Solution Overview

Problem

Conventional drums are cumbersome to transport due to their one-piece design, making them difficult to carry and transport, as they are either heavy or occupy significant space when multiple smaller drums are moved.

Innovation Solution

A drum design featuring shell members that can be easily assembled and disassembled using magnetic components and joining mechanisms, allowing for convenient assembly and disassembly, and enabling the drum to be broken down into manageable parts for transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional drum is made as a one-piece design with drumhead connecting to shell, then the drum structure is simple and strong, but the drum becomes difficult to disassemble and transport

Engineering Contradiction:

Improveease of assembly and disassemblyVSAvoiddrum structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The drum is divided into separate modular components: shell members (which can be further segmented), drumheads, magnetic components, and joining components. This segmentation allows the drum to be easily assembled and disassembled while maintaining structural integrity when connected.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The joining components are inserted into openings in the shell members, creating a nested structure where smaller components fit within larger ones. This nested design enables easy assembly and disassembly while maintaining a compact form when connected.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Quantity of substance

If a larger drum is used to reduce the number of drums, then the drum produces better sound, but the drum becomes heavier and consumes more space for transport

Engineering Contradiction:

Improvenumber of drumsVSAvoiddrum weight

Core Design Contradiction:

Quantity of substanceVSWeight of moving object

Solution Approach 1:

The drum system is segmented into multiple smaller drums that can be individually transported. Each drum maintains its functional integrity through magnetic coupling, allowing users to transport only the necessary number of drums rather than moving one large drum.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The drum structure transitions from a fixed one-piece design to a dynamic modular system where components can be connected or separated. This dynamic configuration allows users to adapt the number and arrangement of drums based on transport needs while maintaining acoustic performance.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If a conventional one-piece drum is used, then the drum structure is stable and strong, but the drum consumes significant space when transported

Engineering Contradiction:

Improvedrum structure stabilityVSAvoiddrum transport volume

Core Design Contradiction:

Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The drum is segmented into modular components that can be disconnected and stored more compactly. When connected through magnetic coupling and joining components, the segments form a stable structure comparable to traditional drums, but when separated, they occupy significantly less transport volume.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The drum system enables dynamic transformation between connected (stable, functional) and disconnected (compact, portable) states. The magnetic components and joining mechanisms maintain structural stability when connected while allowing easy separation for compact storage and transport.

Inventive Principle:

Principle #15Dynamics

AI summary

A drum of the present invention comprises: a shell having a plurality of shell members, wherein the upper rim of the shell is provided with a first magnetic component, and wherein the lower rim of the shell is provided with a second magnetic component; a first drumhead provided with a third magnetic component corresponding to the first magnetic component; and a second drumhead provided with a fourth magnetic component corresponding to the second magnetic component. The shell members use a first joining component and a second joining component to be joined with one another so as to form the shell. Furthermore, by magnetism between the first magnetic component and the third magnetic component and magnetism between the second magnetic component and the fourth magnetic component, the first drumhead, the second drumhead and the shell can be joined with one another. A drum of the present invention is advantageous in that it is easy to assemble and disassemble the drum, and accordingly, it is highly convenient whether to carry or to transport the drum.
