Solution Overview

Problem

Current methods for monitoring and diagnosing idiopathic arrhythmias are inadequate due to their idiopathic nature, which makes them difficult to detect with short monitoring windows and non-real-time data analysis, leading to delayed diagnosis and increased healthcare costs, and existing wearable devices are not adapted for long-term, real-time monitoring.

Innovation Solution

A system utilizing machine learning approaches, including neural networks, to detect and predict idiopathic arrhythmias through electrocardiogram sensors, which can alert emergency services and update electronic medical records, allowing for real-time monitoring and long-term data collection with a non-invasive, cost-effective smart device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If common ECG or ambulatory ECG procedures are used for monitoring, then the monitoring can be performed with standard equipment, but the monitoring window is too short to detect idiopathic arrhythmias and data analysis is not done in real time

Engineering Contradiction:
Improvedetection accuracy of idiopathic arrhythmiaVSAvoidmonitoring duration
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The system performs preliminary data collection and processing by continuously acquiring ECG signals and pre-processing them through filtering and feature extraction. This preliminary action enables the system to have ready-to-analyze data when arrhythmia episodes occur, improving detection reliability without requiring excessively long monitoring periods.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The monitoring system operates continuously in the background, constantly acquiring and pre-processing ECG data without interruption. This continuous operation ensures that no arrhythmia episode is missed while maintaining real-time analysis capability, resolving the contradiction between monitoring duration and detection reliability.

Inventive Principle:
Principle #20Continuity of useful action

2Duration of action of moving object

If a subcutaneous Holter monitor is used, then monitoring periods of over 2 years are possible with 87% smaller size, but it is invasive, single use and expensive

Engineering Contradiction:
Improvemonitoring durationVSAvoidinvasiveness
Core Design Contradiction:
Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The system employs a disposable, non-invasive smartwatch that can be worn and then discarded or replaced. This approach eliminates the invasiveness of subcutaneous monitors while maintaining long monitoring capability through multiple uses of the same device type. The device is designed for ease of replacement rather than permanent implantation.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent replaces the mechanical/invasive subcutaneous electrode system with a non-invasive optical or surface electrode system integrated into a smartwatch. This substitution eliminates skin penetration and associated harms while maintaining monitoring functionality through alternative sensing mechanisms.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If Holter monitor is worn at patient's waist, then ECG can be recorded over 24-48 hours, but it causes nuisance to patients for sleeping and day-to-day activities

Engineering Contradiction:
ImproveECG recording capabilityVSAvoidpatient comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The monitoring device is integrated into a thin, flexible smartwatch that conforms to the wrist anatomy. This form factor is significantly less obtrusive than waist-worn Holter monitors, allowing patients to sleep and perform daily activities without nuisance while maintaining continuous ECG recording capability.

Inventive Principle:
Principle #30Flexible shells and thin films

4Measurement precision

If data is uploaded to post-processing system after monitoring period, then comprehensive analysis can be performed, but diagnosis is delayed and healthcare costs increase

Engineering Contradiction:
Improvedata analysis accuracyVSAvoiddiagnosis time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system implements real-time feedback by continuously analyzing ECG data as it is acquired and immediately notifying patients and healthcare providers when arrhythmia is detected. This eliminates the delay inherent in post-processing approaches while maintaining analysis accuracy through the same sophisticated algorithms, thereby reducing diagnosis time without sacrificing measurement precision.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary real-time analysis of ECG data during the monitoring period itself, rather than waiting for post-processing. This preliminary action enables immediate detection and notification of arrhythmias, dramatically reducing diagnosis time while the same data can subsequently undergo comprehensive post-processing analysis for confirmation and detailed characterization.

Inventive Principle:
Principle #10Preliminary action
