Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices experience high power consumption during night-time data communication with cloud servers due to Bluetooth connection maintenance, leading to reduced battery life.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device periodically performs data communication with cloud server to maintain connection, then the connection is maintained, but power consumption increases and battery life is shortened
Solution Approach 1:
The patent implements periodic Bluetooth scanning at configurable intervals (e.g., every 5 minutes, 15 minutes, or 30 minutes) instead of continuous scanning. The device can switch between different scanning modes (active scanning, passive scanning, or no scanning) based on user preferences and battery status, thereby reducing power consumption while maintaining connection reliability.
Solution Approach 2:
The patent introduces a shared device as an intermediary that relays data transmission between the electronic device and the cloud server. The electronic device communicates with the shared device via Bluetooth (low power), which then communicates with the cloud server via Wi-Fi or cellular network (high power), thereby reducing the power consumption of the electronic device while maintaining connection reliability.
2Speed
If Bluetooth scanning is performed frequently to find shared devices, then connection establishment is faster, but power consumption increases
Solution Approach 1:
The patent implements dynamic scanning interval adjustment based on device state. When the electronic device is in idle state (screen off, no active services), scanning intervals are extended (e.g., 30 minutes). When the device is active (screen on, services running), scanning intervals are reduced (e.g., 5 minutes). This dynamic adjustment optimizes the balance between connection establishment speed and power consumption.
Solution Approach 2:
The patent changes the scanning parameter (interval time) based on device state and user preferences. The system supports multiple scanning intervals (5 minutes, 15 minutes, 30 minutes, or custom intervals) that can be configured by users. This parameter change allows the device to adapt scanning frequency to actual needs, reducing unnecessary power consumption while maintaining acceptable connection establishment speed.
3Adaptability or versatility
If the electronic device uses its own data transmission function, then data can be transmitted independently, but power consumption is high
Solution Approach 1:
The shared device serves multiple functions: it acts as a Bluetooth device for local communication, a Wi-Fi/cellular device for cloud communication, and a relay node for data transmission. This multi-functionality allows the electronic device to use the shared device's network connection instead of its own, reducing power consumption while maintaining independent data transmission capability through the shared device.
