Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods struggle to effectively purify outside air due to pollutants generated by vehicles, such as dust from tires and brake pads, and existing air purification systems are inefficient and costly, with limited coverage and high energy consumption.
Innovation Solution
An outside air purification system for vehicles, comprising a cooling fan, duct, dust collection unit with ionization and electrode plates, and a control unit that operates based on dust concentration, vehicle speed, and weather conditions to purify air using traveling wind and minimize energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air purification buildings are constructed in areas with severe air pollution, then air purification performance in areas close to the building is improved, but construction costs become enormous and noise is generated
Solution Approach 1:
The patent divides the air purification function into multiple mobile units (vehicles) distributed across the area, rather than using a single large stationary building. Each vehicle acts as an independent purification node, collectively providing coverage across the entire region while reducing individual unit costs and eliminating centralized noise problems.
Solution Approach 2:
The system utilizes the natural movement of vehicles through traffic to perform air purification duties. Vehicles already circulating in polluted areas are converted into mobile purification units, eliminating the need for dedicated stationary infrastructure and allowing the system to serve multiple locations dynamically without fixed construction costs.
2Reliability
If air purification buildings are constructed in areas with severe air pollution, then air purification performance in areas close to the building is improved, but noise is generated due to operation
Solution Approach 1:
By distributing multiple low-power mobile purification units across the area rather than concentrating power in a single stationary building, the system reduces localized noise intensity at any given location while maintaining overall purification effectiveness through collective operation of dispersed units.
Solution Approach 2:
The system transitions from static stationary buildings to dynamic mobile vehicles that move through different areas. This mobility allows purification units to relocate based on pollution levels, avoiding permanent noise sources and enabling service to multiple zones without generating fixed-location noise complaints.
3Reliability
If conventional air purification systems operate continuously, then air purification performance is maintained, but power consumption becomes high
Solution Approach 1:
The system operates purification units periodically based on real-time pollution monitoring rather than continuously. Vehicles activate their purification systems when passing through high-pollution areas and remain inactive in cleaner zones, significantly reducing overall power consumption while maintaining effective air purification where needed most.
Solution Approach 2:
The system incorporates dust concentration sensors that provide real-time feedback on air quality conditions. This feedback controls the activation and operation intensity of purification units, ensuring they operate only when and where pollution levels warrant intervention, thereby optimizing energy usage based on actual environmental conditions.
4Reliability
If vehicle speed is high, then air purification efficiency is reduced, but traveling wind provides natural air flow
Solution Approach 1:
The system exploits the natural air flow generated by vehicle movement itself to supply dust-laden air to the purification unit. The vehicle's own traveling wind becomes the driving force for air intake, eliminating or reducing the need for additional power-consuming fans or pumps to move air through the purification system.
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 efficiently purifies air by adsorbing pollutants using vehicle-mounted equipment, providing uniform air purification across areas without concentrated noise or high energy consumption, and preventing re-pollution by collecting pollutants through a water filter.
Implementation Method 1
an ionization line installed at an inlet of the dust collection unit and configured to generate a high voltage when power is applied to the dust collection unit
Implementation Method 2
a plurality of electrode plates installed behind the ionization line and disposed parallel to each other. The plurality of electrode plates is configured to be charged when the power is applied to the dust collection unit. The pollutants contained in the air flowing into the dust collection unit may be charged while passing through the ionization line and adsorbed to the plurality of electrode plates

AI summary
An outside air purification system for a vehicle includes a cooling fan installed on a roof of a vehicle, a duct for guiding air to the cooling fan, and a dust collection unit for adsorbing pollutants contained in the air flowing through the duct, which collects and adsorbs pollutants contained in the air while the vehicle travels on the road, thereby purifying outside air of the vehicle.
