Solution Overview

Problem

Many individuals suffer from insomnia and other sleep-related disorders, and existing methods lack personalized recommendations for activities that effectively increase sleepiness and manage insomnia symptoms.

Innovation Solution

A system and method that receive physiological data from users, determine their initial sleepiness levels, prompt them to perform specific activities, and assess the effectiveness of these activities by calculating activity scores based on subsequent sleepiness levels, allowing for personalized recommendations and adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a system provides personalized sleepiness management recommendations, then the effectiveness of sleepiness increase is improved, but the device complexity increases

Engineering Contradiction:
Improveeffectiveness of sleepiness increaseVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system continuously monitors physiological data (heart rate, temperature, activity levels) and uses this feedback to dynamically adjust sleepiness recommendations. The system tracks user responses to recommended activities and refines future recommendations based on observed effectiveness, creating a closed-loop control system that improves reliability while managing complexity through iterative optimization.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system manages complexity by focusing on key physiological parameters (heart rate, body temperature, activity level) that correlate with sleepiness states. By monitoring and analyzing changes in these specific parameters rather than all possible physiological variables, the system achieves effective personalized recommendations without requiring excessively complex measurement and processing systems.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If the system collects and analyzes detailed physiological data, then the precision of sleepiness level determination is improved, but the loss of information increases due to data processing requirements

Engineering Contradiction:
Improvesleepiness level determination precisionVSAvoiddata processing overhead
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The system extracts only the most relevant features from collected physiological data for sleepiness determination. Instead of processing all raw physiological signals, the system identifies and extracts key indicators (such as heart rate variability patterns, temperature trends, and activity level changes) that most strongly correlate with sleepiness states, reducing data processing requirements while maintaining determination precision.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary processing and filtering of physiological data at the point of collection, preparing data in advance for analysis. By pre-processing signals to remove noise and organize data into meaningful patterns before main analysis, the system reduces the computational burden during sleepiness determination while preserving the precision needed for accurate assessment.

Inventive Principle:
Principle #10Preliminary action

AI summary

A system includes a memory device storing machine-readable instructions and a control system including one or more processors configured to execute the machine-readable instructions to receive initial physiological data associated with a user, determine, based at least in part on initial physiological data, an initial sleepiness level for the user, prompt the user, via an electronic device, to perform a first activity, receive subsequent physiological data associated with the user, determine, based at least in part on the subsequent physiological data, a subsequent sleepiness level for the user, and determine a first activity score based at least in part on the initial sleepiness level and the subsequent sleepiness level, the first activity score being indicative of an effectiveness of the first activity in modifying the sleepiness of the user.
