Bluetooth Reconnection Circuit Reducing Power Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth communication disconnection between electronic devices leads to increased power consumption when attempting reconnection, as existing methods require frequent activation of components, particularly in devices with more components, limiting their usage for Bluetooth functions.
Innovation Solution
An electronic device with a Bluetooth communication circuit, processor, and memory that stores instructions to periodically attempt reconnection without repeated invocation of application programming interfaces (APIs), allowing the Bluetooth chip to handle reconnection requests and reduce processor operation, thereby minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device periodically and repeatedly transmits connection requests to reconnect Bluetooth communication, then Bluetooth communication can be reconnected, but power consumption increases due to frequent activation of the application processor
Solution Approach 1:
The patent segments the reconnection functionality by separating the transmission of connection requests from the processing logic. The Bluetooth communication circuit (independent module) handles periodic connection request transmission, while the application processor is invoked only when necessary (upon disconnection detection or reconnection completion), rather than being repeatedly activated for each transmission cycle.
Solution Approach 2:
The Bluetooth communication circuit performs self-service by autonomously transmitting connection requests to external devices without requiring repeated intervention from the application processor. The circuit independently manages the reconnection process, only involving the processor when initial disconnection is detected or when reconnection is successfully established.
2Reliability
If the electronic device with more components performs reconnection operations, then reconnection can be achieved, but power consumption is higher compared to accessory type external devices
Solution Approach 1:
The patent extracts the periodic connection request transmission function from the application processor and assigns it to the Bluetooth communication circuit. This separation removes the burden of continuous transmission operations from the complex processor, allowing it to remain inactive during routine transmission cycles and activate only when necessary.
Solution Approach 2:
Instead of having the application processor continuously manage connection attempts (the conventional approach), the patent inverts the control structure: the Bluetooth communication circuit autonomously initiates and manages periodic connection requests, reversing the traditional hierarchy where the processor controls all communication operations.
