Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If unlicensed networks are used for IoT device communication, then ease of deployment and device integration is improved, but network security and vulnerability to hacking deteriorates
Solution Approach 1:
The patent introduces a centralized communication system as an intermediary between IoT devices and external networks. This system implements a secure hub that mediates all communications, providing authentication, encryption, and security management. The hub acts as a trusted intermediary that enables unlicensed network deployment while maintaining security through centralized control and monitoring of all device interactions.
2Adaptability or versatility
If multiple IoT devices from different companies are integrated, then device functionality and smart home capability is improved, but security management and protocol integration complexity deteriorates
Solution Approach 1:
The patent implements a universal communication system that can integrate multiple types of IoT devices from different manufacturers through a single centralized hub. The system provides universal authentication mechanisms, standardized encryption protocols, and unified security management that work across diverse device types including sensors, cameras, and control devices, eliminating the need for device-specific security configurations.
Solution Approach 2:
The patent consolidates multiple security functions and device management capabilities into a single centralized communication system. By merging authentication, encryption, device registration, and security policy enforcement into one hub, the system reduces the complexity of managing security across multiple devices while maintaining comprehensive control over the entire IoT ecosystem.
3Reliability
If centralized communication system with Blockchain is implemented, then network security and data protection is improved, but system complexity and computational requirements deteriorates
Solution Approach 1:
The patent uses the centralized communication system as an intermediary that implements Blockchain technology for secure data storage and device authentication. The hub manages Blockchain operations, cryptographic key generation, and distributed ledger maintenance, shielding individual IoT devices from the computational complexity of Blockchain while still benefiting from its security properties through simplified integration interfaces.
Data Source
AI summary
Secure control of network appliances uses a 5G compatible central hub connected to a plurality of network appliances or multiple hubs in a local area network (LAN) or wireless LAN. A master hub controls communication with the appliances and also includes a 5G cellular link for communication with a cellular network. Only the master hub can communicate with the Internet via the cellular link. User equipment (UE) contains an application program that works in conjunction with the central hub to control the appliances. Upon receipt of an authenticated command, the central hub propagates commands to the intended network appliance. The central hub includes a voice command module to permit a user to control operation of the network appliances using voice commands.
