Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional percussion instruments have low versatility as they can only fix rods of one diameter in both horizontal and vertical directions, limiting their adaptability to different drum set configurations.
Innovation Solution
A percussion instrument design that includes a bracket with multiple insertion holes and tightening portions for rods of different diameters, allowing for secure attachment of horizontal and vertical rods with varying diameters using elastic deformation and sliding displacement of tightening members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single tightening portion is used in the bracket, then the structure is simple, but it can only fix rods of one diameter, reducing versatility
Solution Approach 1:
The bracket is designed with multiple tightening portions (first tightening portion for large diameter rods, second tightening portion for small diameter rods) within a single structure, enabling it to perform multiple functions of securing different rod types. This universal design allows the same bracket to adapt to various rod configurations without requiring separate brackets for each rod size.
Solution Approach 2:
The bracket's tightening mechanism is segmented into distinct first and second tightening portions, each optimized for specific rod diameters. This segmentation allows independent adjustment and optimization for different rod sizes, resolving the contradiction between structural simplicity and adaptability by dividing the function into specialized sub-components.
2Adaptability or versatility
If a tightening portion elastically deforms to tighten the rod, then the assembly is simple and stable, but it may interfere with the insertion of rods of different diameters
Solution Approach 1:
Each tightening portion is designed with locally optimized properties: the first tightening portion has elastic deformation characteristics suited for large diameter rods, while the second tightening portion has characteristics optimized for small diameter rods. This local quality differentiation ensures that each portion can properly accommodate its target rod size without interfering with the insertion process.
Solution Approach 2:
The tightening portions utilize elastic deformation as a dynamic mechanism that adapts to different rod diameters. When a rod is inserted, the appropriate tightening portion elastically deforms to match the rod's diameter, then gradually tightens as the tightening bolt is rotated. This dynamic adaptation eliminates interference during insertion while maintaining secure fixation.
3Strength
If the tightening bolt is tightened strongly, then the rod is securely fixed, but it may damage the bracket or rod
Solution Approach 1:
The tightening mechanism allows progressive adjustment of the tightening force parameter. As the tightening bolt is rotated, the tightening portion gradually elastically deforms and increases the clamping force on the rod. This controlled parameter change enables achieving strong fixation without sudden excessive force that could damage the bracket or rod, maintaining reliability while ensuring strength.

AI summary
A percussion instrument and a rod tightening method that may improve versatility are provided. The percussion instrument includes a bracket (10) including an insertion hole (11a) into which a horizontal rod (100a) is insertable and insertion holes (11b, 14a) into which a horizontal rod (100b) is insertable. The horizontal rod (100a) inserted into the insertion hole (11a) may be tightened by a first tightening portion (31) of a first tightening member (30), and the horizontal rod (100b) inserted into the insertion holes (11b, 14a) may be tightened by a second tightening portion (42) of a second tightening member (40). Thus, since a percussion instrument (1) is supportable by the two horizontal rods (100a, 100b) that extend in the same direction (horizontal direction) and have different diameters, versatility may be improved.
