Multimedia System Wireless Device Switching via Web Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia systems for multiple user interactions are cumbersome and costly, with limited functionality, as they require mechanical switches or disks for device switching and often rely on unreliable wireless connections that are non-intuitive and require software installation, leading to compatibility issues and high traffic disruptions.
Innovation Solution
A system featuring a touch screen display with a computer that allows multiple users to log in, associate scanned data as identifying information, and manage sessions independently, enabling secure and intuitive wireless connectivity through built-in streaming functions, allowing multiple devices to share content on a single display without the need for additional software downloads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical switches or disks are used for device switching, then device switching functionality is achieved, but device complexity and cost increase
Solution Approach 1:
The patent replaces mechanical switching devices (switches and disks) with a software-based system that uses a web browser and web server architecture. The display computer runs a web server that receives requests from mobile devices and manages content display through software control, eliminating the need for physical switching hardware.
Solution Approach 2:
The web browser-based interface serves multiple functions: it acts as the user interface for device selection, the control mechanism for switching content sources, and the display configuration interface. This single universal interface replaces multiple specialized mechanical components.
2Ease of operation
If wireless connections are used for mobile device connectivity, then ease of operation improves, but reliability and compatibility deteriorate
Solution Approach 1:
The patent introduces a web server as an intermediary between mobile devices and the display system. Mobile devices connect wirelessly to the web server, which then manages the connection to the display computer. This intermediary layer provides a standardized protocol that improves compatibility and reliability while maintaining wireless ease of use.
Solution Approach 2:
The system separates the connection management function into distinct layers: wireless connectivity handling, web protocol processing, and display content management. This segmentation allows each layer to be optimized independently, improving overall system reliability while maintaining ease of operation.
3Ease of operation
If software installation is required for wireless connectivity, then connection functionality is achieved, but loss of time and ease of operation worsen
Solution Approach 1:
The system uses the mobile device's existing web browser, which is already installed and functional. The display computer runs a web server that automatically serves the connection interface. Users simply open their browser and interact with the web interface—no additional software installation is required on either device.
Solution Approach 2:
Instead of installing proprietary software, the system uses the universally available web browser as a copy of the required functionality. The browser's existing capabilities are leveraged to provide the connection and control interface, eliminating installation time while maintaining full functionality.
4Adaptability or versatility
If multiple devices are connected to a single display, then adaptability improves, but device complexity increases
Solution Approach 1:
The web server acts as an intermediary that manages multiple device connections through a single standardized interface. It receives requests from any number of mobile devices, processes them through the same web protocol, and manages display switching without requiring complex individual handling of each device.
Solution Approach 2:
The web-based interface provides universal control for all devices simultaneously. The same browser interface can be used by multiple users to select devices, control playback, and manage display settings, eliminating the need for separate control mechanisms for each device.
