Multi-Layer Pet Chew Composition for Longer, Safer Chewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet chews, such as real animal bones, rawhide, and synthetic materials, pose health risks, have short chew times, and fail to adequately simulate the texture and flavor of natural bones, leading to quick consumption or abandonment.
Innovation Solution
A multi-layered pet chew composed of edible materials and hardened polymers, mimicking the structure of natural bones, with an outer layer simulating meat and an inner core mimicking marrow, using injection molding techniques to extend chew time and enhance flavor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If real animal bones are used, then flavor, nutrition, and chew time are improved, but health risks and hygiene issues worsen
Solution Approach 1:
The chew is segmented into multiple layers with different materials - an outer edible layer providing flavor and nutrition, and an inner non-edible polymer core providing structural integrity and extended chew time. This segmentation allows each layer to fulfill its specific function without the drawbacks of real bones.
Solution Approach 2:
The invention uses composite materials combining edible components (meat, plant-based materials) with non-edible hardened polymers. This composite structure mimics the experience of chewing real bones while eliminating health risks associated with bone shards and spoilage.
2Duration of action of moving object
If rawhide is used, then chew time is extended, but health effects and chemical contamination worsen
Solution Approach 1:
The invention changes the material parameters by using hardened polymers with controlled hardness and durability characteristics. The polymer core is engineered to withstand prolonged chewing while the outer edible layer provides safe, chemical-free flavor and nutrition.
3Object-affected harmful factors
If plant-based materials are used, then health benefits are improved, but chew time and jaw exercise worsen
Solution Approach 1:
The edible plant-based or meat layer is nested around the inner polymer core. The dog chews through the outer edible layer to access the inner core, which provides extended chew time and jaw exercise. This nested structure combines the health benefits of edible materials with the longevity of polymer materials.
4Duration of action of moving object
If hardened polymers are used, then chew time and texture are improved, but flavor and attractiveness worsen
Solution Approach 1:
Different parts of the chew have different qualities - the outer layer is designed with high flavor appeal and edibility to attract the dog, while the inner core provides the hardened texture and extended chew time. Each layer's properties are optimized for its specific function in the chewing experience.

AI summary
A pet chew having an innermost core composed of one or both of edible meat and plant-based material, a middle member surrounding the innermost core and composed of a hardened non-consumable composite material, and an outermost layer surrounding the middle member and composed of one or both of edible meat and plant-based material.
