Insect Repellent Surface Coating Formulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insect-transmitted diseases pose a significant threat to human health and economies, particularly in developing countries, due to the inability of existing technologies to effectively repel insects from surfaces, which can harbor and transmit diseases.
Innovation Solution
A surface coating formulation combining synthetic and natural active ingredients, such as permethrin, lemongrass oil, and surfactants, is developed for water-based and solvent-based coatings, wood laminate products, and wallpapers, providing a repellent action that discourages insects from landing or dwelling on treated surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surface coatings are used, then surfaces provide basic protection and aesthetics, but they fail to repel insects effectively, allowing insects to land and transmit diseases
Solution Approach 1:
The patent combines multiple active ingredients (permethrin, cypermethrin, natural extracts) with coating materials to create a composite surface coating that provides both protective and insect-repellent functions, effectively preventing insects from landing on surfaces and reducing disease transmission risk
Solution Approach 2:
The surface coating acts as an intermediary barrier between insects and human environments, using chemically stable active ingredients that repel insects without directly contacting humans, thereby indirectly protecting against disease transmission
2Reliability
If synthetic insect repellent ingredients are used, then repellent effectiveness is improved, but compatibility and stability in various coating compositions may be compromised
Solution Approach 1:
The patent carefully selects and adjusts the chemical parameters of active ingredients (permethrin, cypermethrin) and their concentrations to achieve optimal compatibility and chemical stability within water-based and solvent-based coating compositions while maintaining effective insect repellent properties
Solution Approach 2:
By creating composite formulations that integrate multiple repellent ingredients with coating materials, the patent achieves both high repellent effectiveness and improved chemical stability through synergistic interactions between components
3Adaptability or versatility
If multiple active ingredients are combined in the formulation, then insect repellent spectrum is broadened, but formulation complexity increases
Solution Approach 1:
The patent merges multiple active ingredients (permethrin, cypermethrin, natural extracts) into a single integrated surface coating formulation, combining their repellent effects to broaden the spectrum of protected insects while simplifying application through a unified product
