Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing infants, particularly those of average prematurity, are inadequate as they rely on observational techniques that are subjective, unreliable, and require specialized training, leading to late identification of developmental disorders and low predictive validity.
Innovation Solution
A method utilizing a touch screen device to display targets and detect contact made by the baby, calculating success parameters based on contact data, and recording them for objective and reliable assessment, which can be executed by various professionals without extensive training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If observational tests based on practitioner judgement are used, then the test can be administered without specialized equipment, but the measurement precision and reliability are low due to subjectivity and observer experience variability
Solution Approach 1:
The patent replaces the mechanical/subjective observational system with an electronic touch screen detection system. The touch screen objectively detects and records infant contacts, replacing practitioner judgement with automated digital measurement, thereby eliminating observer variability while maintaining administrative simplicity.
Solution Approach 2:
The patent creates a digital copy of the infant's motor responses through touch screen contact detection. Instead of manually observing and recording behavior, the system digitally captures contact location, duration, and frequency, enabling precise measurement without requiring complex observational equipment.
2Reliability
If classic developmental scales based on general observations are used, then the test can be administered to infants, but the predictive validity is low due to general test items that cannot ascertain precise evaluation of elementary cognitive capacities
Solution Approach 1:
The patent applies local quality by focusing measurement on specific, localized touch screen contact points rather than general behavioral observations. Each contact location, duration, and pattern provides specific data about elementary cognitive capacities, enabling precise evaluation of particular skills rather than general developmental assessment.
Solution Approach 2:
The patent changes the measurement parameters from general behavioral categories to specific quantifiable metrics including contact location coordinates, contact duration in milliseconds, contact frequency, and response time. These parameter changes enable precise measurement of cognitive capacities while maintaining ease of administration through automated tracking.
3Measurement precision
If tests rely on practitioner observation and judgement, then the test can be administered without specialized equipment, but the test-retest fidelity is very low with considerable variability of scores attributed to the same infant at the same age
Solution Approach 1:
The patent replaces the mechanical/subjective observational system with an electronic touch screen detection system. The touch screen objectively detects and records infant contacts, replacing practitioner judgement with automated digital measurement, thereby eliminating observer variability while maintaining administrative simplicity.
Solution Approach 2:
The patent implements feedback by automatically recording and storing contact data with precise timing and location information. This creates an objective record that can be compared across test sessions, enabling high test-retest fidelity through consistent digital measurement rather than variable human observation.
4Measurement precision
If the Fagan test relying on infant reaction to novelty is used, then cognitive evaluation is improved compared to other tests, but the predictive validity for estimating developmental delays or predicting IQ is highly inadequate
Solution Approach 1:
The patent applies local quality by focusing measurement on specific, localized touch screen contact points rather than general behavioral observations. Each contact location, duration, and pattern provides specific data about elementary cognitive capacities, enabling precise evaluation of particular skills rather than general developmental assessment.
Solution Approach 2:
The patent changes the measurement parameters from general behavioral categories to specific quantifiable metrics including contact location coordinates, contact duration in milliseconds, contact frequency, and response time. These parameter changes enable precise measurement of cognitive capacities while maintaining ease of administration through automated tracking.
