Solution Overview
Problem
Conventional patient monitoring systems in healthcare facilities face challenges such as high cost, limited accuracy, privacy concerns, and the need for human supervision, which can lead to inefficiencies and errors in tracking patient location and detecting potential assaults or self-harm.
Innovation Solution
A system using transducers to generate 3D point clouds for patient monitoring, analyzing patient location and secondary indicia like dwell time and vital signs, and triggering alerts without manual intervention, utilizing radar technologies like mmWave, Lidar, or ultrasound to track patient welfare and detect assaults or self-harm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video monitoring systems are used to monitor patients, then monitoring accuracy and patient safety are improved, but privacy concerns and implementation complexity increase
Solution Approach 1:
The patent replaces video monitoring systems with radar-based detection systems. The radar system uses electromagnetic waves to detect patient presence, movement, and vital signs without capturing visual images, thereby eliminating privacy concerns associated with video monitoring while maintaining monitoring accuracy through precise detection of motion and physiological parameters.
Solution Approach 2:
The patent introduces radar waves as an intermediary medium between the monitoring system and the patient. Instead of directly observing patients through video cameras, the system uses radar signals to detect and measure patient-related parameters such as movement, location, and vital signs, serving as a non-intrusive intermediary that provides monitoring data without compromising patient privacy.
2Measurement precision
If conventional patient monitoring systems are used, then location tracking is provided, but human error and the need for trained supervision increase
Solution Approach 1:
The patent implements a self-monitoring system where the radar-based system automatically detects patient location, movement, and vital signs without requiring human intervention. The system autonomously processes radar data, identifies patients through their wearable devices, tracks their movements in real-time, and alerts staff only when anomalies are detected, eliminating the need for continuous human supervision while maintaining accurate monitoring.
Solution Approach 2:
The patent replaces manual monitoring by healthcare workers with an automated radar-based electronic monitoring system. The system uses radar waves to detect and track patient parameters continuously, substituting human observation and physical monitoring with automated electromagnetic detection and digital processing, thereby eliminating human error and reducing the need for trained supervision.
3Measurement precision
If RTLS systems with increased accuracy are used, then patient location determination is improved, but cost and installation difficulty increase
Solution Approach 1:
The patent uses a single radar-based system that performs multiple functions: detecting patient presence, determining location, monitoring movement, and detecting vital signs. This multi-functional approach eliminates the need for separate high-accuracy RTLS infrastructure, wearable beacons, and video monitoring systems, thereby reducing installation complexity and cost while maintaining comprehensive monitoring capabilities.
Solution Approach 2:
The patent replaces complex RTLS systems with a simpler radar-based detection system. Instead of requiring extensive infrastructure such as anchor points, trackers, and multiple sensors, the system uses radar waves that can penetrate through materials and detect patients without specialized equipment, significantly reducing installation difficulty and system complexity while achieving accurate location and monitoring.
