Solution Overview
Problem
Current antimicrobial materials for surfaces, such as kitchen sinks and shower trays, are costly due to the use of expensive antimicrobial agents like zinc oxide core particles, and there is a need for improved hygiene in areas prone to bacterial and viral contamination.
Innovation Solution
A heat-curable casting compound incorporating essential oils, such as lemongrass, tea tree, or cinnamon oil, which provides antibacterial and antimicrobial properties, ensuring that bacteria and viruses cannot multiply or survive on the surface, thereby enhancing hygiene without the need for additional cleaning agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expensive antimicrobial agents like zinc oxide core particles are used, then antimicrobial activity is improved, but production cost increases
Solution Approach 1:
The patent changes the chemical composition parameter from expensive inorganic antimicrobial agents (zinc oxide, silver nitrate) to essential oils with natural antimicrobial properties. This parameter substitution maintains the antimicrobial function while significantly reducing material costs and simplifying the manufacturing process.
Solution Approach 2:
The patent replaces expensive, complex inorganic antimicrobial particles with more economical essential oil formulations. While essential oils may have different stability characteristics, they provide cost-effective antimicrobial protection when properly incorporated into the casting compound matrix.
2Reliability
If essential oils are incorporated into the casting compound, then antimicrobial properties are improved, but the essential oil may evaporate or lose effectiveness during thermal processing
Solution Approach 1:
The patent creates a composite material system where essential oils are incorporated into a polymeric binder matrix along with filler particles. This composite structure protects the essential oils during thermal processing, allowing them to maintain their antimicrobial properties without evaporating or degrading, as the polymer matrix acts as a stabilizing medium.
Solution Approach 2:
The polymeric binder serves as an intermediary medium that protects the essential oils during the casting and thermal processing stages. The binder encapsulates or dissolves the essential oils, preventing their evaporation while allowing them to be uniformly distributed throughout the final molded product, which then provides the antimicrobial function.
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 essential oil-based casting compound effectively reduces bacterial and viral contamination on surfaces, providing a self-cleaning property that maintains antimicrobial efficacy even after thermal processing, improving hygiene in kitchens and bathrooms with excellent mechanical properties and reduced environmental impact.
Implementation Method 1
the casting compound contains at least one essential oil... which gives the casting compound and also the molded object made from it an at least antibacterial, but in particular also an antimicrobial property
Implementation Method 2
the casting compound is placed in a mold and heated to an elevated temperature to polymerize the binder matrix there held for a certain time and then cooled
Implementation Method 3
Surprisingly, it turned out that the essential oil neither evaporates nor changes or loses its antibacterial or antimicrobial properties during the temperature change
