Dual Hotspot Network Device Automatic Credential Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart devices require repeated manual network configuration after router access information updates, leading to user inconvenience and potential input errors.
Innovation Solution
A network hotspot device creates two hotspots: an Internet-accessible hotspot and a discovery hotspot. Upon updating access information, it disconnects unconfigured devices from the Internet hotspot and sends the new information through the discovery hotspot, allowing devices to reconnect automatically using the updated credentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual network configuration is required after router access information updates, then network security can be maintained, but user convenience deteriorates and user experience is negatively affected
Solution Approach 1:
The patent implements self-service by enabling the network hotspot device to automatically push updated access information to connected smart devices without requiring user intervention. The system autonomously performs the reconfiguration process, where the hotspot device sends notifications to devices via the discovery hotspot, allowing devices to automatically reconnect with updated credentials, thereby eliminating the need for manual user reconfiguration while maintaining security
Solution Approach 2:
The patent employs feedback mechanisms where the network hotspot device monitors connected devices and sends feedback notifications through the discovery hotspot when access information is updated. This feedback loop allows smart devices to receive real-time updates about changed credentials and automatically adjust their connection parameters, ensuring continuous secure access without user intervention
2Reliability
If smart devices are reconfigured after router access information updates, then network security is maintained, but configuration time increases and productivity decreases
Solution Approach 1:
The patent applies preliminary action by pre-establishing a discovery hotspot that remains active and accessible to smart devices even when the main Internet-accessible hotspot updates its credentials. This preliminary infrastructure allows the system to push updated access information to devices before they need to reconnect, enabling seamless credential updates without interrupting service or requiring devices to undergo full reconfiguration procedures
Solution Approach 2:
The system implements self-service automation where the network hotspot device automatically manages the reconfiguration process. When access information is updated, the hotspot device autonomously identifies connected devices, sends updated credentials through the discovery hotspot, and receives confirmation from devices, eliminating the need for manual configuration operations and significantly reducing configuration time
3Device complexity
If a single hotspot is used for both Internet access and device communication, then device complexity is reduced, but system reliability deteriorates when access information needs to be updated
Solution Approach 1:
The patent applies segmentation by dividing the hotspot functionality into two distinct parts: a discovery hotspot dedicated to device communication and credential distribution, and an Internet-accessible hotspot for actual network connectivity. This segmentation allows the discovery hotspot to maintain stable connections for pushing updates while the Internet hotspot can be reconfigured without affecting device connectivity, thereby improving reliability during access information updates
Solution Approach 2:
The discovery hotspot serves multiple functions: it acts as a communication channel for pushing updated access information to smart devices, provides a stable connection for devices during the update process, and enables the system to maintain connectivity while the Internet hotspot performs credential rotations. This multi-functionality resolves the contradiction by creating a dedicated infrastructure that supports both simplicity and reliability

AI summary
Embodiments of the present disclosure provide methods and devices for enabling access of an unconfigured device to a network hotspot device. The network hotspot device creates a first hotspot and a second hotspot. The method can include: in response to first access information of the first hotspot having been updated, disabling, by the network hotspot device, a connection between the first hotspot of the network hotspot device and the unconfigured device that has accessed the network hotspot device through the first hotspot; and in response to the unconfigured device accessing the second hotspot, sending, by the network hotspot device, the updated first access information to the unconfigured device through the second hotspot, wherein the unconfigured device is configured to access the first hotspot using the updated first access information.
