Solution Overview

Problem

Existing sleep-inducing technologies primarily focus on noise masking to reduce interference, failing to actively induce sleep.

Innovation Solution

A sleep induction device that determines a characteristic frequency based on a user's breathing frequency and outputs a breathing-tuned sound to synchronize with and gradually slow the user's breathing, combining this with noise masking sound to enhance sleep induction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If noise masking sound is used to reduce ambient noise, then the interference with user's sleep is reduced, but the technology cannot actively induce the user's sleep

Engineering Contradiction:
Improveambient noise interferenceVSAvoidsleep induction effectiveness
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent changes the parameter of sound frequency by analyzing the user's breathing frequency and generating a breathing-tuned sound with a characteristic frequency that is a multiple of the breathing frequency. This active frequency manipulation goes beyond passive noise masking to actively induce sleep by synchronizing with and gradually slowing the user's breathing pattern.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If breathing-tuned sound with characteristic frequency is output to induce sleep, then the user's breathing is actively induced to become slower, but the device complexity increases due to breathing frequency analysis and dynamic frequency adjustment

Engineering Contradiction:
Improvesleep induction effectivenessVSAvoidbreathing frequency analysis and frequency adjustment mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically analyzing the user's breathing frequency and autonomously adjusting the characteristic frequency of the output sound. The processor continuously monitors breathing patterns and dynamically modifies the breathing-tuned sound parameters without requiring manual intervention, thereby managing the complexity internally while maintaining simplicity for the user.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements feedback by continuously monitoring the user's breathing frequency through the sensor and using this information to dynamically adjust the characteristic frequency of the breathing-tuned sound. This closed-loop feedback mechanism ensures the sound remains synchronized with the user's breathing pattern, optimizing sleep induction while systematically managing the complexity through automated control.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the characteristic frequency is reduced in a stepwise manner to prevent large difference from breathing frequency, then the user is naturally induced to breathe according to the sound, but the time required for sleep induction increases

Engineering Contradiction:
Improvenatural breathing inductionVSAvoidsleep induction time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent applies dynamics by making the characteristic frequency adjustable and adaptive rather than fixed. The system dynamically modifies the breathing-tuned sound's characteristic frequency based on real-time breathing frequency analysis, allowing flexible adjustment of the frequency difference. This dynamic approach balances the need for gradual adaptation with the goal of reducing overall induction time.

Inventive Principle:
Principle #15Dynamics
