Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable devices and personal trackers are unable to accurately and precisely determine physiological states such as hydration, dehydration, fitness, health, exertion readiness, fatigue, alertness, altitude sickness, tolerance to environmental conditions, and blood loss in real-time, due to limitations in measuring causal relationships between monitored physiological characteristics and overall health.
Innovation Solution
A system and method for device-based maneuver and activity state-based physiologic status monitoring, utilizing sensors to monitor postures, motions, and environmental conditions, which analyze physiological data, including skin temperature, moisture, and compensatory reserve index (CRI), to determine and display real-time physiological states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wearable devices monitor physiological characteristics (pulse, heart rate, step count), then basic health tracking is enabled, but accurate determination of complex physiological states (hydration, dehydration, fitness, health, exertion readiness, fatigue, alertness, altitude sickness, environmental tolerance, blood loss) cannot be achieved
Solution Approach 1:
The system segments the physiological monitoring function into multiple independent sensor modules, each measuring a specific parameter (skin temperature, moisture, CRI, etc.). This allows complex physiological state determination to be achieved through combination of simple, specialized measurements rather than one complex device.
Solution Approach 2:
The wearable device is designed with multi-functionality to monitor diverse physiological states using a unified sensor array and processing system. The same device can detect hydration status, dehydration, fitness level, fatigue, and other states by analyzing different sensor data patterns, eliminating the need for multiple specialized devices.
2Measurement precision
If multiple sensors are used to monitor various physiological parameters, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent combines multiple sensor types (temperature sensor, moisture sensor, CRI sensor) into a single integrated wearable device. The sensors are merged with the device's processing unit and communication module to create a unified system that analyzes combined data to determine physiological states, reducing the need for separate monitoring devices.
3Productivity
If real-time monitoring of multiple physiological states is implemented, then health management effectiveness improves, but energy consumption increases
Solution Approach 1:
The system employs periodic sampling of physiological parameters rather than continuous monitoring. The sensors take measurements at intervals, and the processing unit analyzes data periodically to detect changes in physiological states. This approach maintains effective health monitoring while significantly reducing energy consumption compared to continuous operation.

AI summary
Novel tools and techniques are provided for physiological monitoring. A method includes receiving, with a computing system, physiological data of a user, analyzing, with the computing system, the received physiological data of the user to identify at least one of one or more body states or one or more transitions between body states of the user, and determining, with the computing system, at least one physiological state of the user, based at least in part on an analysis of the identified at least one of the one or more body states or the one or more transitions between body states of the user. The method further includes sending, with the computing system and to a user device, the determined at least one physiological state of the user, and displaying, on a display screen of the user device, the determined at least one physiological state of the user.
