Solution Overview

Problem

Existing AV systems in enterprise environments face challenges in real-time control due to the absence of AV gateway devices in every room, and creating a VPN for remote access is resource-intensive and time-consuming.

Innovation Solution

A web proxy shuttle system allows users to control AV equipment remotely through a web browser, using a web proxy to securely transmit control commands to an AV gateway without requiring extensive enterprise resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a VPN is created to allow remote access to the AV gateway, then remote access capability is improved, but implementation time and enterprise resource consumption increase significantly

Engineering Contradiction:

Improveremote access capabilityVSAvoidimplementation time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent introduces a web server as an intermediary component that sits between the user's web browser and the AV gateway. The web server receives control commands from users via web browsers, translates them into appropriate control protocols, and forwards them to the AV gateway. This intermediary approach enables remote access without requiring complex VPN infrastructure, as the web server can be accessed through standard web protocols through the firewall.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the remote access functionality from the traditional VPN approach and implements it through a standalone web server application. Instead of requiring a full VPN infrastructure, the solution extracts only the essential remote control capability and implements it through a simplified web-based interface that can be accessed through standard web browsers without VPN connectivity.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If a VPN is created to allow remote access to the AV gateway, then remote access capability is improved, but enterprise resource consumption increases

Engineering Contradiction:

Improveremote access capabilityVSAvoidenterprise resource consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The web server acts as a resource-efficient intermediary that handles all remote access requests through standard web protocols. Instead of maintaining expensive VPN infrastructure and dedicated network resources, the web server uses existing web server capabilities and can be hosted on standard hardware, significantly reducing enterprise resource consumption while maintaining remote access functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs a lightweight web server application that can be deployed on existing infrastructure without requiring dedicated VPN hardware or extensive network resources. The web-based control interface uses standard web technologies that are already widely available, eliminating the need for expensive specialized remote access infrastructure.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If AV gateway devices are installed in every room for real-time control, then control availability is improved, but system cost increases

Engineering Contradiction:

Improvereal-time control availabilityVSAvoidnumber of gateway devices

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The web server provides a universal access point that can control multiple AV gateways and equipment across different rooms through a single interface. Instead of requiring dedicated gateway devices in every room, the web server consolidates control functionality, allowing users to access and control AV equipment in any room through the centralized web interface, reducing the total number of gateway devices needed.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If direct access to AV gateway is allowed for remote control, then control functionality is improved, but network security is compromised

Engineering Contradiction:

Improveremote control functionalityVSAvoidnetwork security risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The web server serves as a secure intermediary that mediates all communication between external users and internal AV gateways. It implements authentication, authorization, and protocol translation, ensuring that only authorized commands reach the AV gateway. This intermediary layer protects the internal network from direct external access while maintaining full remote control functionality through the secure web interface.

Inventive Principle:

Principle #24Intermediary (Mediator)
