Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data card software is upgraded to switch port forms, then port form switching capability is improved, but maintenance cost increases
Solution Approach 1:
The patent changes the parameter of port form by sending a port form flag to the data card, which switches between modem and hilink forms without requiring software upgrades. This resolves the contradiction by achieving adaptability through parameter modification rather than software replacement.
Solution Approach 2:
The patent creates a virtual copy of software functionality by implementing port form switching through hardware-level flag manipulation. Instead of upgrading actual software, the system copies the effect of software upgrades through flag-based control, eliminating maintenance costs while maintaining switching capability.
2Adaptability or versatility
If data card software is upgraded for each port form, then port form compatibility is improved, but device complexity increases
Solution Approach 1:
The patent makes the data card universally compatible with multiple port forms (modem and hilink) through a single hardware design that responds to port form flags. The switching apparatus universally supports both forms without requiring separate software installations, reducing device complexity while maintaining compatibility.
Solution Approach 2:
The patent extracts the port form switching functionality from software and implements it through hardware-level flag manipulation. By taking out the software dependency and implementing switching through simple flag signals, the system reduces software management complexity while maintaining multi-form compatibility.
3Adaptability or versatility
If multiple data card software versions are maintained, then port form coverage is improved, but time consumption for switching increases
Solution Approach 1:
The patent prepares the data card for immediate switching by pre-configuring it to respond to port form flags. The switching apparatus can instantly change the port form by sending a flag without requiring software installation or system reconfiguration, achieving rapid switching while maintaining comprehensive port form coverage.
Solution Approach 2:
The patent implements dynamic port form switching where the data card can change its operational mode in real-time based on received flags. This dynamic capability allows instantaneous adaptation between modem and hilink forms without the time-consuming process of software installation or system restart, while maintaining coverage of multiple port forms.
Data Source
AI summary
A data card switching method is provided. The method includes acquiring, by a data card switching apparatus, a port form flag of a data card; and sending, by the data card switching apparatus, the port form flag to the data card, such that the data card switches to a corresponding port form. Also, a data card and a data card switching apparatus are provided. A data card acquires a corresponding port form flag from a data card switching apparatus, and switches to a corresponding port form according to the port form flag, such that mode switching of the data card is performed without the need to upgrade data card software, thereby reducing maintenance costs of the data card.
