Device for improving room air quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for improving indoor air quality often focus on only one aspect, such as odor reduction or pollutant removal, without addressing the comprehensive improvement of indoor air quality, and are either expensive or difficult to install and retrofit.
Innovation Solution
A device that includes a conveying system for air circulation, a filtering system with multiple filters, a scenting system using wood or essential oils, a planting facility for CO2 conversion, and a disinfection system, along with a humidification and control unit, to enhance air quality by filtering pollutants, improving odor, increasing oxygen levels, and reducing health risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If controlled home ventilation is used to improve indoor air quality, then air quality is improved in several respects, but the system becomes very expensive, complex to install and difficult to retrofit
Solution Approach 1:
The device segments the air treatment process into distinct functional modules: a conveying device for air circulation, a filter device for pollutant removal, a scenting device for odor control, and a planting device for CO2 conversion. Each module performs a specific function, allowing the system to achieve comprehensive air quality improvement without requiring a complex integrated ventilation system.
Solution Approach 2:
The device combines multiple functions into a single unit that can filter pollutants, control odors, and convert CO2 simultaneously. The conveying device circulates air through all three treatment stages, making the system versatile and eliminating the need for separate ventilation, filtration, and plant-based air purification systems.
2Reliability
If multiple functional devices are combined to comprehensively improve indoor air quality, then air quality improvement is enhanced, but the device complexity increases
Solution Approach 1:
The patent merges the conveying device, filter device, scenting device, and planting device into a single integrated air treatment system. The conveying device serves as a common infrastructure that transports air through all functional stages, reducing the need for separate systems and simplifying installation while maintaining comprehensive air quality improvement.
3Object-affected harmful factors
If a filter device is used to remove pollutants, then health risks are reduced, but the device complexity and cost increase
Solution Approach 1:
The filter device is segmented into multiple filter stages with different functions: pre-filters for large particles, HEPA filters for fine particles and viruses, and activated carbon filters for gases and odors. This segmentation allows each filter type to target specific pollutants efficiently, reducing the need for overly complex single-stage filtration systems.
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 filters pollutants, reduces health risks, improves well-being by reducing heartbeat rate and enhancing concentration and sleep quality, and can be easily retrofitted, providing comprehensive and objective monitoring and control of indoor air quality.
