Engineering Contradiction Analysis
1Productivity
If a high power magnetron is used to achieve large gas conversion capacity, then the gas conversion capacity is improved, but the system cost increases rapidly and scalability is reduced
Solution Approach 1:
The system divides the gas conversion function into multiple independent plasma processing units, each with its own magnetron. Instead of using one high-power magnetron, the patent employs multiple lower-power magnetrons (e.g., ten 1kW magnetrons instead of one 10kW magnetron) to achieve the same total conversion capacity. This segmentation reduces the economic cost since the price of multiple smaller magnetrons is much lower than a single high-power magnetron, while maintaining the required gas conversion capacity.
2Productivity
If a high power magnetron is used to achieve large gas conversion capacity, then the gas conversion capacity is improved, but the scalability of the system is reduced
Solution Approach 1:
By segmenting the system into multiple independent plasma processing units, each unit can be independently controlled and scaled. The system can gracefully handle varying amounts of gas conversion capacity by activating or deactivating individual units based on demand, providing excellent scalability that a single high-power magnetron system cannot achieve.
Solution Approach 2:
The system enables dynamic operation where individual plasma processing units can be independently activated or deactivated based on the required gas conversion capacity. This dynamic configuration allows the system to adapt to varying application requirements, providing flexibility and scalability that fixed high-power systems lack.
3Productivity
If a high power magnetron is used to achieve large gas conversion capacity, then the gas conversion capacity is improved, but the system downtime increases when components fail
Solution Approach 1:
The system divides the gas conversion function into multiple independent plasma processing units, each with its own magnetron and plasma applicator. This segmentation ensures that if one unit or component fails, the other units can continue operating independently, preventing complete system shutdown and maintaining gas conversion capacity through the remaining functional units.
Solution Approach 2:
Each plasma processing unit operates as an independent module with localized functionality. When a failure occurs in one unit, only that local module is affected while other modules maintain their operational quality and continue to process gas, ensuring overall system reliability and availability.
4Ease of manufacture
If multiple plasma processing units are used to improve scalability and reduce cost, then the system cost is reduced and scalability is improved, but the device complexity increases
Solution Approach 1:
The system uses multiple identical plasma processing units, each being a self-contained module with magnetron, waveguide, and plasma applicator. This modular segmentation standardizes the components, making the system easier to manufacture and assemble despite having multiple units. The repetitive nature of identical modules reduces overall complexity compared to designing a single complex high-power system.
