Wireless Earpiece Power Management Through Threshold-Based Master Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is an imbalance in battery usage between first and second earpieces of wireless earphones, leading to potential degradation of audio quality due to role changes without proper conditions.
Innovation Solution
An electronic device for audio manages power by generating a communication link and changing the master role from one earpiece to another when the battery difference exceeds a threshold, ensuring balanced battery usage and continuous audio output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the master role is changed without conditions between earpieces, then the battery usage imbalance can be addressed, but the audio quality degrades due to discontinuous audio data
Solution Approach 1:
The system monitors battery capacity parameters of both earpieces and changes the master role based on threshold comparisons. When the battery capacity difference exceeds the threshold, the system automatically switches which earpiece serves as master, thereby balancing energy consumption while maintaining audio continuity through controlled parameter-based role transitions
Solution Approach 2:
The system continuously monitors battery capacity levels of both earpieces and uses this feedback to determine when to switch the master role. This closed-loop feedback mechanism ensures that role changes occur only when necessary (when imbalance exceeds threshold), preventing unnecessary audio interruptions while addressing battery usage imbalance
2Loss of energy
If the master role is changed frequently to balance battery usage, then energy distribution improves, but system stability deteriorates
Solution Approach 1:
The system introduces a threshold parameter that must be exceeded before triggering a master role change. This parameter-based control prevents frequent or minor role switches, ensuring system stability by only changing roles when the battery imbalance reaches a significant level, thus balancing energy distribution without excessive role switching
3Stability of the object's composition
If the master role is held fixed in one earpiece, then system stability is maintained, but battery usage becomes unbalanced
Solution Approach 1:
The system transitions from a static master role assignment to a dynamic one where the master role can switch between earpieces based on real-time battery capacity monitoring. This dynamic adaptation allows the system to maintain stability during normal operation while automatically rebalancing energy consumption when imbalance exceeds the threshold
Solution Approach 2:
The system uses battery capacity as a dynamic parameter to determine master role assignment. When the battery capacity difference between earpieces exceeds the threshold, the parameter change triggers a role swap, enabling the system to adapt to changing energy levels and maintain balanced power consumption over time

AI summary
A first earpiece device and a power management method for the first earpiece device are provided. A first communication link with a second earpiece device is generated via a communication circuit and first audio data obtained from an external electronic device via the communication circuit is stored in a buffer. A master role from the first earpiece device is changed to the second earpiece device based on: identifying a buffer level corresponding to the first audio data to be output via the first earpiece device, identifying a remaining battery capacity of the first earpiece device being smaller than a remaining battery capacity of the second earpiece device, and a difference between the remaining battery capacity of the first earpiece device and the remaining battery capacity of the second earpiece device being greater than or equal to a threshold value.
