Electronic Music Module for Lightweight Multi-Song Storage Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices, such as jewellery boxes, are heavy, mechanically based, and limited to playing a single piece of music, failing to provide a lightweight, compact, and versatile music-playing solution suitable for children's toys.
Innovation Solution
A device with a lightweight base and closure body, incorporating an electronic music module with a loudspeaker, programmable microcontroller, and sensor systems for automatic music playback, allowing selection and replay of multiple children's songs, along with features like illumination and motor-activated toy figures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical music mechanisms are used in storage devices, then music playback function is achieved, but the device becomes heavy and complex
Solution Approach 1:
The patent replaces traditional mechanical music mechanisms with electronic components including a microcontroller unit, memory storage, and electronic amplifier with speaker. This substitution eliminates heavy mechanical parts while achieving music playback functionality through electronic systems, directly resolving the contradiction between music playback capability and device weight.
Solution Approach 2:
The storage device is designed to serve multiple functions: it acts as both a storage container for everyday objects and a music player. The electronic music module is integrated into the base body, allowing the same device to fulfill both storage and entertainment purposes, particularly suitable for children's toys as mentioned in the patent.
2Device complexity
If single-piece music mechanisms are used, then simple device structure is maintained, but music variety is limited
Solution Approach 1:
The patent incorporates a memory storage unit that pre-stores multiple music pieces before use. The microcontroller can select and play different stored music pieces, providing music variety without requiring complex real-time generation mechanisms. This preliminary storage approach allows diverse music output while maintaining relatively simple device structure.
Solution Approach 2:
The electronic system allows for easy modification of music content by changing the stored data in memory. Different music pieces can be programmed into the system, and the microcontroller can be configured to play different sequences or selections. This parameter change capability provides music variety without increasing structural complexity.
3Weight of moving object
If electronic music modules are integrated into storage devices, then music variety and lightweight design are achieved, but manufacturing complexity increases
Solution Approach 1:
The music module is designed as a separate, self-contained unit with its own housing that can be produced independently. This segmentation allows the electronic components (microcontroller, memory, amplifier, speaker) to be assembled and tested as a module before integration into the final storage device, simplifying the manufacturing process despite the electronic complexity.
Solution Approach 2:
The patent uses a modular music module as an intermediary component between the electronic control system and the final product. This module serves as a pre-assembled unit that simplifies integration into the storage device, making manufacturing easier despite the sophisticated electronic functionality required for lightweight design.
