Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current paints for turf and grass surfaces lack antimicrobial properties, which can lead to the growth of mold and bacteria, particularly in high-traffic or public areas like schools and hospitals, necessitating the need for a paint that maintains sanitation and visibility.
Innovation Solution
A new paint composition utilizing chlorophyll as a main active ingredient, combined with organic acrylic emulsion, water, bactericide, anti-foaming agents, blending agents, bioregulators, cellulose thickener, and chlorophyll pigment, providing antimicrobial protection and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional paints are used on turf surfaces, then visibility and color are maintained, but antimicrobial protection is lacking leading to mold and bacteria growth
Solution Approach 1:
The patent combines conventional paint components (acrylic emulsion, pigments, solvents) with antimicrobial agents (chlorophyll, zinc oxide, copper compounds) into a single integrated composition. This merging allows the paint to simultaneously provide color/visibility and antimicrobial protection, resolving the contradiction between maintaining visibility and preventing microorganism growth.
Solution Approach 2:
The invention uses composite material formulation by integrating multiple functional components: acrylic emulsion for adhesion, pigments for color, and various antimicrobial compounds (chlorophyll 0.1-5%, zinc oxide 1-10%, copper compounds 1-5%). This composite approach creates a paint that delivers both aesthetic and sanitary functions simultaneously.
2Reliability
If antimicrobial agents are added to paint composition, then sanitation is improved, but paint formulation complexity increases
Solution Approach 1:
The patent employs multi-functional ingredients that serve multiple purposes. For example, chlorophyll provides both green coloration and antimicrobial activity; zinc oxide offers UV protection and antimicrobial properties; copper compounds provide both pigment and biocidal effects. This universality reduces formulation complexity by using single additives that accomplish multiple goals.
Solution Approach 2:
The invention optimizes the concentration parameters of antimicrobial agents within specific ranges (chlorophyll 0.1-5%, zinc oxide 1-10%, copper compounds 1-5%) to achieve effective sanitation while maintaining paint performance and minimizing formulation complexity. By establishing optimal parameter ranges, the patent balances efficacy with simplicity.
3Object-affected harmful factors
If natural chlorophyll pigment is used, then environmental safety is improved, but color intensity and durability may be reduced
Solution Approach 1:
The patent creates a composite pigment system combining natural chlorophyll (0.1-5%) with synthetic green pigments and other metal oxide pigments. This composite approach maintains the environmental safety benefits of natural chlorophyll while compensating for its lower color intensity and durability through the addition of more stable synthetic pigments, achieving both ecological and aesthetic requirements.
Solution Approach 2:
The invention merges natural and synthetic pigment systems in a single formulation. The natural chlorophyll provides environmental safety and basic green color, while synthetic green pigments and metal oxides (zinc oxide, copper compounds) enhance color intensity, fastness, and durability. This merging resolves the contradiction between environmental safety and color performance.
