Solution Overview
Problem
There is a need for a comprehensive, easy-to-use, and cost-effective system for continuous, around-the-clock monitoring of vital signs that is comfortable for users, minimizing false alarms and ensuring high usability and specificity, particularly for out-patient monitoring after surgeries or for conditions like heart arrhythmias.
Innovation Solution
A system comprising a stationary sensor under the bed mattress and a wearable tracker that uses piezoelectric or ferroelectret technology for continuous monitoring, with inductive charging, allowing seamless data transition and minimizing user discomfort, and incorporating ECG electrodes for comprehensive health data capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a wearable tracker with battery is used for continuous monitoring during waking hours, then monitoring coverage is improved, but device weight and user discomfort increase
Solution Approach 1:
The monitoring system is divided into two separate devices: a wearable tracker for daytime monitoring and a mattress sensor for nighttime monitoring. This segmentation allows the wearable device to be lightweight and comfortable while still achieving continuous monitoring coverage when combined with the mattress sensor.
Solution Approach 2:
The mattress sensor serves multiple functions: it monitors vital signs during nighttime sleep and also serves as a charging station for the wearable tracker. This multi-functionality reduces the need for separate charging infrastructure and improves overall system efficiency.
2Measurement precision
If ECG electrodes are integrated into the wearable tracker, then measurement precision of heart data is improved, but device complexity increases
Solution Approach 1:
ECG electrodes are integrated directly into the wearable tracker device, combining heart monitoring capability with the existing motion and vital sign sensors. This merging eliminates the need for separate ECG monitoring equipment and simplifies the overall system architecture.
3Ease of operation
If inductive charging is implemented in the mattress, then ease of operation is improved, but manufacturing complexity increases
Solution Approach 1:
The mattress sensor automatically detects when the wearable tracker is placed on it and initiates charging without user intervention. The system self-manages the charging process, eliminating the need for manual connection or configuration by the user.
