Solution Overview
Problem
Existing air purifiers are not effective in providing controlled clean air flow for infection prevention, as they are often cumbersome, expensive, and not designed for portable use, failing to protect health workers from airborne viruses like COVID-19 and flu.
Innovation Solution
A portable, low-cost Clean-Air Partition System with a vertical tower design, featuring HEPA filters and a Smart Particle Sensor Actuator Set, which separates clean and infected air streams, directing infected air towards an exhaust HEPA filter and bringing clean air into a protected space, maintaining a unidirectional flow to prevent virus inhalation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal protection equipment (PPE) is used, then protection against airborne viruses is improved, but the system becomes cumbersome and expensive
Solution Approach 1:
The patent introduces a portable air purifier as an intermediary device that creates a protected air zone around the user without requiring full-body PPE. The purifier acts as a mediator between the contaminated environment and the user, filtering airborne pathogens and delivering clean air to the breathing zone, thus providing protection while maintaining mobility and communication capabilities.
Solution Approach 2:
The invention applies local quality by focusing protection on the critical breathing zone rather than the entire body. The portable purifier concentrates its filtering and air delivery functions on the local area around the user's head and shoulders, creating a clean air envelope where it is most needed, while leaving the rest of the body exposed but protected by the localized clean air field.
2Reliability
If full PPE systems are used, then protection against airborne viruses is improved, but communication and natural interaction are hindered
Solution Approach 1:
The portable air purifier provides protection locally around the breathing zone while leaving the face and upper body exposed, thereby maintaining the ability to communicate naturally through facial expressions, gestures, and verbal interaction without the obstruction of full-face masks or hoods.
Solution Approach 2:
The device serves as an intermediary that provides viral filtration in the air pathway without physically blocking the user's face or body, allowing natural human interaction and communication to proceed unimpeded while still delivering protected air to the respiratory zone.
3Productivity
If existing air purifiers are used, then air circulation is improved, but controlled clean air flow to selected mini-environment is not provided
Solution Approach 1:
The portable purifier segments the air treatment function by creating a distinct, controlled clean air zone around the user rather than mixing air throughout the entire room. The device uses directed airflow patterns and localized filtration to establish a segmented protected environment that moves with the user, providing adaptable clean air flow precisely where needed.
Solution Approach 2:
The system is designed to be dynamically adaptable to the user's movements and positioning. The purifier maintains controlled clean air flow to the selected mini-environment (user's breathing zone) as the user moves throughout the space, providing versatile protection that adjusts to changing positions and orientations rather than being fixed to a single location.
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 system effectively creates a clean climate in a controlled environment, protecting individuals from airborne pathogens by ensuring clean air is circulated while directing infected air away, thus reducing the risk of infection during interactions with potentially infected individuals.
