Image Transmission Device with Inaccessible Internal Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image transmission devices relying on USB mass storage for software and drivers are rendered ineffective in organizations that disable USB functionality due to safety concerns and the risk of malware, limiting their use in secure environments.
Innovation Solution
An image transmission device with an internal storage unit inaccessible to computers, utilizing a wireless communication module and a USB connector, allows portable software to be copied or downloaded from an external source, eliminating the need for pre-stored software and enabling one-button screen mirroring without exposing the device to malware risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If USB mass storage device functionality is used in image transmission device, then software and drivers can be pre-stored for easy installation, but security risks increase due to potential malware and viruses
Solution Approach 1:
The patent extracts the harmful mass storage functionality from the USB device, keeping only the essential image transmission capabilities. The device removes the mass storage driver and functionality that could introduce malware, while maintaining the ability to transmit images through alternative mechanisms that do not require pre-stored software.
2Object-affected harmful factors
If USB mass storage device is disabled in staff computers for security reasons, then malware risk is reduced, but image transmission device becomes useless
Solution Approach 1:
Instead of relying on mass storage functionality to deliver software, the patent inverts the approach by making the device completely software-free. The image transmission capabilities are built into the device hardware itself, eliminating the need for any mass storage driver or pre-stored software, thus working seamlessly in environments where USB mass storage is disabled.
3Object-affected harmful factors
If internal storage unit is made inaccessible to computer, then security is enhanced by preventing unauthorized access, but software updating becomes more difficult
Solution Approach 1:
The patent removes the requirement for software updates entirely by designing a device that does not store software on accessible storage. The image transmission functionality is implemented through hardware-based mechanisms that do not require software installation or updates, eliminating both the security risk and the update complexity.
Data Source
AI summary
An image transmission device includes a CPU, and a wireless communication module, a button, a USB connector and an internal storage unit connected with the CPU. The USB connector is inserted into a computer having a portable software. The internal storage unit is inaccessible to the computer. The portable software is copied or downloaded to the computer from an external source and executed by the computer. The wireless communication module is wirelessly connected with a receiving device. When the button is activated, a signal is transmitted to the CPU and a command is transmitted to the portable software by the CPU to execute screen mirroring control, so that images are transmitted from the computer to the receiving device through the USB connector and the wireless communication module. The safety and application diversity are effectively enhanced, and the one-button screen mirroring is realized.
