Modular Wireless ECG Patch for 12-Channel Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional patch-type wireless electrocardiogram monitoring devices have limitations such as small size, which restricts the number of electrodes that can be attached, leading to incomplete electrocardiogram measurements, and poor signal quality due to electrode placement on the upper arm, resulting in decreased reliability and limited usability.
Innovation Solution
A miniaturized patch-type wireless electrocardiogram monitoring device with a modular design, featuring a patch portion with electrodes on both the chest and hand/finger surfaces, allowing for easy attachment and detachment, and a module portion for signal processing and wireless communication, which guides accurate electrode placement using a smart device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the patch size is reduced to improve portability and ease of attachment, then the number of electrodes that can be attached is limited, but this results in incomplete electrocardiogram measurements and reduced measurement precision
Solution Approach 1:
The device is divided into two separate detachable patches: a chest patch containing six electrodes for chest electrode positions, and a hand patch containing four electrodes for hand electrode positions. This segmentation allows each patch to be optimized for its specific function while maintaining the capability for complete 12-channel electrocardiogram measurements when both patches are used together.
Solution Approach 2:
The invention distributes electrodes across two different body locations (chest and hand) rather than concentrating all electrodes on a single patch. This spatial distribution in another dimension enables complete electrocardiogram measurement capability without requiring a large single patch, thus resolving the contradiction between patch size and measurement completeness.
2Volume of moving object
If electrodes are placed on the upper arm to reduce patch size, then portability is improved, but signal quality deteriorates due to increased noise and decreased signal intensity
Solution Approach 1:
The device separates chest electrodes and hand electrodes into different detachable patches, allowing optimal placement of hand electrodes on the hand rather than the upper arm. This segmentation enables signal quality optimization while maintaining compact patch design.
Solution Approach 2:
The invention places hand electrodes specifically on the hand (distal to the upper arm) to optimize signal quality. This local optimization of electrode placement ensures reliable signal acquisition while maintaining the benefit of reduced patch size.
3Ease of operation
If the patch is designed to be compact for ease of attachment, then ease of operation is improved, but the device complexity increases due to modular design requirements
Solution Approach 1:
The device is segmented into detachable chest and hand patches, which simplifies attachment and removal operations. Users can attach only the necessary patch or both patches separately, improving ease of operation despite the modular design.
Solution Approach 2:
The detachable patch design provides multi-functionality: the chest patch can be used alone for basic monitoring, the hand patch can be used alone for specific measurements, or both can be used together for complete 12-channel electrocardiogram measurements. This universality justifies the modular design while enhancing operational flexibility.
