Solution Overview

Problem

Conventional sleep induction systems provide stimuli based on experimentally determined physiological signal ratios without considering the user's individual periodicity, failing to synchronize stimuli with the user's actual physiological signals.

Innovation Solution

An electronic device and method that identify the periodicity of user's physiological signals, such as respiration, by detecting user activities independent of the physiological signals and providing auditory feedback synchronized with these periodicities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional systems provide stimuli based on experimentally determined physiological signal ratios, then sleep induction content can be provided, but the stimuli are not synchronized with the user's actual physiological signals

Engineering Contradiction:

Improveadaptability to user's individual periodicityVSAvoidsynchronization accuracy with physiological signals

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system detects user activities (such as respiration movements) and uses this feedback to identify the user's actual physiological periodicity, then adjusts the stimuli timing to synchronize with the detected periodicity, resolving the contradiction between providing general sleep content and adapting to individual user rhythms

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system enables users to self-regulate their physiological signals by providing stimuli that are synchronized with their own detected periodicity, allowing users to autonomously achieve desired sleep states without external control, thus improving both adaptability and synchronization accuracy

Inventive Principle:

Principle #25Self-service

2Ease of operation

If stimuli are provided without identifying user periodicity, then system complexity is reduced, but user engagement decreases

Engineering Contradiction:

Improveuser engagementVSAvoidperiodicity detection mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system uses user activities (such as breathing movements detected by sensors) as an intermediary to indirectly measure physiological periodicity without requiring direct physiological signal measurement, thereby improving user engagement while avoiding complex detection mechanisms

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces complex physiological signal detection with simpler activity-based detection methods, such as using motion sensors to detect breathing patterns instead of requiring direct respiratory signal measurement, thus maintaining ease of operation while improving user engagement

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

According to one embodiment, a method for providing a sound for sleep induction may include an operation of providing a first sound corresponding to a first user activity based on detecting the first user activity associated with user cognition regarding a period for inhalation of the user's breathing. The first user activity may be a user activity independent of the inhalation rather than a user activity caused by the inhalation of the breathing, and a start time point of providing the first sound may be substantially synchronized with a detection time point of the first user activity. The method may include an operation of providing a second sound corresponding to a second user activity based on detecting the second user activity associated with user cognition regarding a period for exhalation of the user's breathing. The second user activity may be a user activity independent of the exhalation rather than a user activity caused by the exhalation of the breathing, and a start time point of providing the second sound may be substantially synchronized with a detection time point of the second user activity.
