Electronic Music Content Data Usage Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic instruments face challenges in providing users with personalized musical content data due to high storage and copyright costs, as well as cumbersome download processes, which burden users with complex setup and internet connectivity requirements.
Innovation Solution
A content data usage apparatus that employs a protected storage unit, content selection unit, and content use control unit, utilizing an IC chip for electronic money settlement, allowing users to select and access desired content data without needing internet connection or complex setup, by separating settlement and content usage systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If many content data are preset in the electronic instrument to satisfy all users, then the user selection range is improved, but the storage capacity requirement and copyright cost increase
Solution Approach 1:
The content data is segmented into two parts: a small set of freely usable content data preset in the electronic instrument, and additional content data stored on an external recording medium. This segmentation allows users to access a large selection range without requiring the electronic instrument to have large storage capacity, thus resolving the contradiction between user selection range and storage capacity requirement.
2Adaptability or versatility
If content data are downloaded from Web server to electronic instrument, then the user can obtain desired content data, but the operation complexity and time consumption increase
Solution Approach 1:
The desired content data is preliminarily installed on an external recording medium before use. When the user needs content data, they simply need to insert the external recording medium into the electronic instrument and perform a simple selection operation, rather than performing complex download operations from a Web server. This preliminary action significantly reduces operation complexity and time consumption.
3Adaptability or versatility
If content data are installed from external recording medium and purchased from Web server, then the user can release use restriction, but the operation complexity and time consumption increase
Solution Approach 1:
The installation and purchase operations are merged into a single integrated process. The external recording medium contains both the content data and the necessary purchase information, allowing users to complete both installation and purchase by simply inserting the medium and following a unified操作流程, thereby reducing operation complexity and time consumption compared to separate installation and purchase processes.

AI summary
An electronic musical instrument has a protected storage unit in which a plurality of music content data are preset and stored in an unusable state where a user cannot freely use. A content selection unit is operated by the user to select a desired one of the music content data from the plurality of the music content data. A content use control unit causes an external settlement apparatus to make settlement for purchasing the desired music content data to thereby enable use of the desired music content data selected by the content selection unit, and brings the desired music content data into a usable state when a completion notification indicating that the settlement is completed is received from the external settlement apparatus. A play unit is operable to use the desired music content data for generating or reproducing music sounds according to the desired music content data.
