Solution Overview

Problem

Existing toy track sets lack the ability to dynamically change track orientations without user intervention, limiting the complexity and excitement of toy vehicle routes.

Innovation Solution

A toy track set design featuring rotatably coupled track sections with tubular or cylindrical connectors, allowing the second track section to rotate relative to the first, enabling continuous travel paths between different orientations without disconnection, such as between vertical and horizontal loop configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If track sections are fixed in position, then the track structure is simple and stable, but the route complexity and excitement are limited

Engineering Contradiction:
Improveroute complexityVSAvoidtrack structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making track sections rotatable relative to each other through cylindrical connectors. This allows the track orientation to change dynamically during play, enabling vehicles to transition between vertical and horizontal loops without requiring complex reconfiguration or additional track pieces, thus increasing route complexity while maintaining structural simplicity

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If track sections are rotatably coupled, then the route complexity and excitement increase, but the track structure becomes more complex

Engineering Contradiction:
Improveroute complexityVSAvoidtrack structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the track into modular sections that can be independently rotated and reconfigured. Each track section connects to others through standardized cylindrical connectors, allowing complex routes to be built from simple, interchangeable components rather than requiring a single complex integrated structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cylindrical connectors serve multiple functions: they provide structural connection between track sections, enable rotational movement for orientation changes, and maintain continuity of the travel path. This multi-functionality reduces the need for additional specialized components, thereby increasing route complexity without proportionally increasing structural complexity

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

3Adaptability or versatility

If the track orientation is fixed, then the manufacturing is simple, but the play experience lacks variety

Engineering Contradiction:
Improveplay experience varietyVSAvoidmanufacturing simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The rotatable track sections allow the same manufactured components to create multiple track orientations and route configurations. The cylindrical connectors enable smooth rotational transitions without requiring different manufactured parts for different orientations, thus providing play experience variety while maintaining manufacturing simplicity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the orientation parameter of track sections through rotation rather than requiring different manufactured components for each orientation. This allows the same track sections to be manufactured once and then reconfigured into various orientations (vertical, horizontal, angled) through rotational movement, enhancing play experience variety without complicating manufacturing

Inventive Principle:
Principle #35Parameter changes

AI summary

Toy track sets for toy vehicles are disclosed. A toy track set for a toy vehicle may include a first track section having a first travel surface and a first tubular connector at a first connecting end of the first travel surface. The toy track set may further include a second track section that is configured to be rotatably coupled to the first tubular connector. The second track section may include a second travel surface having first and second travel portions. The second track section may be configured to rotate relative to the first track section between a first position in which the first travel surface forms a continuous travel path with the first travel portion, and a second position in which the first travel surface forms a continuous travel path with the second travel portion.
