Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Bluetooth earphone data transmission methods are limited to single-direction communication, failing to meet user requirements for efficient audio data transmission between multiple earphones and a mobile terminal.
Innovation Solution
A data transmitting method and system where multiple Bluetooth earphones form a connection loop with a mobile terminal, allowing each earphone to have two transmission paths to the terminal, enabling the selection of the shorter path for faster audio data transmission by determining the target device as either another earphone or the mobile terminal based on the number of earphones in each path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If Bluetooth earphones use single-direction data transmission, then the system is simple to implement, but the data transmission efficiency cannot meet user requirements
Solution Approach 1:
The patent implements dynamic path selection where each Bluetooth earphone can choose between two transmission directions (clockwise or counter-clockwise) based on real-time conditions. The system dynamically determines the optimal transmission path by comparing the number of earphones in each direction, allowing the transmission topology to adapt and change based on current system state rather than being fixed in one direction.
Solution Approach 2:
The patent divides the transmission network into multiple independent paths by forming a loop structure where each earphone has two separate transmission routes to reach the mobile terminal. This segmentation of transmission paths allows parallel transmission options and enables selection of the shorter path, improving overall data transmission efficiency without requiring a complete redesign of the Bluetooth connection architecture.
2Productivity
If Bluetooth earphones form a connection loop with multiple transmission paths, then data transmission efficiency is improved, but the device complexity increases
Solution Approach 1:
The system employs dynamic path selection algorithms that automatically determine the optimal transmission route by comparing path lengths. Each earphone can switch between clockwise and counter-clockwise transmission modes based on real-time calculations of the number of devices in each path, making the connection structure adaptable and efficient without requiring manual configuration or complex hardware changes.
Solution Approach 2:
The Bluetooth earphones autonomously determine their own transmission paths by calculating the number of devices in each direction independently. Each earphone performs self-assessment of the connection topology and automatically selects the shorter path without requiring centralized control or complex coordination protocols, reducing overall system complexity while maintaining high transmission efficiency.
3Loss of time
If the system selects the shorter transmission path, then transmission time is reduced, but the difficulty of determining the target device increases
Solution Approach 1:
The system performs preliminary path analysis by counting the number of Bluetooth earphones in each transmission direction before actual data transmission begins. This pre-calculation of path lengths allows the system to identify the shorter path in advance, so when data needs to be transmitted, the target device and path are already determined, reducing actual transmission time without requiring complex real-time decision-making during data flow.
Solution Approach 2:
The system uses feedback mechanisms where each earphone reports its position and connection status to neighboring devices, enabling collective determination of the optimal transmission path. Through iterative communication and path validation, the system converges on the shorter path selection, reducing the complexity of target device identification while ensuring optimal transmission time.
