Solution Overview

Problem

The existing accordion designs limit the versatility of note layout patterns, restricting the ability of accordionists to play a wide range of songs due to traditional mechanisms and layouts that do not adapt to individual physiology or skill levels, and the transition to electronic accordions has not adequately addressed these limitations.

Innovation Solution

An electronic accordion with a reconfigurable note layout system that includes a functional equation-based button arrangement, allowing for chromatic and scale-based patterns, enabling easy transition between Major and Minor scales, and accommodating various chord types, facilitating the playability of over 90% of public accordion songs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional Stradella bass system layout is used, then historical compatibility and simplicity are maintained, but song repertoire coverage and adaptability to different playing styles are limited

Engineering Contradiction:
Improvesong repertoire coverageVSAvoidnote layout system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic reconfigurability of the button layout system, allowing the accordion to switch between different note patterns (Stradella bass, chromatic, scale-based) during performance. This enables the same physical device to adapt to various song requirements and playing styles, dramatically expanding repertoire coverage without adding multiple fixed systems

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent creates a universal button layout system that can perform multiple functions: traditional Stradella bass for accompaniment, chromatic patterns for melodic playing, and scale-based patterns for folk music. A single button arrangement can serve different musical purposes through electronic reconfiguration, eliminating the need for separate specialized systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If fixed traditional note layout patterns are used, then device simplicity is maintained, but ease of operation for different accordionists and skill levels is reduced

Engineering Contradiction:
Improveplayability for different skill levelsVSAvoidadaptability to individual physiology
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies different note layout patterns to different button zones and rows, optimizing each area for specific functions. For example, certain rows may be configured for root notes while others handle chord variations, and the layout can be customized based on the player's hand size and finger reach, making the instrument easier to operate for different individuals

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system provides pre-configured note layout patterns that are prepared in advance for different playing styles and skill levels. Beginners can select simplified patterns, while advanced players can choose more complex arrangements, eliminating the need for players to manually configure the layout themselves

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If electronic accordion with reconfigurable layout is implemented, then song repertoire coverage and adaptability are improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvenote layout reconfigurabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent replaces complex mechanical reconfiguration mechanisms with electronic control systems. Instead of physically moving buttons or changing layouts mechanically, the system uses electronic signals to reconfigure the button functions and sound output, significantly simplifying the manufacturing process while maintaining full reconfigurability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system uses electronic copying of button functions rather than physical duplication of mechanical components. Each button's function can be digitally copied and reassigned to different notes or chords through software, eliminating the need for multiple physical button sets or complex mechanical switching mechanisms

Inventive Principle:
Principle #26Copying

AI summary

An accordion includes a right hand play side, a left hand play side, a bellow provided between the right hand play side and the left hand play side. A plurality of columns of buttons provide on at least one of the right hand play side and the left hand play side. Each of the plurality of columns may have at least three buttons to which three single pitches are assigned, the three single pitches constituting a triad major chord. Embodiments of the present invention provide a user-friendly system for accordionists that can also cover more than 90% of the accordion songs being public in the world.
