Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cloud desktop technology is used, then computing and storage resources are centralized in data centers, but latency is high and real-time control is not achieved
Solution Approach 1:
The system segments cloud desktop functionality into two parts: virtualization management remains centralized in data centers, while virtual desktop agents are deployed at edge nodes closer to users. This segmentation enables local processing of control operations, reducing latency while maintaining centralized security management.
Solution Approach 2:
Edge nodes serve as intermediaries between data centers and user terminals. They cache virtual desktop images and handle local protocol conversion, reducing the need for frequent cloud round-trips and thereby reducing latency while maintaining data center security.
2Adaptability or versatility
If devices with different communication interfaces and protocols are integrated, then device connectivity is achieved, but system complexity increases
Solution Approach 1:
The virtual desktop agent acts as an intermediary that handles protocol conversion between different communication interfaces (USB, RS232, RS485, Bluetooth, etc.). This centralized conversion approach simplifies the overall system architecture by eliminating the need for each device to have multiple protocol handlers.
Solution Approach 2:
The virtual desktop agent is designed with multi-functionality to handle various communication protocols and device types through a unified interface. This universal approach allows single device to interface with multiple different communication standards without requiring separate integration logic for each protocol.
3Ease of operation
If cloud desktop technology is used, then desktop devices can be simplified to thin clients, but real-time industrial control requirements cannot be met
Solution Approach 1:
The system segments control operations into local actions handled by the virtual desktop agent at the edge and cloud-based management functions. This segmentation enables thin client simplicity while achieving real-time control response through local processing of time-critical operations.
Solution Approach 2:
Virtual desktop images and device drivers are pre-loaded into edge node caches before needed. This preliminary action reduces startup time and ensures that control operations can be executed immediately without waiting for cloud resource allocation, thereby meeting real-time requirements while maintaining thin client simplicity.
