Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If rubber powder is directly conveyed to the thermal reaction device for high-temperature treatment, then the desulfurization and plasticization process can be performed, but significant thermal loss occurs reducing efficiency and device longevity
Solution Approach 1:
The patent applies preliminary action by introducing a preheating section before the thermal reaction device. Rubber powder is preheated in this separate section before entering the main high-temperature treatment zone, which reduces the thermal shock to the device and minimizes energy loss during the heating process.
Solution Approach 2:
The thermal processing system is segmented into distinct sections: a preheating section and a thermal reaction section. This segmentation allows for gradual temperature increase and reduces thermal stress on the equipment, thereby reducing energy loss and improving efficiency.
2Productivity
If rubber powder is directly put into the thermal reaction device, then the processing can proceed, but the temperature in the device increases immediately causing greater loss
Solution Approach 1:
The preheating section performs preliminary heating of rubber powder before it enters the thermal reaction device. This preliminary action maintains processing efficiency while avoiding immediate temperature spikes that would cause energy loss and device damage.
