Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hemorrhage from vascular injuries in the proximal extremities, pelvis, and abdomen is challenging to triage in the field, especially in combat or mass casualty situations, due to delays in notifying appropriate parties of the injury and its nature.
Innovation Solution
A bracelet equipped with a geolocation sensor and various physiological sensors, such as heart rate, oxygen saturation, and impact detection sensors, which can be activated upon contact with the user or deformation of the bracelet, allowing for real-time monitoring and transmission of health and injury data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors are integrated into the bracelet to monitor physiological parameters and detect injuries, then the ability to relay critical information is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple sensors (geolocation, heart rate, oxygen saturation, blood pressure, respiratory rate, temperature, impact detection, movement) into a single integrated bracelet device. This merging approach allows the bracelet to monitor comprehensive physiological parameters and detect injuries while reducing the need for multiple separate devices, thereby improving information relay capability without proportionally increasing complexity.
Solution Approach 2:
The bracelet is designed as a multi-functional device that simultaneously performs geolocation tracking, physiological monitoring, injury detection, and data transmission. By making the bracelet universal in its functionality, the patent eliminates the need for separate specialized devices, improving the reliability of critical information relay while managing device complexity through consolidation.
2Speed
If the bracelet continuously monitors physiological parameters to enable timely intervention, then the speed of information transmission is improved, but the energy consumption increases
Solution Approach 1:
The bracelet employs periodic sampling of physiological parameters rather than continuous monitoring at maximum frequency. The system adjusts the monitoring frequency based on the operational context, using lower sampling rates during normal conditions and increasing to higher rates only when anomalies are detected or during critical events. This periodic action maintains timely information transmission while significantly reducing overall energy consumption compared to continuous high-frequency monitoring.
Solution Approach 2:
The bracelet includes an impact detection sensor that automatically triggers enhanced monitoring and data transmission when injury is detected. This self-service mechanism allows the device to maintain high-speed information transmission only when necessary (upon injury detection) rather than continuously, thereby reducing baseline energy consumption while preserving the capability for rapid response when needed.
