Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If Bluetooth module is used for data transmission, then point-to-point data sharing is achieved, but transmission distance and coverage area are limited
Solution Approach 1:
The patent changes the operating parameters of the wireless communication module by switching between bypass mode and operation mode. In operation mode, the module achieves extended transmission distance (beyond preset distance) with enhanced signal transmission-reception functions, while in bypass mode it provides reliable short-distance communication. This parameter switching resolves the contradiction between transmission distance and reliability.
2Area of stationary object
If transmission power is increased to extend coverage area, then data transmission distance is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic transmission power adjustment based on predetermined information including system time, flow of people in predetermined area, and location information. The transmission power is adaptively changed according to environmental conditions, achieving extended coverage area when needed while consuming minimal power during normal operation. This dynamic adjustment resolves the contradiction between coverage area and power consumption.
Solution Approach 2:
The patent changes the transmission power parameter dynamically based on operational conditions. By switching between different power levels according to system time, location, and environmental factors, the system achieves extended coverage when required while maintaining low power consumption during normal operation, resolving the contradiction between coverage area and power usage.
3Use of energy by moving object
If LPWAN module operates in bypass mode, then short-distance communication is achieved, but transmission distance is limited
Solution Approach 1:
The patent implements dynamic mode switching between bypass mode and operation mode based on communication requirements. When extended transmission distance is needed, the system switches to operation mode with enhanced signal transmission-reception functions. When short-distance communication suffices, bypass mode provides power-efficient operation. This dynamic switching resolves the contradiction between power efficiency and transmission distance.
