Sleep Training Device with Dynamic Stimuli Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many young children have difficulty falling or staying asleep due to reliance on external sleep associations, making it challenging for caregivers to implement effective sleep training methods that promote independent sleep and self-soothing.
Innovation Solution
A device comprising sensors and output devices, connected to a processor, that detects the child's state and generates responses to help them self-soothe, gradually reducing the intensity and duration of stimuli over time to break sleep associations and promote continuous sleep.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a device provides continuous external stimuli to help children fall asleep, then sleep onset is facilitated, but sleep associations are reinforced and independence is reduced
Solution Approach 1:
The device dynamically adjusts the level of external stimuli over time, transitioning from active intervention to passive support. The system adapts its response based on the child's sleep state and duration, gradually reducing assistance to promote independence while maintaining ease of sleep onset during the adjustment period.
Solution Approach 2:
The device changes key parameters of external stimuli (intensity, duration, type) based on detected sleep states and elapsed time. By modifying these parameters dynamically, the system facilitates initial sleep onset with higher intensity stimuli then gradually reduces them to extinguish sleep associations and promote self-soothing independence.
2Reliability
If caregivers manually intervene to help children sleep, then sleep training can be implemented, but time and effort requirements increase significantly
Solution Approach 1:
The device enables self-service sleep training by automatically detecting the child's sleep state and providing appropriate stimuli without requiring continuous caregiver intervention. The system performs the sleep training function autonomously, maintaining reliability while eliminating the significant time and effort burden on caregivers.
Solution Approach 2:
The device implements closed-loop feedback by continuously monitoring sleep state parameters and adjusting stimuli accordingly. This automated feedback mechanism ensures consistent sleep training effectiveness without requiring caregivers to manually assess and respond to the child's needs, dramatically reducing time investment while maintaining reliability.
3Duration of action of stationary object
If external aids are used to maintain sleep, then sleep continuity is improved, but the ability to self-soothe is prevented
Solution Approach 1:
The device employs periodic assessment of sleep continuity rather than continuous external support. By checking sleep state at intervals and providing minimal necessary stimuli only when wakefulness is detected, the system maintains sleep continuity while creating opportunities for the child to develop self-soothing abilities during brief awakenings.
Solution Approach 2:
The device extracts and removes external aids gradually as sleep continuity is established. By systematically reducing and eventually eliminating external stimuli once the child demonstrates sustained sleep periods, the system maintains sleep continuity during the training period while ultimately developing self-soothing independence.

AI summary
A method for promoting continuous sleep of a subject by eliminating and/or preventing sleep associations includes: (a) providing an apparatus including at least one sensor and at least one output device; (b) monitoring a state of the subject using the apparatus; (c) determining the subject is in an awake state using the at least one sensor; (d) in response to determining the subject is in the awake state, initiating and maintaining an output using the at least one output device; (e) determining the subject is in a sleep state using the at least one sensor; (f) halting the output in response to determining that the subject is in the sleep state such that the apparatus does not produce any output; (g) repeating at least step (b) during a sleep session. The method further includes modifying an intensity of the output over time until the intensity reaches zero.
