Solution Overview
Problem
Conventional enamel compositions for cooking devices require high temperatures for cleaning and struggle to effectively remove oil contaminants like chicken fat, which contains unsaturated fatty acids, making it difficult to clean at room temperature and increasing costs.
Innovation Solution
An enamel composition comprising glass frit and a metal oxide catalyst, specifically unary or binary metal oxides like Bi2O3, TiO2, V2O5, MnO, Fe2O3, CuO, ZnO, WO3, and MoO3, is developed, allowing for easy removal of oil contaminants at room temperature and optimizing cleaning performance at lower costs by mixing 90 wt% glass frit with 2 wt% to 10 wt% metal oxide catalyst.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional enamel composition is used for cleaning, then cleaning can be performed at elevated temperature (60-90°C), but oil contaminants like chicken fat containing unsaturated fatty acids remain difficult to remove
Solution Approach 1:
The patent changes the chemical composition parameters of the enamel by incorporating specific metal oxides (Bi2O3, TiO2, V2O5, MnO, Fe2O3, CuO, ZnO, WO3, MoO3) in controlled amounts (0.1-10 wt%) into the glass frit matrix. This compositional modification enables the enamel to effectively remove unsaturated fatty acid contaminants at room temperature while maintaining its protective functions, resolving the contradiction between cleaning ease and contaminant removal effectiveness.
Solution Approach 2:
The patent creates a composite enamel material by combining glass frit with multiple metal oxide catalysts. This composite structure synergistically enhances the contaminant removal capability, particularly for oil contaminants like chicken fat, while preserving the enamel's durability and thermal properties. The composite material approach allows simultaneous achievement of effective cleaning and reliable contaminant removal.
2Reliability
If high temperature cleaning is applied to remove oil contaminants, then some cleaning effectiveness is achieved, but cleaning costs increase and room temperature cleaning is not enabled
Solution Approach 1:
The patent replaces the thermal energy-based cleaning mechanism with a chemical catalysis mechanism. By incorporating metal oxide catalysts into the enamel composition, the system enables contaminant removal through chemical reactions at room temperature, eliminating the need for high-temperature heating and significantly reducing energy consumption while maintaining effective contaminant removal.
Solution Approach 2:
The patent modifies the chemical composition of the enamel by adding metal oxide catalysts, which changes the operational temperature parameter from elevated (60-90°C or higher) to room temperature. This parameter change enables effective contaminant removal without energy-intensive heating, resolving the contradiction between cleaning effectiveness and energy consumption.
3Reliability
If conventional enamel composition is used, then basic protective function is maintained, but cleaning performance at room temperature is insufficient and costs increase
Solution Approach 1:
The patent optimizes the concentration parameters of metal oxide additives within specific ranges (0.1-10 wt%, preferably 0.5-5 wt%) to achieve enhanced cleaning performance at room temperature. This controlled parameter modification improves manufacturing efficiency and reduces cleaning costs by eliminating high-temperature processing requirements, while maintaining the enamel's protective functions.
Solution Approach 2:
The patent introduces localized catalytic properties into the enamel structure by incorporating metal oxide catalysts at specific concentrations. This creates local active sites for contaminant degradation while preserving the overall protective characteristics of the enamel, enabling cost-effective room temperature cleaning without compromising protective function.
