Storytelling Projector for Synchronized Light and Recorded Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices lack the ability to project light patterns synchronized with audio playback, particularly in response to user-selected characters and environments, and do not allow users to record their own stories with synchronized light projections.
Innovation Solution
An electronic device that projects colored light patterns synchronized with audio playback, allowing users to select characters and environments for pre-recorded stories, and enables recording and playback of user-generated stories with synchronized light patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light projection and audio playback functions are combined in a single device, then the device provides a more immersive storytelling experience, but the device complexity increases
Solution Approach 1:
The patent combines light projection and audio playback functions into a single integrated device. The housing contains both light-emitting members (LEDs) and audio components (speaker, microphone), allowing simultaneous projection of synchronized light patterns and playback of recorded stories with sound effects and music.
Solution Approach 2:
The device performs multiple functions: it plays back pre-recorded stories with synchronized light projections, records user-customized stories with audio and light patterns, and provides both visual and auditory stimulation to create an immersive storytelling experience for children.
2Adaptability or versatility
If light patterns are synchronized with audio playback at specific story points, then the immersive experience is enhanced, but the control system complexity increases
Solution Approach 1:
The device uses pre-recorded audio files that contain stories with embedded timing information. The microprocessor is programmed with predetermined timing sequences that trigger light pattern changes at specific points in the story playback, eliminating the need for real-time audio analysis and simplifying the synchronization control.
Solution Approach 2:
The device employs timing feedback mechanisms where the microprocessor monitors playback progress and triggers light pattern changes based on predetermined time markers embedded in the audio files, ensuring synchronized light and sound effects throughout the story.
3Adaptability or versatility
If users can record and play back their own stories with synchronized light patterns, then the device versatility increases, but the device complexity increases
Solution Approach 1:
The device enables users to record their own stories by capturing audio through a built-in microphone and storing it in memory. Users can then play back their recorded stories with synchronized light patterns, allowing the device to serve itself in creating customized storytelling content without requiring external recording equipment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Creates an immersive experience by synchronizing light, color, and sound with story actions, providing a unique listening experience for children.
Implementation Method 1
a plurality of light emitting members that emit light from within the housing
Implementation Method 2
projector domes positioned within the clear top portion... the light is projected from within the housing by the plurality of light emitting members and from each projector dome

AI summary
A children's toy, and electronic device, plays audio files and projects differently-colored light patterns onto a surface in a room in which the device is placed. The light patterns are projected in synchronization with the playback of such audio files. The device allows users to select from different nature sounds, different melodies, or multiple pre-recorded children's stories. The device also enables users to record their own stories for each of several environments, and playback their custom stories together with projections of light in each environment.
