Modular Cajon Drum Kit for Portable Full-Set Functionality

Solution Overview

Problem

Traditional drum sets are large, expensive, and not ideal for students or classroom settings due to their size and complexity, making them impractical for teaching and portability.

Innovation Solution

A series of drum sets built with convertible top and bottom modules based on a cajon, allowing for a portable, all-inclusive setup that can be easily assembled and disassembled, incorporating adjustable components and modular design for various configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional drum set is used, then complete drum kit functionality is achieved, but size and space requirements increase significantly

Engineering Contradiction:

Improvedrum kit functionalityVSAvoidspace occupation

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The drum set is divided into separate modular components including a cajon base unit, removable top module, and bottom module. Each module can be independently configured, allowing the complete drum kit functionality to be achieved through selective assembly of modules rather than requiring a full traditional drum set configuration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cajon base unit serves multiple functions: it acts as a bass drum when played with a pedal, a hand-played percussion instrument when struck directly, and a seat for the drummer. The removable top and bottom modules can be attached to create various drum configurations, making a single device replace multiple traditional drum components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a traditional drum set is used, then complete drum kit functionality is achieved, but cost increases significantly

Engineering Contradiction:

Improvedrum kit functionalityVSAvoidcost

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The cajon base unit serves multiple functions: it acts as a bass drum when played with a pedal, a hand-played percussion instrument when struck directly, and a seat for the drummer. The removable top and bottom modules can be attached to create various drum configurations, making a single device replace multiple traditional drum components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple drum functions are merged into a single cajon-based system. The bass drum pedal mechanism is integrated with the cajon, and the removable modules provide additional drum surfaces and cymbal mounting capabilities, consolidating what would traditionally require separate instruments into one unified setup.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If a traditional drum set is used, then complete drum kit functionality is achieved, but portability decreases

Engineering Contradiction:

Improvedrum kit functionalityVSAvoidportability

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The drum set is divided into separate modular components including a cajon base unit, removable top module, and bottom module. Each module can be independently configured, allowing the complete drum kit functionality to be achieved through selective assembly of modules rather than requiring a full traditional drum set configuration.

Inventive Principle:

Principle #1Segmentation

AI summary

A drum set comprising a cajon, a convertible top module and a convertible bottom module is provided. The cajon can have a top side, a bottom side, a striking side, an opposing resonant side, and two other sides. The top module can include a top mounting member removably attached over the top side of the cajon, the top mounting member has at least two top clamps configured to clamp at least two sides of the cajon. The top module also has a plurality of upward extending component mounting shafts removably attached to the top mounting member. The top module has one or more percussion modules configured to removably attach to one or more of the plurality of component mounting shafts. The bottom module can include a bottom mounting member removably attached under the bottom side of the cajon. The bottom mounting member has at least two bottom clamps configured to clamp at least two sides of the cajon. A drum kick assembly can be removably attached to the bottom mounting member and positioned on the striking side of the cajon and including a beater positioned to strike the striking side of the cajon to produce a sound. A hi-hat pedal assembly can be removably attached to the bottom mounting member and positioned on the resonant side of the cajon.
