Extruded Spiral Dog Chew with Meat Syrup Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edible dog chews are expensive to manufacture due to the method and high chicken content, and often do not last long or are unhealthy.
Innovation Solution
A method involving extruding a starch-based mixture with animal-based materials through a mold to form a lengthened chew interior with a spiral shape, cutting it into defined lengths, drying, and coating with a fresh meat and glycerin syrup to create a durable and affordable edible dog chew.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If chicken is rolled out and baked with organic eggs and olive oil to form dog chews, then the chews are healthy and edible, but the manufacturing cost is high
Solution Approach 1:
The patent changes the material parameters by substituting expensive chicken-based ingredients with starch-based materials (corn starch, wheat flour, sweet potato, tapioca flour, potato, or rice flour) that contain over 50% plant-based starches. This parameter change in material composition dramatically reduces manufacturing cost while maintaining edibility and safety for dogs.
Solution Approach 2:
The invention replaces expensive, resource-intensive chicken material with cheaper, readily available starch-based materials. These alternative materials are more cost-effective and can be produced at lower cost, directly addressing the high manufacturing cost issue of traditional chicken-based chews.
2Duration of action of stationary object
If traditional methods are used to manufacture dog chews, then the chews are simple to produce, but they do not last long
Solution Approach 1:
The patent introduces a spiral-shaped cross-section design for the chew interior material, created by extruding through a mold with a spiral shaped inward projection. This curved, non-linear geometry increases chew complexity and durability, making the chews last longer while engaging the dog's chewing behavior more effectively.
Solution Approach 2:
The invention applies different materials and structures to different parts of the chew: a starch-based chew interior with spiral geometry for durability, and a fresh meat syrup coating for palatability. This local differentiation of material properties enhances both chew longevity and dog appeal.
3Ease of operation
If a spiral shaped cross section with lengthwise through openings is created, then chewability is enhanced, but the manufacturing process becomes more complex
Solution Approach 1:
The spiral-shaped cross-section is achieved by incorporating a spiral shaped inward projection into the extrusion mold design. This curved geometric feature creates the desired spiral pattern in the extruded chew material, enhancing chewability through increased structural complexity and engagement.
Solution Approach 2:
The extrusion process creates lengthwise through openings in the chew interior material, forming a porous structure. These openings enhance chewability by providing multiple chewing surfaces and pathways, while also allowing the meat syrup coating to penetrate and infuse the interior during the coating process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method reduces production costs and enhances chew durability by using a spiral-shaped design and a glycerin-based coating, resulting in a longer-lasting and healthier dog chew option.
Implementation Method 1
a. extruding a first edible mixture through a mold in a first direction to form a lengthened chew interior material
Implementation Method 2
c. drying the cut chew interior material to form a chew interior
Implementation Method 3
d. coating the chew interior with a second edible mixture different from the first edible mixture; wherein said extruded chew interior material has a spiral shaped cross section and lengthwise through openings; wherein the coating coats the ends of the first edible mixture to close the through openings
