Ethernet Base USB Host Inversion for 3G Router Bridging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable 3G routers require modification of their basic architecture to switch network traffic to a fixed network, and they cannot be charged during data transmission due to the USB slave interface limitations, leading to a complex product structure and increased costs.
Innovation Solution
An Ethernet base with a USB unit, USB drive unit, and Ethernet unit that converts USB-formatted service data into Ethernet-formatted data, enabling the USB unit to function as a USB host, allowing simultaneous data transmission and charging, and supporting bridging between USB and Ethernet interfaces without modifying the 3G router's architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a USB to Ethernet chip with USB slave interface is used in the Ethernet base, then the base can be compatible with existing USB host interfaces of PC machines, but the portable 3G router cannot be charged simultaneously during data transmission and the basic architecture of the 3G router must be modified
Solution Approach 1:
The patent inverts the traditional USB host-slave relationship by making the Ethernet base the USB host and the portable 3G router the USB slave. This inversion resolves the charging conflict because the USB host (Ethernet base) can provide power to the USB slave (3G router) through the data transmission interface, eliminating the need for separate charging interfaces and modifying the 3G router's basic architecture.
Solution Approach 2:
The USB interface in the Ethernet base is designed to serve multiple functions simultaneously: it acts as a USB host for data transmission with the 3G router and as a charging interface to power the router. This multi-functionality eliminates the need for separate charging hardware, simplifying the product structure while maintaining compatibility.
2Ease of manufacture
If software transformation is added to the 3G router to make its USB interface function as a USB host, then the Ethernet base can use existing USB to Ethernet chips, but the basic architecture of the 3G router must be modified
Solution Approach 1:
Instead of modifying the 3G router to add USB host functionality through software transformation, the patent inverts the approach by making the Ethernet base the USB host. This eliminates the need to modify the 3G router's basic architecture while still enabling the use of standard USB to Ethernet chips in the base.
3Ease of operation
If a charging interface is added to both the 3G router and the Ethernet base, then simultaneous charging during data transmission is enabled, but the product structure becomes complex and costs increase
Solution Approach 1:
The USB interface in the Ethernet base is designed to serve multiple functions simultaneously: it acts as a USB host for data transmission with the 3G router and as a charging interface to power the router. This multi-functionality eliminates the need for separate charging hardware, simplifying the product structure while maintaining the ability to charge during data transmission.
Solution Approach 2:
The patent merges the data transmission function and charging function into a single USB interface connection between the Ethernet base and the 3G router. By combining these two functions that were previously required separate interfaces, the product structure is simplified and costs are reduced.

AI summary
The present invention discloses an Ethernet base, a network system, and a data forwarding method. The Ethernet base receives service data which is in a USB format and sent by a 3G router, and after converting the service data in the USB format into service data in an Ethernet format, sends the service data in the Ethernet format to a fixed network router. The Ethernet base further performs software configuration on its USB unit, so as to enable the USB unit to fulfill a hardware time sequence function of a USB host device. According to embodiments of the present invention, network traffic of the 3G router can be switched to the fixed network router without modifying basic architecture of the 3G router; and a USB interface of the Ethernet base supports charging the 3G router simultaneously in a process of data transmission.
