Solution Overview

Problem

Existing tooth-cleaning bone products for pets suffer from poor palatability, inefficient processing, and inadequate tooth-cleaning effectiveness, often leading to pets avoiding these products and potential oral health issues.

Innovation Solution

A pet chew product featuring a tubular basic strip with an axial channel of polygonal cross-section, which forms a gear-like meshing structure when squeezed, enhancing stability and tooth-cleaning efficacy, and incorporating a flaky flavored strip for improved palatability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If animal skin products are used for tooth-cleaning bones, then the product structure is simple, but the texture is very dry and hard, causing pets' teeth to be scratched or oral mucosa to be damaged

Engineering Contradiction:

Improveproduct structureVSAvoidoral mucosa damage

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the physical and chemical parameters of the chew product by using extruded processed products with specific hardness and elasticity parameters rather than traditional animal skin products. The product maintains appropriate hardness for cleaning while ensuring safety through controlled elasticity and texture parameters.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses composite materials consisting of multiple ingredients including flour, starch, protein, and other additives in specific proportions to create an extruded product that combines the cleaning effectiveness of hard structures with the safety of softer, more elastic materials.

Inventive Principle:

Principle #40Composite materials

2Reliability

If solid injection-molded bone products are used, then the tooth-grinding and cleaning effect is achieved, but the biting surface is slippery and pets may swallow the whole bone causing throat blockage

Engineering Contradiction:

Improvetooth cleaning effectVSAvoidthroat blockage risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs curved and rounded structural designs in the chew product shape, avoiding sharp edges and flat surfaces. The product features a bone-like shape with rounded contours that prevent throat blockage while maintaining effective tooth-cleaning surfaces through strategically placed ridges and textures.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent applies different surface qualities to different parts of the product - the biting surfaces have specific textures for effective tooth cleaning, while the overall structure maintains appropriate elasticity and rounded shapes to prevent choking hazards.

Inventive Principle:

Principle #3Local quality

3Productivity

If the extrusion process is used to prepare tooth-cleaning bone, then the production efficiency is improved, but the palatability is poor and pets are reluctant to eat it

Engineering Contradiction:

Improveprocessing efficiencyVSAvoidpalatability

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent uses composite materials in the extrusion process, combining multiple ingredients including flour, starch, protein, and flavoring agents in specific proportions to create a product that maintains production efficiency while significantly improving palatability and appeal to pets.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent optimizes the extrusion process parameters including temperature, pressure, and ingredient ratios to produce a product with improved texture, taste, and aroma characteristics that enhance palatability while maintaining the efficiency of continuous extrusion production.

Inventive Principle:

Principle #35Parameter changes

4Shape

If manual knotting is used to form bone shape, then the product shape is achieved, but the processing time is excessive and efficiency is limited

Engineering Contradiction:

Improvebone shapeVSAvoidprocessing efficiency

Core Design Contradiction:

ShapeVSProductivity

Solution Approach 1:

The patent incorporates the bone shape formation directly into the extrusion molding process, creating the final bone-like shape in a single continuous operation rather than requiring separate manual knotting steps. This preliminary action of shaping during extrusion dramatically improves production efficiency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the manual mechanical knotting process with an automated extrusion molding system that forms the bone shape through controlled material extrusion and setting, eliminating labor-intensive manual operations while maintaining consistent product quality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
