Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional driver and application software installation methods are used, then the data card can provide data, voice and short message services, but the installation steps become cumbersome and installation time increases to several minutes to ten minutes
Solution Approach 1:
The patent extracts the application software installation step from the traditional driver installation process. By using the MBIM protocol, the data card can communicate with the terminal without requiring separate application software installation, effectively removing this time-consuming step while maintaining service provision capability through protocol-level integration
Solution Approach 2:
The MBIM protocol acts as an intermediary layer between the data card and the terminal operating system. This protocol enables direct communication and service provision without requiring traditional driver and application software installation, thereby reducing installation time while ensuring reliable service delivery
2Reliability
If traditional driver and application software are installed, then the data card can operate, but compatibility problems occur across different terminal manufacturers and types
Solution Approach 1:
The MBIM protocol provides a universal communication interface that works across different terminal manufacturers and types. By standardizing the interaction protocol at the system level, the data card achieves broad compatibility without requiring manufacturer-specific drivers or application software, thereby improving adaptability while maintaining operation capability
3Ease of operation
If application program is installed, then the data card can be operated, but registry modification and incomplete uninstallation increase operating system garbage
Solution Approach 1:
The patent removes the need for separate application program installation by integrating communication functionality directly into the MBIM protocol implementation. This eliminates registry modifications and incomplete uninstallation issues associated with traditional application software, thereby reducing system garbage while maintaining ease of operation through protocol-level integration
4Ease of manufacture
If driver and application software installation packages are integrated in data card storage, then installation can be performed, but limited resources of the data card are occupied
Solution Approach 1:
The patent extracts the installation packages from the data card storage by utilizing the MBIM protocol, which is natively supported by modern operating systems. This eliminates the need to store driver and application software packages on the data card, thereby preserving limited storage resources while maintaining installation capability through protocol-level integration
5Ease of operation
If ECM or RNDIS protocols are used for driver-free installation, then driver installation is avoided, but communication efficiency is low in high speed networks such as HSPA and LTE
Solution Approach 1:
The patent changes the communication protocol parameter from ECM or RNDIS to MBIM. This parameter change enables driver-free installation while simultaneously improving communication efficiency in high-speed networks like HSPA and LTE, as the MBIM protocol is specifically designed to handle high-speed data transmission more effectively than its predecessors
