Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hydraulic cylinders are used for press devices, then the structure is simple and easy to implement, but accurate pressure control and position control cannot be achieved
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, eliminating the control inaccuracies inherent in hydraulic systems while maintaining mechanical functionality.
Solution Approach 2:
The patent implements feedback control systems with sensors that continuously monitor pressing force, position, and temperature. This feedback enables real-time adjustments to maintain precise control parameters, resolving the contradiction between control accuracy and system complexity by making the complexity beneficial through closed-loop control.
2Manufacturing precision
If hydraulic pressure control is used in vacuum laminating device and planar press means, then the system is easier to operate, but accurate pressure control and position control are difficult to achieve
Solution Approach 1:
The patent replaces hydraulic pressure control systems with servomotor-driven mechanical systems in both the vacuum laminating device and planar press means. This substitution enables precise position and pressure control through direct mechanical drive with electronic feedback, eliminating the indirect control characteristics of hydraulic systems.
Solution Approach 2:
The patent employs dynamically controllable servomotor systems that can adjust pressing speed, force, and position in real-time based on feedback signals. This dynamic control capability provides both high precision and ease of operation through programmable control sequences and automatic adjustment features.
3Manufacturing precision
If excessive pressurization occurs in press devices, then the molding process is more aggressive, but the quality such as plate thickness of the final laminate molded article cannot be stabilized
Solution Approach 1:
The patent implements feedback control with force sensors that continuously monitor the pressing force applied to the laminate. When the measured force approaches the target value, the system automatically adjusts to maintain precise force control, preventing excessive pressurization and ensuring stable plate thickness in the final product.
Solution Approach 2:
The patent dynamically adjusts pressing force parameters during the molding process based on real-time feedback. The system modifies force magnitude, application rate, and duration to optimize the molding process, ensuring sufficient pressure for quality molding while preventing excessive force that would compromise plate thickness stability.
