Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purification systems using ozone face challenges in maintaining effective air cleaning without causing health hazards due to high ozone concentrations, requiring continuous and efficient solutions for large volumes of air in commercial settings, and existing technologies are complex, costly, and require frequent maintenance.
Innovation Solution
An air treatment system comprising an elongate support body with a fan unit and an air treatment unit that generates ozone and ionizes air using UV lamps within the duct, ensuring ozone concentration decreases before air exit, providing continuous air circulation and purification without exposing the room to harmful ozone levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high concentration of ozone is used for air purification, then air cleaning effectiveness is improved, but health hazards increase
Solution Approach 1:
The system divides the air treatment process into two separate chambers: a first chamber for generating high ozone concentration to effectively clean pollutants, and a second chamber for reducing ozone concentration to safe levels before discharge. This segmentation allows the system to achieve effective air purification while eliminating health hazards from high ozone exposure.
Solution Approach 2:
The patent introduces an intermediary reducing chamber between the ozone generation chamber and the discharge point. This intermediary chamber, equipped with ozone reduction devices (catalytic converters, UV lamps, or chemical scrubbers), acts as a mediator that transforms harmful high-concentration ozone into safe low-concentration air, thereby resolving the contradiction between cleaning effectiveness and health safety.
2Reliability
If one-time air cleaning with ozone is performed, then pollutants are removed temporarily, but operational downtime occurs and pollution returns
Solution Approach 1:
The system enables continuous air purification by continuously circulating air through the ozone generation chamber and the reducing chamber. Unlike one-time treatments that require shutdown, this continuous circulation process maintains constant pollutant removal without operational downtime, and the discharged air is already treated to safe ozone levels, preventing pollution recurrence.
Solution Approach 2:
The system performs preliminary ozone reduction in the second chamber before air is discharged back into the environment. This preliminary action ensures that pollutants are removed and ozone concentration is reduced to safe levels continuously, preventing the need for repeated one-time cleaning operations and eliminating operational downtime.
3Reliability
If existing air purification systems are used, then air cleaning is achieved, but system complexity and cost increase
Solution Approach 1:
The patent merges the ozone generation function and the ozone reduction function into a single integrated air treatment system with two connected chambers. This merging approach achieves effective air cleaning while avoiding the complexity and high costs of separate independent systems, as the two functions work together in a unified configuration with shared air circulation infrastructure.
