Pet Grooming Tool with Blunt Catchment Hooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet grooming tools often cause discomfort or injury to pets and groomers while attempting to remove mats, as they either cut healthy fur or pull it out, and are not effective in distinguishing between loose and attached fur, leading to skin issues and inefficiency.
Innovation Solution
A pet grooming tool with a contoured handle and long tines featuring short, shallow, blunt-tipped catchment hooks that target mats in the undercoat without cutting or pulling attached fur, designed to incrementally untangle and remove mats while minimizing impact on the guard coat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If long tines are used to reach the undercoat, then the tool can access mats in the undercoat, but the tines can get caught in mats causing discomfort or injury to the animal
Solution Approach 1:
The patent applies local quality by giving different characteristics to different parts of the tines. The tines have blunt tips instead of sharp points, and feature curved hooks at specific locations to engage mats gently without penetrating or scratching the skin. This localized modification of tine properties allows them to reach the undercoat effectively while minimizing harm to the animal.
2Productivity
If blade-like tines with sharpened leading edges are used to cut mats, then mat removal effectiveness is improved, but healthy attached fur is also cut and removed
Solution Approach 1:
The patent uses local quality by creating hooks with specific geometric characteristics at particular locations on the tines. These hooks have curved surfaces and specific angles that allow them to catch and gradually work through mats without cutting. The hook geometry is designed to engage only loose matted fur while passing through healthy attached fur without cutting it.
Solution Approach 2:
The patent applies parameter changes by modifying the physical characteristics of the tine tips from sharp blades to curved hooks with specific dimensional parameters. The hooks have controlled depth, curvature radius, and spacing that enable selective engagement of mat material while maintaining compatibility with healthy fur structure, thus changing the interaction parameters between the tool and different types of fur.
3Productivity
If arrays of arcuate blades with sharpened leading edges are used, then mats can be cut apart, but the tool indiscriminately cuts healthy attached fur along with loose matted fur
Solution Approach 1:
The patent applies local quality by positioning hooks at specific locations on the tines rather than using continuous blades. The hooks are spaced and oriented to create zones of mat engagement that are localized and controlled, allowing the tool to target only the matted areas while leaving healthy fur untouched.
4Ease of operation
If tightly grouped arrays of short bristles are used, then the coat can be raked uniformly, but the tool cannot effectively reach the underlying undercoat
Solution Approach 1:
The patent applies segmentation by dividing the grooming function into two distinct components: the long tines that reach through the guard coat to access the undercoat and engage mats, and the shorter hook structures that perform the actual mat removal. This segmentation allows each component to be optimized for its specific function while working together as an integrated system.

AI summary
A pet grooming tool including a handle and long tines terminating in short, shallow catchment hooks. When the tines are drawn through the pet's fur, the catchment hooks untie tangled and matted fur incrementally without snagging and compounding the whole mass and without cutting through or removing attached fur. The hooks include a blunt leading edge that grabs and unties fur entanglements without cutting the fur. The long tines deliver the catchment hooks to the under coat while leaving the guard coat alone. The handle is ergonomic with a contoured shape for ease of use, effective engagement of the tines with the fur and a pleasing grooming experience for the pet owner and the pet.
