Innovation Solution
A method and device that load a user application module, control instruction library, and driver in a Mac operating system to create a virtual network interface, enabling data interaction through a communication pipe, with upper and lower drivers managing data packets and control instructions using TCP/UDP and IOUserClient interfaces, significantly improving downlink rates and system stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional networking by virtual serial port is used, then compatibility across multiple platforms is achieved, but uplink and downlink rates are limited and cannot meet user demands
Solution Approach 1:
The patent replaces the traditional serial port communication mechanism with a virtual network interface mechanism. Specifically, it substitutes the serial port-based data transmission with Ethernet-like network interface communication, enabling higher data rates while maintaining Mac compatibility. This substitution of communication mechanics resolves the contradiction by achieving both high speed and platform compatibility.
2Speed
If networking by virtual network interface is used, then uplink and downlink rates are improved, but implementation is limited to Windows operating system only
Solution Approach 1:
The patent implements a universal virtual network interface solution that works across multiple operating systems (Mac, Windows, Linux). By creating a cross-platform compatible virtual network interface mechanism with standardized APIs and drivers, the system achieves multi-functionality and broad OS support while maintaining high data rates. This universality principle resolves the contradiction by making the high-speed networking solution applicable to all major platforms.
3Adaptability or versatility
If driver loading is performed for all data card equipment, then networking functionality is maximized, but system complexity and potential conflicts increase
Solution Approach 1:
The patent implements preliminary driver loading and configuration actions before actual networking operations begin. The system pre-loads appropriate drivers based on equipment attributes detected upon connection, and pre-configures the virtual network interface parameters. This preliminary action approach resolves the contradiction by preparing the system state in advance, reducing runtime complexity while maximizing networking functionality.
Solution Approach 2:
The patent dynamically changes system parameters based on detected equipment attributes. When data card equipment is connected, the system detects its attributes and adjusts driver loading decisions and virtual network interface parameters accordingly. This parameter adaptation approach resolves the contradiction by making the system flexible and responsive to different equipment types while maintaining manageable complexity through automated parameter adjustment.
