Rotary Plate Support Mechanism for String Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for string instruments are cumbersome and require unnecessary attachment and detachment processes, leading to spatial inefficiency and increased assembly time, as they cannot be easily stored within the instrument's casing.
Innovation Solution
A support device comprising fixing plates, first and second rotary plates with hinge parts, and rotary members that allow for multiple positions and folding, enabling secure attachment to the instrument while allowing for compact storage within the instrument's casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guitar supporter is attached to allow comfortable playing posture, then playing comfort is improved, but device complexity and assembly time increase
Solution Approach 1:
The support device is merged with the guitar body by fixing it to the lower plate, eliminating the need for separate attachment structures. The first and second rotary plates are combined into a single integrated rotating mechanism that provides both support and adjustment functions, reducing overall structural complexity while maintaining playing comfort.
Solution Approach 2:
The rotary plate mechanism serves multiple functions: it provides structural support for the guitar, enables height adjustment of the head, and allows folding for compact storage. This multi-functionality reduces the need for separate components, simplifying the overall device structure while improving ease of operation.
2Ease of operation
If a guitar supporter with height adjustment is provided, then playing comfort is improved, but assembly time and storage difficulty increase
Solution Approach 1:
The rotary plates are pre-configured with hinge parts and fixing plates during manufacturing, so that height adjustment can be achieved simply by rotating the plates to desired positions rather than requiring complex assembly steps. The fixing plates are pre-positioned to guide the rotation and locking process, reducing assembly time.
Solution Approach 2:
The rotary plate mechanism allows dynamic height adjustment during use by rotating the plates to different positions. The hinge connections enable smooth rotation while maintaining structural integrity, providing flexible height adjustment without requiring disassembly or complex manipulation, thus reducing the time needed to adjust and assemble the device.
3Ease of operation
If a guitar supporter is attached to improve playing posture, then playing comfort is improved, but storage space efficiency deteriorates
Solution Approach 1:
The first and second rotary plates are designed to nest within each other when folded. The smaller rotary plate can be positioned inside or against the larger rotary plate, creating a compact nested configuration that minimizes storage volume while maintaining full support functionality when deployed.
Solution Approach 2:
The rotary plate mechanism can dynamically transition between an extended configuration for providing full support during playing and a folded configuration for compact storage. The hinge connections allow smooth transformation between these states, enabling the device to adapt its volume based on usage requirements without compromising playing posture support.

AI summary
Disclosed are a support device for a string instrument and a string instrument having the same, the support device being easily stored without an unnecessary separate attachment/detachment process. The support device for a string instrument includes: fixing plates fixed to a body of a string instrument; a first rotary plate rotatably connected to the fixing plates; and a second rotary plate rotatably coupled to the first rotary plate, wherein the first rotary plate has a shape corresponding to one part of a side plate of the body, and the second rotary plate has a shape corresponding to another part of the side plate of the body which is different from one part of the side plate of the body.
