An automatic measurement point correction method that allows operators to correct a first measurement point, record it as a reference, and use this reference to automatically correct analogous waveforms, reducing the operator's burden and facilitating quicker diagnosis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the operator visually corrects each measurement point manually, then the measurement precision is improved, but the operator's workload and time consumption increase significantly

Engineering Contradiction:
Improvemeasurement point accuracyVSAvoidcorrection time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary automatic analysis to determine measurement points, then uses operator correction of a reference waveform to automatically correct analogous waveforms. This preliminary automation reduces the need for manual correction of each measurement point individually.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system copies the correction made to the reference waveform and applies it automatically to analogous waveforms. This copying mechanism allows one manual correction to propagate to multiple similar waveforms, reducing overall correction time while maintaining precision.

Inventive Principle:
Principle #26Copying

2Measurement precision

If the operator corrects measurement points in large amounts of heartbeat data, then the analysis accuracy is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improveanalysis accuracyVSAvoidoperator burden
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system enables self-service by automatically applying corrections to analogous waveforms based on the reference waveform correction. The system serves itself by propagating the correction pattern across similar waveforms without requiring continuous operator intervention for each individual waveform.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The correction mechanism becomes universal by applying the same correction logic to all analogous waveforms. Once the reference waveform is corrected, the correction pattern serves multiple waveforms simultaneously, making the operation more efficient and less burdensome.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If automatic analysis is used, then the productivity is improved, but the measurement precision deteriorates due to discrepancies with manual analysis

Engineering Contradiction:
Improveanalysis speedVSAvoidmeasurement point accuracy
Core Design Contradiction:

Solution Approach 1:

The system incorporates feedback by using the operator's correction of the reference waveform to automatically adjust and correct analogous waveforms. This feedback loop ensures that manual precision is integrated back into the automatic analysis process, maintaining high accuracy while preserving productivity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system changes the parameter of correction application from individual manual adjustments to automated propagation based on reference correction. This parameter change allows the system to maintain precision by incorporating operator feedback while preserving the speed benefits of automatic analysis.

Inventive Principle:
Principle #35Parameter changes
