Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural practices rely heavily on chemical fertilizers and pesticides, which have negative environmental impacts, lead to soil degradation, and contribute to the contamination of water sources, while also posing risks to human health and ecosystems.
Innovation Solution
A composition comprising an aqueous dispersion of photocatalytic titanium dioxide (TiO2) and soluble silicon (Si), which provides biocidal properties and enhances plant resistance to biotic and abiotic stresses without leaving harmful residues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chemical fertilizers and pesticides are used to increase crop yield and protect against pests, then crop productivity is improved, but environmental contamination and human health risks worsen
Solution Approach 1:
The patent changes the chemical composition parameters by using titanium dioxide in nanometric form (1-100 nm) and combining it with soluble silicon at specific ratios (1:1 to 10:1), transforming conventional chemical inputs into a photocatalytic system that activates under UV light to produce hydroxyl radicals for pest control without environmental contamination
Solution Approach 2:
The patent creates a composite material system combining titanium dioxide photocatalyst with soluble silicon, where TiO2 provides photocatalytic biocidal activity under UV irradiation and silicon provides systemic plant resistance enhancement, achieving both productivity improvement and environmental safety
2Reliability
If multiple specific chemical treatments are applied to protect crops from various pests and diseases, then crop protection effectiveness is improved, but the complexity of agricultural operations worsens
Solution Approach 1:
The patent creates a universal composition that simultaneously protects against multiple pest types (insects, mites, fungi, bacteria) and provides systemic plant resistance, replacing the need for multiple separate chemical treatments with a single multi-functional photocatalytic formulation applied at 1:100 to 1:500 dilution
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 composition effectively kills microorganisms and arthropods upon exposure to light, reducing the need for multiple chemical treatments, minimizing environmental harm, and promoting healthier crop growth while being safer for farmers and consumers.
Implementation Method 1
the function of the TiO 2 is to protect from the outside by producing, on being irradiated, hydroxyl and hydroperoxyl radicals which destroy the cell structures of microorganisms and arthropods that attempt to parasitise said plant
Implementation Method 2
The hydroxyl radical is the second species in oxidising power after fluorine (F 2 ) and can damage many macromolecules, particularly lipids and proteins
