Engineering Contradiction Analysis
1Productivity
If catalysts are stacked vertically in a cumulative manner to improve decomposition rate, then decomposition efficiency is improved, but airflow becomes blocked and processing capacity is limited
Solution Approach 1:
The catalyst unit is divided into multiple layers with partitions, creating separate channels for gas flow. This segmentation allows the catalysts to be stacked vertically for improved decomposition efficiency while maintaining smooth airflow through the partitions that guide the gas flow path.
Solution Approach 2:
The patent transitions from a single-layer catalyst arrangement to a multi-layer vertical stacking configuration. By utilizing the vertical dimension and introducing partitions between layers, the system achieves higher decomposition rates while preserving airflow smoothness through the partition-designed flow paths.
2Use of energy by moving object
If heater unit and catalyst unit are separated to improve heat exchange, then heat exchange efficiency is improved, but system complexity and space requirements increase
Solution Approach 1:
The heater unit and catalyst unit are integrated into a single housing structure, reducing system complexity and space requirements. The heater is positioned to directly heat the catalyst unit, maintaining high heat exchange efficiency while eliminating the need for separate, complex heating systems.
Solution Approach 2:
The partition structure serves as an intermediary element that facilitates heat transfer from the heater unit to the catalyst unit while maintaining their integrated configuration. This allows efficient heat exchange without requiring direct contact or complex thermal coupling mechanisms.
3Temperature
If pipe length is increased to transport heated gas to catalyst unit, then gas heating is improved, but heat loss increases and power consumption rises
Solution Approach 1:
The patent eliminates the intermediate pipe transport section by directly positioning the catalyst unit within or adjacent to the heater unit. This extraction of the pipe element from the system reduces heat loss and power consumption while maintaining effective gas heating and catalyst activation.
Solution Approach 2:
The gas is heated directly at the point of introduction into the catalyst unit, eliminating the need for subsequent pipe transport. This preliminary heating action at the source minimizes heat loss that would otherwise occur during pipe transmission.

AI summary
Provided is a catalyst system capable of removing perfluorinated compounds and nitrous oxide. An exhaust gas is heated in two stages through a heat exchange unit and applied to a heater unit. The heater unit generates a flame to heat the exhaust gas to a high temperature. A catalyst unit is directly connected to a heating space of the heater unit so the heated exhaust gas comes into contact with a catalyst, and the perfluorinated compounds and the nitrous oxide are decomposed in the catalyst unit.
