Multi-Layer Pet Chew Structure for Longer Safe Chew Time
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 flavor, texture, and longevity of natural animal 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 animal bones, with an outer layer simulating meat and an inner core simulating marrow, using injection and extrusion techniques to extend chew time and enhance dental health.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If real animal bones are used, then flavor and nutrition are improved, but health risks increase due to spoilage and sharp shards
Solution Approach 1:
The patent creates a synthetic chew toy that copies the appearance, texture, and structure of real animal bones without using actual bone material. The multi-layered design replicates the visual and tactile properties of bones while eliminating the health risks associated with real bones such as spoilage and sharp shards.
Solution Approach 2:
The patent uses composite materials consisting of multiple layers including outer coating, middle layer, and inner core, each made from different edible and non-edible materials. This composite structure provides the desired flavor and texture while ensuring safety by eliminating harmful components found in real bones.
2Duration of action of moving object
If rawhide is used, then chew time is extended, but health effects worsen due to unhealthful chemicals and ingestion risks
Solution Approach 1:
The patent employs composite materials with multiple functional layers: an outer coating layer providing flavor and initial chewability, a middle layer providing structural integrity and extended chew time, and an inner core providing nutritional value. This composite structure achieves long chew time without the harmful chemicals associated with rawhide.
Solution Approach 2:
The patent changes the material parameters from natural rawhide to synthetic and processed materials that are safer for consumption. The multi-layered structure modifies the physical and chemical properties to provide extended chew time while eliminating harmful substances through controlled material selection and processing.
3Object-affected harmful factors
If plant-based materials are used, then health effects are improved, but chew time decreases and jaw exercise is reduced
Solution Approach 1:
The patent combines plant-based materials with safe synthetic materials in a multi-layered composite structure. The outer and inner layers can be plant-based for health benefits, while the middle layer provides structural support for extended chew time and jaw exercise, achieving both health improvement and adequate chew duration.
4Duration of action of moving object
If hardened composites are used, then texture and longevity are improved, but flavor decreases making them less attractive to dogs
Solution Approach 1:
The patent applies different material qualities to different layers: the outer coating layer uses flavorful materials to attract the dog, the middle layer uses hardened composite materials for structure and longevity, and the inner core provides nutritional content. This local differentiation of material properties ensures both flavor appeal and extended chew time.

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.
