Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional KVM systems are complex and often restrict users from using multiple input devices like mice, keyboards, flash drives, and external hard disks simultaneously due to limitations in USB channel management, requiring multiple extenders and complex configurations.

Innovation Solution

A splitter module that uses two USB ports to connect to a computer host, splitting USB signals into HID device signals and high-speed signals, allowing simultaneous use of multiple input devices by transmitting these signals through separate ports to a KVM switch.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple extenders are used to provide more USB channels, then more input devices can be connected simultaneously, but the KVM system becomes more complex

Engineering Contradiction:

Improvenumber of input devices that can be used simultaneouslyVSAvoidKVM system configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the USB signal into different types (HID device signals and high-speed non-HID signals) and routes them through separate USB ports. This segmentation allows the single extender to handle multiple device types simultaneously without requiring multiple separate extenders, thus reducing system complexity while maintaining versatility

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent makes the single extender universal by enabling it to handle both HID devices (mouse, keyboard) and non-HID devices (flash drive, external hard disk) through the same connection. The signal splitting mechanism allows one extender to perform multiple functions that would traditionally require multiple separate extenders

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If traditional USB channel management is used, then device connectivity is maintained, but multiple input devices cannot be used simultaneously

Engineering Contradiction:

Improvesimultaneous use of multiple input devicesVSAvoiddevice configuration simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments USB signals into HID device signals and high-speed non-HID signals, routing them through separate USB ports. This segmentation enables multiple input devices to operate simultaneously without complex configuration, as the signal separation is handled automatically by the extender's internal processing unit

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The extender's processing unit automatically identifies and separates different types of USB signals without requiring manual configuration. The system self-manages the signal routing based on device type, making the system easier to operate while enabling simultaneous multi-device usage

Inventive Principle:

Principle #25Self-service

AI summary

Disclosed are a splitter module and a transmission extender having the same. The splitter module comprises a processing unit, a first USB port, a second USB port and a third USB port. An extender is electrically connected to a plurality of input devices through a hub. The extender transmits a USB signal to the third USB port of the splitter module through a USB port. The processing unit processes the USB signal by splitting it into a HID signal and a high speed signal not from any HID device. After that, the HID signal is transmitted to the KVM switch through the first USB port, and the high speed signal not from any HID device is transmitted to the KVM switch through the second USB port.
