Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional fertilizers like ammonium nitrate are used, then nitrogen supply is provided, but cost and environmental risks increase
Solution Approach 1:
The system enables on-site production of reactive nitrogen species directly at the application location, eliminating the need for transportation and storage of traditional fertilizers. The plasma reactor generates RNS from atmospheric nitrogen and oxygen, making the system self-sufficient and reducing environmental exposure risks associated with conventional fertilizer handling and transport
Solution Approach 2:
The invention changes the chemical form of nitrogen delivery from stable ammonium nitrate to reactive nitrogen species generated through plasma discharge. This parameter change in nitrogen chemistry enables controlled on-site generation, reducing the need for bulk storage and transportation while providing targeted nitrogen supply to crops
2Productivity
If plasma reactors are used to produce RNS, then nitrogen production efficiency improves, but system complexity increases
Solution Approach 1:
The system is divided into modular plasma reactors that can be independently operated and scaled. Each reactor is a self-contained unit with standardized components, allowing the overall system complexity to be managed through modular assembly rather than a single complex integrated system
Solution Approach 2:
The plasma reactor system is designed to perform multiple functions: generating reactive nitrogen species, cooling electrodes, and mixing with solvate. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while maintaining high nitrogen production efficiency
3Quantity of substance
If gas phase RNS are transferred into solvate, then nitrogen concentration increases, but transfer efficiency is low
Solution Approach 1:
The system uses an intermediary injection mechanism that introduces gas phase RNS into a liquid stream, facilitating efficient mass transfer. The injection system creates conditions that enhance the dissolution and transfer of reactive nitrogen species from gas to liquid phase, simultaneously achieving high concentration and efficient transfer
4Productivity
If multiple plasma reactors are integrated, then production scalability improves, but device complexity increases
Solution Approach 1:
The system employs segmented modular reactors that can be independently configured and scaled. Each module is a standardized unit that can be added or removed based on production requirements, enabling scalability without proportionally increasing integration complexity through standardized interfaces and modular architecture
