Engineering Contradiction Analysis
1Manufacturing precision
If the control system is continuously updated and individual systems are customized to specific customers, then the functionality and quality of the manufacturing system is improved, but the effort and complexity required to maintain the system increases considerably
Solution Approach 1:
The patent implements a dynamic functionality activation mechanism where software components can be selectively activated or deactivated based on current manufacturing requirements. The control device can temporarily activate alternative functionalities to meet specific quality criteria without permanently modifying the system configuration, thereby maintaining flexibility while reducing maintenance complexity.
Solution Approach 2:
The system changes the activation state of software functionalities as a parameter to adapt to different manufacturing needs. By controlling which functionalities are active at any given time, the system can optimize for specific quality criteria without requiring permanent system reconfiguration or complex integrations between CAD, CAM, and post-processor systems.
2Manufacturing precision
If alternative functionalities are activated to achieve higher quality, then manufacturing quality is improved, but the system requires complex data exchanges and external databases
Solution Approach 1:
The patent merges the functionality checking and activation capabilities directly into the control device. Instead of requiring external databases or complex data exchanges between separate systems, the control device independently determines whether alternative functionalities should be activated based on the current manufacturing context and quality requirements.
Solution Approach 2:
The control device performs self-service by autonomously checking for and activating alternative functionalities without requiring complex external data exchanges. The system uses its own internal resources and decision-making capabilities to optimize manufacturing quality, eliminating the need for elaborate integrations with external systems.
3Productivity
If the control device checks for and activates alternative functionalities, then manufacturing speed and quality are improved, but the control device requires additional processing time and resources
Solution Approach 1:
The control device performs preliminary checks to determine whether alternative functionalities are available and appropriate before activation. By assessing the current manufacturing context and quality requirements in advance, the system can make quick decisions about functionality activation without requiring extensive processing time during actual manufacturing operations.

AI summary
The problem addressed by the invention is the improvement of the quality of production systems. This problem is solved by a production system having a production machine (1) and a control device (2) for generating specific control commands for the production machine on the basis of production data. The control device (2) has an analysis apparatus (7) which is designed to decide, based on a specified quality criterion, whether an activated functionality, which is already integrated in the control device (2), is used to translate the production data into the specific control commands or an alternative functionality, which is provided in a database (8) outside of the control device (2) or in unactivated form in the control device (2), wherein the control device (2) is designed to save a control file for the alternative functionality and to provide said control file for the translation, and wherein the control device (2) is designed to only temporarily provide the alternative functionality.
