Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If legacy approaches are used for deploying and managing Internet-connected devices, then device deployment and management can be achieved, but scalability and security are limited
Solution Approach 1:
The system segments device management into multiple components: device profile service, authentication service, and communication service. Each component handles specific aspects of device management independently, allowing the system to scale by adding or modifying individual segments without affecting the entire system.
Solution Approach 2:
A service server acts as an intermediary between devices and the network, handling authentication, device profiling, and communication routing. This intermediary layer enhances security by centralizing authentication and improves scalability by managing device connections centrally rather than requiring direct peer-to-peer management.
2Reliability
If advanced techniques for secure authentication and scalable communication are implemented, then security and scalability are improved, but system complexity increases
Solution Approach 1:
Devices automatically generate their own profiles and authentication credentials through the device profile service. The system performs self-configuration and self-registration without requiring manual intervention, which reduces operational complexity while maintaining strong security through automated credential management.
Solution Approach 2:
The service server provides multiple functions including authentication, device profiling, communication routing, and session management through a single unified platform. This multi-functional approach consolidates what would otherwise require multiple separate systems, reducing overall system complexity while providing comprehensive security and scalability.
3Quantity of substance
If the system handles large numbers of devices, then device capacity increases, but communication efficiency and management become challenging
Solution Approach 1:
The service server acts as a central mediator that routes communications between devices and external networks. By consolidating communication management through this intermediary, the system can handle large numbers of devices efficiently without requiring each device to manage its own connections, thus maintaining communication efficiency while scaling device capacity.
Solution Approach 2:
The system segments device communications into device-specific profiles and communication channels managed by the service server. This segmentation allows the system to handle numerous devices by organizing their communications into manageable, independently tracked segments rather than requiring monolithic communication management.
