Solution Overview

Problem

Conventional drum sets are cumbersome and time-consuming to set up and transport due to multiple components requiring separate containers, limiting their portability and ease of use, especially for drummers who want to play a cajon without sacrificing other drum components.

Innovation Solution

A portable drum kit system featuring a bass cajon with attachments for various drum components and a convertible storage container that transforms into a seat, allowing all components to be coupled to or stored within the container, which includes wheels and a handle for easy transport and setup, with detachable attachments and a cajon pedal for enhanced playability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional drum sets use multiple separate components and containers, then each component can be optimized for its specific function, but the overall system becomes complex and time-consuming to set up and transport

Engineering Contradiction:

Improvedrum component functionalityVSAvoidnumber of components and containers

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple drum components (cajon, seat, storage container, attachments) into a single integrated unit. The cajon serves as both the bass drum and seating surface, while the storage container houses all other drum components. This merging eliminates the need for multiple separate containers and reduces setup complexity while maintaining full drum kit functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The cajon serves multiple functions: it acts as the bass drum for playing, provides a seat for the drummer, and serves as the base structure for mounting other drum components. The storage container also serves dual purposes as both protection during transport and as the drumming platform when opened. This multi-functionality reduces the overall number of components needed.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If conventional drum sets use multiple separate transport containers, then each component can be protected independently, but multiple trips and extensive setup time are required

Engineering Contradiction:

Improvecomponent protectionVSAvoidsetup time and transport trips

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

All drum components are consolidated into a single storage container with a unified protective structure. The container features a rigid shell that protects all contents during transport, eliminating the need for multiple separate containers. This single-container approach allows the entire drum kit to be transported in one trip and set up by simply opening the container and attaching components.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If a cajon is used as a bass drum, then portability and simplicity are improved, but the ability to play other drum components simultaneously is limited

Engineering Contradiction:

Improveportability and simplicityVSAvoiddrum component integration

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The drum kit is segmented into modular components that can be independently attached to the cajon. The storage container includes separate compartments and mounting points for the snare drum, tom-toms, cymbals, and other accessories. This segmentation allows each component to be securely mounted and played simultaneously with the cajon, while maintaining the portability and simplicity of the integrated design.

Inventive Principle:

Principle #1Segmentation

4Productivity

If all drum components are integrated into one container, then transport efficiency is improved, but the complexity of integrating and securing components increases

Engineering Contradiction:

Improvetransport efficiencyVSAvoidintegration and securing mechanisms

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The storage container is pre-configured with molded compartments, mounting brackets, and securing mechanisms during manufacturing. These preliminary arrangements ensure that all drum components have designated locations and can be securely attached without requiring complex field assembly. The pre-integrated design simplifies the user's task to merely placing components into their predetermined positions and securing them with provided fasteners.

Inventive Principle:

AI summary

A portable drum kit system is configured to be converted from a transport configuration to a drumming configuration. The drum kit system includes a cajon with a plurality of other drum components and a convertible storage container that converts to a seat when in a drumming configuration. The portable drum kit system is easy to transport in one trip, as all the components are coupled to, configured in or on, the convertible storage container that has a set of wheels and a handle. The portable drum kit eliminates the need for expensive and bulky drum covers, cymbal cases typically required for transportation of these components. The drum kit may include a snare drum, tom tom, hi-hat, cymbal and a tambourine. The cajon may be configured to produce only bass frequencies and may include high and mid tone sound absorbing material within the cajon.
