Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If intelligent mobile terminals use simple connection interfaces, then device complexity is reduced, but adaptability to support multiple data transmission modes and interfaces deteriorates
Solution Approach 1:
The portable data card integrates multiple functions including USB data transmission, card reader interface, and OTG mode support within a single compact device. The interface module can connect to different types of external devices (smartphones, tablets, PCs) through different interfaces (USB, card reader), enabling one device to serve multiple purposes and eliminating the need for separate accessories for each function.
2Adaptability or versatility
If multiple data transmission accessories are carried to meet different demands, then adaptability is improved, but user burden and inconvenience increase
Solution Approach 1:
The patent merges multiple data transmission functions and interfaces into a single portable data card device. Instead of carrying separate USB adapters, card readers, and OTG cables, users only need this one integrated device that combines all necessary functionality, thereby reducing baggage burden and simplifying operations.
3Adaptability or versatility
If a multifunctional portable device is developed, then adaptability and ease of operation are improved, but device complexity increases
Solution Approach 1:
The portable data card is divided into distinct functional modules: a main control module for coordination, a gear selection module for mode switching, a data transmission module for actual data transfer, an interface module for external connections, and a storage module for data storage. This modular segmentation allows each component to perform its specific function independently while working together as an integrated system, managing complexity through organization.
Solution Approach 2:
The device incorporates a gear selection module that enables dynamic switching between different data transmission modes (USB mode, card reader mode, OTG mode) based on the connected device and user needs. This dynamic adaptability allows the same hardware to reconfigure its functionality, improving versatility without requiring separate physical devices for each function.

AI summary
A multifunctional portable data card and a data transmission method are provided. The data card includes a main control module, a gear selection module, a data transmission module, an interface module and a storage module. The main control module detects a gear selection signal generated by the gear selection module, and sends a corresponding operation command to the data transmission module according to a working mode corresponding to the gear selection signal; the data transmission module performs data transmission in the data transmission mode or the OTG data processing mode after receiving the operation command; the interface module provides a port for interaction between the multifunctional portable data card and an external device; and the data card further includes the storage module.
