Robot Cleaner NFC Pairing for Secure Remote Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robot cleaners face challenges in easy user control and security, particularly when using external terminals for remote operation, as they often require complex AP information input and may expose indoor image information to unauthorized access.
Innovation Solution
The integration of a NFC module within the robot cleaner to provide AP information directly to external terminals via NFC communication, enabling secure and easy Wi-Fi connection for remote control and monitoring, while maintaining security by restricting the NFC module to read-only operations and excluding direct communication with the main controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera module is mounted in the robot cleaner for security monitoring, then the security monitoring capability is improved, but the risk of image information being exposed to hackers increases
Solution Approach 1:
The patent introduces a separate communication module as an intermediary between the camera module and the external network. This communication module acts as a mediator that controls and filters data transmission, preventing direct access to the camera module and thus protecting image information from being exposed to hackers while maintaining security monitoring capability.
2Ease of operation
If remote control functionality is added to the robot cleaner, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal communication module that handles multiple functions including remote control, data transmission, and camera module communication. By using a single multi-functional communication module instead of separate dedicated modules for each function, the patent reduces overall system complexity while providing comprehensive remote control capability.
