Engineering Contradiction Analysis
1Productivity
If traditional linear oxygen-enriched injection methods are used, then the control system is simple and easy to operate, but the reaction effect is suboptimal and smelting efficiency is limited
Solution Approach 1:
The patent applies dynamics principle by implementing non-linear time-varying control of oxygen injection parameters. The oxygen flow rate and injection timing are dynamically adjusted based on real-time molten pool state detection, creating a dynamic control system that adapts to changing conditions during smelting, thereby improving reaction efficiency without requiring overly complex static control mechanisms.
Solution Approach 2:
The patent implements feedback control by using sensors to detect the state of the molten pool and using this information to adjust oxygen injection parameters. The detection unit monitors temperature, flow rate, and other parameters, and the control unit uses this feedback to optimize the oxygen enrichment injection process, achieving improved productivity through a manageable level of system complexity.
2Reliability
If non-linear oxygen-enriched injection methods are implemented to induce chaos in the molten pool, then the reaction effect is optimized, but the difficulty of parameter selection and motor control increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing the non-linear control algorithm and parameter ranges before the smelting process begins. The system pre-calculates optimal oxygen injection parameters based on expected molten pool conditions, and operators only need to select from pre-defined parameter sets rather than adjusting complex parameters in real-time, thus maintaining ease of operation while achieving optimized reaction effects.
Solution Approach 2:
The patent implements self-service through automated detection and control systems that autonomously adjust oxygen injection parameters based on real-time molten pool state. The system self-regulates the non-linear parameters without requiring manual intervention for complex parameter selection, making the process reliable and easy to operate simultaneously.
3Productivity
If chaotic mapping is used to control gas injection volume and fan blade speed, then the molten pool reaches optimal chaotic state, but the control algorithm complexity increases
Solution Approach 1:
The patent replaces complex mechanical control systems with computational chaotic mapping algorithms. Instead of using complex mechanical mechanisms to achieve chaotic flow patterns in the molten pool, the system uses software-based chaotic mapping to calculate optimal gas injection volumes and fan blade speeds, reducing mechanical complexity while maintaining the desired chaotic state for improved smelting efficiency.
Solution Approach 2:
The patent applies parameter changes by using chaotic mapping to dynamically adjust key parameters such as gas injection volume, oxygen flow rate, and fan blade rotational speed. The chaotic mapping transforms simple input parameters into complex time-varying control parameters, achieving optimal molten pool chaos with relatively simple input parameter specification, thus improving productivity without proportionally increasing control algorithm complexity.

Implementation Method 3
when a mixed state in the molten pool reaches chaos, the reaction effect is optimal, and the non-linear injection method is an excellent means to induce chaos in the molten pool
Implementation Method 4
