Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If combustion-based treatment is used, then decomposition efficiency is improved, but energy consumption increases and greenhouse gas emissions occur
Solution Approach 1:
The patent replaces the combustion-based thermal system with a microwave-based electromagnetic heating system. The microwave generator produces electromagnetic radiation that is converted to thermal energy by the susceptor, achieving decomposition without combustion. This substitution eliminates fuel requirements and greenhouse gas emissions while maintaining high decomposition efficiency through direct electromagnetic-to-thermal energy conversion.
Solution Approach 2:
The patent changes the heating mechanism from external combustion heating to internal microwave-induced heating. By introducing a susceptor material that absorbs microwave radiation and converts it to heat, the system achieves rapid temperature rise to decomposition conditions without the need for continuous fuel combustion, thereby reducing energy consumption while maintaining productivity.
2Productivity
If plasma-based treatment is used, then decomposition efficiency is improved, but device complexity and procurement cost increase
Solution Approach 1:
The patent replaces the complex plasma generation system with a simpler microwave heating system. Instead of requiring sophisticated electrical configurations to generate and control plasma, the system uses a microwave generator coupled with a susceptor to achieve thermal decomposition. This substitution dramatically reduces device complexity while maintaining effective pollutant decomposition.
3Productivity
If plasma-based treatment is used, then decomposition efficiency is improved, but electromagnetic interference issues arise
Solution Approach 1:
The patent extracts the harmful electromagnetic interference component from the treatment system by replacing plasma generation with microwave heating. The susceptor-based microwave system confines electromagnetic energy to thermal conversion within the reaction chamber, eliminating the broad-spectrum electromagnetic interference characteristic of plasma systems while preserving decomposition efficiency.
4Productivity
If combustion-based treatment is used, then decomposition efficiency is improved, but equipment size increases
Solution Approach 1:
The patent replaces the large-scale combustion equipment with a compact microwave heating system. The microwave generator and susceptor configuration enables high-temperature decomposition in a much smaller volume, eliminating the need for large combustion chambers and associated fuel handling infrastructure, thereby reducing overall equipment size while maintaining decomposition efficiency.
