Toy Wheel Assembly Modular Design for Interchangeable Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional toy wheel assemblies are integral to toy bodies, limiting the ability to change toy configurations since they cannot be easily attached or detached.
Innovation Solution
A toy wheel assembly comprising a first wheel, a second wheel, and a cylindrical shaft that connects them perpendicularly, allowing for rotation around a joint axis, with a predetermined gap to accommodate a toy part's groove, enabling the shaft to rotate freely without a permanent connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the toy wheel assembly is made as an integral part of the toy body, then the structural stability is improved, but the adaptability and ease of reconfiguration deteriorate
Solution Approach 1:
The wheel assembly is divided into separate components (wheels, shaft, mounting features) that can be independently attached to and removed from the toy body, transforming an integral structure into a modular segmented design that maintains stability while enabling reconfiguration
Solution Approach 2:
The toy body and wheel assembly are pre-equipped with complementary mounting features (protrusions and recesses) that enable straightforward attachment and detachment operations, allowing easy reconfiguration without complex assembly procedures
2Reliability
If the toy wheel assembly is physically connected to the toy body, then the reliability is improved, but the ease of operation for reconfiguration deteriorates
Solution Approach 1:
The connection system transitions from a fixed permanent bond to a dynamic reversible connection that can be easily engaged and disengaged, allowing the wheel assembly to be reliably attached during operation but readily reconfigured when needed
Solution Approach 2:
Mounting features such as protrusions and recesses act as intermediary elements between the wheel assembly and toy body, providing a reliable connection interface that facilitates both secure attachment and easy detachment without requiring additional tools or complex mechanisms

AI summary
A toy wheel assembly including a first wheel having a first surface and a second surface, a second wheel having a third surface and a fourth surface and a cylindrical shaft. The cylindrical shaft having a first edge and a second edge. The first wheel is connected to the second wheel by the cylindrical shaft. The first edge of the cylindrical shaft is perpendicularly mounted to a center of the second surface of the first wheel, and the second edge of the cylindrical shaft is perpendicularly mounted to a center of the third surface of the second wheel. Such that the first wheel and the second wheel rotate around a joint axis in unison, and the cylindrical shaft maintains a predetermined gap between the second surface and the third surface.
