Solution Overview

Problem

Existing pet grooming tools are inefficient in removing loose hair from furry pets without causing damage to the pet's coat.

Innovation Solution

A pet grooming tool with a handle and multiple pet engageable portions featuring teeth and edge segments, designed to simultaneously engage and remove loose fur, with specific tooth and guard configurations to protect the pet's coat.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing pet grooming tools are used to remove loose hair, then grooming function is provided, but they are inefficient and may damage the pet's coat

Engineering Contradiction:

Improveefficiency of removing loose hairVSAvoiddamage to pet's coat

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The grooming tool is divided into multiple pet engageable portions (first, second, third, and fourth portions) with teeth arranged in parallel rows. Each portion independently engages loose fur, allowing simultaneous multi-point contact with the pet's coat. This segmentation increases efficiency while the distributed structure reduces concentrated stress that could damage the coat.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The teeth in each pet engageable portion have specific geometric characteristics (spacing, length, and arrangement) optimized for engaging loose fur. The edge segments between teeth provide localized protection and guidance. This local optimization ensures effective loose fur removal while preventing damage to anchored hair through carefully designed tooth geometry and spacing.

Inventive Principle:

Principle #3Local quality

2Productivity

If multiple pet engageable portions are used to increase efficiency, then loose fur removal improves, but device complexity increases

Engineering Contradiction:

Improveloose fur removal efficiencyVSAvoidnumber of pet engageable portions

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Multiple pet engageable portions are merged into a single integrated grooming tool head, with all portions secured to a common head portion. The teeth in different portions are arranged in parallel and spaced to work simultaneously during a single stroke. This combining approach achieves high productivity while maintaining a unified, manageable device structure rather than requiring multiple separate tools.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Each pet engageable portion serves the same function of engaging and removing loose fur, but their combined presence creates a multi-point engagement system. The tool achieves enhanced productivity through this multi-functional arrangement while maintaining operational simplicity, as all portions work together in a single coordinated motion during grooming.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If teeth are arranged closely to maximize engagement, then loose fur capture improves, but risk of cutting non-loose hair increases

Engineering Contradiction:

Improveloose fur capture capabilityVSAvoidcutting non-loose hair

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The edge segments positioned between adjacent teeth act as protective elements that cushion and guide the teeth during engagement. These edge segments prevent the teeth from directly contacting and potentially cutting anchored hair, providing a protective buffer zone while still allowing effective engagement of loose fur through the tooth structure.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
