Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional powder production methods are used, then production costs increase and efficiency decreases, but the system lacks real-time feedback and control over compositional content
Solution Approach 1:
The patent implements real-time feedback by measuring the compositional content of produced powder and waste gas, comparing it to target values, and using this information to adjust feeding rates of primary and secondary materials. This closed-loop control system enables dynamic optimization of production efficiency while maintaining precise compositional control.
Solution Approach 2:
The system performs self-adjustment by automatically modifying its own operating parameters (feeding rates) based on real-time measurements and comparisons. The control unit autonomously optimizes the production process without external intervention, improving efficiency while managing system complexity through self-regulation.
2Manufacturing precision
If multiple compositional proportions are used to achieve user-determined elemental content, then production costs increase, but the system lacks precision in controlling powder composition
Solution Approach 1:
Real-time measurement of powder compositional content provides feedback to the control unit, which adjusts feeding rates to achieve target elemental content. This eliminates the need for multiple pre-defined compositional proportions, reducing production costs while maintaining precise compositional control through dynamic adjustment.
Solution Approach 2:
The system dynamically changes operating parameters (feeding rates of primary and secondary materials) based on real-time measurements to achieve the desired compositional content. This continuous parameter adjustment enables precise control without requiring multiple fixed compositional formulations, reducing production complexity and cost.
3Manufacturing precision
If real-time monitoring and adjustment of elemental content is implemented, then production efficiency and control are enhanced, but the system complexity increases
Solution Approach 1:
The patent implements feedback control by measuring elemental content in real-time and using this information to adjust feeding rates. This systematic approach enhances manufacturing precision while managing complexity through structured measurement-comparison-adjustment cycles.
Solution Approach 2:
The control unit autonomously manages the complexity of real-time monitoring and adjustment by self-regulating feeding rates based on measurements. This self-service capability enhances precision while containing system complexity through automated decision-making algorithms.
4Ease of operation
If a closed system with feedback control is implemented, then user control and efficiency are enhanced, but the device complexity and initial investment increase
Solution Approach 1:
The closed system implements feedback control that provides users with real-time information about powder compositional content and automatic adjustment capabilities. This enhances user control over the production process while managing complexity through automated control mechanisms that reduce the need for manual intervention.
Solution Approach 2:
The system's self-regulating capabilities reduce the operational burden on users by automatically adjusting feeding rates based on real-time measurements. This self-service feature enhances ease of operation while containing complexity through autonomous control algorithms.
