Electronic Music Box Random Playback Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic music boxes lack variability and can become monotonous, leading to repetitive and unpleasant listening experiences, especially when used for soothing purposes like cradling a baby.
Innovation Solution
An electronic music box system that includes a music data memory, a random table memory, and a controller to automatically select and weight music pieces for playback, ensuring a diverse and engaging playlist by introducing 1/f fluctuation in tempo and amplitude, and allowing for new music pieces to be incorporated from an external server, while maintaining a consistent tempo for soothing environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a limited number of music pieces are stored in the music box, then the device complexity is reduced, but the listening experience becomes monotonous and repetitive
Solution Approach 1:
The patent applies dynamics by making the music playback order variable rather than fixed. The controller randomly determines the playback sequence of music pieces from the limited storage, transforming a static playback system into a dynamic one that provides variety without requiring additional music storage capacity.
Solution Approach 2:
The patent combines multiple music pieces into a composite playlist that is dynamically assembled through random selection. This creates a composite music experience that varies with each playback session, effectively increasing versatility while maintaining a simple device structure with limited storage.
2Device complexity
If music pieces are played in a fixed pattern, then the device complexity is reduced, but the listening experience becomes predictable and boring
Solution Approach 1:
The control system transitions from a fixed, deterministic playback pattern to a dynamic random selection mechanism. This allows the system to maintain simplicity in hardware while achieving variability in output, preventing the listening experience from becoming predictable or boring.
3Adaptability or versatility
If the tempo varies between music pieces, then the adaptability to different moods is improved, but the soothing effect for cradling a baby is reduced
Solution Approach 1:
The patent applies local quality by maintaining a consistent tempo specifically for baby cradling scenarios while allowing tempo variation in other contexts. The system can select music pieces with appropriate tempos suited for soothing purposes, creating a localized optimization for the specific use case of cradling a baby.
Data Source
AI summary
Music data memory includes pieces of music within a group and other pieces of music outside the group. The next piece to be played is automatically determined by random table among pieces within the group. Favorite or newest piece is weighted to be more frequently played in the group. Piece in music data memory is automatically included into the group by random table. Newly downloaded piece into music data memory is included into the group by priority. Most frequently played piece is excluded from the group in place of newly included piece. Favorite or newest piece may be an exception of exclusion. Next piece is capable of being played in tempo similar to that of preceding piece by means of tempo-adjusted or piece replacement or repetition of the same piece for the purpose of continued baby cradling in synchronism with the same tempo of succeeding pieces.
