Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cooking apparatuses require high-temperature cleaning methods that are energy-intensive and pose risks to users, and existing cleaning methods are ineffective for heavy contamination, especially for grease and carbonized stains, which often require repeated high-temperature processes and additional catalytic liners.
Innovation Solution
An interior material for cooking apparatuses featuring a coated layer with a silicon backbone and fluorine functional group, applied to a base material such as metal or glass, which provides improved heat-resisting and anti-contaminating properties, allowing for easy cleaning at lower temperatures and reducing contaminant adherence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-temperature cleaning methods (500°C or more) are used to remove contaminants and grease spots, then cleaning effectiveness is improved, but energy consumption increases and user safety risks increase
Solution Approach 1:
The invention changes the surface energy parameter of the coating material from high (enamel) to low (silicon backbone with fluorine functional group) to enable effective cleaning at lower temperatures. This parameter change allows contaminants to be removed at 400°C or below while maintaining cleaning effectiveness, thereby reducing energy consumption and safety risks associated with high-temperature cleaning.
Solution Approach 2:
The invention uses a composite coating material comprising a silicon backbone and fluorine functional group, combining the heat resistance of silicon-based materials with the low surface energy and anti-staining properties of fluorine compounds. This composite material enables effective cleaning at lower temperatures while maintaining durability and resistance to high temperatures during cooking.
2Reliability
If enamel coating is applied to interior surfaces for protection and antibacterial effect, then surface protection is improved, but contaminant removal becomes difficult when contaminants are fixed on the enamel surface during heating
Solution Approach 1:
The invention changes the surface energy parameter of the coating from high (enamel) to low (silicon backbone with fluorine functional group). This parameter change prevents contaminants from adhering strongly to the surface, making them easy to remove even after heating, while the coating maintains its protective function and heat resistance.
Solution Approach 2:
The coating provides different properties at different levels: it maintains heat resistance and protective functions during cooking, but provides low surface energy and anti-adhesion properties during cleaning. This local quality differentiation allows the same coating to excel at both protection and ease of cleaning.
3Reliability
If repeated high-temperature cleaning processes are performed to remove accumulated grease and carbonized stains, then cleaning effectiveness is improved, but energy loss increases and user risks increase
Solution Approach 1:
The low surface energy coating performs preliminary anti-adhesion action during cooking, preventing contaminants from strongly adhering to the surface. This preliminary action eliminates the need for repeated high-temperature cleaning processes, as contaminants can be removed easily in a single low-temperature cleaning cycle, thereby reducing energy loss.
