Solution Overview
Problem
In Bluetooth communication connections, electronic devices often perform unnecessary power-consuming scan or advertising operations when attempting to connect with other devices that are not on the network, leading to inefficient energy usage.
Innovation Solution
An electronic device provides information indicating the existence of a second audio electronic device on the network, allowing the first device to determine if a scan or advertising operation is necessary, thereby preventing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electronic device continuously performs scan or advertising operations to establish Bluetooth connection, then connection establishment capability is improved, but power consumption increases
Solution Approach 1:
The patent applies preliminary action by having the first audio electronic device obtain information about the second audio electronic device's existence on the network before performing scan or advertising operations. This allows the device to prepare in advance and avoid unnecessary continuous scanning, thereby reducing power consumption while maintaining connection establishment capability.
Solution Approach 2:
The patent implements feedback by using existence information of the second audio electronic device to control whether to perform scan or advertising operations. The system receives feedback about device presence and adjusts its scanning behavior accordingly, stopping unnecessary operations when the target device is confirmed to be absent, thus optimizing power consumption.
2Reliability
If a device performs continuous scan operation to detect advertising signal, then detection reliability is improved, but energy efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by obtaining existence information about the second audio electronic device before initiating continuous scan operations. This preliminary check allows the system to avoid unnecessary continuous scanning when the target device is known to be absent, thereby maintaining detection reliability when needed while improving energy efficiency by avoiding wasted scanning operations.
Solution Approach 2:
The patent implements feedback by using the obtained existence information to control the scanning behavior. When feedback indicates the second audio electronic device does not exist on the network, the system stops continuous scanning, thus preventing energy loss while maintaining the ability to detect devices when they are present.
