Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If dielectric barrier discharge is applied to generate electrical charge between electrodes, then the DBD system achieves its intended function, but the dielectric barriers heat up and degrade
Solution Approach 1:
The patent recycles the hot process fluid exiting the DBD reactor, which contains thermal energy, and uses it as the cooling medium for the dielectric barriers. This converts the harmful thermal energy that would otherwise be wasted into a beneficial cooling resource, maintaining dielectric barriers at optimal temperatures while improving overall system efficiency
2Temperature
If external cooling systems are added to manage heat in dielectric barriers, then temperature control is improved, but device complexity increases
Solution Approach 1:
The patent integrates the cooling function directly into the existing process fluid circulation system. The diffuser system that distributes process fluid into the reactor is combined with cooling channels that direct fluid to the dielectric barriers, eliminating the need for separate cooling infrastructure and reducing overall system complexity
Solution Approach 2:
The process fluid serves dual functions: it acts as both the reaction medium in the DBD reactor and the cooling medium for the dielectric barriers. This multi-functionality eliminates the need for dedicated cooling systems, simplifying the overall device architecture while maintaining effective temperature control
3Temperature
If process fluid is recirculated for cooling dielectric barriers, then temperature management is improved, but fluid flow requirements increase
Solution Approach 1:
The patent implements a continuous recirculation system where process fluid is constantly circulated between the DBD reactor and the cooling channels. This continuous circulation ensures sustained cooling effectiveness and efficient heat removal, allowing for lower overall fluid flow rates compared to single-pass systems while maintaining optimal dielectric barrier temperatures
