Violin Body with Slidable Joint for Stable Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difficulty in maintaining a stable playing position and accurately changing strings on a violin due to the required physical posture and arm movements, making it challenging for adult learners to progress in playing the instrument.
Innovation Solution
A bowed string instrument design featuring a body with a shoulder pad, a body receiver, and an operative joint portion that allows slidable or rotatable movement on a spherical or curved surface, enabling stable holding and reduced effort in handling the bow and strings, with optional magnetic coupling and noise-reducing liners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a player uses the basic position to play violin, then the violin can be held between shoulder and jaw, but it becomes very difficult to maintain stable position
Solution Approach 1:
The violin holding system is segmented into multiple support points: shoulder pad for upper support, body receiver with operative joint for lower support, and the ability to independently adjust each component's position and angle, distributing the holding burden and improving overall stability
Solution Approach 2:
The operative joint portion introduces dynamic adjustment capability, allowing the body to be slidable or rotatable to adapt to different playing positions and player anatomies, transforming the static holding problem into a dynamically adjustable system
2Adaptability or versatility
If a player grips the neck with left hand while bending back and twisting, then finger positioning is possible, but the joint reaches limit of range of motion
Solution Approach 1:
The adjustable body position through operative joint allows the violin to move relative to the player's body, enabling players with limited joint flexibility to achieve proper finger positioning without excessive bending or twisting of the left arm
3Adaptability or versatility
If a player moves the bow over large angle to change between low-pitched and high-pitched strings, then all strings can be reached, but considerable skill and time are required
Solution Approach 1:
The body's ability to slide or rotate on the spherical surface of the operative joint allows the violin to reposition dynamically, enabling the player to access different strings with smaller, easier bow movements while maintaining the full range of string coverage
Solution Approach 2:
The operative joint adds rotational and sliding dimensions to the violin's position space, allowing pitch changes to be achieved not only through horizontal bow movement but also through vertical and angular adjustments of the instrument itself

AI summary
The present invention provides a bowed string instrument that allows a player to hold it in a stable manner and to handle a bow and strings without much effect. A bowed string instrument 1 has a body 102, a shoulder pad 103 connected to the body 102, a body receiver 106 disposed below the body 102 so as to receive a load of the body, and an operative joint portion 107 coupling the body 102 and the body receiver 106 to each other while allowing the body 102 to be slidable on a spherical surface. The body 102 includes a fingerboard 105, a plurality of strings 104 extending above the fingerboard 105, and a pair of bridges for supporting and tensioning the plurality of strings 104 above the fingerboard 105.
