Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing motorcycles with integrated drum sets are side-heavy due to the placement of the drum set as a sidecar, which reduces drivability and prevents consistent turning.

Innovation Solution

A motorcycle tricycle design with a centrally integrated drum set and rear steering mechanism, allowing the drummer to play during operation, featuring mirrored drum sets on both sides and rear controls for improved balance and control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the drum set is placed as a sidecar, then the drum set can be integrated with the motorcycle, but the motorcycle becomes side-heavy which reduces drivability and prevents consistent turning

Engineering Contradiction:

Improvedrum set integrationVSAvoiddrivability and turning consistency

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies asymmetry by providing different drum set configurations for left and right sidecars. The sidecar with the drummer position includes a complete drum set with bass drum, snare drum, toms, and cymbals, while the opposite sidecar has a reduced configuration without the bass drum. This asymmetric arrangement balances the weight distribution and allows the drummer to play while maintaining motorcycle drivability and turning consistency.

Inventive Principle:

Principle #4Asymmetry

2Ease of operation

If a complete drum set is integrated centrally, then the drummer can be positioned centrally about the motorcycle, but the device complexity increases

Engineering Contradiction:

Improvecentral drummer positioningVSAvoidintegrated drum set configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the drum set into modular components distributed across the motorcycle frame and sidecars. The bass drum is mounted on the frame below the driver's seat, while other drums and cymbals are positioned on the sidecars. This segmentation allows central positioning of the drummer while managing device complexity through modular, distributed arrangement of drum set components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent utilizes vertical space by mounting the bass drum on the frame below the driver's seat, effectively using the third dimension (vertical space) to accommodate drum set components. This dimensional approach allows central drummer positioning without increasing horizontal footprint or overall device complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the drum set is mirrored on both sides, then the drummer can play during operation, but the weight distribution becomes unbalanced

Engineering Contradiction:

Improvedrummer operation capabilityVSAvoidweight distribution balance

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent deliberately employs asymmetry to resolve the weight distribution problem. Instead of mirroring the complete drum set on both sidecars, the invention places the full drum set configuration on one sidecar (the one with the drummer position) and a reduced configuration on the opposite sidecar. This asymmetric arrangement enables the drummer to play during operation while maintaining proper weight distribution and balance.

Inventive Principle:

Principle #4Asymmetry
