Percussion Instrument Support Structure Vibration Isolation

Solution Overview

Problem

Existing support structures for percussion instruments fail to effectively suppress vibrations transferred to the floor surface while maintaining stability, especially when used on carpeted surfaces or when the instrument is subjected to impacts from pedal devices.

Innovation Solution

The support structure employs first vibration isolating members made of elastic material to lift the percussion instrument above the floor, reducing vibrations transferred from the instrument and pedal device to the floor by dampening them through the vibration isolating effect, while maintaining stability by placing the support member directly on the floor.

1Stability of the object's composition

If a rigid leg structure is used to stably support the pad device, then stability is improved, but vibrations transferred to the floor surface increase

Engineering Contradiction:

ImprovestabilityVSAvoidvibrations transferred to floor surface

Core Design Contradiction:

Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The support structure is divided into two functional segments: rigid support legs for stability and separate vibration isolating members for vibration reduction. The vibration isolating members are attached to the lower ends of the support legs, creating a segmented system where each component performs its specific function without compromising the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Vibration isolating members made of elastic material serve as intermediaries between the rigid support structure and the floor surface. These intermediaries absorb and dampen vibrations, preventing them from being transferred to the floor while allowing the rigid structure to maintain its stability.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A support structure for a percussion instrument has a support member configured to suppress the transfer of vibrations to the floor surface, and provide stability during performance. The entire percussion instrument and a portion or all of the pedal device are elastically supported above the floor, on the support member through the first vibration isolating members. Vibrations from the percussion instrument member and the pedal device are dampened by the first vibration isolating members. The first vibration isolating members are provided between the support member and the percussion instrument member, to suppress the transfer of vibrations to the floor surface, while the support member is stably supported on the floor surface.
