Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gateway maintains continuous communication connection with terminal devices for real-time monitoring, then monitoring reliability is improved, but power consumption increases for battery-powered devices
Solution Approach 1:
The patent applies dynamics by making the communication connection state adjustable rather than fixed. The gateway can dynamically switch between maintaining continuous connections and disconnecting based on device type and monitoring requirements. This allows the system to adapt the connection state to balance reliability and power consumption needs.
Solution Approach 2:
The patent changes the parameter of communication connection state (connected vs. disconnected) based on device characteristics. By identifying different device types and their power supply modes, the system adjusts the connection parameter accordingly - maintaining connections for AC-powered devices while disconnecting from battery-powered devices when monitoring is complete.
2Productivity
If the gateway maintains continuous communication connection with all terminal devices, then data communication efficiency is improved, but device complexity increases to manage diverse device types
Solution Approach 1:
The patent segments terminal devices into different categories based on their power supply modes and monitoring requirements. By classifying devices as AC-powered or battery-powered, and further dividing them into types requiring continuous monitoring versus periodic reporting, the system can apply different communication strategies to each segment, simplifying overall system management.
Solution Approach 2:
The gateway is designed with multi-functionality to handle diverse device types through a unified interface. It can identify device types, determine appropriate monitoring modes, and manage multiple connection states simultaneously, making the system adaptable to various terminal devices without requiring separate management mechanisms for each device type.
3Use of energy by moving object
If the gateway disconnects communication connection to save power, then power consumption is reduced, but monitoring responsiveness deteriorates
Solution Approach 1:
The patent implements periodic action by having battery-powered devices report data at scheduled intervals rather than maintaining continuous real-time communication. The gateway disconnects the connection after data transmission, and devices re-establish connection periodically to upload new data, achieving power savings while maintaining acceptable monitoring coverage.
Data Source
AI summary
A method for monitoring Internet of Things (IoT) devices includes activating a communication connection with a terminal device in response to a monitoring request for the terminal device, conducting communications of monitoring data corresponding to the monitoring request via the communication connection, and controlling a state of the communication connection according to an operating mode of the terminal device.
