Solution Overview

Problem

Existing motorcycle toys lack customization options with interchangeable swing arms and rear tires that allow users to modify the style and mobility of the toy, as they do not enable detachment and interchangeability of these components for simulating movement.

Innovation Solution

A series of custom motorcycle toys with removable swing arms and interchangeable rear tires, where both front and rear tires can rotate, allowing for customization and mobility through a kit including multiple swing arms, rear tires, a kickstand, screws, and a chain for decorative purposes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If motorcycle toys have fixed swing arms and rear tires, then the structure is simple and easy to manufacture, but the customization options are limited

Engineering Contradiction:
Improvecustomization optionsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The motorcycle toy is divided into separable components: the swing arm can be detached from the rear tire using a screw mechanism. This segmentation allows users to interchange different swing arms and rear tires to create customized motorcycle configurations, directly addressing the need for adaptability while maintaining manageable structural complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The swing arm and rear tire assembly is designed as a universal interface that can accommodate multiple variations of swing arms and rear tires. The standardized mounting mechanism allows any swing arm to work with any rear tire, providing multi-functionality and extensive customization options without requiring complex specialized connections for each variant

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the rear tire is fixed to the swing arm, then the structure is stable, but the ability to interchange swing arms and customize the motorcycle is reduced

Engineering Contradiction:
ImproveinterchangeabilityVSAvoidstructural stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connection between the swing arm and rear tire transitions from a fixed static state to a dynamic state where it can be easily assembled and disassembled. The screw mechanism provides a reliable connection during use (maintaining structural stability) while allowing quick interchange when needed (enabling adaptability), thus resolving the contradiction between stability and interchangeability

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If motorcycle toys have non-rotating tires, then the structure is simpler, but the ability to simulate movement is reduced

Engineering Contradiction:
Improvemovement simulationVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The tire assembly is segmented to include a rotatable component that can independently rotate on the swing arm. This segmentation allows the tire to simulate movement through rotation while keeping the rest of the motorcycle structure simple and stationary, providing movement simulation capability without requiring complex mechanical mechanisms throughout the entire toy

Inventive Principle:
Principle #1Segmentation
