Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional press working machines use simple slide movement without precise control, then the device complexity is reduced, but the manufacturing precision of molded articles deteriorates
Solution Approach 1:
The patent employs position detection means to continuously monitor the actual positions of slides during press working operations. The control system compares detected positions with target positions and adjusts drive forces in real-time to maintain proper horizontal states of slides, ensuring manufacturing precision through closed-loop feedback control
Solution Approach 2:
The patent replaces traditional mechanical linkage-based slide control with an electric drive system that uses motors and position detection. This substitution allows for precise electronic control of slide positions and forces, achieving high manufacturing precision while reducing mechanical complexity through software-based control algorithms
2Productivity
If multiple slides are moved simultaneously during press working, then the productivity is improved, but the risk of collision between slides or structures increases
Solution Approach 1:
The control system continuously detects the positions of multiple slides and compares them with predetermined safe position ranges. When a slide approaches a position that could cause collision, the system automatically adjusts the drive force or stops movement, enabling high-speed simultaneous operation while preventing collisions through real-time monitoring and adaptive control
Solution Approach 2:
The patent implements dynamic control of multiple slides where the control system continuously adapts drive forces based on real-time position feedback. The system can dynamically adjust the speed, position, and force of each slide independently, allowing optimized simultaneous operation that maintains productivity while ensuring collision-free operation through adaptive motion control
3Manufacturing precision
If the slides are not maintained in proper horizontal state during operation, then the ease of operation is improved, but the manufacturing precision of molded articles deteriorates
Solution Approach 1:
The control system automatically maintains slides in proper horizontal states by continuously detecting their positions and autonomously adjusting drive forces without requiring manual intervention. The system self-corrects any deviations from horizontal positioning, ensuring manufacturing precision while maintaining ease of operation through automated control
Solution Approach 2:
Position detection means continuously monitor slide horizontal states and provide feedback to the control system. The control system processes this information and automatically adjusts drive forces to maintain proper horizontal positioning, achieving both manufacturing precision and ease of operation through closed-loop control that eliminates the need for complex manual adjustment
