Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data is downloaded from the device at preset intervals via a wand or other device, then data storage and processing is simplified, but the cardiac data is not useful to identify or diagnose a condition or disorder of the patient in real-time
Solution Approach 1:
The system establishes a continuous data stream from the cardiac monitor through a wireless network to a remote server, eliminating the discontinuous batch processing of conventional systems. Data flows continuously without interruption, allowing real-time access and immediate diagnostic intervention while maintaining simplified data handling through automated streaming.
2Productivity
If a continuous connection is established between a cardiac monitor and a cloud server for real-time streaming, then real-time remote monitoring is enabled, but data security and transmission reliability challenges increase
Solution Approach 1:
A cloud-based server acts as an intermediary between the cardiac monitor and healthcare providers. The server receives encrypted data streams from multiple devices, manages secure authentication, and distributes data to authorized users. This intermediary layer protects the continuous connection by centralizing security management and isolating the monitor devices from direct exposure to potential security threats.
3Duration of action of moving object
If dermal ECG electrodes or ICMs are used for long term monitoring, then a larger picture of patient cardiac activity is obtained, but the data is generally accessed by a medical professional after a scheduled data transmission which can be hours or days later
Solution Approach 1:
The system replaces the mechanical data download process (using a wand or physical connection) with a wireless electronic data transmission system. The cardiac monitor continuously transmits data via wireless network protocols to a remote server, eliminating the need for physical device connection and enabling instantaneous data access while maintaining extended monitoring duration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous, secure, and real-time monitoring of cardiac activity, facilitating immediate diagnosis and intervention during cardiac events, and reducing the need for frequent battery replacements or recharging.
Implementation Method 1
The heart emits electrical signals as a by-product of the propagation of the action potentials that trigger depolarization of heart fibers. An electrocardiogram (ECG) measures and records such electrical potentials to visually depict the electrical activity of the heart over time.
Implementation Method 2
The sensed cardiac electrical activity is represented by PQRSTU waveforms... A wearable monitor system comprising a flexible extended wear electrode patch and a removable reusable monitor recorder, which enables continuous real-time streaming of ECG data to a cloud server via a secure wireless connection
Data Source
AI summary
A system and method for remote ECG data streaming in real-time is provided. A continuous connection is established between a cloud-based server and a physiological monitor. The physiological monitor includes at least two electrodes and is affixed to a chest of a patient or implanted within the patient. ECG data is collected via one or more of the electrodes and encrypted via a wireless interface on the physiological monitor using a secret key stored on the physiological monitor. The encrypted ECG data is transmitted from the cloud-based server and received on a computing device in real-time.
