Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-voltage electrical connections are used for module identification and communication, then communication functionality is achieved, but safety risks and operational complexity increase
Solution Approach 1:
The patent introduces an electromagnetic field as an intermediary medium for wireless communication between modules. Instead of direct electrical connections, modules communicate through electromagnetic coupling, which eliminates the need for physical contact and associated safety risks while maintaining reliable data transmission for identification and status monitoring
Solution Approach 2:
The patent replaces the mechanical/electrical connection system with an electromagnetic field-based wireless communication system. This substitution eliminates physical contacts that could lead to thermal runaway, while achieving the same communication and identification functions through electromagnetic coupling
2Loss of information
If complex installation procedures with electrical connections are used, then module identification is achieved, but installation time and operational complexity increase
Solution Approach 1:
The patent implements self-identification functionality where modules automatically generate and exchange their identification data through wireless electromagnetic communication. Each module independently transmits its identifier and receives location-specific identifiers without requiring manual configuration or complex connection procedures, significantly reducing installation time and operational complexity
Solution Approach 2:
The patent pre-configures modules with unique identifiers during manufacturing, and the wireless communication system automatically activates and exchanges this identification information upon installation. The electromagnetic field-based system is pre-programmed to perform identification and location assignment without requiring manual intervention or complex setup procedures
3Loss of information
If physical contact methods are used for module communication, then data transmission is achieved, but battery depletion during storage and transit occurs
Solution Approach 1:
The patent replaces physical contact-based communication systems with electromagnetic field-based wireless communication. This substitution eliminates the need for activated electronic systems during storage and transit, as the electromagnetic tags remain dormant until exposed to an activating electromagnetic field, thereby preventing battery depletion during logistics operations
Solution Approach 2:
The patent extracts the communication functionality from the power system by using passive electromagnetic tags that do not require active power supply during storage. The tags are activated only when needed through external electromagnetic fields, separating the identification function from continuous power consumption and eliminating battery depletion risks during logistics
