Drum Holder Attachment Relocating Load to Tension Bolt

Solution Overview

Problem

Existing microphone holders attached to the rim of a drum add excess load, causing uneven tension to the drum head and affecting the tone of the drum sound, especially when attached to rims with thin edges, making secure attachment difficult.

Innovation Solution

A holder attachment system that secures components to the drum using a holding part connected to an attaching unit attached to the tension bolt, reducing the load on the rim and allowing for adjustable attachment to minimize tension effects on the drum head.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a microphone holder is attached to the rim of the drum, then the microphone can be secured to the drum, but excess load is added to the rim causing uneven tension on the drum head

Engineering Contradiction:

Improvesecure attachmentVSAvoiddrum head tension uniformity

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The invention extracts the attachment function from the rim structure and relocates it to the tension bolt, which is a separate component already present on the drum. The holder attachment is attached to the tension bolt rather than the rim, thereby removing the harmful load from the rim while maintaining secure attachment capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The tension bolt serves as an intermediary component between the holder attachment and the drum structure. Instead of directly attaching the holder to the rim, the tension bolt mediates the connection, distributing the load through its threaded structure and reducing concentrated stress on the rim and drum head.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a microphone holder is attached to the rim, then the microphone can be held securely, but attachment becomes difficult on rims with thin edges

Engineering Contradiction:

Improvesecure attachmentVSAvoidattachment difficulty

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The holder attachment designed for the tension bolt can be universally applied to drums regardless of rim thickness, since the tension bolt provides a standardized attachment point. The attachment mechanism engages with the tension bolt's threaded portion, making rim thickness irrelevant to the attachment process.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention extracts the attachment function from the rim structure and relocates it to the tension bolt, which is a separate component already present on the drum. The holder attachment is attached to the tension bolt rather than the rim, thereby removing the harmful load from the rim while maintaining secure attachment capability.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If the rim position is adjusted to change drum head tension, then the tone can be tuned, but the added load from the holder attachment interferes with tension adjustment

Engineering Contradiction:

Improvetone adjustment capabilityVSAvoidtension adjustment accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The invention extracts the attachment function from the rim structure and relocates it to the tension bolt, which is a separate component already present on the drum. The holder attachment is attached to the tension bolt rather than the rim, thereby removing the harmful load from the rim while maintaining secure attachment capability.

AI summary

A holder attachment for a drum secures a component to a drum, adds no excess load on the rim of the drum, and reduces effects on the tension applied to the drum head. The holder attachment for the drum includes a holding part configured to hold a component to be attached to the drum, and an attaching unit to be attached to the tension bolt of the drum. The holding part is connected to the attaching unit.
