Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing enamel compositions for cooking appliances require high cleaning temperatures and often fail to completely remove oil contaminants like chicken oil, which contain unsaturated fatty acids, due to their poor durability and high cost.
Innovation Solution
An enamel composition comprising a base glass frit and a catalytic glass frit with specific metal oxide components, allowing for easy cleaning at room temperature and improved durability by forming a gap between contaminants and the coating surface, thereby facilitating the removal of oil contaminants without high temperature soaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a large amount of catalytic oxide is used to facilitate cleaning, then cleaning performance is improved, but durability and chemical resistance are degraded
Solution Approach 1:
The patent changes the chemical composition parameters of the enamel coating by incorporating specific metal oxides (manganese oxide 0.1-5 wt%, zinc oxide 1-10 wt%, boron oxide 5-20 wt%) in controlled amounts. This compositional adjustment enables the coating to achieve effective cleaning performance at lower temperatures (60-90°C) while maintaining durability and chemical resistance, resolving the contradiction between cleaning effectiveness and coating longevity.
Solution Approach 2:
The patent creates a composite enamel material combining multiple metal oxides with the base enamel matrix. This composite structure synergistically enhances cleaning performance through catalytic activity of metal oxides while the enamel matrix preserves durability and chemical resistance, effectively balancing both requirements.
2Ease of operation
If expensive raw materials are used to improve cleaning performance, then cleaning effectiveness is enhanced, but manufacturing cost increases
Solution Approach 1:
The patent replaces expensive raw materials with cost-effective metal oxide combinations (manganese oxide, zinc oxide, boron oxide) that can be sourced at lower costs. These materials are applied in optimized quantities to achieve the desired cleaning performance without excessive spending, making the enamel coating more economically viable for mass production.
Solution Approach 2:
The patent optimizes the concentration parameters of metal oxide additives to achieve the minimum effective amount needed for catalytic cleaning action. By precisely controlling the weight percentages (manganese oxide 0.1-5 wt%, zinc oxide 1-10 wt%, boron oxide 5-20 wt%), the formulation achieves cost efficiency while maintaining cleaning effectiveness.
3Productivity
If high cleaning temperature is applied to remove oil contaminants, then removal efficiency is improved, but energy consumption and processing time increase
Solution Approach 1:
The patent incorporates metal oxides (particularly manganese oxide and zinc oxide) that act as catalysts to accelerate the oxidation and decomposition of organic contaminants at lower temperatures. This catalytic action enables effective breakdown of oil contaminants without requiring high thermal energy input, thus reducing energy consumption and processing time while maintaining high removal efficiency.
Solution Approach 2:
The patent changes the operating temperature parameter from conventional high temperatures to a lower range (60-90°C) by introducing catalytic metal oxides. This temperature reduction significantly decreases energy consumption and processing time while the catalytic activity of metal oxides compensates for the lower thermal energy, maintaining effective contaminant removal.
