Solution Overview

Problem

Existing pet treat dispenser toys lack variety and engagement for pets, as they often have fixed track configurations that do not provide sufficient challenge or interaction.

Innovation Solution

A spherical toy with rotatable hemi-spherical halves that can switch between two different track configurations, featuring undercut loop tracks with a combination inlet/outlet, allowing a roller member to be retained within the tracks until released through a specific opening, enhancing interaction and challenge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed track configurations are used in pet treat dispenser toys, then the structure is simple and easy to manufacture, but the toy lacks variety and engagement for pets

Engineering Contradiction:

Improvetrack configuration varietyVSAvoidtoy structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The toy employs two rotatable hemi-spherical halves that can rotate relative to each other around a central axis, dynamically changing the track configuration from a first position to a second position. This dynamic mechanism allows the same physical structure to provide multiple different track paths, increasing variety and engagement without requiring multiple separate toys or excessively complex designs.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple different track configurations are provided, then pet engagement and variety are improved, but the device complexity increases

Engineering Contradiction:

Improvetrack path varietyVSAvoidtoy manufacturing

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The toy is divided into two separate hemi-spherical halves, each containing a set of track segments. By segmenting the track system into modular halves that can be independently manufactured and then assembled, the design achieves multiple track configurations through simple relative rotation, rather than requiring complex integrated structures that would be difficult to manufacture.

Inventive Principle:

Principle #1Segmentation

3Reliability

If undercut loop tracks are used to retain the roller member, then the roller member remains securely within the track, but the track design becomes more complex

Engineering Contradiction:

Improveroller member retentionVSAvoidtrack design

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The track segments incorporate asymmetric undercut profiles with gaps positioned at specific locations. This asymmetric design allows the roller member to be retained within the track loop through the undercut geometry, while the gap provides a controlled release point. The asymmetric undercut structure achieves reliable retention with relatively simple geometric modifications to the track segments.

Inventive Principle:

Principle #4Asymmetry

AI summary

A toy comprising a sphere having a spherical first-half and a spherical second-half which are rotatable relative to one another from a first position to a second position. Each half includes a plurality of track segments. In the first position, a first position track includes at least one track segment of each half. In the second position, a second position track includes at least one track segment of each half, wherein at least one of the track segments is different from the first position track, whereby the first position track and the second position track have at least partially different track configurations.
