Musical Instrument String Clamping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Musical instruments like the electric bass guitar have note distances that are suboptimal for human hand size and flexibility, limiting less experienced musicians' ability to play desired pieces due to physical constraints.
Innovation Solution
A musical instrument design featuring a string with clamping mechanisms that can be controlled to change the string's frequency by dividing it into portions, allowing for easier note transitions and accommodating varying hand sizes through a clamping mechanism with camming surfaces and expansion springs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional string instruments are designed with fixed note positions, then the instrument structure is simple, but musicians with limited hand flexibility cannot easily reach distant notes
Solution Approach 1:
The patent implements a dynamic clamping mechanism that can move along the string to change the vibrating length. The clamping member is positioned on a movable carriage that can be actuated by a control member, allowing the effective string length to be dynamically adjusted during playing. This dynamic adjustment enables musicians to easily transition between notes without requiring large hand movements, while the mechanism maintains relative structural simplicity through the use of a single movable clamping member rather than multiple fixed frets.
2Ease of operation
If the distance between notes is reduced to accommodate smaller hands, then ease of operation improves, but the instrument cannot accommodate standard musical ranges
Solution Approach 1:
The dynamic clamping mechanism allows the vibrating length of the string to be continuously adjusted by moving the clamping member along the string. This enables the instrument to accommodate standard musical ranges while maintaining short effective distances between playable notes, as the clamping member can be positioned at intermediate points along the string. The control member actsuation system allows musicians with smaller hands to easily access all notes within the standard range without requiring large hand stretches.
Solution Approach 2:
The patent segments the string into a vibrating portion and a non-vibrating portion by introducing a movable clamping member. This segmentation allows the effective playing length to be independently controlled, enabling the instrument to provide both short distances between adjacent playable notes and the ability to access the full standard musical range by repositioning the clamping member to different locations along the string.
3Adaptability or versatility
If a clamping mechanism is added to enable flexible note selection, then adaptability improves, but the device complexity increases
Solution Approach 1:
The patent implements a dynamic clamping mechanism with a single movable clamping member that can be actuated by a control member. The clamping member is mounted on a carriage that moves along the string, and its position is controlled by actuating the control member, which triggers the clamping mechanism to grip or release the string at the desired location. This single movable clamping member provides flexible note selection across the entire string length while maintaining relatively simple construction compared to systems with multiple fixed frets or complex electronic interfaces.
Applied Scientific Principles
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 less experienced musicians to play complex pieces by allowing for easier manipulation of string frequencies and note transitions, overcoming physical limitations and instrument design constraints.
Implementation Method 1
the second camming surface of the second clamping member interacts with the first camming surface of the first clamping member to transfer force between the first clamping member and the second clamping member
Implementation Method 2
The clamping mechanism can include, for example, an expansion spring configured to bias the second clamping member

AI summary
A musical instrument including a vibrating member, such as a string, and a clamping mechanism. The clamping mechanism can include a first clamping member and a second clamping member. The first clamping member and the second clamping member can move between a first, undamped position to a second, clamped position. The clamping mechanism divides the vibrating member into a first portion and a second portion when the clamping mechanism is in the second, clamped position.
