Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional electric heating furnace or electromagnetic induction heating melting furnace is used, then heating function is provided, but heating is uneven and simultaneous processing of multiple batches is difficult
Solution Approach 1:
The heating chamber is divided into multiple independent heating zones with separate crucibles, each capable of independent temperature control. This allows multiple batches of materials to be processed simultaneously while maintaining uniform heating in each zone through dedicated microwave sources and temperature control systems.
Solution Approach 2:
The patent employs a rotating mechanism that dynamically adjusts the position of crucibles within the heating chamber, ensuring uniform exposure to microwave fields. The rotation system allows samples to move through different heating zones, achieving homogeneous heating across all batches while maintaining high productivity.
2Measurement precision
If equipment for temperature acquisition of materials in different crucibles is used, then temperature data can be obtained, but equipment complexity increases and operability deteriorates
Solution Approach 1:
The patent employs a universal temperature acquisition system where a single integrated device can measure temperatures of multiple crucibles simultaneously. The system uses a rotating measurement mechanism that sequentially accesses all crucibles, providing multi-point temperature data through one unified instrument rather than requiring separate sensors for each crucible.
Solution Approach 2:
The temperature acquisition system uses optical or electromagnetic field-based measurement methods that create virtual copies of temperature data from multiple locations. This allows remote, non-contact temperature sensing of all crucibles through a single measurement point, reducing physical equipment complexity while maintaining comprehensive temperature monitoring capability.
3Productivity
If microwave-based heating is used, then high-throughput preparation is achieved, but temperature acquisition equipment becomes complicated
Solution Approach 1:
The microwave heating system incorporates automatic temperature monitoring and control where the system self-regulates heating parameters based on real-time temperature feedback from all crucibles. The integrated control system automatically adjusts microwave power distribution to maintain optimal temperatures, eliminating the need for manual temperature measurement and adjustment operations.
Solution Approach 2:
The patent implements a closed-loop feedback control system where temperature data from all crucibles is continuously monitored and fed back to the microwave control system. This automatic feedback mechanism adjusts heating parameters in real-time to maintain uniform temperatures across all batches, simplifying operation while enabling high-throughput processing with precise temperature control.
