Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network connection devices, such as RJ45 connectors, are large, inflexible, and prone to unstable connections due to poor signal pin contact performance, especially in high-speed networks where a single faulty pin can disrupt signal transmission.
Innovation Solution
A network connection device featuring a USB Type-C interface with a PCB board using a double-backup circuit mode and superfine network cables, allowing for reversible plug orientation and improved signal reliability, along with low-pressure injection molding for enhanced durability and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RJ45 connector is used, then network connection function is achieved, but the connector size is large and bendability is poor
Solution Approach 1:
The patent applies USB Type-C interface which serves both as a universal charging interface and network connection interface. The Type-C connector integrates multiple functions including power transmission, data transmission, and network connection, replacing the dedicated RJ45 connector. This universal interface reduces overall device size while maintaining reliable network connection through its robust contact design and reversible plug orientation.
2Reliability
If RJ45 connector with eight signal pins is used, then network signal transmission is achieved, but contact performance deteriorates with aging and single pin failure causes unstable connection
Solution Approach 1:
The patent implements a double-backup circuit mode on the PCB board where each signal line has redundant routing paths. When one contact path degrades or fails due to aging, the backup path automatically takes over, preventing connection instability. This prior cushioning against contact degradation ensures long-term reliable signal transmission without being affected by single pin failure.
Solution Approach 2:
The patent changes the interface standard from RJ45 to USB Type-C, which has different electrical and mechanical parameters including higher contact reliability, better resistance to oxidation and corrosion, and improved durability. The Type-C interface parameters are designed to maintain stable electrical contact over longer periods, addressing the aging-related contact performance deterioration.
3Ease of operation
If RJ45 connector with fixed splicing direction is used, then connection is achieved, but operational flexibility is reduced due to inability to splice forward and backward
Solution Approach 1:
The patent utilizes the asymmetric yet reversible design of USB Type-C connector which allows plug orientation flexibility. The Type-C interface has a symmetric outer shape but asymmetric internal contact arrangement that automatically adapts to either plug orientation, enabling forward and backward splicing while maintaining reliable electrical connections through proper contact alignment in both orientations.

AI summary
The present invention discloses a network connection device. The network connection device includes a plug and a socket; the plug includes network cables, an encapsulation portion and a Universal Serial Bus interface; one end of the encapsulation portion is connected with the network cables, and the other end of the encapsulation portion is connected with the USB interface; and the socket is matched with the USB interface. Compared with the existing network connection device, the plug of the network connection device provided by the present invention is disposed by adopting the USB interface and particularly a Type-C interface and may be plugged forward and backward, so the network connection device not only is plugged conveniently, but also is small and exquisite, has a stable signal and does not cause an unstable network connection due to a failure of one signal pin to affect the signal transmission.
