Solution Overview

Problem

Conventional toy vehicle track sets are difficult for young children to assemble and require separate connectors, which can be cumbersome and inefficient, and do not effectively accommodate a wide range of toy vehicle types and provide varied play features.

Innovation Solution

The toy vehicle track system includes track pieces with integral connectors that allow easy assembly and disassembly by young children without additional pieces, ensuring compatibility with various toy vehicles and providing a variety of play configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate connectors are used to join track pieces, then the track system can be assembled and disassembled, but the assembly process becomes complex and difficult for young children to perform independently

Engineering Contradiction:
Improveease of assemblyVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates the connector functionality directly into the track pieces themselves, merging what were previously separate components (track pieces and connectors) into a unified design. Each track piece includes built-in connection features at its ends, eliminating the need for separate connector pieces and simplifying the assembly process for children.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If integral connectors are integrated into track pieces, then assembly becomes simpler and faster, but manufacturing precision requirements increase

Engineering Contradiction:
Improveassembly speedVSAvoidconnector alignment
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The track pieces are designed with distinct functional zones: the main track body section and the integrated connector sections at the ends. This segmentation allows the connectors to be optimized for precise mating while the main body focuses on vehicle guidance, enabling modular manufacturing processes that can achieve required precision more efficiently.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If track pieces are designed to accommodate various toy vehicle types, then versatility increases, but the track design becomes more complex

Engineering Contradiction:
Improvevehicle compatibilityVSAvoidtrack design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The track pieces are designed with universal connection interfaces that can accommodate multiple toy vehicle types and shapes. The integrated connectors and track geometry are configured to work with various vehicle configurations, allowing a single track set to serve multiple play scenarios and different toy collections.

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

AI summary

A toy vehicle track piece of present application includes one or more connectors. Thus, two track pieces can be connected directly to each other without any additional pieces (e.g., without separate connectors pieces or pins). Moreover, the connectors are specifically designed so that young children can easily connect and disconnect two track pieces without parental intervention. Additionally or alternatively, the track pieces presented herein, as well as accessories associated therewith, may be designed to assemble at specific grid locations so that any configuration of track pieces can be connected together to form a closed track path.
