Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection interface switching devices require numerous wires for connecting multiple portable devices, are not adaptable to changing port specifications, and often only support single-screen output, making them costly and inefficient for multi-screen setups.
Innovation Solution
A connection interface switching device with a controller, memory module, and storage module that establishes a communication channel between portable devices and I/O peripherals via a single I/O connection line, allowing multiple devices to share peripherals and support multiple screens through universal ports like USB, VGA, DVI, HDMI, or DisplayPort, with a default control program for switching and hot key operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional switches use one-to-one connection of all ports for each personal computer, then reliable connection is achieved, but the quantity of connection wires increases and material cost increases
Solution Approach 1:
The patent applies universality by using a single I/O connection line that can dynamically serve multiple portable devices through communication channel switching. The switch device establishes communication channels with multiple portable devices via a single connection line, allowing one line to perform multiple functions by switching which device it connects to, thereby reducing the quantity of connection wires while maintaining reliable connections.
2Reliability
If conventional switches use multiple connection wires for each device, then stable connection is achieved, but the field application becomes complicated
Solution Approach 1:
The single I/O connection line serves multiple devices through dynamic channel switching, simplifying field application. Users only need to connect each portable device to the switch via one connection line, and the switch automatically manages connections through communication channels, making field application straightforward while maintaining stable connections.
Solution Approach 2:
The switch device acts as an intermediary between multiple portable devices and I/O peripherals. It establishes communication channels and manages switching between devices, simplifying the overall system complexity. The controller within the switch coordinates channel establishment and switching based on switch instructions, making the system easier to operate in field applications.
3Adaptability or versatility
If conventional switches are designed for specific port specifications, then compatibility with current devices is achieved, but adaptability to updated port specifications is lost
Solution Approach 1:
The switch device uses universal I/O ports (such as USB ports) that can interface with multiple types of portable devices through communication protocols. The controller establishes communication channels based on switch instructions from different devices, allowing the switch to adapt to various port specifications while maintaining reliable connections through protocol-based communication rather than hardwired connections.
4Ease of operation
If conventional switches provide single-screen input or switching, then simple control is achieved, but multi-screen output requirement cannot be met
Solution Approach 1:
The switch device establishes separate communication channels for different functions including video output and I/O control. The I/O peripheral port includes video output ports connected to display devices and I/O control ports connected to control devices like keyboards and pointing devices. This allows the simple switch operation to control multiple screens and peripherals simultaneously while maintaining ease of operation through the same switching mechanism.
