Targeted Alarm Routing via Network Reliability Profiling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed targeted alarm systems, there is a risk of alarm message delivery failure or delay due to variability in network infrastructure and terminal device reliability, which can be harmful to patients, especially when caregivers use devices with different network connections and reliability characteristics.
Innovation Solution
A targeted medical alarm system that uses a network adapter to communicate with terminal devices, sends test data to determine latency-related values, updates reliability data, and identifies the most suitable terminal device for message delivery based on this data, including factors like network reliability, caregiver workload, and location, to ensure timely and reliable alarm message delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If test data is sent to multiple terminal devices to determine reliability, then alarm message delivery reliability is improved, but system complexity and communication overhead increase
Solution Approach 1:
The system performs preliminary reliability testing by sending test data packets to terminal devices before actual alarm messages need to be delivered. This advance characterization of device reliability allows the system to build a reliability profile of each terminal device, enabling informed routing decisions without adding complexity during critical alarm delivery moments.
Solution Approach 2:
Terminal devices automatically respond to test data packets with acknowledgment data, enabling the system to self-characterize device reliability without manual intervention. The devices themselves provide the information needed for routing decisions through their response patterns, reducing the burden on system complexity.
2Measurement precision
If reliability data collection and analysis is performed for each terminal device, then message delivery accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
The system collects and analyzes reliability data in advance by processing acknowledgment data from test packets before actual alarm routing is needed. This preliminary analysis builds a cached reliability profile for each terminal device, allowing rapid routing decisions to be made during critical alarm events without time-consuming real-time analysis.
3Measurement precision
If multiple latency-related values are measured and combined to determine terminal device reliability, then routing decision accuracy is improved, but measurement and processing complexity increase
Solution Approach 1:
The system merges multiple latency-related values (round-trip message latency, acknowledgment timing, physical location data) into a single composite reliability metric for each terminal device. By combining these diverse measurements into a unified reliability characterization, the system achieves accurate routing decisions without managing the complexity of individual measurements during critical routing events.
