Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for integrating new computing devices into modern operation and control systems or IoT networks are either manual and error-prone or limited by pre-configured container runtime environments, which restrict device-specific capabilities and protocol usage.
Innovation Solution
A distributed computing infrastructure with a device management service that automates the configuration and integration of new computing devices by listening for broadcasting messages, connecting via SSH, downloading device descriptions, creating security certificates, and deploying a container runtime environment with required connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual engineering approach is used to configure new devices, then device integration can be customized, but the process is tedious and error-prone leading to inefficiency and high costs
Solution Approach 1:
The device is pre-configured with a container runtime environment and default SSH credentials before deployment. This preliminary setup enables automatic connection and configuration by the device management service without requiring manual engineering intervention, thus resolving the contradiction between customization capability and integration efficiency
Solution Approach 2:
The joining computing device automatically broadcasts its presence and receives configuration from the device management service without human intervention. The device self-configures by receiving container runtime environment, connectors, and security certificates automatically, eliminating manual configuration steps while maintaining customization through device-specific descriptors
2Ease of operation
If device pre-configuration with container runtime environment is used, then devices are ready for software deployment, but integration is limited to homogeneous scenarios or standard runtime environments
Solution Approach 1:
The configuration is segmented into device-specific components: each device has its own descriptor file containing hardware capabilities, supported connectors, and protocol information. This segmentation allows the universal device management service to adapt to diverse device types while maintaining ease of operation through standardized container runtime deployment
Solution Approach 2:
The system applies local quality by downloading and applying device-specific connectors and configuration parameters based on the individual device's capabilities described in its descriptor. This enables each device to receive customized configuration tailored to its specific hardware and protocol requirements while using the same overall automation approach
3Device complexity
If standardized container runtime environment is used, then device integration is simplified, but device-specific compute capabilities such as FPGA cannot be utilized
Solution Approach 1:
Device-specific connectors act as intermediaries between the standardized container runtime environment and device-specific capabilities such as FPGAs, I/O interfaces, and communication protocols. These connectors enable the universal container runtime to access and utilize specialized hardware resources without increasing integration complexity for end users
4Reliability
If operators manually connect to new devices for initial network configuration, then secure communication can be established, but the process requires significant time and human intervention
Solution Approach 1:
Default SSH credentials are pre-configured on the joining device before it joins the network. This preliminary action enables the device management service to automatically establish secure SSH connections without requiring operator intervention for initial authentication, significantly reducing configuration time while maintaining security through subsequent certificate-based authentication
