TWS Headset Program Upgrade via Direct Terminal Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing program upgrade process for true wireless stereo (TWS) headphones is prone to instability and prolongs the upgrade time due to unstable connections between the master and slave headphones, and it occupies hardware resources of the master headphone.
Innovation Solution
A method and system for upgrading TWS headphones where each headphone establishes a separate wireless communication connection with a terminal, receiving upgrade files independently, eliminating the need for a communication connection between the master and slave headphones for data transfer, thus avoiding upgrade failures and reducing resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the master headphone is used as a relay station to upgrade the slave headphone, then the upgrade process can be completed through existing headphone hardware, but the connection stability deteriorates and upgrade time increases
Solution Approach 1:
The patent divides the upgrade process into two independent segments: first upgrading the master headphone directly through the terminal, then upgrading the slave headphone directly through the terminal. This segmentation eliminates the need for the master headphone to act as a relay, thereby avoiding connection instability and reducing overall upgrade time.
Solution Approach 2:
The terminal device serves as the intermediary for both headphones during the upgrade process. Instead of using the master headphone as an intermediary for the slave headphone upgrade, the terminal directly communicates with both devices, eliminating the unstable master-slave connection during data transfer.
2Ease of operation
If the master headphone acts as a relay station for slave headphone upgrade, then hardware resources of the master headphone are utilized, but hardware resources are occupied and connection stability decreases
Solution Approach 1:
The patent segments the upgrade operations so that the master and slave headphones are upgraded independently through separate direct connections to the terminal. This eliminates the need for the master headphone to serve as a relay station, thereby maintaining connection stability while preserving operational simplicity.
3Reliability
If separate wireless connections are established for each headphone, then upgrade reliability improves and resource consumption reduces, but communication protocol complexity increases
Solution Approach 1:
The terminal device performs multiple functions: it serves as the upgrade source for both the master and slave headphones, manages both wireless connections, and coordinates the sequential upgrade process. This universal approach simplifies the overall system by consolidating control in the terminal rather than requiring complex inter-headphone communication protocols.

AI summary
Provided are a program upgrade method, a TWS headphone, a method and system for upgrading a program of a TWS headphone. The program upgrade method, applied to a TWS headphone including a first wireless headphone and a second wireless headphone arranged in pairs, includes, establishing a wireless communication connection between the first wireless headphone and terminal, and receiving, by the first wireless headphone, a first upgrade file sent by the terminal for upgrade; and establishing a wireless communication connection between the second wireless headphone and the terminal, and receiving, by the second wireless headphone, a second upgrade file sent by the terminal for upgrade after the first wireless headphone completes upgrade.
