Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing rawhide roll toys for pets are prone to quick consumption, leading to digestive issues and staining, as pets can easily access and chew the ends, causing rapid depletion and potential harm, and they lose interest due to fading flavors and undesirable materials.

Innovation Solution

A non-edible cover device that encases a rawhide roll, providing small access windows and scent windows to maintain pet interest while preventing end access and rotation, using a bone-shaped design with pin projections to secure the roll and reduce staining.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a rawhide roll is provided without a cover, then the pet can easily access and chew the ends, but the rawhide roll is quickly consumed leading to digestive issues and staining

Engineering Contradiction:

Improveaccess to rawhide rollVSAvoidsafe consumption control

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The rawhide roll is segmented into controlled access points through the cover structure. The cover divides the rawhide roll into multiple smaller access windows, preventing the pet from accessing large portions at once. This segmentation allows the pet to chew only small amounts at a time, extending the product life and preventing digestive issues from consuming large pieces.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cover acts as an intermediary device between the pet and the rawhide roll. It mediates the interaction by providing controlled access windows that limit how the pet can access the rawhide, preventing direct access to the ends and controlling the consumption rate to ensure safety.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the rawhide roll is left exposed, then the pet can chew freely, but the flavor diminishes quickly and the pet loses interest

Engineering Contradiction:

Improvechewing activityVSAvoidpet interest duration

Core Design Contradiction:

ProductivityVSDuration of action of moving object

Solution Approach 1:

The cover segments the rawhide roll into multiple small access windows distributed along its length. This allows the pet to chew at multiple locations rather than consuming from one end, distributing the chewing activity and extending the duration the pet remains interested in the toy.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cover structure is designed to be dynamic in its interaction with the pet's chewing. As the pet chews through one access window, the cover allows access to other windows, creating a dynamic chewing experience that maintains pet interest over extended periods compared to a static exposed roll.

Inventive Principle:

Principle #15Dynamics

3Reliability

If a cover is added to encase the rawhide roll, then access is controlled and life is extended, but the device complexity increases

Engineering Contradiction:

Improvesafe consumption controlVSAvoidcover structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The cover structure serves multiple functions simultaneously: it protects the rawhide roll ends, provides controlled access windows, prevents rotation, and extends product life. By combining these functions into a single device, the complexity increase is justified by the multiple benefits provided without requiring separate components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The cover appears to use a flexible material structure that can be molded into the bone-shaped design with integrated access windows. This flexible shell approach allows the cover to conform to the rawhide roll while providing structural control, achieving protection and access control without rigid complex mechanisms.

Inventive Principle:

Principle #30Flexible shells and thin films

4Productivity

If the rawhide roll is freely accessible, then the pet can chew continuously, but staining of furniture and surfaces occurs

Engineering Contradiction:

Improvechewing engagementVSAvoidsaliva staining

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The cover extracts and isolates the rawhide roll from direct contact with surrounding surfaces. By enclosing the rawhide in a protective cover with controlled access windows, the saliva and moisture from chewing are contained within the cover structure rather than being deposited on furniture and surfaces, eliminating the staining problem while maintaining chewing engagement.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A cover device that houses, protects and safely and economically dispenses an edible product, such as a rolled rawhide. The cover device substantially encases an edible rolled product and effectively prevents the pet from accessing the ends of the product. Relatively small access windows provide chewing access to the edible rolled product. The cover body has a hollow cavity and openings allowing access to the rolled product. The rolled product can be prevented from rotating within the cavity by one or more pin projections extending within the hollow cavity.
