Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate controllers are used for each subsystem, then each subsystem can be independently controlled, but the device complexity and number of components increases
Solution Approach 1:
Multiple subsystem controllers are merged into a single universal communication node that can interface with multiple sensors from different subsystems. The universal communication node consolidates the functionality of separate controllers while maintaining the ability to independently manage multiple sensor inputs through a unified architecture.
Solution Approach 2:
A universal communication node is designed to perform multiple functions by interfacing with sensors from various subsystems through a single device. This multi-functional approach eliminates the need for dedicated separate controllers for each subsystem while preserving subsystem independence through software-based sensor identification and management.
2Adaptability or versatility
If multiple separate controllers are used, then each subsystem can be managed independently, but the system configuration becomes more complex
Solution Approach 1:
The universal communication node automatically identifies sensors and determines their associated subsystems without requiring complex manual configuration. The system performs self-service by autonomously mapping sensors to subsystems and establishing communication parameters, thereby simplifying the configuration process while maintaining independent subsystem management capabilities.
3Reliability
If sensors are connected to separate independent controllers, then each sensor can be individually monitored, but the communication efficiency to central controller decreases
Solution Approach 1:
Multiple sensor communication channels are merged into a single universal communication node that consolidates data from multiple sensors before transmitting to the central controller. This merging maintains reliable individual sensor monitoring while improving communication efficiency by reducing the number of separate communication paths required.
