Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current physiological sensing devices lack the capability to accurately and non-invasively measure blood oxygen saturation and other vital signs on the head or neck, failing to provide timely alerts for potential loss of consciousness in individuals operating under extreme conditions.
Innovation Solution
A system comprising a housing mounted on the user's exterior body surface, equipped with sensors that detect physiological parameters and transmit electrical signals, and an alert circuit that generates alarms based on detected conditions, allowing for early warning of potential crises such as loss of consciousness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are placed on fingers or foreheads to measure oxygenation, then measurement can be performed, but timely alerts for potential loss of consciousness are not provided
Solution Approach 1:
The system performs preliminary detection of physiological parameters (blood oxygen saturation, heart rate, body temperature) and predicts potential loss of consciousness before it occurs. The alert circuit generates warnings in advance, allowing users to take corrective actions before the crisis develops, thus resolving the timing issue between detection and warning.
2Loss of information
If traditional oxygen sensors are used without analysis capability, then device complexity is reduced, but the ability to analyze data and alert users of issues is lost
Solution Approach 1:
The patent combines multiple functions into a single integrated device: sensors for detecting physiological parameters, an alert circuit for analyzing the detected signals, and a warning mechanism all merged into one portable device. This integration enables comprehensive physiological monitoring and intelligent alerting without requiring multiple separate devices, thus adding analytical capability while maintaining device portability.
3Measurement precision
If multiple physiological parameters are monitored simultaneously, then detection accuracy for potential crises is improved, but device complexity increases
Solution Approach 1:
The alert circuit is designed with multi-functionality to process multiple types of physiological signals (blood oxygen saturation, heart rate, body temperature) using a single integrated processing unit. This universal design allows the system to monitor multiple parameters simultaneously without proportionally increasing device complexity, as the same circuit architecture handles different sensor inputs.
