Keyboard Instrument with Light-Emitting Keys for Section Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic keyboards lack the ability to easily designate and play specific sections of a track, making it difficult for users to isolate and practice impressive or well-known parts of a song.
Innovation Solution
An electronic keyboard instrument with light-emitting keys, where specific keys are assigned to different sections of a track based on luminance levels, allowing users to visually distinguish and play desired sections by depressing corresponding keys, which are associated with unique section data items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic keyboards have light emitting keys with various lesson functions, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The keyboard is divided into multiple keys, each associated with specific section data of a musical piece. Each key can be independently lit to indicate different sections (e.g., verse, chorus, bridge), allowing users to select and practice specific portions of a song without complicating the overall device architecture.
Solution Approach 2:
Different keys have different luminance levels or lighting patterns to indicate different sections of the musical piece. This local differentiation allows users to quickly identify which key corresponds to which section, improving ease of operation without requiring a complex display system.
2Ease of operation
If users can designate specific sections of a track, then the ease of operation is improved, but additional display units or interfaces are required
Solution Approach 1:
The section selection functionality is merged into the existing keyboard structure. The keys serve dual purposes: playing musical notes and selecting sections of a track. This eliminates the need for separate display units or additional interfaces, as the keyboard itself becomes the selection mechanism.
Solution Approach 2:
The keyboard keys are designed to perform multiple functions: they can be used for traditional musical note input, section selection, and visual indication of different musical sections. This multi-functionality allows section designation without adding separate control mechanisms, maintaining device simplicity.
3Productivity
If keys are associated with section data for different parts of a piece of music, then the productivity of music practice is improved, but the device complexity increases
Solution Approach 1:
Section data for different parts of a musical piece (verse, chorus, bridge, etc.) is pre-associated with specific keys before the user begins practicing. When a user presses a key, the corresponding section is immediately ready to play, eliminating the need for manual section selection or complex setup, thus improving practice productivity.
Solution Approach 2:
The keyboard system automatically manages section data assignment and playback based on key presses. The processor handles the complexity of managing multiple section data items, timing information, and playback control, while the user simply needs to press the desired key, making the system self-sufficient and reducing perceived complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to quickly and easily select and play specific parts of a track, such as motifs, without the need for additional display units, facilitating practice and music learning by visually differentiating keys based on luminance levels.

AI summary
A keyboard instrument includes a processor and a keyboard including first, second and third keys. The first key is associated with first section data corresponding to a first section among a plurality of sections in a piece of music, includes at least two notes and corresponds to a first period of the piece of music. The second key is associated with second section data corresponding to a second section following the first section, includes at least two notes and corresponds to a second period of the piece of music. The third key is not associated with any section data. The processor displays an identifier such that the first and second keys are distinguishable from the third key, outputs the first section data as a musical sound when the first key is operated; and outputs the second section data as a musical sound when the second key is operated.
