Solution Overview

Problem

Current methods for assessing infant feeding performance are subjective and lack objective, quantitative standards, particularly for pre-term infants, leading to inadequate screening and increased hospital readmission rates and medical service usage due to undetected feeding issues.

Innovation Solution

A method and system for evaluating infant feeding performance by processing digitized data from feeding sessions to calculate a relative score compared to population-based metrics, providing a user-recognizable output that assesses feeding performance and risk for adverse outcomes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If subjective assessment methods are used for infant feeding evaluation, then the assessment process is simple and quick, but the measurement precision and objectivity are insufficient

Engineering Contradiction:
Improvefeeding performance assessment accuracyVSAvoidassessment system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces subjective human observation and manual assessment with an automated electronic system that uses sensors to detect feeding parameters (sucking pressure, flow rate, swallowing patterns) and a computer algorithm to analyze the data. This substitution of mechanical/electronic systems for human judgment achieves objective, quantitative measurement while maintaining operational simplicity through automated analysis.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The assessment system performs self-evaluation by automatically collecting data during feeding, processing the signals through embedded algorithms, and generating feeding scores without requiring external expert intervention. The system serves itself by integrating data collection, analysis, and interpretation into a single automated workflow that produces objective results independently.

Inventive Principle:
Principle #25Self-service

2Reliability

If comprehensive feeding assessment is performed for all infants, then the detection of feeding issues is improved, but the time and resources required increase

Engineering Contradiction:
Improvefeeding issue detection reliabilityVSAvoidassessment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements a tiered assessment approach where the automated system continuously monitors feeding parameters and selectively triggers detailed evaluation only when abnormal patterns are detected. This partial action principle allows comprehensive monitoring of all infants while focusing detailed assessment resources only on those showing signs of feeding problems, thereby improving detection reliability without proportionally increasing time investment for all patients.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system rapidly processes feeding data through automated algorithms that can quickly analyze seconds of feeding behavior to generate assessment scores. This rushing through the assessment process via automated computation enables comprehensive evaluation of multiple infants in the time it would traditionally take to assess one infant manually, significantly reducing time loss while maintaining high detection reliability.

Inventive Principle:
Principle #21Skipping (Rushing through)

3Measurement precision

If specialized personnel perform feeding assessment, then the measurement precision is improved, but the ease of operation and accessibility are reduced

Engineering Contradiction:
Improvefeeding assessment accuracyVSAvoidassessment accessibility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The assessment system is designed to be self-operating with automated data collection, processing, and interpretation that requires minimal human intervention. Any trained personnel can initiate the assessment by placing the sensor on the infant, and the system automatically performs the complex analysis that would otherwise require specialized expertise. This self-service capability democratizes access to high-precision assessment while maintaining measurement accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces an automated computer algorithm as an intermediary between the raw feeding data and the final assessment interpretation. This intermediary processes the complex sensor data and translates it into meaningful feeding scores and recommendations, bridging the gap between simple data collection and expert-level interpretation. This allows non-specialists to achieve expert-level assessment accuracy through the mediating computational system.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A computational method for generating a feeding score for an individual infant based upon a comparison of feeding factor measurements obtained from the individual infant, values associated with the feeding factor measurements, and feeding parameter metrics from a population of infants having a similar gestational age as the individual infant.
