Optical Code Music Learning System for Beginners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music learning methods and materials are not suitable for beginners who cannot play musical instruments and are costly due to the use of electronic circuits and loudspeakers in cards, making them unsuitable for general home use, especially for children and infants.
Innovation Solution
A musical instrument system comprising a sound element medium with pitch and tone information areas printed on cards, readable by a pen-type reader converter that generates musical sound information, allowing users to play songs without needing to play an instrument, and reducing manufacturing costs by using optically readable dot patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic circuits with computer chips and loudspeakers are built in cards for music learning, then the music learning material can play sounds and teach pitch and tone, but the manufacturing cost increases and becomes expensive for general home use
Solution Approach 1:
The patent uses optical codes (dot patterns) printed on cards that can be read by a scanner or camera, replacing the need for expensive electronic circuits and loudspeakers in each card. The sound information is copied onto the card as visual patterns rather than embedded electronics, dramatically reducing manufacturing cost while maintaining functionality.
Solution Approach 2:
The patent replaces the mechanical/electronic system of built-in circuits and loudspeakers with an optical information system. Instead of embedding electronic components, the music information is encoded as optical patterns that can be read remotely, substituting a complex electronic-mechanical system with a simpler optical-information system.
2Reliability
If musical instruments are used for learning, then pitch and tone sense can be developed through playing, but beginners who cannot play instruments well cannot effectively use traditional instruments for learning
Solution Approach 1:
The patent introduces an intermediary system between the learner and traditional instruments. The optical code cards serve as intermediaries that contain music information, and a scanning device acts as another intermediary to translate these codes into sound. This intermediary chain allows beginners to learn music without needing to physically play instruments, as the system handles the complex tasks of information storage and sound generation.
3Adaptability or versatility
If traditional musical instruments are used for learning, then music can be played, but the complexity of playing techniques creates a barrier for beginners
Solution Approach 1:
The patent segments the music learning process into separate functional components: optical code cards for information storage, scanning devices for information retrieval, and sound generation systems for audio output. This segmentation allows each component to be simple and specialized, avoiding the complexity of traditional instruments that require mastery of multiple playing techniques simultaneously.
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
The system enables users to easily play and compose music, developing their sense of pitch and tone, and is cost-effective, making it accessible to learners who cannot play traditional instruments, including children and infants.
Implementation Method 1
the sound element information is printed on the display in a superimposed manner to be optically readable by the reader
Data Source
AI summary
A musical instrument system includes a sound element medium including a plurality of sound-element information areas each having sound element information on a sound element, a reader configured to read the sound element information, a generator configured to generate musical sound information based on the read sound element information, and an audio unit configured to produce a sound based on the generated musical sound information, each of the sound-element information areas having a display corresponding to the sound element information, and the sound element information relating to both or one of pitch and tone.
