Bluetooth Power Control for Smart Wearable Audio Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart wearable devices like smart watches experience high power consumption due to Bluetooth transmissions at maximum power, even when signal quality is not required, leading to reduced battery life, as many Bluetooth devices do not comply with power request rules.
Innovation Solution
Implementing a system that monitors communication scenarios and selects corresponding preset power levels for Bluetooth transmissions, allowing smart wearable devices to control their own power usage based on different scenarios, reducing power consumption and improving battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the smart wearable device transmits Bluetooth signals at maximum power as requested by communication counterpart devices, then the signal quality and communication reliability are improved, but the power consumption increases and battery life is reduced
Solution Approach 1:
The patent implements dynamic power adjustment by monitoring communication scenarios and automatically selecting appropriate power levels. The system transitions from static maximum power transmission to dynamic power control based on real-time communication conditions, resolving the contradiction between maintaining communication reliability and reducing power consumption.
Solution Approach 2:
The patent changes the power transmission parameter from a fixed maximum value to variable values selected from multiple preset power levels. By adjusting the power parameter according to communication scenarios (e.g., audio playback, data synchronization, notifications), the system achieves both reliable communication and reduced power consumption.
2Reliability
If the smart wearable device follows power request rules and transmits at maximum power when requested, then communication quality is maintained, but non-compliant Bluetooth devices cause excessive power consumption
Solution Approach 1:
The patent enables the smart wearable device to independently control its own power transmission without being passively controlled by request signals from counterpart devices. The device monitors communication scenarios itself and autonomously selects appropriate power levels, making it immune to non-compliant power requests while maintaining communication quality.
Solution Approach 2:
The patent implements a feedback mechanism where the device monitors communication scenarios and adjusts power transmission accordingly. This closed-loop control allows the device to respond to actual communication needs rather than blindly following external power requests, achieving both communication quality and power efficiency.
3Ease of operation
If the communication counterpart device controls the power of the smart wearable device, then power management is simplified, but the smart wearable device loses control over its own power consumption
Solution Approach 1:
The patent inverts the traditional power control architecture where the counterpart device requests power from the wearable device. Instead, the wearable device actively monitors communication scenarios and autonomously determines power levels, reversing the control relationship to prioritize the wearable device's power management needs.

AI summary
Disclosed in the present disclosure are a communication method and apparatus, a terminal device, and a storage medium, the method comprising: after a smart wearable device establishes a Bluetooth connection with a communication counterpart device, monitoring the communication scenario between the smart wearable device and the communication counterpart device; on the basis of the communication scenario, selecting a corresponding preset power; and, on the basis of the selected preset power, transmitting scene data between the smart wearable device and the communication counterpart device. The present solution enables the right of power control to be held at the smart wearable device end, and can respond to different predetermined power tables on the basis of different usage scenarios, rather than the transmitting power of the smart wearable device being controlled by the communication counterpart device, thereby reducing the Bluetooth power consumption of the smart wearable device and enhancing battery life, and also avoiding the problem of audio stutter caused by inappropriate power selection.
