Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hydraulic cylinders are used to drive press devices, then the structure is simple and easy to implement, but accurate pressure control and force control cannot be performed
Solution Approach 1:
The patent replaces hydraulic cylinders with servomotors to drive the press devices. This substitution enables precise control of pressing force and position through electronic feedback mechanisms, resolving the contradiction by achieving accurate pressure control while maintaining reasonable system complexity through modern electromechanical technology.
Solution Approach 2:
The patent implements feedback control systems with sensors that monitor pressing force, position, and velocity in real-time. This feedback mechanism allows the control system to adjust pressing parameters dynamically, achieving accurate pressure and force control that was not possible with simple hydraulic systems.
2Manufacturing precision
If hydraulic cylinders are used for press devices, then the implementation is straightforward, but accurate position control and speed control are difficult to achieve
Solution Approach 1:
The patent replaces hydraulic cylinders with servomotors that provide precise positional and velocity control through closed-loop feedback. This substitution enables accurate position control during the pressing process while using modern electromechanical systems that are comparable in complexity to hydraulic systems.
Solution Approach 2:
The patent employs dynamic control capabilities of servomotors to adjust pressing speed and position in real-time during the molding process. This dynamic control allows for optimized pressing curves and precise positioning that static hydraulic systems cannot achieve.
3Manufacturing precision
If excessive pressurization occurs in press devices, then the molding process is simplified, but the quality such as plate thickness cannot be stabilized
Solution Approach 1:
The patent uses feedback control with sensors to monitor pressing force and position, preventing excessive pressurization. The control system continuously adjusts pressing parameters to maintain optimal conditions, ensuring uniform plate thickness and preventing defects caused by over-pressurization.
Solution Approach 2:
The patent implements preliminary control measures through pre-programmed pressing curves and force limits that prevent excessive pressurization before it occurs. The system is designed with built-in constraints and monitoring that actively prevent harmful pressurization levels.
