Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing masks that cover the nose and mouth are inadequate for preventing airborne and droplet infections, as they need to be removed for eating and may have gaps, and are difficult for certain individuals to wear, while existing non-enclosing devices lack effective mechanisms to block aerosols and sterilize without physical barriers.

Innovation Solution

A non-enclosing device using diamagnetic and wind forces to push aerosols away from the face, combined with a visible-light sterilization mechanism, detachably attachable to the body to allow safe consumption and conversation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mask is worn to block droplets and aerosols, then protection against airborne and droplet infection is improved, but the mouth and nose must be covered making eating difficult and requiring mask removal

Engineering Contradiction:

Improveprotection against airborne and droplet infectionVSAvoidconvenience during eating

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The protective function is segmented into two independent components: a physical barrier (mask) and an active blocking system (diamagnetic and wind force generators). This allows the active system to provide continuous protection without requiring physical contact with the face, enabling eating convenience while maintaining infection protection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The traditional mechanical barrier (mask covering mouth and nose) is replaced with a field-based system using diamagnetic force and wind force. This substitution eliminates the need for physical enclosure while maintaining the blocking function against droplets and aerosols.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If a mask is worn to block droplets and aerosols, then protection against airborne and droplet infection is improved, but infants and patients with certain conditions have difficulty wearing masks

Engineering Contradiction:

Improveprotection against airborne and droplet infectionVSAvoidease of wearing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system replaces the mechanical mask structure with a field-based active blocking system. This eliminates the need for physical fitting and wearing, making it accessible to infants and patients who cannot properly wear traditional masks.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The active blocking system using diamagnetic and wind forces provides universal protection that can be applied to various users regardless of age or physical condition, unlike size-specific masks that require proper fitting.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If a mask is worn to block droplets and aerosols, then protection against contact infection is improved, but the mask itself may become contaminated requiring frequent replacement

Engineering Contradiction:

Improveprotection against contact infectionVSAvoidmask contamination and replacement

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The contamination risk is extracted from the user's immediate environment by using a detachable sterilization lamp that can be separated from the main device. The lamp can be sterilized independently through autoclaving or other methods, preventing cross-contamination while maintaining continuous protection capability.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A non-enclosing device for blocking viruses and bacteria, according to the present invention, comprises: a main body that can be attached/detached to/from the body of a user; and a blocking part provided at the main body so as to block droplets or aerosols from entering the respiratory system of the user. The present invention can provide the non-enclosing device for blocking viruses and bacteria, the device using diamagnetism and wind power so as to push droplets and aerosols away from the face of a user such that the entering of the droplets or aerosols into the respiratory system and the outward spreading of the droplets of the user are blocked, and emitting visible sterilization light, which is harmless to the human body, so that viruses and bacteria contained in droplets and aerosols are killed.
