V-Shaped Percussion Support Frame Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic percussion instruments often tilt and fall due to inadequate support, hindering player movement and limiting pedal placement at the feet.
Innovation Solution
A percussion instrument with a support frame structured like the letter 'V' provides stability by absorbing force at the central vertical frame, allowing space for pedals and enabling rotatable arms for compact folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a support member is extended from the feet of the posts toward the player side to prevent tilting, then the stability of the percussion instrument is improved, but it hinders the player and limits the positions of pedals at the feet
Solution Approach 1:
The support frame adopts an asymmetric V-shaped configuration with the central vertical frame positioned closer to the player than the rear vertical frames. This asymmetric arrangement creates open space at the player's feet while the central frame's position allows it to effectively absorb impact forces, preventing tilting without obstructing player movement or pedal placement.
Solution Approach 2:
The support frame transitions from a conventional horizontal support arrangement to a three-dimensional V-shaped structure with vertical frames at different positions. The central vertical frame is positioned forward and closer to the player, creating a spatial configuration that provides both stability through force absorption and operational freedom by leaving the foot area open.
2Ease of operation
If the support frame is structured like the letter 'V' with the central vertical frame at the vertex, then space is created at the feet of the player for effective use, but the structure complexity increases
Solution Approach 1:
The support frame is segmented into three independent vertical frames (central and two rear frames) connected by transverse frames. This segmentation allows the central vertical frame to be positioned forward to create foot space, while each segment independently contributes to the overall stability, making the complex V-shaped structure functionally manageable.
3Stability of the object's composition
If the central vertical frame absorbs the force from pad hits, then the support frame is prevented from tilting and falling, but the force concentration on the central frame increases
Solution Approach 1:
The central vertical frame and the two rear vertical frames are merged into a unified V-shaped support structure through transverse frames. This merging allows the impact force on the central frame to be distributed to the rear frames, reducing stress concentration while maintaining the central frame's primary role in preventing tilting.

AI summary
A percussion instrument includes at least one pad and a support frame supporting the pad. The support frame includes a central vertical frame, a left vertical frame located in a left rear direction of the central vertical frame when viewed from the player side, a right vertical frame located in a right rear direction of the central vertical frame when viewed from the player side, a left transverse frame extending between the central vertical frame and the left vertical frame and connecting the central vertical frame with the left vertical frame, and a right transverse frame extending between the central vertical frame and the right vertical frame and connecting the central vertical frame with the right vertical frame. The at least one pad is connected with the central vertical frame.
