Keyboard Stand With Floating V-Arms and Sliding Clamps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing musical equipment stands, such as X-type, Z-type, T-type, and C-type stands, face issues with stability, compactness, and ease of folding, particularly when adjusting height, which affects their ability to support various keyboard and DJ coffin sizes and user configurations.
Innovation Solution
A stand with 'floating' V-shaped arms and legs that slide vertically in an extruded aluminum column, locked by clamps, allowing for independent height adjustment without changing the width between arms and legs, and a compact folding mechanism using interlocking clamps and guide pins for easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the height of the stand is increased, then the keyboard mounting height is raised, but the lateral distance between opposing arms and legs decreases, compromising stability
Solution Approach 1:
The stand is divided into independent adjustable segments (arms and legs) that can be positioned separately. Each arm and leg can be independently adjusted to maintain optimal lateral distance from the central column regardless of height, resolving the contradiction between height and stability by decoupling these two parameters.
Solution Approach 2:
The stand employs dynamic adjustment mechanisms allowing the lateral distance between arms and legs to be changed independently of height. This enables the structure to adapt its geometry to maintain stability at any height position, transforming a static geometric constraint into a dynamically adjustable configuration.
2Ease of operation
If the stand is designed to be portable and foldable, then ease of transport is improved, but the stability and support capability may be compromised
Solution Approach 1:
The stand structure is segmented into modular components that can be independently folded and collapsed. This segmentation allows the stand to be disassembled into a compact form for transport while maintaining the structural integrity and stability features when deployed in its operational configuration.
Solution Approach 2:
The stand transitions between two dynamic states: a compact folded state for portability and an expanded stable state for operation. The adjustment mechanisms allow smooth transition between these states, enabling the stand to achieve both portability and stability at different times as needed.
3Adaptability or versatility
If adjustable support structures are added to accommodate different users and keyboard sizes, then versatility is improved, but device complexity increases
Solution Approach 1:
The stand employs universal adjustment mechanisms that serve multiple functions: height adjustment, lateral distance adjustment, and angle adjustment. These multi-functional mechanisms reduce the need for separate adjustment systems for each parameter, thereby increasing versatility while controlling overall complexity.
Solution Approach 2:
The stand uses dynamic adjustment systems that allow continuous variation of support parameters rather than fixed positions. This enables the stand to adapt to different keyboard sizes and user preferences while using a relatively simple mechanism that can be adjusted on-demand rather than requiring multiple pre-configured options.

AI summary
A stand for a musical keyboard is both stable in a deployed configuration and conveniently compact and portable in a collapsed configuration. The separation of the arms and legs may not change in width as the height of the stand is adjusted. The stand has two “floating” V's, one for the arms and one for the legs. These components slide vertically in slots in a central column and are locked in place with clamps that wrap around the column. To adjust the height of the stand, a user loosens either or both the top and/or bottom clamp (arm clamp or leg clamp) and slides the associated floating V up or down along the center column, then re-tightening the clamp when adjustments are finished. For transport and storage, the user loosens each clamp and rotates the arms or legs in, towards the column.
