Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If correction methods are implemented in positioning systems with manufacturer-specific data management and interfaces, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal correction method that can be applied across different positioning systems regardless of manufacturer-specific architectures. The deviation map and correction values are generated in a manufacturer-neutral format that can interface with various control systems, making the correction functionality universal rather than system-specific.
Solution Approach 2:
The patent introduces an intermediary correction system that sits between the measurement system and the positioning control. The deviation map serves as a mediator that translates physical deviations into correction values without requiring direct integration with manufacturer-specific data management systems, thus reducing complexity while maintaining precision.
2Manufacturing precision
If temperature-dependent corrections are implemented across different positioning systems, then positioning accuracy is improved, but adaptability requirements increase
Solution Approach 1:
The correction method is designed to be universally applicable across different positioning systems by using a standardized deviation map format and correction calculation approach that does not depend on specific system architectures or manufacturer interfaces.
Solution Approach 2:
The patent accounts for temperature-dependent parameter changes in the positioning system by generating correction values based on temperature-compensated deviation maps. The system adapts to temperature variations by selecting appropriate correction values from the deviation map rather than requiring structural adaptations.

AI summary
The method involves detecting systematic deviations (62.1-62.N) of a system geometry in a surrounding condition. Reference deviations characteristic diagrams (82.1-82.3) are generated based on the deviations and the condition and are associated to a positioning system (1). A surrounding condition-dependent characteristic is determined. A correct value is determined for correcting the system based on a preset environment condition, an actual environment condition and the characteristic. The value is considered during processing of a positioning function for correcting the deviations. An independent claim is also included for a device for correcting a positioning system, comprising a sensor unit.
