Solution Overview

Problem

Conventional wireless presentation systems face inefficiencies due to slow data transmission speeds, requiring pre-installation of a mirror driver, which is time-consuming and often restricted by compatibility issues between wireless gateways and mirror drivers, hindering seamless plug-and-show functionality with USB portable disks.

Innovation Solution

A USB portable disk with integrated wireless network detecting, image capturing, and plug-and-show modules that detects wireless networks, analyzes differences between presentation frames, and compresses updates to enable direct plug-and-show functionality without pre-installation of a mirror driver, reducing transmission load and enhancing presentation speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a mirror driver is pre-installed on the computer to improve wireless presentation transmission speed and quality, then the presentation transmission efficiency is improved, but the ease of operation deteriorates due to time-consuming installation and compatibility issues

Engineering Contradiction:
Improvepresentation transmission speedVSAvoidease of use
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The USB portable disk automatically performs driver installation and system configuration when connected to the computer. The system detects the connection and autonomously completes the driver installation process without requiring user intervention, thereby maintaining high transmission speed while improving ease of operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mirror driver and necessary software components are pre-installed on the USB portable disk itself. When the disk is connected to the computer, these pre-prepared drivers are automatically deployed to the computer system, eliminating the need for manual installation and ensuring compatibility.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If a mirror driver is pre-installed to ensure compatibility between wireless gateway and computer, then the reliability of wireless presentation is improved, but the ease of operation worsens due to strict internal control and complex application processes

Engineering Contradiction:
ImprovecompatibilityVSAvoidapplication process simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs automatic compatibility detection and driver installation upon USB connection. The portable disk autonomously identifies the computer system type and installs the appropriate driver version, ensuring reliable compatibility while completely eliminating complex application processes that require administrative approval.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system detects computer system parameters (such as operating system type and version) upon connection and dynamically adjusts the driver installation process accordingly. This automatic parameter-based adaptation ensures compatibility across different system configurations without requiring manual intervention or complex approval workflows.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If complete installation of mirror driver is required before use to achieve proper data transmission, then the reliability of data transmission is improved, but the loss of time increases due to installation duration

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The mirror driver is pre-installed on the USB portable disk during manufacturing. When the disk is first connected to a computer, the driver is automatically transferred and installed on the computer system without requiring separate user installation, thereby ensuring reliable data transmission while eliminating the time loss associated with manual driver installation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system automatically detects the USB connection and initiates the driver installation process without user intervention. The installation is performed autonomously in the background, ensuring that reliable data transmission is established while minimizing the perceived time loss for the user.

Inventive Principle:
Principle #25Self-service

AI summary

A removable apparatus (25) with a plug-and-show function is applied to a wireless presentation system. The wireless presentation system includes a computer (23) and a wireless gateway (21). The computer (23) is capable of displaying plural presentation frames. The wireless gateway (21) provides ability in wireless network connection. When the removable apparatus (25) connects with the computer (23), the removable apparatus (25) can automatically analyze the difference region between the current presentation frame displaying in the computer (23) and the preceding presentation frame. The difference region is captured as an update image to be forwarded to the wireless gateway (21) through the computer. The wireless gateway (21) then reproduces a presentation frame the same as the current presentation frame in the computer (23) by integrating the update image with the preceding presentation frame. The reproduced presentation frame is then output to a display device (22) for further displaying.
