Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices powered by batteries experience rapid depletion due to high power consumption levels, particularly in IoT devices with varying operation modes and network communication requirements.
Innovation Solution
The electronic devices select their power consumption modes based on operation modes and use profiles managed by a server system, which includes power save modes like on-off, PSM, eDRX, and combined modes, optimizing power usage through profile selection and parameter settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the electronic device operates at a high power consumption level, then the performance and network communication capability are improved, but the battery depletes quickly
Solution Approach 1:
The patent implements dynamic power consumption mode selection where the electronic device transitions between different operation modes (active, idle, sleep, deep sleep) based on real-time conditions such as network activity, data transmission requirements, and operational state. This dynamic adaptation allows the device to optimize power consumption while maintaining necessary performance levels, directly resolving the contradiction between high power consumption for improved performance and extended battery life.
2Productivity
If the electronic device frequently communicates with the wireless network, then the data communication capability is improved, but the power consumption increases
Solution Approach 1:
The patent employs periodic communication cycles with defined active and inactive periods. During active periods, the device communicates with the wireless network to maintain data communication capability. During inactive periods, the device enters low-power states with reduced or suspended communication activity. This periodic pattern allows the device to balance data communication requirements with power consumption constraints, enabling productive network interaction while conserving energy during periods when communication is less critical.
