IoT Device Direct Repeater Communication Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IoT systems require a gateway to minimize power consumption in IoT devices, which is inconvenient and increases power consumption during wireless communication with repeaters.
Innovation Solution
An IoT device that can directly communicate with a repeater without a gateway, operating in repeater mode when conditions are met, transitioning to terminal mode upon receiving specific signals, and entering sleep mode when conditions are not met, thereby minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a gateway is used to mediate communication between IoT devices and repeaters, then power consumption of IoT devices is minimized, but device complexity and system inconvenience increase
Solution Approach 1:
The patent extracts and removes the gateway component from the system architecture. IoT devices directly communicate with repeaters using WiFi protocol, eliminating the need for gateway mediation. This extraction resolves the contradiction by removing the source of complexity while accepting direct communication power consumption as the trade-off.
Solution Approach 2:
The repeater is designed to perform multiple functions: it acts as both a WiFi access point for direct IoT device connection and a Zigbee gateway for legacy device support. This multi-functionality allows the system to eliminate the dedicated gateway component while maintaining compatibility with both communication protocols.
2Device complexity
If IoT devices communicate directly with repeaters using WiFi protocol, then system complexity is reduced, but power consumption increases
Solution Approach 1:
The patent implements periodic action through scheduled communication intervals and sleep-wake cycles. IoT devices transmit status information at predetermined intervals and enter sleep mode between transmissions, reducing overall power consumption while maintaining direct WiFi communication with repeaters.
Solution Approach 2:
The patent changes communication parameters including transmission power levels, data packet sizes, and communication frequency. By optimizing these parameters, the system reduces power consumption during direct WiFi communication while maintaining adequate connectivity and data transmission efficiency.
3Use of energy by moving object
If gateway performs authentication and connection processes in advance, then power consumption during data transmission is minimized, but loss of time occurs during setup
Solution Approach 1:
The patent applies preliminary action by having the repeater pre-authenticate and establish connection parameters with IoT devices during initial setup. The repeater stores authentication credentials and connection configurations, enabling IoT devices to skip lengthy authentication processes during subsequent communications, thus reducing both time and power consumption.
4Speed
If IoT devices frequently wake up to check for mode change signals, then responsiveness is improved, but power consumption increases
Solution Approach 1:
The patent implements feedback mechanisms where the repeater actively notifies IoT devices of mode changes through predetermined signal patterns. Instead of IoT devices continuously polling for changes, the system uses event-driven notification where the repeater sends wake-up signals only when mode changes occur, balancing responsiveness with power conservation.
