Plush Toy Audio Loop for Uninterrupted Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current recordable plush toys for babies require external connections and limitations in recording and playback duration, such as silence between loops or restricted playback times, which restrict their functionality as effective sleeping accessories.
Innovation Solution
A digital recording device integrated into plush toys, featuring control circuits, a microphone, speaker, battery, and memory, allowing users to record audio for a short period and play it back repeatedly without silence, with adjustable recording and playback times, and the ability to operate independently without external cables or internet connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the recording duration is limited to a short period (e.g., 20 seconds), then the device can operate with limited memory and battery, but the playback contains silence periods that reduce its effectiveness as a sleeping accessory
Solution Approach 1:
The system maintains continuous useful action by immediately replaying the recorded audio as soon as the recording stops, eliminating any silence periods. The playback loop continuously cycles through the recorded audio without interruption, ensuring the soothing sound persists throughout the baby's sleep period without gaps that would reduce its effectiveness.
2Device complexity
If the device allows looping playback of a fixed duration (e.g., 20 seconds), then the playback structure is simple, but recordings shorter than the loop duration are padded with silence
Solution Approach 1:
The system applies dynamics by making the playback loop duration adaptive rather than fixed. The loop duration dynamically adjusts to match the actual recording length, whether the recording is 5 seconds or 20 seconds. This dynamic adjustment eliminates the need for silence padding while maintaining a simple playback structure, as the system automatically configures the loop to fit the recorded content perfectly.
3Adaptability or versatility
If the device requires USB cable and Internet connection for recording, then external resources can be utilized, but the device complexity increases and portability is reduced
Solution Approach 1:
The system implements self-service by incorporating all necessary recording and playback functionality directly into the device. The built-in microphone captures audio, the integrated memory stores the recording, and the onboard speaker plays it back. This self-contained architecture eliminates the need for external USB cables or Internet connections, reducing device complexity while maintaining full recording capability for creating soothing audio content.
4Quantity of substance
If the device allows only one playback of the recording (up to 20 seconds), then the memory requirement is minimal, but the playback duration is insufficient for overnight use
Solution Approach 1:
The system applies periodic action by implementing a continuous loop that repeatedly plays back the recorded audio. Instead of a single playback, the recording cycles continuously through multiple iterations, creating an extended effective playback duration. This periodic repetition allows the device to provide soothing audio throughout the entire night using minimal memory capacity, as the same short recording fulfills the extended duration requirement through repeated cycles.
Data Source
AI summary
A method and apparatus for providing long playback of short recordings are disclosed. An example method includes recording audio for a time period that is less than a maximum recording time, receiving an indication that the audio is to be played back, playing the audio back for a duration corresponding to the time period, determining the audio is to be repeated, and responsive to determining that the audio is to be repeated, at the end of the time period duration, playing the audio back multiple times for a preset time or preset number of repetitions.
