Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a plasma torch is used for heating and melting target material in a plasma furnace, then the target material can be melted and processed, but the operation of the plasma torch may be limited depending on the structure of the furnace and the generated plasma cannot maintain uniform heat in the furnace
Solution Approach 1:
The invention divides the single plasma torch into multiple plasma torches (at least two) arranged around the furnace. This segmentation allows each torch to contribute to heating different zones, collectively achieving uniform heat distribution throughout the furnace while maintaining operational flexibility.
Solution Approach 2:
Multiple plasma torches are combined to work simultaneously in the furnace. Their collective heat output creates uniform temperature distribution, and their coordinated operation overcomes the limitations of a single torch regarding operational flexibility and heat uniformity.
2Use of energy by moving object
If a preheating torch is added to preheat target material, then sufficient heat can be transferred into the furnace, but the device complexity increases
Solution Approach 1:
The multiple plasma torches perform dual functions: they can operate individually or in combination, serving both as preheating sources and as primary melting sources. This eliminates the need for separate preheating and melting torches, reducing overall system complexity while maintaining efficient heat transfer.
Solution Approach 2:
The preheating and melting functions are merged into a single multi-torch system. The torches can be configured to provide both preheating and melting capabilities simultaneously, eliminating the need for additional dedicated preheating equipment.
3Loss of energy
If a large scale plasma torch is used in a large sized furnace, then heat loss in the furnace can be considered, but the thermal efficiency and operation of the torch deteriorates
Solution Approach 1:
Instead of using one large plasma torch, the invention uses multiple smaller plasma torches distributed around the furnace. This segmentation maintains better thermal efficiency for each individual torch while collectively compensating for heat loss in the large furnace volume through distributed heating.
Solution Approach 2:
Multiple plasma torches are positioned at different locations around the furnace to provide localized heating zones. This ensures efficient energy utilization in each local region while collectively addressing the overall heat loss in the large furnace, avoiding the inefficiencies of a single large torch.
4Temperature
If the upper surface of the melting chamber is horizontal, then the structure is simple, but the plasma torch cannot maintain uniform heat distribution
Solution Approach 1:
The invention introduces an inclined upper surface instead of a horizontal one. This asymmetric geometry, when combined with multiple plasma torches positioned around the furnace, enables better heat distribution by allowing molten material to flow and redistribute heat more uniformly throughout the melting chamber.
