Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If corona discharge ozone is used for air deodorization, then deodorization effectiveness is improved, but health safety deteriorates due to high ozone concentrations and harmful nitrogen species
Solution Approach 1:
The patent applies this principle by converting the harmful high-concentration ozone produced by corona discharge into beneficial low-concentration aqueous ozone through water absorption. The system captures the ozone-generating capability while eliminating the harmful effects by dissolving ozone in water, then using this aqueous solution as a safe deodorization agent that can be applied to surfaces and fabrics without respiratory risks.
Solution Approach 2:
Water serves as an intermediary substance between the corona discharge ozone generation process and the final deodorization application. The aqueous ozone solution acts as a mediator that transfers the deodorization function while eliminating the harmful gaseous ozone and nitrogen species, allowing safe application in human-occupied environments.
2Object-affected harmful factors
If aqueous ozone is used as a catalyst, then health safety is improved by reducing residual ozone, but device complexity increases due to additional components
Solution Approach 1:
The patent merges multiple functions into the aqueous ozone system: ozone generation through corona discharge, water absorption and dissolution, catalytic decomposition on titanium oxide surfaces, and deodorization application. This consolidation achieves safe residual ozone levels while managing system complexity through integrated functionality rather than separate sequential processes.
Solution Approach 2:
The patent replaces mechanical ozone destruction methods with chemical catalysis using titanium oxide. Instead of using complex mechanical systems to break down ozone, the system employs photocatalytic or chemical catalysis where titanium oxide surfaces naturally decompose ozone into oxygen, simplifying the overall system while achieving safe residual levels.
3Productivity
If titanium oxide and manganese dioxide particles are used with UV light, then ozone decomposition efficiency is improved, but energy consumption increases
Solution Approach 1:
The patent changes the operational parameters of the catalysts by exposing titanium oxide to UV light, which activates its photocatalytic properties. This parameter change (adding UV activation) significantly enhances ozone decomposition efficiency. The system balances the added energy input from UV lights against the greatly improved decomposition rate, achieving net positive efficiency gains in ozone elimination.

AI summary
The present invention relates to an air deodorizing system and method that utilizes aqueous ozone as a catalyst to improve air quality by neutralizing odors, and volatile organic compounds (VOCs). The system includes an electrochemical ozone generator that forms aqueous ozone gas and oxygen gas from a water source. A blower creates an airflow extracted from the surrounding environment, combining it with the aqueous ozone gas and oxygen gas to form an oxidized airflow. The oxidized airflow interacts with titanium oxide and manganese dioxide particles, with or without ultraviolet (UV) light, to produce hydroxide molecules that break down pollutants. Residual humid aqueous ozone gas is reduced to a human-safe permissible level, and the deodorized airflow is vented back into the environment. The system may incorporate a dehumidifier to extract water from air, enabling self-sustained operation, and dynamically adjusting blower speed based on ozone concentration, ensuring safety and regulatory compliance.
