Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current compositions fail to effectively eliminate odors while maintaining stability and incorporating scents, particularly when using silver nanoparticles and borax, due to challenges in combining antimicrobial properties with fragrances.
Innovation Solution
A composition comprising silver nanoparticles, disodium tetraborate decahydrate (borax), and scented essential oil, where silver nanoparticles are created through a colloidal suspension process, and the mixture is stabilized with excess borax and ethanol, allowing for effective odor reduction and antimicrobial action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If silver nanoparticles and borax are combined to eliminate odors through antimicrobial properties, then odor elimination effectiveness is improved, but composition stability deteriorates
Solution Approach 1:
The patent introduces ethanol as an intermediary substance that mediates between the antimicrobial components (silver nanoparticles and borax) and the scented essential oil. The ethanol serves as a co-solvent that stabilizes the mixture of water-based and oil-based components, preventing phase separation while maintaining the antimicrobial effectiveness of the silver nanoparticles and borax combination.
Solution Approach 2:
The patent creates a composite composition that integrates multiple functional components: silver nanoparticles for antimicrobial action, borax for odor neutralization, scented essential oil for fragrance, and ethanol as a stabilizing co-solvent. This composite formulation achieves both odor elimination effectiveness and composition stability through synergistic interaction of its components.
2Object-generated harmful factors
If scented essential oil is incorporated into the composition, then desirable scent is improved, but compatibility with antimicrobial components deteriorates
Solution Approach 1:
Ethanol acts as an intermediary that bridges the incompatible phases of scented essential oil and water-based antimicrobial components. The essential oil dissolves in ethanol, which then distributes the scented molecules throughout the aqueous composition containing silver nanoparticles and borax, achieving both desirable scent and compatibility.
Solution Approach 2:
The patent changes the physical-chemical parameters of the composition by introducing ethanol, which alters the solubility characteristics and allows the hydrophobic scented essential oil to coexist with the hydrophilic antimicrobial components. This parameter change enables the integration of fragrance without compromising antimicrobial effectiveness.
3Adaptability or versatility
If multiple components are combined to achieve both antimicrobial properties and fragrance, then functionality is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated composition: odor elimination through silver nanoparticles and borax, fragrance through scented essential oil, and stability through ethanol. This unified formulation simplifies manufacturing compared to applying multiple separate products, as all components are combined in one mixture that can be prepared and applied together.
