Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wired connections (CAN bus) are used for device configuration, then configuration capability is achieved, but device complexity and cost increase
Solution Approach 1:
The patent replaces the mechanical wired connection system (CAN bus) with a wireless NFC-based configuration system. The NFC module enables configuration data transmission through electromagnetic fields, eliminating the need for physical wiring between devices while maintaining configuration capability.
Solution Approach 2:
The patent introduces an NFC module as an intermediary component that enables wireless configuration data exchange. This intermediary allows configuration to occur without direct wired connections between the control unit and configuration devices, reducing wiring complexity.
2Ease of operation
If wired connections (CAN bus) are used for device configuration, then configuration capability is achieved, but cost increases
Solution Approach 1:
The patent replaces expensive wired connection infrastructure (CAN bus) with cost-effective wireless NFC technology. The NFC module provides configuration capability at lower cost by using electromagnetic field communication instead of requiring complex wired networking hardware.
3Device complexity
If NFC communication is used for device configuration, then wiring complexity is reduced, but data security risks increase
Solution Approach 1:
The patent implements preliminary authentication actions before allowing configuration data transmission via NFC. The control unit verifies the identity and authorization of the configuration device before accepting configuration commands, preventing unauthorized access and ensuring data security.
Solution Approach 2:
The patent employs feedback mechanisms where the control unit responds to NFC configuration attempts with authentication status information. This feedback loop allows the system to reject unauthorized configuration requests and only accept valid configuration data, maintaining security while enabling wireless operation.
4Ease of operation
If configuration data is transmitted via NFC, then ease of operation is improved, but susceptibility to unauthorized access increases
Solution Approach 1:
The patent performs preliminary authentication checks before enabling NFC configuration data transmission. The control unit verifies that the NFC device is authorized to perform configuration operations, preventing unauthorized access while maintaining the ease of wireless configuration operation.
