Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different transmission protocols and file formats are used for each machine tool and system, then each system can operate with its own optimized data format, but the integration of new machine tools or systems requires manual adaptation which increases time and cost
Solution Approach 1:
The patent introduces a data interface device as an intermediary component between the control system and machine tools. This device contains a database with protocol definitions and automatically translates data between different formats, eliminating the need for manual adaptation when integrating new machine tools or systems.
Solution Approach 2:
The system dynamically changes data transmission parameters (protocols, file formats) based on the target machine tool or system. The data interface device automatically selects and applies the appropriate protocol from its database, allowing seamless integration without manual reconfiguration.
2Reliability
If manual adaptation is performed for each new machine tool integration, then custom optimization for each system is possible, but the process becomes cost-intensive and reduces manufacturing flexibility
Solution Approach 1:
The data interface device performs self-service by automatically determining which protocol to use and translating data formats without human intervention. The system queries its internal database and executes the appropriate translation routine, ensuring reliable data transmission while simplifying integration processes.
Solution Approach 2:
The protocol definitions and translation rules are pre-configured in the data interface device's database before actual machine tool integration is needed. This preliminary preparation enables automatic, reliable data transmission from the outset, eliminating the need for manual adaptation during integration.
3Adaptability or versatility
If a heterogeneous machine park with old, foreign and new machines is operated, then manufacturing flexibility is maintained, but data transmission requires multiple different protocols increasing system complexity
Solution Approach 1:
The data interface device is designed as a universal interface that can handle multiple different protocols and data formats simultaneously. It serves as a multi-functional bridge that translates between various protocols, allowing heterogeneous machine parks to operate with a single standardized interface rather than requiring multiple specialized connection systems.
