Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robot cleaners face challenges in user control and security, particularly in expanding remote control functionality and monitoring cleaning history, with difficulties in inputting additional functions through remote controls and concerns about camera module security when hacked.
Innovation Solution
A robot cleaner system equipped with a Wi-Fi module providing Access Point (AP) information via NFC communication, allowing secure Wi-Fi communication with an external terminal for control and monitoring, and a camera module for generating location information, enhancing user satisfaction by visualizing cleaning history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a robot cleaner uses a remote control device for basic operations, then ease of operation is improved, but adaptability for additional functions deteriorates
Solution Approach 1:
The patent implements a Wi-Fi module that enables the robot cleaner to connect to external terminals (smartphones, tablets, computers) through wireless networks. This allows the device to perform multiple functions including remote control, cleaning history monitoring, and system configuration beyond basic remote control operations. The universal interface accommodates various external devices and operations, resolving the contradiction between ease of operation and adaptability.
2Adaptability or versatility
If a robot cleaner includes a camera module for monitoring, then functionality is improved, but security vulnerability deteriorates
Solution Approach 1:
The patent implements an authentication mechanism where the Wi-Fi module verifies authentication information from external terminals before allowing communication. This preliminary security check prevents unauthorized devices from accessing the camera module or other sensitive functions, counteracting potential security threats before they can materialize. The system proactively defends against hacking attempts while maintaining the enhanced functionality provided by the camera module.
3Adaptability or versatility
If a robot cleaner enables Wi-Fi communication for remote control, then adaptability is improved, but device complexity deteriorates
Solution Approach 1:
The patent integrates the Wi-Fi module directly into the robot cleaner's existing structure, combining wireless communication functionality with the cleaning device. By merging the Wi-Fi module, camera module, and authentication system into a single integrated unit, the patent reduces overall system complexity compared to using separate auxiliary devices. The combined design allows multiple functions (remote control, monitoring, authentication) to be achieved through one unified system rather than multiple independent components.
