Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If time division multiplexing is used to allocate channels to multiple Bluetooth devices, then the electronic device can maintain connections with multiple devices, but the transmission latency increases and data throughput speed decreases when large amounts of data need to be transmitted
Solution Approach 1:
The patent dynamically adjusts the connection interval of the first Bluetooth device based on the data transmission requirements of the second Bluetooth device. When the second device requires large bandwidth for data transmission, the system increases the connection interval of the first device, allowing more channel time to be allocated to the second device. This dynamic adjustment resolves the contradiction by making the connection interval flexible rather than fixed, enabling the system to adapt to varying data transmission demands while maintaining multiple connections.
Solution Approach 2:
The patent changes the connection interval parameter of the first Bluetooth device from a fixed value to a variable that can be adjusted based on real-time transmission needs. By modifying this key parameter, the system can allocate more time resources to devices with higher data transmission requirements, thereby reducing transmission latency and increasing throughput speed without completely breaking the connection to the first device.
2Adaptability or versatility
If time division multiplexing is used to allocate channels to multiple Bluetooth devices, then the electronic device can maintain connections with multiple devices, but the data throughput speed decreases when large amounts of data need to be transmitted
Solution Approach 1:
The system dynamically adjusts the connection interval of the first Bluetooth device based on real-time assessment of data transmission requirements. When the second device has large amounts of data to transmit, the system increases the first device's connection interval, thereby freeing up more channel time for the second device. This dynamic reconfiguration enables the system to optimize data throughput speed adaptively while maintaining connectivity with multiple devices.
Solution Approach 2:
By changing the connection interval parameter of the first Bluetooth device from a static value to a dynamically adjustable parameter, the system can reallocate time resources to prioritize high-bandwidth devices. This parameter change allows the system to increase data throughput speed for devices with large data transmission needs without completely disconnecting other devices, thus resolving the productivity limitation.
3Adaptability or versatility
If channel time is allocated to another Bluetooth device, then multiple device connections are maintained, but real-time performance of audio data transmission is reduced
Solution Approach 1:
The patent implements dynamic adjustment of connection intervals based on real-time transmission requirements. When audio data transmission to the second Bluetooth device is detected, the system increases the connection interval of the first device, allocating more time resources to the audio transmission. This dynamic response ensures that real-time performance requirements are met while maintaining multi-device connectivity.
Solution Approach 2:
The system changes the connection interval parameter of the first Bluetooth device in response to real-time audio transmission needs. By adjusting this parameter dynamically, the system can prioritize time-sensitive audio data transmission, ensuring that real-time performance requirements are satisfied while still maintaining connections with multiple devices.

AI summary
A Bluetooth connection method and a related apparatus are disclosed, and relate to the field of short-range wireless communications technologies. A first electronic device establishes a BLE connection to a second electronic device, and exchanges data with the second electronic device based on a first connection interval. The first electronic device further establishes a BR/EDR connection to a third electronic device. When device class information of the second electronic device is the same as device class information prestored in a memory, the first electronic device exchanges data with the second electronic device based on a second connection interval. The second connection interval is greater than the first connection interval. In this way, a throughput speed of exchanging data by the third electronic device can be increased.
