Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facemask devices are not effective in preventing airborne transmission of infectious diseases when not worn on the face, and there is a need for a handheld solution that allows professionals in beauty salons or barber shops to provide services without wearing a mask.
Innovation Solution
A handheld facemask device with a grippable handle, a panel with air holes for breathing, and a bacterial-blocking filter made of air-permeable material that can be positioned in front of the face to inhibit airborne transmission of infectious diseases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional face mask is worn on the user's face, then airborne transmission of infectious diseases is inhibited, but the user cannot breathe comfortably and visibility is obstructed
Solution Approach 1:
The device segments the protective function from the face by using a handheld panel instead of a face-mounted mask. The panel is held in front of the face at a distance, separating the user's face from the protective barrier while allowing comfortable breathing and visibility.
Solution Approach 2:
The handheld panel acts as an intermediary between the user and the environment. It provides bacterial blocking protection without requiring direct contact with the user's face, serving as a mediator that protects while maintaining comfort and visibility.
2Ease of operation
If a handheld panel with filter is positioned in front of the face, then airborne transmission is prevented without obstructing breathing, but the device complexity increases
Solution Approach 1:
The handheld panel serves multiple functions: it provides bacterial blocking protection, allows breathing through air holes, maintains visibility, and can be positioned at various distances from the face. This multi-functionality justifies the added device complexity by delivering multiple benefits from a single device.
Solution Approach 2:
The filter material is designed to be porous and air-permeable, allowing breath to pass through while blocking bacteria. This use of porous materials enables the device to provide protection without obstructing breathing, balancing safety with comfort.
3Reliability
If a filter made of bacterial blocking material is used, then transmission of infectious diseases is inhibited, but the filter may clog and reduce breathability
Solution Approach 1:
The filter is made from porous, air-permeable material that allows breath to pass through while trapping bacteria. The porous structure provides large surface area for bacterial capture while maintaining open pathways for air flow, preventing clogging and maintaining breathability.
Solution Approach 2:
The filter material parameters are optimized to balance bacterial blocking capability with breathability. By controlling pore size, material density, and thickness, the filter achieves effective bacterial capture while maintaining sufficient air permeability to prevent clogging and ensure comfortable breathing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively prevents the transmission of infectious diseases by allowing users to breathe through air holes while blocking bacteria, enabling professionals to work without wearing a traditional face mask.
Implementation Method 1
A filter is coupled to the panel and the filter is comprised of an air permeable material to facilitate the user to breathe through the filter. Moreover, the filter is comprised of a bacterial blocking material to inhibit bacteria from passing therethrough.

AI summary
A hand held facemask assembly includes a handle that can be gripped by a user. A panel is coupled to the handle such that the panel can be positioned in front of the user's face. The panel has a pair of air holes each extending therethrough to pass air therethrough thereby facilitating the user to breathe through the air holes. A filter is coupled to the panel and the filter is comprised of an air permeable material to facilitate the user to breathe through the filter. Moreover, the filter is comprised of a bacterial blocking material to inhibit bacteria from passing therethrough. In this way the filter inhibits airborne transmission of infectious diseases between the user and an individual that is positioned proximate the user.
