Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If automatic analysis is performed during real-time collection, then analysis speed is improved, but noise interference and electrode issues cause repeated re-recording reducing reliability

Engineering Contradiction:
Improveanalysis speedVSAvoidwaveform quality
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system performs preliminary actions by automatically extracting multiple candidate waveform segments and preparing analysis results before the user needs to review them. The ECG analyzing apparatus extracts a plurality of candidate segments from collected waveforms, calculates analysis results for each candidate, and displays them in advance, so when the user views the results, the work is already completed and they only need to select from pre-prepared options.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the user manually selects appropriate waveform segments for recording, then waveform quality is improved, but the operation becomes cumbersome and complex

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The ECG analyzing apparatus performs self-service by automatically extracting multiple candidate waveform segments, calculating analysis results for each candidate, and displaying them with their analysis outcomes. The system serves itself by autonomously completing the waveform selection and analysis work that would otherwise require complex manual user operations, providing users with ready-to-select results.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary actions by automatically extracting multiple candidate waveform segments and preparing analysis results before the user needs to review them. The ECG analyzing apparatus extracts a plurality of candidate segments from collected waveforms, calculates analysis results for each candidate, and displays them in advance, so when the user views the results, the work is already completed and they only need to select from pre-prepared options.

Inventive Principle:

3Adaptability or versatility

If multiple waveform segments are displayed for selection, then user choice is improved, but display complexity increases

Engineering Contradiction:
Improvewaveform selection flexibilityVSAvoiddisplay complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display screen is segmented into distinct functional areas: a waveform display area showing multiple candidate waveform segments, and a separate analysis result display area showing the calculated results for each candidate. This segmentation allows the system to present multiple waveform options with their corresponding analysis results in an organized, non-overlapping manner that reduces display complexity while maintaining selection flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system separates the display of waveform data and analysis results into different spatial dimensions or areas on the screen. By displaying waveforms in one area and their corresponding analysis results in another area, the system avoids cluttering a single space, thereby reducing perceived display complexity while still providing comprehensive information for multiple waveform candidates.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Electrocardiographic waveforms for a plurality of candidate segments (analysis unit segments) are extracted from collected electrocardiographic waveforms and the extracted electrocardiographic waveforms for the plurality of candidate segments (analysis unit segments) are displayed on one screen. As a result, a user can determine, e.g., what candidate segment (analysis unit segment) analysis results to view while simultaneously viewing the electrocardiographic waveforms for the plurality of candidate segments (analysis unit segments) and which candidate segment to record, without any switching between screens, and as a result can perform appropriate electrocardiogram analysis using a simple operation.
