Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual communication setting is performed for each process data item, then communication accuracy is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent segments process data into multiple groups based on their usage patterns in applications. Each group can be independently configured and transmitted, allowing fine-grained control over communication settings while reducing overall complexity. The grouping unit divides the large set of process data into smaller manageable groups.
Solution Approach 2:
The patent performs preliminary grouping and classification of process data before actual communication occurs. The grouping unit pre-organizes process data into groups based on application requirements, and the generation unit pre-generates communication settings based on these groups, reducing the complexity of real-time configuration.
2Adaptability or versatility
If all process data is transmitted to the information processing device, then adaptability is improved, but processing load and communication efficiency worsen
Solution Approach 1:
The patent applies local quality by transmitting different sets of process data to different information processing devices based on their specific application requirements. Each device receives only the process data groups relevant to its function, optimizing communication efficiency while maintaining adaptability to diverse application needs.
Solution Approach 2:
The patent segments the complete set of process data into multiple groups, allowing selective transmission to information processing devices. This enables each device to receive only the necessary data subsets, reducing communication load while maintaining the ability to support various applications through different group combinations.
3Ease of operation
If communication setting is automatically generated, then ease of operation is improved, but manufacturing precision and control over data transmission worsen
Solution Approach 1:
The patent incorporates feedback mechanisms where the grouping unit and generation unit use information about application requirements and process data characteristics to automatically generate appropriate communication settings. The system feedbacks on the grouping results and adjusts the generated communication settings to ensure precise control over data transmission while maintaining ease of operation.
Data Source
AI summary
A control system includes a control device, an information processing device, a grouper, and a generator. The control device executes a control program controlling a control target while managing process data of the control program. The control device transmits one or more types of data sets storing a part of the process data according to a communication setting. The information processing device executes one or more applications using the process data by using the one or more types of data sets. The grouper allocates the process data designated to be used in the one or more applications to one or more groups. The generator generates the communication setting for the control device such that the process data allocated to the group are stored in one data set and transmitted for each of the groups grouped by the grouper according to an allocation result.
