Spiked Leg Vibration Isolation via Rubber Stopper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spiked leg structures for musical instruments and stands fail to effectively absorb vibrations, leading to incomplete sound production as vibrations are transmitted to the floor, reducing the bass drum's and hi-hat's inherent sound quality.
Innovation Solution
A spiked leg design featuring a leg member with a stopper and a spike where the proximal end of the spike is separated from the distal end of the leg member, utilizing a vibration-absorbing stopper material like rubber and a rigid spike holder to absorb and block vibrations, preventing them from reaching the floor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the distal end of the leg part is set against the floor surface to fix the bass drum position, then the bass drum is stabilized, but vibration is transmitted to the floor surface without being absorbed, reducing sound quality
Solution Approach 1:
The patent introduces a rubber stopper as an intermediary element between the leg part and the floor surface. This rubber stopper acts as a mediator that absorbs vibrations while maintaining the stabilizing function, preventing direct vibration transmission to the floor while preserving position stability.
Solution Approach 2:
The patent changes the material parameter of the stopper from rigid to elastic (rubber), which fundamentally alters the vibration transmission characteristic. This material parameter change enables the stopper to absorb vibrations through elastic deformation while still providing the necessary stabilizing force.
2Stability of the object's composition
If the spike rod is assembled to the supporting leg main part to fix the hi-hat stand position, then the hi-hat stand is stabilized, but vibration is transmitted to the floor surface via the supporting leg main part and spike rod, reducing sound quality
Solution Approach 1:
The patent introduces a rubber stopper as an intermediary element between the supporting leg main part and the floor surface. This rubber stopper acts as a mediator that absorbs vibrations while maintaining the stabilizing function, preventing direct vibration transmission to the floor while preserving position stability.
3Object-generated harmful factors
If a rubber stopper is used to absorb vibrations, then vibration absorption is improved, but the structure becomes more complex with additional components
Solution Approach 1:
The patent merges the stopper and spike into a single integrated component structure. The rubber stopper and spike are combined in such a way that they function as one unit, reducing the number of separate components while maintaining both the stabilizing and vibration-absorbing functions.
Solution Approach 2:
The rubber stopper component performs multiple functions simultaneously: it acts as a vibration absorber, a position stabilizer, and a structural support element. This multi-functionality reduces the need for separate components, simplifying the overall structure while achieving multiple objectives.

Function Achieved in This Case
Maximizes sound quality by inhibiting vibration transmission to the floor, enhancing the inherent sound of musical instruments like bass drums and hi-hats, while reducing the number of components and assembly steps, and ensuring stability and secure fixation.
Implementation Method 1
the distal end of the second leg part formed in a spike shape to abut against a floor surface... vibration of the bass drum is transmitted to the floor surface via the distal end of the leg part without being absorbed in the rubber leg

AI summary
A spiked leg includes a first leg part and a second leg part, which are leg members, and a stopper fixed to a distal end of the second leg part. The stopper includes a stopper main body, a spike holder, and a spike. In the stopper main body, a part of the stopper main body is located between a first longitudinal hole and a second longitudinal hole. Due to this, the proximal end of the spike is arranged apart from a distal end of the second leg part when the second leg part and the spike are assembled onto the stopper.
