Peer-to-Peer Software Update Propagation in Medical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical facility equipment with embedded software faces challenges in timely and cost-effective software updates due to the large number of devices that need to be individually upgraded, leading to issues like malfunctioning equipment, security vulnerabilities, and inefficiencies.
Innovation Solution
A peer-to-peer automatic software update system where one device with updated software connects to others within range using Wi-Fi Direct or similar protocols, transferring the updates to propagate throughout the facility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual equipment is manually updated with new software versions, then software reliability is improved, but time consumption and operational complexity increase significantly
Solution Approach 1:
The system enables equipment to automatically update their own software by having them periodically check for updates and self-install when available, eliminating the need for manual intervention on each device while maintaining high reliability through automated update deployment
Solution Approach 2:
The update process is segmented into independent steps: update detection, download, installation, and verification. Each piece of equipment can independently execute these segments at its own pace, allowing parallel updates across multiple devices without requiring centralized coordination for each individual update action
2Reliability
If individual equipment is manually updated with new software versions, then software security is improved, but operational complexity increases
Solution Approach 1:
A universal update management system is implemented that can handle multiple functions: detecting updates across different equipment types, downloading software packages, managing installation processes, and verifying updates. This single system serves all equipment in the facility, reducing operational complexity despite improved security through comprehensive update management
3Ease of operation
If equipment is not updated timely, then operational simplicity is maintained, but vulnerability to security threats increases
Solution Approach 1:
The system performs preliminary actions by proactively detecting available updates and preparing installation packages before security threats can exploit vulnerabilities. Equipment automatically checks for updates at scheduled intervals and pre-downloads necessary software, ensuring security patches are applied before threats become problematic while maintaining operational simplicity through automated scheduling

AI summary
A method to be performed by a processor of a first computing device includes detecting one or more computing devices remote from the first computing device, establishing a peer-to-peer connection with a second computing device from among the one or more computing devices, comparing a first version of a software program installed on the first computing device to a second version of the software program installed on the second computing device, and upon determination that the second version of the software program is more recent than the first version of the software program, receiving second installation software associated with the second version of the software program and executing the second installation software to install the second version of the software program onto the first computing device.
