Engineering Contradiction Analysis
1Ease of manufacture
If a pin-type heating element is used for heating, then the heating structure is simple, but the combustion is incomplete and produces peculiar smell
Solution Approach 1:
The patent changes the heating parameters by using graphene material with superior thermal conductivity and heating efficiency. The graphene heating element operates at optimized temperature and time parameters to achieve complete combustion, eliminating the peculiar smell while maintaining structural simplicity
Solution Approach 2:
The patent employs composite material structure with graphene as the heating element, Teflon as the insulating layer, and ceramic as the protective layer. This composite design achieves complete combustion without smell while providing electrical insulation and structural protection
2Device complexity
If traditional heating methods are used, then the device structure is simple, but the heating efficiency is low and combustion is incomplete
Solution Approach 1:
The patent utilizes graphene's exceptional thermal conductivity parameter to dramatically improve heating efficiency. The graphene heating element rapidly transfers energy to the material, achieving complete combustion in seconds, thereby resolving the contradiction between simple structure and low heating efficiency
Solution Approach 2:
The patent replaces traditional mechanical pin-type heating elements with a graphene-based thermal field system. This substitution enables more efficient energy transfer and complete combustion without significantly increasing device complexity
