Solution Overview

Problem

Standard electric guitars are limited in accommodating more than 9-10 strings due to their flat fretboard design, making it difficult for players to reach all strings comfortably and switch between different types of strings like guitar, bass, or other instruments seamlessly during performance.

Innovation Solution

An electric stringed musical instrument with a rotating neck portion that can accommodate multiple strings, including both guitar and bass strings, equipped with a motor-controlled mechanism for smooth rotation and adjustable frets, allowing for easy access and switching between string types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a flat fretboard construction is used to accommodate additional strings, then the number of strings can be increased, but the player's ability to reach across strings and maintain proper thumb support deteriorates

Engineering Contradiction:
Improvenumber of stringsVSAvoidplayer comfort and accessibility
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent transitions from a two-dimensional flat fretboard to a three-dimensional cylindrical neck configuration. Strings are arranged radially around the neck circumference, allowing players to access strings from multiple angles and positions, thereby maintaining playability while accommodating up to 32 strings.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The neck is made rotatable, allowing dynamic repositioning of the string set relative to the player's hand. This enables players to rotate the neck to optimal playing positions, maintaining ergonomic comfort even with a large number of strings that would be impossible on a static flat fretboard.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If a standard guitar design is used, then the instrument structure remains simple, but the ability to switch between different string types (guitar, bass, etc.) deteriorates

Engineering Contradiction:
Improveinstrument structureVSAvoidstring type switching capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The cylindrical neck design with radial string arrangement creates a universal platform that can accommodate different string types and configurations. The same neck structure can hold guitar strings, bass strings, or other string types, eliminating the need for separate instruments while maintaining structural simplicity.

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

Solution Approach 2:

The rotatable neck allows dynamic reconfiguration of string accessibility. Players can rotate the neck to bring different string sets into optimal playing position, enabling seamless transitions between different instrument types (guitar, bass, etc.) without physical reconfiguration or carrying multiple instruments.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple instruments are carried to switch between guitar and bass, then string type versatility is improved, but the player's burden and complexity of equipment increases

Engineering Contradiction:
Improvestring type switching capabilityVSAvoidnumber of instruments to carry
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple instrument functions (guitar, bass, and other stringed instruments) into a single cylindrical neck structure. Different string types can be installed on the same neck, and the rotatable design allows players to access different string sets as needed, effectively combining multiple instruments into one while reducing equipment burden.

Inventive Principle:
Principle #5Merging (Combining)
