Foldable Pedal Musical Instrument Stand With Serration Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional musical instrument stand assemblies with foldable pedals are cumbersome and inconvenient to fold, as they require loosening a bolt, moving a positioning element upward, and resecuring it, which can lead to deformation or cracking if not done carefully.
Innovation Solution
The design incorporates first and second circular serrations on support rods and side frames, allowing for easy adjustment of the main stand body's inclination and simplified folding by engaging these serrations, eliminating the need for complex bolt manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the main stand body is disposed vertically with respect to the floor, then the structure is simple and stable, but the musician's striking angle and position are affected when the distance is increased
Solution Approach 1:
The main stand body is designed with an inclined configuration rather than strictly vertical, allowing the striking surface to be positioned at an optimal angle for musicians. The support rod can be adjusted to different inclination angles while maintaining structural stability, thus providing adaptability without excessive complexity.
2Ease of operation
If the positioning element is moved upward to fold the pedal, then the pedal can be folded, but the process is complicated and inconvenient requiring bolt loosening and resecuring
Solution Approach 1:
The bolt connection is extracted from the folding mechanism. Instead of using bolts that require loosening and resecuring, the positioning element uses a snap-fit or elastic retention system that allows the pedal to be folded by simply moving the positioning element upward without any fastener manipulation.
Solution Approach 2:
The positioning element is designed with elastic deformation capability, allowing it to automatically engage and disengage from the support rod during folding. The elastic structure provides self-retention during normal use and self-release during folding, eliminating the need for manual bolt operation.
3Reliability
If the positioning element slides down accidentally, then the pedal remains fixed, but deformation or cracking may occur if folding force is applied with the positioning element in wrong position
Solution Approach 1:
The positioning element incorporates visual or tactile feedback mechanisms that indicate its correct position. When the positioning element is in the proper position for folding, it provides clear feedback to the user. If it has slid down to the wrong position, the feedback mechanism alerts the user to avoid applying folding force, thus preventing deformation or cracking.
Solution Approach 2:
The design includes protective features that prevent damage before it occurs. The positioning element has built-in indicators or interlocks that prevent the folding action from being initiated unless the element is in the correct position, thereby cushioning against potential deformation or cracking of the limit position portions.

AI summary
A musical instrument stand assembly with a foldable pedal includes a main stand body, and the main stand body includes a main rod, and the bottom of the main rod includes two support rods each with a recession, and the recession includes a first circular serration; two side frames, and a sidewall of each side frame includes a protrusion and a second circular serration at the protrusion, and each side frame is installed by engaging each protrusion with the recession of each support rod, such that the first and second circular serrations are engaged with each other. With the design of rotably engaging the two side frames and the two support rods, the main stand body of the musical instrument has the function of adjusting its inclination with respect to a vertical position, and the effect of conveniently folding the pedal of the musical instrument.
