Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a wedge assembly is used to position stamps in the press, then the press position precision and stability of transverse stamps are improved, but the positioning precision of upper and lower stamps cannot be guaranteed
Solution Approach 1:
The patent applies preliminary action by performing measurement and calibration of the upper and lower stamps before they are installed in the press. The measuring device measures the actual positions of the stamps and calculates correction values in advance, which are then stored in a database. When the press operates, these pre-calculated correction values are used to adjust the positioning, ensuring consistent precision without requiring complex real-time measurement systems in the press itself.
2Manufacturing precision
If manual measurement and calibration of utensils is performed in the press, then positioning precision can be achieved, but setup time is significantly increased
Solution Approach 1:
The patent replaces manual mechanical measurement operations with an automated measuring device that uses optical or laser-based measurement systems. The device automatically measures the positions of multiple stamps, die units, and other utensils, and a control unit automatically processes the measurement data to calculate correction values. This substitution of manual mechanical measurement with automated measurement systems dramatically reduces setup time while maintaining high positioning precision.
Solution Approach 2:
The system performs measurement and calibration operations before the actual pressing production begins. By measuring all utensils in advance and storing correction values in a database, the system eliminates the need for time-consuming manual adjustments during press setup, enabling quick changeovers while maintaining precision.
3Manufacturing precision
If precise positioning of all utensils is ensured, then manufacturing precision and stability are improved, but measurement and calibration complexity increases
Solution Approach 1:
The patent segments the measurement and calibration process into distinct functional modules: a measuring device for capturing position data, a control unit for processing measurements and calculating corrections, and a database for storing correction values. This segmentation allows each module to perform its specific function independently, simplifying the overall system architecture and making the complex measurement and calibration process more manageable and maintainable.

AI summary
In a method for measuring or calibrating utensils, in particular in pressing processes, different dimensions and/or positions of the utensils, such as tools, stamps, die units, chucks or the like, are determined. A measuring device is provided, with which the utensils are placed relative to one another in the press as in the installed state and are displaceable relative to one another at least in the axial direction of the opening in the die unit forming the die and are measured and/or calibrated individually and relative to one another. The pressed parts and workpieces to be produced using a press can thus be manufactured in a highly precise manner, moreover in high numbers using the same utensils.
