Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pest control methods using chemical insecticides and pesticides pose environmental risks, lead to resistance, and affect non-target organisms, while also contaminating the food chain and groundwater.
Innovation Solution
A method involving the oxidative treatment of materials using a sprayable formulation of organic ozonides and hydroperoxides, which are produced by reacting unsaturated fatty acids with ozone-containing oxygen, providing a non-specific, effective, and environmentally friendly solution for pest control on plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical insecticides and pesticides are used for pest control, then pest control effectiveness is improved, but environmental harm and resistance development worsen
Solution Approach 1:
The patent employs ozone, a strong oxidant, to generate organic ozonides and hydroperoxides in situ on plant surfaces. These oxidative agents effectively control pests through non-specific oxidation mechanisms that do not rely on chemical toxicity, thereby avoiding environmental contamination and resistance development while maintaining pest control effectiveness.
Solution Approach 2:
The invention replaces chemical toxicological mechanisms with physical-chemical oxidative mechanisms. Instead of using chemically toxic substances that harm the environment, the system uses oxidative reactions initiated by ozone to achieve pest control, substituting a harmful chemical approach with a cleaner physicochemical process.
2Reliability
If chemical control substances are applied, then pest control is achieved, but substance accumulation in plants and food chain contamination worsen
Solution Approach 1:
Ozone and the resulting oxidative products act on plant surfaces and pests without being absorbed and accumulated in plant tissues. The oxidative mechanism works externally on pests and pathogens, preventing substance accumulation in the food chain while maintaining effective pest control.
Solution Approach 2:
The oxidative agents (ozone, ozonides, hydroperoxides) are transient substances that decompose rapidly into oxygen and water after performing their pest control function. This short-lived nature prevents accumulation in plants and the environment, unlike persistent chemical pesticides.
3Adaptability or versatility
If broad-spectrum chemical pesticides are used, then pest control coverage is improved, but harm to non-target organisms worsens
Solution Approach 1:
Oxidative agents act through non-specific oxidation chemistry that affects pests, fungi, and bacteria regardless of their biological classification. This mechanism provides broad-spectrum coverage while being inherently selective for organisms with high metabolic activity, sparing beneficial organisms and non-target species.
Solution Approach 2:
The oxidative treatment system provides universal pest control coverage against insects, fungi, bacteria, and viruses through a single mechanism. This multi-functional approach eliminates the need for multiple specialized chemicals, reducing overall environmental impact on non-target organisms.
4Reliability
If chemical substances are applied to plants, then pest control is achieved, but groundwater contamination worsens
Solution Approach 1:
Ozone and its reaction products are highly reactive and short-lived, decomposing into oxygen and water before reaching groundwater. The oxidative mechanism achieves effective pest control at the plant surface without generating persistent contaminants that could migrate to groundwater systems.
Solution Approach 2:
The use of transient oxidative agents that decompose rapidly prevents long-term environmental persistence and groundwater contamination. These short-lived substances complete their pest control function and break down before having the opportunity to contaminate groundwater resources.

AI summary
In a method for oxidative treatment of material, organic ozonides and/or organic hydroperoxides are provided in a mixture with water and are applied to the material by spraying. The organic ozonides and/or organic hydroperoxides are prepared by treating unsaturated fatty acids with ozone-containing oxygen, the peroxide number (PON) of the organic ozonides and/or organic hydroperoxides being set to a figure of between 50 and 5000 meq/kg. The method can be used in particular for pest control on plants.
