Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all recorded electrocardiogram signals are analyzed, then comprehensive diagnostic accuracy is improved, but analysis time and computational resources increase significantly

Engineering Contradiction:

Improvediagnostic accuracyVSAvoidanalysis time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent divides the continuous electrocardiogram signal into discrete signal segments with variable window sizes. By segmenting the signal, the system can selectively analyze only certain segments rather than processing the entire continuous signal, thereby reducing analysis time while maintaining diagnostic accuracy through strategic selection of analyzable segments.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts and identifies specific signal segments that contain diagnostically valuable information while excluding segments with noise or artifacts. This extraction process allows the system to focus computational resources only on relevant portions of the electrocardiogram signal, reducing overall analysis time without compromising diagnostic reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of manufacture

If fixed window size is used for signal segmentation, then processing simplicity is improved, but adaptability to different signal conditions deteriorates

Engineering Contradiction:

Improveprocessing simplicityVSAvoidadaptability to signal conditions

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements variable window sizes for signal segmentation instead of fixed window sizes. The window size dynamically adjusts based on the characteristics of each signal segment, allowing the system to adapt to different signal conditions such as varying heart rates, noise levels, and rhythm patterns. This dynamic approach maintains processing simplicity while significantly improving adaptability.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If variable window sizes are used for segmentation, then adaptability to different signal conditions is improved, but processing complexity increases

Engineering Contradiction:

Improveadaptability to signal conditionsVSAvoidprocessing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent changes the parameter of window size from fixed to variable based on signal characteristics. By adjusting this single parameter dynamically, the system achieves adaptability to different signal conditions without introducing complex multi-parameter control mechanisms. This approach balances adaptability improvement with controlled processing complexity.

Inventive Principle:

Principle #35Parameter changes

4Quantity of substance

If noise sections are included in analysis, then complete data coverage is improved, but analysis quality deteriorates due to noise interference

Engineering Contradiction:

Improvedata coverageVSAvoidanalysis quality

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent converts the harmful effect of noise into a beneficial selection criterion. By identifying segments with noise or artifacts, the system uses these problematic segments as indicators to exclude from detailed analysis. This approach transforms noise from a quality-degrading factor into a useful filter that improves overall analysis quality while maintaining comprehensive data coverage through selective processing.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
