Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seed surface compositions using diazo compounds for coloration have ecological disadvantages due to potential genotoxicity and carcinogenicity concerns, and they lack versatility in color depth and amount, posing challenges for safe use in food and feed crops.
Innovation Solution
A seed surface composition using a compound according to formula (I), where R1 and R2 are independently hydrogen, C1-C4 alkyl, or halogenated C1-C4 alkyl, and R3 and R4 are phenyl, alkylphenyl, or halogenated phenyl, excluding diazo compounds, which provides improved hiding power, uniform coloration, and faster drying, even at half the load compared to diazo-based compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If diazo compounds are used for seed surface coloration, then color depth and versatility are achieved, but ecological safety deteriorates due to potential genotoxicity and carcinogenicity
Solution Approach 1:
The patent extracts and removes the harmful diazo compound component from the seed surface composition while retaining the essential coloration function through alternative non-diazo pigments. This extraction eliminates the genotoxic and carcinogenic risks associated with diazo compounds while maintaining the color marking capability needed for seed identification and safety.
Solution Approach 2:
The patent employs alternative pigments that, while potentially having different persistence characteristics than diazo compounds, provide sufficient coloration for the intended use period without posing ecological risks. These alternative colorants achieve the necessary color depth and versatility for seed marking without the long-term environmental harm of diazo compounds.
2Ease of manufacture
If diazo compounds are used for seed surface coloration, then coloration function is achieved, but material efficiency deteriorates due to higher required amounts
Solution Approach 1:
The patent changes the chemical parameters of the pigment components by substituting diazo compounds with alternative pigments that have different color intensity and coverage characteristics. This parameter change allows for reduced material usage while achieving equivalent or superior coloration effects, improving material efficiency without compromising the coloration function.
3Object-affected harmful factors
If non-diazo compounds are used for seed surface coloration, then ecological safety is improved, but color depth and hiding power deteriorate
Solution Approach 1:
The patent employs composite pigment formulations combining multiple non-diazo pigment types to achieve the desired color depth and hiding power. By creating composite material systems with complementary properties, the formulation compensates for the individually lower performance of single non-diazo pigments, achieving both ecological safety and adequate coloration quality.
Solution Approach 2:
The patent develops a versatile non-diazo pigment system that can achieve multiple functions including adequate color depth, uniform coloration, and ecological safety within a single composition. This multi-functional approach eliminates the need to compromise on color performance when prioritizing ecological safety.
4Object-affected harmful factors
If non-diazo compounds are used for seed surface coloration, then ecological safety is improved, but drying characteristics deteriorate
Solution Approach 1:
The patent adjusts the physical and chemical parameters of the non-diazo pigment formulation, including particle size distribution, surface properties, and compatibility with carriers, to optimize drying characteristics. These parameter changes enable the ecologically safe non-diazo composition to achieve rapid drying comparable to or better than traditional diazo-based formulations.
