Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active electronic seal is used, then automatic warning signal transmission is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines active and passive electronic seal functionalities into a single composite seal system. The seal includes both a passive RFID chip for basic identification and an active component with battery-powered warning signal transmission capability, allowing the system to operate in multiple modes depending on the reading equipment available.
Solution Approach 2:
The composite electronic seal is designed to be compatible with both active and passive RFID reading equipment used by different countries' customs authorities. The seal can function as a passive seal for data reading and as an active seal for automatic warning signal transmission, making it universally applicable across different international transportation scenarios.
2Device complexity
If passive electronic seal is used, then structure simplicity is achieved, but data exchange capability is limited
Solution Approach 1:
The patent merges passive and active electronic seal components into a composite system. The passive RFID chip provides basic identification data exchange, while the active component with battery-powered transmission capability enhances the data exchange capability by enabling automatic warning signal transmission without requiring external power sources.
3Ease of manufacture
If single-mode electronic seal is used, then manufacturing cost is reduced, but adaptability to different country's RFID equipment is limited
Solution Approach 1:
The composite electronic seal is designed with dual functionality to be compatible with both active and passive RFID reading equipment used by different countries' customs authorities. The seal includes a passive RFID chip for basic identification and an active component with battery-powered warning signal transmission, allowing it to adapt to various international transportation scenarios.
Solution Approach 2:
The electronic seal system can dynamically switch between passive and active operating modes depending on the available reading equipment. When passive reading equipment is detected, the seal operates in passive mode for data reading. When active reading equipment is available, the seal activates its battery-powered warning signal transmission capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composite seal ensures seamless data recording and instant reporting of container status, enhancing smuggling prevention and compatibility with diverse RFID systems, while maintaining safety and flexibility during international transportation.
Implementation Method 1
the operating principle is to receive the electromagnetic power transmitted from external RFID readers, stimulate the RFID chip inside the passive electronic seal, and then use the received electromagnetic power to transmit identification data of RFID chip backwards as a responded electromagnetic signal
