Toy Car Limiting Member for Universal Track Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current toy cars face limitations due to the need for precise matching between toy cars and tracks, leading to production and design constraints, as well as increased manufacturing costs and complexity.
Innovation Solution
A toy car design featuring a housing assembly with rotatable wheels and a limiting member that abuts against the side surfaces of track blocks, allowing different shapes of toy cars to be adapted to the same track building blocks, thereby reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional track design precisely matches the size and structure of the toy car, then the toy car can smoothly run on the track, but this greatly limits the use of toy car products and increases manufacturing complexity and costs
Solution Approach 1:
The patent applies universality by designing a standardized limiting member with limiting wheels that can be universally adapted to different track blocks. The limiting member features a uniform limiting wheel diameter (0.5-2.5 cm) that can engage with blocks of various sizes, allowing a single component design to work across multiple track configurations without requiring custom-matched components for each toy car model.
Solution Approach 2:
The patent segments the toy car into functional modules: a housing assembly, a detachable limiting member, and limiting wheels. This segmentation allows the limiting member to be independently designed and replaced, enabling different toy cars to use the same standardized track blocks while maintaining smooth operation through modular compatibility.
2Reliability
If traditional track design precisely matches the size and structure of the toy car, then the toy car can smoothly run on the track, but different sizes or types of toy cars require different tracks, greatly increasing production costs
Solution Approach 1:
The limiting member is designed as a universal component that can interface with various track blocks regardless of their specific dimensions. The standardized limiting wheel size range (0.5-2.5 cm) ensures compatibility across different block types, allowing manufacturers to produce a single limiting member design that serves multiple toy car models, thereby reducing production costs while maintaining smooth operation.
Solution Approach 2:
The patent specifies a parameter range for the limiting wheel diameter (0.5-2.5 cm) rather than a fixed size. This parameter variation allows the same limiting member design to accommodate different block sizes within the range, enabling cost-effective mass production of standardized components that can adapt to various track configurations without requiring custom manufacturing for each size variant.
3Reliability
If traditional track design precisely matches the size and structure of the toy car, then the toy car can smoothly run on the track, but in the event that one of the toy cars or toy tracks is damaged, the user is forced to purchase an entire new product
Solution Approach 1:
The limiting member is designed as a detachable, segmented component that can be separated from the housing assembly. This segmentation enables easy replacement of just the damaged limiting member or limiting wheels without requiring replacement of the entire toy car, significantly improving ease of repair and reducing the need to purchase completely new products.
Solution Approach 2:
The limiting member is designed with detachable connections to the housing assembly, allowing it to be dynamically removed and replaced. This dynamic design enables users to swap out damaged components independently, facilitating easy repair and extending the lifecycle of the toy car system without forcing complete product replacement.

AI summary
A toy car includes a housing assembly and a limiting member. The housing assembly is provided with a plurality of wheels rotatable with respect to the housing assembly. The plurality of wheels is configured for engaging on an upper surface of a block and rolling along the upper surface of the block. The limiting member is connected to the housing assembly. The limiting member is configured for abutting against a side surface of the block, and the limiting member is used for limiting the plurality of wheels on the upper surface of the block.
