Wireless Video Wall Hub for Dynamic Multi-Display Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies are either too small and mobile but lack detail, or too large and static, limiting their usability for shared viewing and mobility.
Innovation Solution
A hub system that connects multiple digital video sources to displays wirelessly or via cables, allowing for the creation of a dynamic video wall with displays of varying sizes and aspect ratios, enabling flexible and mobile multimedia sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If large display technologies like projectors and televisions are used to provide detailed viewing, then viewing detail is improved, but mobility and ease of setup are worsened
Solution Approach 1:
The system divides a large display into multiple separate display devices (smartphones, tablets, laptops) that can be independently positioned and connected. Each display shows a portion of the overall image, allowing the user to assemble a custom video wall using existing portable devices rather than requiring a single large permanent installation.
Solution Approach 2:
The hub device serves multiple functions: it acts as a signal distributor, configuration server, and coordination center. It connects to various types of display devices via different interfaces (HDMI, DisplayPort, wireless), making the system adaptable to different display technologies and configurations without requiring specialized hardware for each scenario.

If multiple display devices are combined to create a large video wall, then viewing area and detail are improved, but system complexity and setup difficulty are worsened
Solution Approach 1:
The hub device serves as an intermediary between the video source and multiple display devices. It automatically manages signal distribution, synchronizes timing, handles different display resolutions and aspect ratios, and coordinates the individual displays into a unified virtual screen. This mediator simplifies the overall system architecture by centralizing the complexity in one device.
Solution Approach 2:
The system dynamically adjusts parameters such as display resolution, aspect ratio, and signal timing based on the specific display devices connected. The hub detects the capabilities of each display and automatically configures the video signal parameters to optimize the presentation on that particular device, eliminating manual configuration requirements.
3Area of stationary object
If fixed video wall installations are used to provide large display area, then viewing area is improved, but adaptability and mobility are worsened
Solution Approach 1:
The video wall configuration is dynamic rather than fixed. Users can add, remove, or reposition display devices at any time, and the hub automatically reconfigures the video distribution to accommodate the changed arrangement. The virtual screen boundaries and display portions are dynamically adjusted based on the current physical configuration of display devices.
Solution Approach 2:
The system transforms the physical arrangement of display devices into a virtual two-dimensional coordinate system. The hub maps the physical positions of displays to virtual screen coordinates, allowing flexible spatial arrangements that can be easily reconfigured without physical reinstallation. This dimensional abstraction enables mobility while maintaining large display area.

AI summary
The system is comprised of a hub which in turn is made of a housing, at least one video input port, at least two video output ports, a digital card enabling communication between a computer and at least one display without a direct physical connection and a processor. The hub is used to make a video wall.
