Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized control panels are used to manage power drive units, then control and coordination is simplified, but system complexity and decision-making time increase linearly
Solution Approach 1:
The system divides the centralized control function into distributed autonomous agents (PDUs). Each PDU operates independently with its own control logic, eliminating the need for a single complex centralized controller. This segmentation reduces overall system complexity while maintaining coordinated operation through local communication.
Solution Approach 2:
Each PDU is designed as an autonomous agent that makes its own decisions based on local conditions and global objectives. The PDUs self-regulate their operations without requiring continuous centralized control, reducing the computational burden on any single controller while maintaining system coordination.
2Stability of the object's composition
If centralized control panels process all decisions, then coordination is maintained, but processing time increases linearly with system size
Solution Approach 1:
Decision-making is segmented from centralized processing to distributed autonomous processing. Each PDU independently processes local decisions and communicates only necessary information to neighboring PDUs, reducing the decision-processing time from O(n) to O(1) per local decision while maintaining coordination through the mesh network.
Solution Approach 2:
The system implements feedback mechanisms where PDUs continuously exchange status information with neighboring PDUs through the mesh network. This allows coordinated decision-making without requiring centralized processing, as each PDU receives feedback from its environment and adjusts its behavior accordingly in real-time.
3Productivity
If specialized software solutions are developed for different implementations, then system functionality is optimized, but software complexity and development requirements increase
Solution Approach 1:
The system employs a universal software architecture where PDUs use standardized communication protocols and autonomous decision-making frameworks that work across different aircraft configurations. This multi-functional design allows the same software platform to serve multiple applications without requiring implementation-specific custom software, reducing development complexity while maintaining optimized functionality.
