Engineering Contradiction Analysis
1Speed
If traditional BLE connection parameters are used, then connection stability is maintained, but transmission rate remains low and cannot meet high-speed data transmission requirements
Solution Approach 1:
The patent implements dynamic adjustment of connection interval parameters based on real-time transmission rate monitoring. The system transitions from static BLE parameters to dynamic parameter adjustment, where the connection interval is continuously optimized based on actual transmission performance, enabling the system to adaptively achieve high-speed transmission when conditions permit while maintaining stability when needed
Solution Approach 2:
The patent changes key BLE transmission parameters including connection interval, transmission power, and packet size to optimize transmission rate. By modifying these parameters dynamically based on monitoring results, the system overcomes the limitation of fixed BLE parameters and achieves variable transmission speeds to meet different application requirements
2Speed
If connection interval is reduced to increase transmission frequency, then transmission rate improves, but energy consumption increases and connection stability may deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where transmission rate is continuously monitored and used to adjust connection interval parameters. This closed-loop control ensures that the connection interval is only reduced when transmission rate benefits are achieved, preventing unnecessary energy consumption from overly frequent connections while maintaining optimal transmission performance
Solution Approach 2:
The system dynamically adjusts connection interval based on real-time transmission needs rather than using a fixed interval. This allows the system to increase connection frequency temporarily when high transmission rates are needed while returning to lower frequency (lower energy consumption) when high-speed transmission is not required, achieving energy-efficient high-speed transmission
3Speed
If existing BLE parameter settings are used, then device compatibility is maintained, but transmission rate cannot be optimized for high-speed scenarios
Solution Approach 1:
The patent transforms static BLE parameters into dynamic, adjustable parameters that can be optimized for different transmission scenarios. The system maintains compatibility with standard BLE devices while adding the capability to dynamically adjust parameters for high-speed transmission when needed, achieving both compatibility and optimized performance
Solution Approach 2:
The patent creates a multi-functional parameter management system that can operate in both standard BLE mode (for compatibility) and optimized high-speed mode (for performance). The same parameter management mechanism handles both conventional and enhanced transmission requirements, making the system universally applicable across different scenarios
