Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IoT devices use standard network communication protocols, then they can integrate with distributed networks, but their limited communication functionality and security access limitations prevent reliable data transmission
Solution Approach 1:
The patent introduces a hardware adapter as an intermediary device that connects IoT devices to the distributed network. The adapter handles complex communication protocols and security authentication, while the IoT device only needs to provide data through simple interfaces. This mediator resolves the contradiction by enabling reliable network communication without requiring the IoT device to have advanced communication capabilities.
Solution Approach 2:
The system is segmented into three independent components: the IoT device (data source), the hardware adapter (communication handler), and the virtual machine instance (network service interface). This segmentation allows each component to be optimized independently - the IoT device focuses on data collection, the adapter on communication reliability, and the virtual machine on service management, thereby achieving reliable transmission despite limited device functionality.
2Reliability
If IoT devices directly access network services, then communication simplicity is maintained, but security access limitations and restricted interaction with virtual machine instances hinder secure data exchange
Solution Approach 1:
The hardware adapter serves as a security intermediary that implements authentication and authorization mechanisms. It manages security credentials and controls access to virtual machine instances, thereby providing secure data exchange without requiring the IoT device itself to have complex security capabilities. The adapter absorbs the security complexity while maintaining simple device interfaces.
Solution Approach 2:
The system implements self-service security management through the virtual machine instance that automatically authenticates and authorizes connections. The hardware adapter and virtual machine work together to provide automatic security validation, reducing the need for manual security configuration and enhancing security without significantly increasing operational complexity.
3Reliability
If hardware adapters implement comprehensive security protocols, then secure communication is achieved, but processing time and system complexity increase
Solution Approach 1:
Security credentials and authentication mechanisms are pre-configured in the hardware adapter before deployment. This preliminary setup allows for rapid authentication during operation, as the adapter already possesses the necessary security information. This approach achieves comprehensive security protocols while minimizing authentication time during actual data exchange.
Data Source
AI summary
A hardware serial adapter that can be connected to a serial port of a physical computing device and is associated with network credentials that include a unique hardware identifier and other security information. Upon receipt of data (or other initiation command), the hardware serial adapter transmits a registration request with the network credentials to a distributed network service. If the network credentials are valid, the network service provides communication channel configuration information and session credentials to establish a secure communication for the transmission of data from the hardware serial adapter to a virtual machine instance. The distributed network service can control and manage data transmissions and the communication channel.
