Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infectious disease control methods using protective clothing and negative pressure wards are inadequate in preventing medical workers from being infected during the treatment of COVID-19 patients, highlighting the need for an active air protection system to create a protective barrier around medical personnel.
Innovation Solution
A matrix wind field generation system with peripheral wind outlets devices is employed, which includes an air supply matrix and an air exhaust matrix. This system uses air supply devices and air exhaust devices arranged above and below a protected space, respectively, to control air flow rates and create positive or negative pressure around individuals, thereby forming an air protection barrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective clothing and negative pressure wards are used, then medical workers are protected to some extent, but the protection is insufficient and cluster infections still occur
Solution Approach 1:
The patent introduces an active air protection system as an intermediary between the medical worker and the infectious environment. This system uses air supply devices and air exhaust devices to create a controlled air flow field that acts as a protective barrier, mediating the interaction between the worker and pathogens. The system includes air supply outlets positioned around the worker and air exhaust outlets to maintain negative pressure, creating a directional air flow that prevents virus-laden aerosols from reaching the worker while allowing safe exhaust of contaminated air.
Solution Approach 2:
The patent applies pneumatic principles by using pressurized air supply devices and exhaust devices to create controlled air flow patterns. The air supply devices deliver pressurized air to specific zones around the worker, while exhaust devices create negative pressure zones. This pneumatic system generates dynamic air pressure differentials and directional air flows that actively push pathogens away from the worker, providing a more reliable protection mechanism than static protective clothing alone.
2Ease of operation
If standard protective clothing procedures are followed, then basic protection is provided, but absolute prevention of infection cannot be guaranteed
Solution Approach 1:
The system performs preliminary action by pre-establishing a controlled air flow environment before the medical worker enters the hazardous zone. The air supply devices are activated in advance to create positive pressure zones around the worker, and air exhaust devices are pre-positioned to establish negative pressure pathways. This preliminary setup ensures that protection is already in place before potential exposure occurs, rather than relying solely on reactive protective measures.
Solution Approach 2:
The system incorporates feedback mechanisms through air flow sensors and pressure sensors that continuously monitor the air flow field around the worker. This feedback information is used to dynamically adjust the air supply and exhaust device operations, ensuring that the protective air flow pattern is maintained consistently. The feedback loop allows the system to adapt to changing conditions and maintain reliable protection, addressing the insufficiency of static protective procedures.
3Object-generated harmful factors
If negative pressure wards are used, then virus spread is contained, but medical workers still face infection risk during patient treatment
Solution Approach 1:
The patent applies local quality by creating differentiated air flow zones with different pressure characteristics in different locations around the worker. The air supply devices create localized positive pressure zones directly around the worker's breathing zone and upper body, while air exhaust devices create localized negative pressure zones in other areas. This spatial variation in air flow properties provides enhanced protection to the worker while maintaining overall virus spread control in the ward environment.
Solution Approach 2:
The system adds a new dimension to protection by creating a three-dimensional air flow field around the worker, rather than relying on two-dimensional protective clothing coverage. The air supply devices are positioned at multiple heights and angles to create vertical and radial air flow patterns, while exhaust devices are positioned to create downward and outward air currents. This dimensional approach to air flow control provides comprehensive protection that addresses gaps in conventional protective measures.

Function Achieved in This Case
The system effectively reduces the risk of medical workers and related personnel being infected by creating a controlled air pressure environment that isolates them from pathogens in infectious disease control wards, enhancing the safety of medical staff and reducing the risk of infection.
