A KVM extender system utilizing differential transmission technology with a receiving end equipped with a switching device, including a video decoder, mouse and keyboard encoder, and switch device, separates internal and external networks, allowing computer mainframes to be placed remotely, preventing data breaches and optimizing office space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two computer mainframes are placed under office desks to connect internal and external networks, then network functionality is improved, but office space is occupied and information security is compromised
Solution Approach 1:
The system separates the computer mainframes from the office desk location, placing them in a remote computer room instead. The KVM extender divides the control functions (video output, keyboard, mouse) from the computer hosts, allowing physical segmentation of computing resources from user workspaces.
Solution Approach 2:
The KVM extender acts as an intermediary device between the remote computer mainframes and the user's office desk. It transmits video signals and input commands over differential pairs, enabling control of remote computers without physical presence at the computer location.
2Adaptability or versatility
If two computer mainframes are placed under office desks, then network connectivity is achieved, but information security deteriorates due to potential data leakage
Solution Approach 1:
The system segments the internal network and external network into completely separate physical networks. The KVM extender enables independent control of computers on different networks from a single location, eliminating the need for physical crossover cables that could leak information between networks.
Solution Approach 2:
The KVM extender serves as a secure intermediary that enables network control without direct physical connection between internal and external networks. It transmits only display and input signals, not data traffic, preventing information leakage while maintaining network connectivity.
3Area of stationary object
If computer mainframes are placed remotely in a computer room, then office space is saved, but device complexity increases due to additional extender equipment
Solution Approach 1:
The KVM extender combines multiple functions into a single device: video signal transmission, keyboard input handling, and mouse control. This integration reduces the number of separate components needed compared to implementing each function independently.
Solution Approach 2:
The KVM extender is designed to work with multiple computer mainframes simultaneously, providing universal control capability. A single extender unit can manage several remote computers, reducing overall system complexity compared to dedicated control systems for each computer.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively isolates internal networks from the internet, preventing hacker attacks and data leaks while allowing computer mainframes to be housed away from office desks, thus enhancing security and saving space.
Implementation Method 1
As the extender transmitting end and extender receiving end adopt differential transmission technology
Data Source
AI summary
The invention is KVM extender receiving end provided with switch device. It includes video decoder, mouse and keyboard encoder and switch device, the input end of video decoder is connected to switch device. The output end of mouse and keyboard encoder is connected to switch device.Advantages: it will separate the intranet and the internet of the department. It will not only prevent hacker's attack but also effectively prevent internal staff from network leak. It can place two computers into the computer room, which is far away from personal office station and save a lot of office space for each office worker.
