Grooming Comb with Rounded Teeth for Skin Injury Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current metal comb designs for animal grooming are prone to causing injuries and damage to the animal's skin due to sharp edges and tips, and are difficult to maintain and clean, leading to potential health issues.
Innovation Solution
A comb with two sets of teeth, one for thick and one for fine fur, featuring rounded tips and edges, made by moulding or 3D printing, ensuring gentle engagement with the fur without skin injury and facilitating easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If metal combs with machined teeth are used, then scraping power is improved for removing dead hairs, but sharp edges and tips cause injuries to the animal's skin
Solution Approach 1:
The patent applies curvature by rounding the tips and edges of the comb teeth. Instead of sharp machined edges, the teeth have rounded contours that eliminate cutting action while maintaining the ability to remove dead hairs and dandruff through gentle scraping, thus preventing skin injuries.
Solution Approach 2:
The patent changes the geometric parameters of the teeth by providing anti-injury roundings at the tips and over a portion of the length of the edges. This parameter modification transforms the teeth from sharp cutting edges to rounded gentle contact surfaces, reducing harmful cutting power while preserving beneficial scraping function.
2Power
If metal combs with machined teeth are used, then scraping power is improved, but the comb becomes difficult to maintain and clean
Solution Approach 1:
The patent changes the geometric parameters of the teeth by providing anti-injury roundings at the tips and over a portion of the length of the edges. This parameter modification transforms the teeth from sharp machined edges to rounded gentle contact surfaces, reducing harmful cutting power while preserving beneficial scraping function.
3Power
If metal combs with machined teeth are used, then scraping power is improved, but the sharp edges can break hairs and form bald patches
Solution Approach 1:
The patent applies curvature by rounding the tips and edges of the comb teeth. Instead of sharp machined edges, the teeth have rounded contours that eliminate cutting action while maintaining the ability to remove dead hairs and dandruff through gentle scraping, thus preventing skin injuries.
Solution Approach 2:
The patent changes the geometric parameters of the teeth by providing anti-injury roundings at the tips and over a portion of the length of the edges. This parameter modification transforms the teeth from sharp cutting edges to rounded gentle contact surfaces, reducing harmful cutting power while preserving beneficial scraping function.
4Adaptability or versatility
If two sets of intercalated teeth are provided, then brushing effectiveness is improved for different fur types, but device complexity increases
Solution Approach 1:
The patent divides the comb into two distinct sets of intercalated teeth: a main set with longer teeth for dense/thick fur, and a secondary set with shorter, thinner teeth for fine/less dense fur. This segmentation allows each set to be optimized for specific fur types, improving versatility while maintaining a unified comb structure.
Solution Approach 2:
The comb design provides multi-functionality by incorporating two sets of teeth with different characteristics in a single comb body. The main set handles dense fur while the secondary set handles fine fur, allowing one comb to serve multiple grooming purposes for different fur types and seasons.

AI summary
Disclosed is a comb having a lamellar body and including, along a toothed edge, teeth able to penetrate the coat of hair. The comb eliminates injuries caused to the animal by sharp teeth, eliminating fur damage while also improving the treatment of the hair coat and to improve brushing performance by adapting to the hair coat of each animal, in each season. To this end, the teeth of the two sets of teeth A and B, which are positioned one on each side of the mid plane P of the body and the teeth of which sets are intercalated with one another, have anti-injury roundings at the tips and over part of the length of the edge corners leading from these tips and are delimited between a flat external face and a curved extreme internal face, the tooth set B being finer and provided with shorter teeth.
