Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies lack a convenient and effective method for continuous monitoring and prediction of heart diseases, particularly atrial fibrillation, which can lead to sudden death, due to bulky electrocardiography devices and failure to detect arrhythmias in a timely manner.
Innovation Solution
An artificial-intelligence enabled finger-ring device that uses a light source and receiver to capture response light signals from a user's finger, processing time-domain and frequency-domain indices to analyze heart disease risks and provide early warnings through a communication-transmission block to external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional electrocardiography devices are used to monitor heart disease, then measurement precision is improved, but device complexity and ease of operation deteriorate due to bulky size and requirement for professional assistance
Solution Approach 1:
The patent replaces conventional bulky electrocardiography devices with a miniaturized finger-ring device that uses optical detection (light source and light receiver) instead of mechanical/electrode-based systems. This substitution enables the device to be worn independently on a finger without requiring professional assistance, while still achieving accurate heart disease monitoring through photodetection of blood flow changes.
Solution Approach 2:
The monitoring function is segmented into a compact finger-ring device that can be independently worn and removed by users. The device separates the detection, processing, and warning functions into an integrated miniaturized system, allowing users to perform monitoring themselves without needing bulky conventional equipment or professional assistance.
2Measurement precision
If conventional electrocardiography devices are used to monitor heart disease, then measurement precision is improved, but device complexity worsens due to bulky size and inability to wear for 24 hours
Solution Approach 1:
The patent replaces bulky conventional electrocardiography equipment with a miniaturized optical detection system in a finger-ring format. This substitution dramatically reduces device size and complexity, enabling 24-hour continuous wear while maintaining detection accuracy through optical measurement of blood flow characteristics.
Solution Approach 2:
The patent transitions from traditional chest-attached electrocardiography to a finger-based optical monitoring approach. This dimensional change in measurement location and method enables miniaturization and continuous wear, as the finger provides accessible blood flow detection points that can be monitored optically without requiring large equipment.
3Productivity
If electrocardiography is performed at fixed intervals, then productivity is improved, but reliability worsens due to failure to detect paroxysmal atrial fibrillation
Solution Approach 1:
The patent implements continuous monitoring capability through the finger-ring device that can operate 24 hours without interruption. The device continuously detects blood flow changes and analyzes heart rhythm, ensuring that paroxysmal atrial fibrillation episodes are captured regardless of when they occur, thereby improving reliability while maintaining productivity through automated analysis.
Solution Approach 2:
The device incorporates real-time analysis of detected signals with immediate feedback through warning functions. When atrial fibrillation or other arrhythmias are detected, the system provides timely alerts to users and medical personnel, ensuring that paroxysmal episodes are reliably identified and addressed promptly, thereby improving both detection reliability and response effectiveness.

Data Source
AI summary
An artificial intelligent finger-ring device for pre-alarming heart disease, which may detect heart diseases and emit alerts even before heart disease symptoms happen, comprises a detection block, a communication-transmission block, a control block and a power block. The detection block includes a light source emitting green light and a light receiver receiving a response light signal. The green light is incident to a finger of a user and reflected to form the response light signal. The communication-transmission block transmits the response light signal to an external device and receives an analysis result from the external device. The analysis result which is acquired by analyzing the response light signal includes a time-domain index and a frequency-domain index applicable to monitor heart diseases. The control block receives the analysis result and determine whether to emit alerts. The power block supplies electric power to the detection block, the communication-transmission block and the control block.
