Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual WiFi key input configuration is used, then security data can be provided to IoT devices, but the configuration process becomes complex and burdensome for users
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the WiFi router and IoT device. The mobile device captures WiFi security data from the router and automatically transmits it to the IoT device, eliminating the need for users to manually input complex WiFi credentials. This intermediary approach simplifies the configuration process while maintaining secure data transmission.
Solution Approach 2:
The system enables self-service configuration where the IoT device automatically receives and configures WiFi security data without requiring user intervention. The mobile device and IoT device work together to automatically establish the WiFi connection, allowing users to simply plug and play without technical knowledge.
2Ease of operation
If simplified configuration process is implemented, then ease of operation improves, but secure sharing and management of WiFi security data becomes challenging
Solution Approach 1:
The patent replaces manual mechanical input methods with wireless automated transmission. WiFi security data is transmitted automatically through wireless communication channels from the mobile device to the IoT device, eliminating the need for manual key entry while maintaining security through automated authenticated transmission.
Solution Approach 2:
The mobile device acts as a secure intermediary that captures WiFi credentials from the router and relays them to the IoT device. This intermediary approach ensures secure handling of security data throughout the transmission process, maintaining reliability while simplifying user interaction.
3Productivity
If direct device pairing is used, then configuration can be completed, but technical complexity increases for users with limited skills
Solution Approach 1:
The mobile device serves as an intermediary that handles the complex pairing and authentication processes between the WiFi router and IoT device. Users only need to interact with the simple mobile device interface, while the complex device-to-device pairing is automatically managed in the background, reducing perceived complexity.
Solution Approach 2:
The system performs preliminary actions by having the mobile device capture and store WiFi security data before the IoT device needs to connect. This pre-preparation of security credentials allows for rapid configuration of the IoT device without requiring users to understand complex pairing procedures at the moment of setup.
Data Source
AI summary
A method and system for connecting an Internet of Things (IoT) hub to a wireless network. One embodiment of the method includes establishing a secure communication channel between an IoT hub and an IoT service through a client device using a first secret; generating a second secret on the client device and transmitting it to the IoT hub; encrypting a wireless key using the second secret to generate a first-encrypted key and transmitting it to the IoT service; encrypting the first-encrypted key using the first secret to generate a twice-encrypted key and transmitting it to the IoT hub over the secure communication channel; decrypting the twice-encrypted key at the IoT hub using the first secret to generate the first-encrypted key and decrypting it using the second secret to generate the wireless key usable to establish a secure wireless connection between the IoT hub and the local wireless network.
