Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 12-lead electrocardiograph devices require 10 electrodes, making them expensive and inaccessible for frequent monitoring, especially in non-hospital settings, while 2-electrode devices lack the diagnostic information provided by 12-lead ECGs.
Innovation Solution
A two-electrode electrocardiograph device with control circuitry and a data transmission module, used in conjunction with a portable computing device, measures and calculates electrocardiogram signals to replicate a 12-lead ECG by sequentially placing electrodes at predetermined positions on the body, aligning and displaying limb and augmented leads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 10 electrodes are used for conventional 12-lead ECG, then diagnostic information quality is improved, but device cost and complexity increase
Solution Approach 1:
The patent segments the 12-lead ECG measurement process into multiple sequential 2-lead measurements. Instead of using all 10 electrodes simultaneously, the system performs multiple measurements with only 2 electrodes at a time, sequentially capturing different lead configurations. This segmentation allows reconstruction of full 12-lead ECG data from simplified individual measurements, reducing device complexity while maintaining diagnostic quality.
Solution Approach 2:
The patent creates computational copies of the traditional 12-lead ECG measurement process. By using algorithms to calculate and reconstruct the full 12-lead ECG from limited 2-lead measurements, the system produces a complete ECG report without physically requiring all 10 electrodes. This copying approach through mathematical reconstruction maintains measurement precision while reducing hardware complexity.
2Measurement precision
If 10 electrodes are used for conventional 12-lead ECG, then diagnostic information quality is improved, but accessibility and cost-effectiveness deteriorate
Solution Approach 1:
The patent employs disposable or reusable 2-electrode patches that are inexpensive and can be easily manufactured. These simple electrode patches replace the need for expensive, complex 10-electrode systems. The low-cost 2-electrode design makes the device accessible for frequent monitoring and home use, while algorithms reconstruct the full diagnostic information, achieving cost-effectiveness without sacrificing measurement precision.
Solution Approach 2:
The patent uses computational algorithms to copy and reconstruct the full 12-lead ECG information from simplified 2-lead measurements. This mathematical reconstruction allows the system to provide complete diagnostic information using only minimal hardware, dramatically reducing manufacturing costs and improving accessibility while maintaining measurement precision.
3Ease of manufacture
If 2 electrodes are used for simplified ECG, then device cost and accessibility are improved, but diagnostic information completeness deteriorates
Solution Approach 1:
The patent segments the ECG measurement into multiple sequential configurations using the same 2 electrodes. By systematically positioning the electrodes in different locations and orientations, the system captures multiple lead perspectives. This segmentation strategy ensures that all necessary diagnostic information is collected through repeated measurements, preventing information loss despite using only 2 electrodes.
Solution Approach 2:
The patent employs periodic action by performing multiple sequential measurements at different time points and electrode configurations. The system repeatedly measures ECG signals with the 2 electrodes in various positions, accumulating sufficient data to reconstruct complete 12-lead information. This periodic measurement approach ensures no diagnostic information is lost while maintaining the simplicity of 2-electrode hardware.
