Foldable Musical Instrument Stand With Gravity Self-Locking Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable musical instrument stands often fail to securely hold instruments, leading to accidental falls, and are not easily collapsible for storage.
Innovation Solution
A foldable musical instrument stand with a supporting structure comprising a main supporting piece, side supporting pieces, connecting pieces, and L-shaped brackets, along with a gravity self-locking mechanism using elastic deformation and sliding parts to securely hold instruments without obstructing removal, and a multi-headed stand connecting multiple units for increased stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable musical instrument stand is designed to be foldable for easy storage, then the ease of storage is improved, but the stability and security of holding the instrument deteriorates
Solution Approach 1:
The stand employs dynamic components including hinged connections between the main supporting piece and side supporting pieces, allowing the structure to transition between folded and unfolded states. The brackets are designed with rotational joints that enable them to move between horizontal and vertical positions, providing both portability and stability as needed
Solution Approach 2:
The stand is divided into multiple independent segments: main supporting piece, side supporting pieces, connecting pieces, and brackets. Each segment can be independently positioned and locked, allowing the structure to be collapsed for storage or expanded and secured for use, resolving the contradiction between portability and stability
2Weight of moving object
If the stand structure is simplified for portability, then the ease of carrying is improved, but the stability and anti-fall capability deteriorates
Solution Approach 1:
The stand uses dynamic bracket mechanisms that can rotate between horizontal and vertical positions. When vertical, the brackets provide enhanced stability and anti-fall capability. The structure transitions from a simple folded state to a complex stabilized state only when needed, maintaining light weight for portability while providing stability during use
Solution Approach 2:
The brackets serve as intermediary elements between the main supporting piece and the instrument. By positioning these brackets vertically, they create an additional support layer that enhances stability without significantly increasing the overall weight of the stand structure
3Reliability
If locking mechanisms are added to prevent instrument falls, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The bracket mechanism is designed to be self-locking through its geometric configuration. When the bracket is rotated to the vertical position, its shape and the hinge constraints automatically prevent it from returning to the horizontal position, providing passive locking without additional complex mechanisms. The structure locks itself through the interplay of its own components
Solution Approach 2:
The locking mechanism is achieved through dynamic positioning rather than static locks. The brackets can be easily rotated into the vertical locked position when needed, and the same dynamic joints that enable movement also provide the locking function when properly positioned, avoiding the need for separate locking devices
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
The stand securely holds musical instruments without risk of falling and easily collapses for storage, while the multi-headed configuration enhances stability and versatility for multiple instruments.
Implementation Method 1
