Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for breathing training fail to effectively detect and provide feedback on synchronization between the chest and abdomen movements during breathing, making it difficult for individuals to recognize and correct improper breathing techniques.
Innovation Solution
An information processing apparatus and method that calculates phase differences between chest and abdominal waveforms during expiratory and inspiratory phases, allowing for real-time feedback on synchronization and improving breathing technique accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only peak detection of chest and abdominal waveforms is used to determine expiratory and inspiratory phases, then the breathing phase switching time can be detected, but synchronization between chest and abdominal waveforms in each phase cannot be confirmed
Solution Approach 1:
The patent segments the breathing cycle into distinct expiratory and inspiratory phases using peak detection, then separately analyzes synchronization within each phase. This segmentation allows detailed examination of chest-abdomen coordination during specific breathing phases, preventing loss of synchronization information that would occur with holistic analysis alone.
Solution Approach 2:
The patent implements feedback by comparing chest and abdominal waveform phases within each breathing phase and providing information about synchronization status. This feedback mechanism enables confirmation of whether chest and abdomen movements are coordinated properly during expiration and inspiration, addressing the information loss problem.
2Loss of information
If detailed phase-by-phase synchronization analysis is performed, then synchronization timing can be identified, but the complexity of the analysis system increases
Solution Approach 1:
By dividing the breathing cycle into discrete expiratory and inspiratory phases based on peak detection, the system simplifies the analysis complexity while enabling detailed synchronization examination. Each phase can be analyzed independently with straightforward comparison of chest and abdominal waveform timing, avoiding the need for complex continuous analysis.
Solution Approach 2:
The patent applies different analysis approaches to different breathing phases - using peak detection for phase identification and phase difference calculation specific to each phase. This localized approach allows detailed synchronization information to be obtained where needed while maintaining overall system simplicity through phase-specific rather than universally complex analysis.
Data Source
AI summary
An information processing apparatus inputs expiratory phase data being data of expiratory phase and inspiratory phase data being data of inspiratory phase, for each of abdominal waveform data indicating a breathing waveform of an abdomen of a subject performing breathing training and chest waveform data indicating a breathing waveform of a chest of the subject. The information processing apparatus calculates a phase difference between the abdominal waveform data and the chest waveform data in each of the expiratory phase and the inspiratory phase.
