Solution Overview

Problem

The standard Richter Tuning of the harmonica is non-linear and lacks essential notes, making it difficult to play contemporary music, particularly as it cannot efficiently produce common chords and scales like A minor, D minor, and E minor pentatonic, which are crucial for modern music.

Innovation Solution

A new note arrangement where pentatonic scales are configured linearly across both blow and draw reeds, allowing for more notes, trills, and glissandos, enabling easier playability and access to various scales, including A minor, D minor, and E minor pentatonic scales by positioning the tonic on any hole.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If Richter Tuning is used, then the harmonica can play traditional Bohemian marching band music, but it lacks essential notes for contemporary music and is difficult to play

Engineering Contradiction:
Improveability to play contemporary music scalesVSAvoiddifficulty to play
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent changes the fundamental parameter of note arrangement from Richter Tuning to Pentatonic I-IV-V tuning. This reconfiguration positions the I, IV, and V scale degrees in specific holes (I in holes 1-2, IV in holes 4-5, V in holes 7-8) to directly enable contemporary music scales while maintaining traditional playability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The harmonica is segmented into functional zones based on scale degrees, with blow reeds and draw reeds assigned specific pentatonic functions. This segmentation allows players to access different scales (major, minor, blues) by selecting different hole combinations, thereby improving adaptability to various musical styles

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If Richter Tuning is used, then the traditional note configuration is maintained, but six essential notes (F, F, G#, C, D#, A#) are absent

Engineering Contradiction:
Improvenumber of available notesVSAvoidtraditional tuning configuration
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent merges the I, IV, and V pentatonic scales into a single harmonica configuration. By positioning these scale degrees in specific holes and assigning them to both blow and draw reeds, the instrument simultaneously provides access to major, minor, and blues scales, effectively combining multiple scale systems in one instrument

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Each hole is designed to serve multiple functions by providing different scale degrees on blow and draw. For example, hole 1 provides the I degree on blow and the IV degree on draw, allowing the same physical hole to access different scales and thereby increasing the total number of available notes

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

3Adaptability or versatility

If Richter Tuning is used, then the traditional blow-draw configuration is maintained, but trill and glissando sections are limited

Engineering Contradiction:
Improvenumber of trill and glissando sectionsVSAvoidnote arrangement complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent preliminarily positions notes in a configuration that anticipates and facilitates trill and glissando execution. By arranging pentatonic scales linearly across adjacent holes with consistent blow-draw patterns, the instrument prepares multiple trill and glissando sections in advance, allowing players to execute these techniques without complex finger movements

Inventive Principle:
Principle #10Preliminary action
