Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual updating of communication units is performed, then communication interfaces can be configured, but updating costs increase and complexity increases
Solution Approach 1:
The system performs self-configuration of communication interfaces through automated manifest generation. The Multi Device Connector Routine automatically reads software cluster manifests, generates updated communication manifests, and configures interfaces without requiring manual intervention, thereby reducing updating complexity while maintaining reliable communication configuration
Solution Approach 2:
The system prepares communication interface configurations in advance by storing software cluster manifests before updates occur. These pre-stored manifests contain all necessary communication interface definitions, enabling rapid automated regeneration and configuration during updates, which reduces both cost and complexity
2Reliability
If manual updating of communication units is performed, then communication interfaces can be configured, but time consumption increases
Solution Approach 1:
The automated Multi Device Connector Routine performs self-service manifest generation and interface configuration, eliminating time-consuming manual steps. The system automatically reads existing manifests, generates updated communication manifests, and configures interfaces programmatically, significantly reducing updating time while ensuring reliable configuration
Solution Approach 2:
Software cluster manifests are prepared and stored in advance before updates are needed. This preliminary preparation allows the automated routine to quickly generate updated communication manifests during updates, reducing the time required for configuration while maintaining reliability
3Adaptability or versatility
If software clusters are updated frequently, then functionality can be improved, but communication unit updating complexity increases
Solution Approach 1:
The system employs self-service automated manifest generation that handles frequent software cluster updates without increasing complexity. The Multi Device Connector Routine automatically processes update requests, reads changed manifests, generates updated communication manifests, and configures interfaces programmatically, enabling frequent updates while maintaining manageable complexity
Solution Approach 2:
Software cluster manifests are prepared in advance with all communication interface definitions. This preliminary preparation enables the system to handle frequent updates efficiently, as the automated routine can quickly process changes without requiring complex manual reconfiguration, thus supporting high adaptability while controlling complexity
