Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transferring software installation procedures to medical devices are cumbersome, often requiring physical connections that can introduce malware risks and necessitate costly on-site visits by service technicians, limiting device availability.
Innovation Solution
A method and system for optically transferring a software installation procedure onto a medical device using a visual depiction encoded in an image, such as a barcode, which is provided by a transmit system and recorded by the medical device without physical contact, allowing for secure and rapid updates without direct database access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile storage device is used to transfer the installation procedure, then the installation can be performed without direct database access, but there is a risk of transferring malware and requiring physical connection
Solution Approach 1:
The patent replaces the mechanical/physical connection method (USB stick, CD/DVD) with an optical transmission method using QR codes. The installation procedure is encoded into a QR code image that can be optically scanned and transferred without physical contact, eliminating the malware risk associated with mobile storage devices while maintaining the ability to transfer software updates securely
Solution Approach 2:
The patent creates a visual copy (QR code) of the installation procedure data that can be transmitted optically. Instead of copying data to a physical storage medium, the information is encoded into an image format that can be scanned and decoded by the medical device, providing a secure copy mechanism that doesn't require physical media
2Reliability
If a service technician visits on-site to install software, then the installation can be performed securely, but it is costly and reduces device availability
Solution Approach 1:
The patent enables the medical device to perform self-updating by scanning QR codes with the installation procedure encoded. The device can autonomously retrieve and install software updates without requiring a service technician's physical presence, maintaining security through controlled optical transmission while significantly improving device availability and reducing costs
Solution Approach 2:
The installation procedure is prepared in advance as a QR code that can be scanned and executed. The update package is pre-encoded into the visual format, allowing the medical device to perform the installation locally without requiring real-time technician intervention, thus improving availability while maintaining secure update delivery
3Ease of operation
If a physical connection is made to transfer the installation procedure, then the transfer can be performed, but it is complicated to ensure no malware is transferred
Solution Approach 1:
The patent replaces physical connection methods with optical transmission using QR codes. The transfer capability is maintained through wireless optical scanning, while the security verification is simplified because the QR code format inherently provides data integrity checks and eliminates the malware risks associated with physical storage media
