Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cardiac vector loops are displayed using traditional two-dimensional methods, then the display is simple and easy to implement, but the ability to compare cardiac information from different time periods is insufficient and diagnostic accuracy is reduced
Solution Approach 1:
The patent transitions from traditional two-dimensional display to three-dimensional visualization of cardiac vector loops. The 3D display system represents cardiac electrical activity in three-dimensional space with x, y, and z axes, allowing practitioners to view vector loops from multiple angles and perspectives. This dimensional enhancement improves diagnostic accuracy by revealing spatial relationships and temporal changes that are not apparent in 2D representations.
2Productivity
If multiple sets of ECG data from different time periods are displayed separately, then each dataset can be analyzed in detail, but the time required for comparison and diagnosis increases
Solution Approach 1:
The patent combines multiple sets of ECG data from different time periods into a single integrated three-dimensional display. Multiple cardiac vector loops representing different time points are superimposed on the same 3D coordinate system, allowing practitioners to compare cardiac electrical activity across time periods simultaneously. This merging approach enables rapid identification of changes and trends without requiring separate analysis of each dataset.
Solution Approach 2:
The display system incorporates dynamic interaction capabilities that allow practitioners to rotate, zoom, and manipulate the three-dimensional visualization of multiple cardiac vector loops. Users can dynamically adjust viewing angles and select specific time periods for closer examination, enabling efficient comparison while maintaining the ability to focus on relevant details when needed.
3Measurement precision
If cardiac vector loops are aligned without considering measurement inconsistencies, then the alignment process is simple, but diagnostic accuracy is reduced due to measurement variations
Solution Approach 1:
The patent implements an alignment process that accounts for measurement inconsistencies by using reference vectors and transformation matrices. The system calculates alignment transformations based on comparing vector loops from different time periods, automatically adjusting for measurement variations. This feedback-based alignment improves accuracy by compensating for inconsistencies while maintaining an automated process that does not require manual intervention.

AI summary
A system for comparative analysis of cardiac information including an electrocardiogram (ECG), a user interface, a memory storing instructions; and a processor configured to execute the instructions to: obtain a first set of ECG data from the ECG device, the first set of ECG data being measured from a patient during a first time period; obtain a second set of ECG data from the ECG device, the second set of ECG data being measured from the patient during a second time period distinct from the first time period; obtain a first three-dimensional (3D) object based on the first set of ECG data; obtain a second 3D object based on the second set of ECG data; and control the user interface to simultaneously display the first 3D object and the second 3D object on a same axis.
