Solution Overview

Problem

Existing pet toys often lack durability and functionality, as they either break easily or do not provide a sustainable treat-dispensing mechanism, leading to limited play and consumption options for pets.

Innovation Solution

Designing toys with expandable inserts made from edible materials that fit within a housing, which can be expanded using catalysts such as heat or microwave energy, securely coupling the insert to the housing, allowing pets to play and consume the treat component while the housing remains reusable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional pet toys are made from simple materials, then they are easy to manufacture, but they lack durability and break easily

Engineering Contradiction:
ImprovedurabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The toy is divided into two functional components: a durable housing that provides structural integrity and an edible insert that provides engagement and treat-dispensing functionality. This segmentation allows each component to be optimized independently - the housing for durability and the insert for functionality - resolving the contradiction between strength and ease of manufacture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The toy combines inedible housing material (providing durability) with edible insert material (providing engagement and treat-dispensing). This composite structure allows the toy to simultaneously achieve high durability through the housing and high functionality through the edible insert, resolving the contradiction between strength and manufacturing complexity.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If pet toys provide sustainable treat-dispensing mechanism, then they extend play and consumption options, but they lack durability and break easily

Engineering Contradiction:
Improvetreat-dispensing functionalityVSAvoiddurability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

By separating the treat-dispensing function into a removable edible insert from the structural housing, the insert can be designed for maximum functionality while the housing provides durability. The insert can be refilled or replaced, extending play options without compromising the durability of the housing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insert material properties are specifically designed to change during use - transitioning from intact to consumed - while the housing maintains constant structural properties. This parameter differentiation allows the treat-dispensing mechanism to be highly adaptable while the housing remains reliably durable.

Inventive Principle:
Principle #35Parameter changes

3Duration of action of stationary object

If toys are designed to be reusable with refillable treats, then they extend use duration, but they become more complex in structure

Engineering Contradiction:
Improveuse durationVSAvoidstructural complexity
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The removable insert design allows the treat-containing component to be separated from the housing, enabling easy refilling and replacement. This segmentation extends use duration by allowing multiple inserts to be used with a single housing while keeping the overall structure relatively simple and modular.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insert is designed to fit within the housing structure, creating a nested configuration. This nesting approach allows the toy to be compact when not in use while providing expandable functionality through the removable insert, extending use duration without proportionally increasing structural complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A toy for a pet generally includes a housing defining an opening, and an insert configured to fit at least partly within the opening of the housing. The insert is expandable from a first configuration in which the insert is capable of freely moving into and/or out of the opening of the housing to a second configuration in which the insert is inhibited from moving out of the opening of the housing. In some aspects, the insert is configured to substantially fill the opening of the housing when in the second configuration. In some aspect, the housing may have multiple openings, each capable of receiving an insert. And, in some aspects, the insert is expandable from the first configuration to the second configuration by heating the insert or exposing the insert to microwave energy.
