Solution Overview

Problem

Existing conference systems require different touch controller devices for different software platforms, limiting flexibility and convenience, and are restricted by USB cable length to within 5 meters.

Innovation Solution

A conference system that uses an encrypted communication channel, such as Ethernet or Wi-Fi, to link a host computer with a touch controller, allowing distances beyond 20 meters and enabling USB simulation without modifying software like Microsoft Teams Rooms or Zoom Rooms, using two-way USB virtualization and display virtualization to facilitate touch control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If USB cable connection is used to link touch controller to host computer, then connection stability is improved, but connection distance is limited to within 5 meters

Engineering Contradiction:

Improveconnection stabilityVSAvoidconnection distance

Core Design Contradiction:

ReliabilityVSLength of moving object

Solution Approach 1:

The patent introduces an encrypted communication channel as an intermediary between the touch controller and host computer, replacing the direct USB cable connection. This mediator enables long-distance communication while maintaining connection stability through protocol-level reliability mechanisms and encryption for security.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical USB cable connection with a wireless or network-based encrypted communication channel. This substitution eliminates the physical distance limitations of USB cables while maintaining reliable communication through software-based connection management.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If different touch controller devices are used for different software platforms, then platform compatibility is improved, but device complexity increases

Engineering Contradiction:

Improveplatform compatibilityVSAvoiddevice variety

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal touch controller design that can interface with multiple conference software platforms through the encrypted communication channel. The single device achieves multi-functionality by implementing platform-agnostic communication protocols that work across different software environments.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent enables a single touch controller to adapt to different software platforms by changing communication parameters and encryption protocols rather than requiring different hardware devices. This parameter-based adaptation allows one device to serve multiple platforms.

Inventive Principle:

Principle #35Parameter changes
