Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
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
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.
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.

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.
