Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth 4.0 specification is used, then power-saving and encryption features are improved, but communication compatibility with mobile terminals deteriorates
Solution Approach 1:
The patent introduces an intermediary translation layer that converts between Bluetooth 4.0 protocols and mobile terminal protocols. The communication module acts as a mediator, translating data packets between the two different protocol systems, thereby maintaining encryption reliability while achieving compatibility with mobile terminals that use different Bluetooth versions
Solution Approach 2:
The patent dynamically adjusts communication parameters such as data transmission rate, packet structure, and protocol version based on the detected mobile terminal type. By changing these parameters adaptively, the system maintains optimal encryption performance while ensuring compatibility across different device types
2Use of energy by moving object
If Bluetooth 4.0 specification is used, then power-saving feature is improved, but communication stability with mobile terminals deteriorates
Solution Approach 1:
The patent implements dynamic power management that adjusts the Bluetooth device's operational state based on communication requirements. The system can switch between low-power sleep mode and active communication mode, maintaining power-saving benefits while ensuring stable communication when data transmission is required
Solution Approach 2:
The patent incorporates feedback mechanisms that monitor communication quality and power consumption in real-time. Based on this feedback, the system automatically adjusts transmission power, data rate, and sleep intervals to maintain communication stability while optimizing power savings
3Ease of manufacture
If Bluetooth 4.0 specification is used, then low cost is improved, but communication performance with mobile terminals deteriorates
Solution Approach 1:
The patent designs a universal communication module that can operate with multiple Bluetooth versions and protocol types. This multi-functional approach allows a single low-cost hardware design to achieve broad compatibility while maintaining good communication performance across different device types through software-based protocol adaptation
