Children's Soothing Output Synchronization for Vibration and Lights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional children's products lack the ability to synchronize sound and non-sound outputs, such as vibration and lights, with music, leading to potential overstimulation or irritation of children, as they only offer constant activation options without synchronization.
Innovation Solution
A system that includes a management computing entity and user computing device to synchronize sound and non-sound outputs, using non-sound event markers in media files to control vibration motors and lighting systems in conjunction with music playback, allowing for customizable and timed activation of these features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vibration and lights are activated in conventional children's products, then the child may be soothed, but constant vibration and light operation may overstimulate or irritate the child
Solution Approach 1:
The system activates vibration and lights periodically synchronized with music playback rather than continuously. The controller receives music signals, detects beat patterns, and triggers vibration motors and lights only during specific musical segments, creating periodic on-off cycles that prevent constant stimulation while maintaining soothing effectiveness during active periods.
Solution Approach 2:
The system dynamically adjusts the activation state of vibration and lights based on real-time music signal analysis. The controller continuously monitors the music playback and dynamically switches between active and inactive states for vibration and lights, adapting their operation to the musical content rather than maintaining a fixed state.
2Reliability
If vibration and lights are synchronized to music at predetermined times, then an improved soothing aspect is provided, but the device complexity increases
Solution Approach 1:
The system combines multiple functions into a single integrated controller that handles music signal reception, beat detection, timing determination, and coordinated control of both vibration motors and lights. This merging of functions into one control unit reduces overall system complexity compared to having separate control systems for each component.
Solution Approach 2:
The controller acts as an intermediary that receives music signals from the audio output, processes them to determine timing information, and then uses this information to coordinate the activation of vibration and lights. This intermediary processing layer simplifies the synchronization task by centralizing the timing decision-making logic.

AI summary
A children's soothing device, such as a motorized swing, a motorized glider, a motorized rocker, a motorized bouncer, a playard, a crib, a car seat, a stroller, an infant carrier, or a bassinet, can include one or more speakers, one or more vibrating motors or solenoids, and one or more light attractions or lights for soothing a child. The children's soothing device can include a control system for storing and reading sound and other data files to output music or other sounds through the speakers and to activate and deactivate the vibrating motors in a synchronized pattern with the sound or music. The children's soother device can also evaluate the sound and other data files to synchronize the activation, deactivation, and/or change of state of the light attraction or lights with the sound/music and the vibrating motors.
