Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If Bluetooth Classic (BR/EDR) is used for communication, then data transmission capability is improved, but power consumption increases
Solution Approach 1:
The system dynamically switches between Bluetooth Low Energy (BLE) and Bluetooth Classic (BR/EDR) communication modes based on real-time requirements. BLE is used for low-power operations and initial connection establishment, while BR/EDR is activated only when high data transmission capability is needed, thus optimizing the balance between power consumption and transmission performance
Solution Approach 2:
The communication process is segmented into different phases: initial device discovery and connection using BLE, and subsequent high-speed data transfer using BR/EDR. This segmentation allows the system to use the most energy-efficient communication mode for each specific task, avoiding unnecessary power consumption
2Ease of operation
If manual connection procedure is used for Bluetooth devices, then connection control flexibility is improved, but ease of operation deteriorates
Solution Approach 1:
The system implements self-service automatic connection functionality where devices automatically discover each other via BLE advertising messages and initiate connection procedures without requiring manual user intervention. The devices autonomously complete pairing and establish communication, making the operation extremely simple while maintaining high automation
Solution Approach 2:
The system uses BLE advertising messages to provide feedback about device availability, supported communication modes, and service information. This feedback mechanism enables automatic connection decisions to be made based on real-time device states, improving both ease of operation and automation
3Device complexity
If substitute communication means activation is performed without pre-information, then device complexity is reduced, but loss of information increases
Solution Approach 1:
The system performs preliminary actions by including service information and alternative communication means details in BLE advertising messages before actual connection is established. This allows the receiving device to pre-process and prepare for activation, reducing complexity during the actual activation phase while ensuring no service information is lost
Solution Approach 2:
BLE advertising messages serve as an intermediary that carries service information and alternative communication means details from one device to another before the actual connection is established. This intermediary mechanism allows information to be exchanged and prepared in advance, simplifying the subsequent activation process while preserving all necessary service information
