Foldable Drum Stand Arms for Low Snare Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drum stands either cannot set a snare drum at a low position or are not compact in their retracted form due to design limitations, such as high support positions and extended curved arms.
Innovation Solution
A drum stand with a foldable tripod and arms that can transition from an in-use, radially extended form to a retracted, compact form, featuring adjustable arms and a mechanism to change the diameter of the drum support to fit different snare drum sizes, allowing for low positioning and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the base ends of the stays are raised along the drum supporting-side pipe together with the annular body to support the snare drum, then the snare drum can be supported at a relatively high position, but the snare drum cannot be set at a low position and the top head of the snare drum is likely to be located higher than a desired position
Solution Approach 1:
The patent applies the dynamics principle by making the arm structure movable and adjustable. The arms can be raised and lowered along the post, and their radial position can be adjusted, transforming a static support structure into a dynamic one that can adapt to different drum positions and sizes, thereby resolving the contradiction between stable support and position adjustability
Solution Approach 2:
The patent segments the support structure into multiple independent components: the post, multiple arms that can move independently, and adjustable radial positions. This segmentation allows each component to be optimized for its specific function while collectively providing both stable support and versatile adjustability for different drum configurations
2Adaptability or versatility
If the arms are curved more greatly toward the distal end to avoid interference with the arms when the snare wires are loosened, then the snare drum can be supported at a lower position, but the curved portions of the arms extend by a relatively great distance from the post in a retracted form
Solution Approach 1:
The arms are designed with dynamic curvature that can change during retraction. When retracted, the curved portions are positioned closer to the post, reducing the overall volume occupied. This dynamic adjustment of arm curvature allows the structure to maintain both low-position support capability and compact retracted form
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by positioning the curved portions of the arms in different spatial dimensions during retraction. The arms are arranged to fold along the post axis while maintaining their functional curvature, effectively using vertical space to reduce horizontal projection and achieve a more compact retracted form
3Ease of operation
If a large space is provided between the three arms and the bottom surface of the snare drum to avoid interference, then the snare drum can be positioned lower, but the arms must be curved more greatly which reduces retracted compactness
Solution Approach 1:
The radial position of the arms is made dynamically adjustable, allowing the arms to move closer to the drum during use when snare wire access is needed, and to retract closer to the post when not in use. This dynamic adjustment eliminates the need for permanent large spacing while maintaining ease of operation when required
Solution Approach 2:
The arm structure is designed to perform multiple functions: supporting the drum at various positions, allowing snare wire access when needed, and retracting to a compact form for storage. The adjustable radial position and curvature enable the same structure to fulfill all these functions without requiring separate mechanisms for each function

AI summary
The drum stand includes a stand main body, a drum support, and an attachment that attaches the drum support to the stand main body. The drum support is composed of a first arm and two second arms that open and close with respect to the first arm. The first and second arms all extend obliquely and linearly from near the upper end of a post toward a bottom surface of a snare drum.
