Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the position of a transitional lead in electrocardio diagnosis are not accurate, relying on the ratio of R-wave to S-wave amplitudes which does not provide precise positioning.
Innovation Solution

Engineering Contradiction Analysis
1Ease of operation
If the ratio of R-wave amplitude to S-wave amplitude is used to determine transitional lead position, then the method is simple to implement, but the positioning accuracy is insufficient
Solution Approach 1:
The patent changes the parameter from using only R-wave/S-wave ratio to using the sum of R-wave and S-wave amplitudes. This parameter transformation enables more precise positioning by capturing the absolute amplitude values rather than just their ratio, thereby resolving the contradiction between simplicity and accuracy.
Solution Approach 2:
The patent introduces a new dimension of analysis by considering both R-wave and S-wave amplitudes simultaneously as additive components rather than multiplicative ratio. This dimensional expansion from single-ratio to dual-component summation provides additional information for accurate transitional lead positioning.
2Device complexity
If only R-wave to S-wave amplitude ratio is calculated, then the calculation process is simple, but the positioning precision is not high enough
Solution Approach 1:
The patent merges the calculation of R-wave amplitude and S-wave amplitude into a unified summation process. By combining both amplitude measurements and their sums across multiple leads, the system achieves high positioning precision while maintaining relatively simple calculation logic through consolidation.
Solution Approach 2:
The patent applies a consistent calculation pattern (summing R and S amplitudes) across all chest leads V1-V6. This replicated approach ensures uniform processing and maintains simplicity in the calculation methodology while achieving precise positioning results through systematic application.
