Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ECG devices are bulky, difficult to use, and provide limited information when using a single lead, while devices with multiple leads are less bulky but lack the ability to enhance performance.
Innovation Solution
An ECG monitor device with a detachable electrode pad that includes a first group of electrodes for limb leads and a second group of electrodes on an elastic strip, connected via a multiplexer, allowing for both single and multiple lead ECG data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional ECG devices use multiple electrodes and leads, then measurement precision and information quality are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple electrodes (at least 3 electrodes including RA, RL, and chest electrodes) into a single integrated electrode pad that contacts the patient's body at one location. This merging approach maintains the capability to generate multiple leads (including precordial leads V1-V6) while eliminating the need for separate wire connections for each electrode, thus reducing device complexity while preserving measurement precision
Solution Approach 2:
The electrode pad is designed with universal functionality to support both single-lead and multi-lead ECG configurations. The same pad can generate all 12 leads (limb leads I, II, III and precordial leads V1-V6) by selectively configuring which electrodes are active, eliminating the need for different pads for different lead configurations
2Measurement precision
If conventional ECG devices use multiple electrodes and wires, then measurement precision is improved, but ease of operation and portability worsen
Solution Approach 1:
Multiple electrodes are merged into a single adhesive pad that is applied to the patient's chest in one location. The pad contains all necessary electrodes (RA, RL, and precordial electrodes) integrated together, eliminating the need to place and wire multiple separate electrodes at different body locations, thus dramatically improving ease of operation while maintaining the ability to generate all 12 leads
Solution Approach 2:
The electrode pad is segmented into multiple functional electrode regions within a single pad structure. Each electrode (RA, RL, V1-V6) is positioned at specific locations on the pad, allowing the single pad to provide multiple lead configurations through selective electrode engagement
3Ease of operation
If single lead ECG devices are used, then device complexity and ease of operation are improved, but measurement precision and information quality deteriorate
Solution Approach 1:
The electrode pad and monitoring system are designed with universal functionality to adapt to both single-lead and multi-lead configurations. The system can selectively activate different electrode combinations to generate either a simple single-lead ECG or a comprehensive 12-lead ECG, providing both ease of operation and high measurement precision depending on clinical needs
Solution Approach 2:
The ECG monitoring system dynamically configures which electrodes are active based on the desired lead configuration. The same physical electrode pad can be dynamically reconfigured to provide different lead sets (single lead, 12 leads, or intermediate configurations) through software control, allowing the system to adapt its complexity to match clinical requirements
