breathable states

Inventive Principle:

Principle #19Periodic action

2Use of energy by moving object

If a face mask or face shield is removed when not needed, then oxygen intake is improved, but contamination risk increases due to improper handling and sanitation

Engineering Contradiction:

Improveoxygen intakeVSAvoidcontamination risk

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The system incorporates automated sanitation capabilities that continuously or periodically treat the protection sheet without requiring user intervention. This self-sanitizing function maintains hygiene automatically, eliminating the need for careful manual handling and sanitation procedures

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Sensors continuously monitor environmental conditions and provide feedback to the control system, which automatically adjusts protection deployment and sanitation cycles accordingly. This closed-loop control ensures protection is maintained while minimizing unnecessary deployment that would require sanitation

Inventive Principle:

Principle #23Feedback

3Reliability

If a protection sheet is deployed to create a barrier, then protection against bacteria and viruses is improved, but oxygen intake is reduced

Engineering Contradiction:

Improveprotection effectivenessVSAvoidbreathing ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The protection sheet transitions between deployed and retracted states dynamically based on real-time sensor detection of nearby people or contaminants. This dynamic operation allows the system to provide protection only when necessary, maintaining breathing ease during normal activities

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the physical state and position of the protection sheet based on environmental parameters detected by sensors. When contamination risk exceeds thresholds, the sheet is deployed; when risk is low, it is retracted, thereby adapting protection levels to actual conditions

Inventive Principle:

Principle #35Parameter changes

AI summary

The present teaching relates to a protector capable of dynamically deploying protection to a user. Data is received from multiple sensors embedded in the protector, worn by a user on head and providing protection to the user when needed. Distances between the user and others appearing nearby detected based on the data are dynamically tracked. If the protector is in a protection state, the protection is retracted when the tracked distances satisfy a first condition. The state of the protector is reset to a no-protection state. If the protector is in a no-protection state, the protector applies the protection to the user, when a second condition is satisfied based on the tracked distances, by releasing one or more protection shields from the protector to create a barrier between the user and others and the state of the protector is reset to a protection state.
