Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air purification systems are inadequate in addressing complex atmospheric pollution, particularly in urban areas, as they fail to effectively remove particulate matter and other pollutants, and lack the ability to release clean air back into the atmosphere, posing health risks to humans and animals.
Innovation Solution
An energy-efficient air purification system comprising multiple air pollution monitoring units and purification units with an automated control unit that remotely manages the purification process, using a combination of air filtration components like wet scrubbers, electrostatic precipitators, and catalytic filters to filter pollutants and release clean air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If catalytic converters are used to treat NOx and SOx gases, then emission control is improved, but solid particulate matter such as PM2.5 and PM10 are still released into the atmosphere
Solution Approach 1:
The air purification system is divided into multiple independent purification units distributed at different locations, each equipped with specific filtration components. This segmentation allows the system to address different types of pollutants (gases and particulates) at various spatial points, preventing the limitation of single-location treatment and enabling comprehensive removal of both gaseous and solid particulate matter that catalytic converters alone cannot remove.
Solution Approach 2:
Different purification units are equipped with different air cleaning components based on local pollution characteristics. Some units use wet scrubbers for gas absorption, others use electrostatic precipitators for particulate removal, and some use catalytic filters for specific gas conversion. This local quality approach ensures that each location's specific pollution mix (gaseous or particulate) is optimally treated, addressing the contradiction between gas control and particulate removal.
2Object-affected harmful factors
If air purification systems are deployed to remove pollutants, then air quality is improved, but energy consumption increases
Solution Approach 1:
The system uses automated control units that periodically monitor air quality parameters and activate purification units only when pollution levels exceed predetermined thresholds. This periodic action replaces continuous operation, allowing the system to maintain improved air quality while significantly reducing energy consumption by operating only when and where needed based on real-time conditions.
Solution Approach 2:
The purification system incorporates automated control units that self-monitor air quality and autonomously activate or deactivate purification units based on detected pollution levels. This self-service capability eliminates the need for continuous manual operation and enables the system to automatically optimize energy usage while maintaining air quality improvement, as units are activated only when pollution requires intervention.
3Area of stationary object
If multiple air purification units are installed at distant locations, then coverage area is improved, but system complexity increases
Solution Approach 1:
Each distributed purification unit is designed as a universal module capable of performing multiple functions: monitoring local air quality, filtering gaseous pollutants, removing solid particulates, and communicating with the central control system. This multi-functionality allows the system to achieve broad geographic coverage through multiple units while reducing overall complexity, as each unit is a self-contained universal device rather than requiring specialized components at each location.
Solution Approach 2:
The system implements feedback loops where automated control units continuously monitor air quality data from multiple purification units and adjust their operation accordingly. This feedback mechanism simplifies the management of distributed units by enabling centralized automated control, where the control system coordinates all units based on real-time conditions, reducing the operational complexity that would otherwise arise from managing multiple geographically dispersed devices.
