Dog Toothbrush with Replaceable Chew Element for Self-Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Professional dental care for dogs is costly and requires anesthetizing, which poses risks and complications, necessitating a self-administered teeth brushing solution that is attractive and effective.
Innovation Solution
A dog toothbrush assembly that supports an elongated chew element, allowing dogs to brush their teeth naturally by engaging bristles with their teeth and gums, with easily replaceable chew elements and minimal owner intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional veterinarian dental care is provided to dogs, then dental health is improved, but cost and anesthesia risks increase
Solution Approach 1:
The device enables dogs to perform their own dental hygiene by incorporating a treat-dispensing mechanism with brushing elements. The dog's natural chewing behavior activates the brush to contact teeth and gums, eliminating the need for professional veterinary intervention and associated anesthesia risks.
Solution Approach 2:
The patent introduces a mechanical intermediary device that bridges the gap between the dog's natural chewing behavior and dental cleaning. The treat-dispensing mechanism serves as an intermediary that guides the dog's jaw motion to effectively engage brushing elements with teeth, translating natural behavior into therapeutic action.
2Reliability
If regular teeth brushing is performed on dogs, then plaque and tartar buildup is reduced, but owner time and effort increase
Solution Approach 1:
The device is designed so that dogs perform their own brushing through natural chewing motions. The treat-dispensing mechanism is positioned to engage the dog's jaw, automatically moving the brush against teeth and gums as the dog chews, eliminating the need for owner intervention and time investment.
Solution Approach 2:
The device enables continuous dental cleaning action as long as the dog is chewing the treat. Unlike manual brushing which occurs in discrete sessions, this device provides ongoing cleaning throughout the treat consumption period, maximizing hygiene effectiveness while minimizing owner involvement.
3Ease of operation
If chew elements are made attractive to dogs, then dog engagement increases, but treat visibility and accessibility may be restricted
Solution Approach 1:
The patent combines the treat dispenser and toothbrush into a single integrated device. The treat mechanism and brushing elements are merged such that the dog's interaction with the treat automatically activates the brushing function, simplifying the overall structure while maintaining high dog engagement.
Solution Approach 2:
The device serves multiple functions simultaneously: it dispenses attractive treats to engage the dog, provides mechanical brushing action for cleaning, and utilizes the dog's own jaw motion as the driving force. This multi-functionality reduces the need for separate components and complex mechanisms.

AI summary
A dog toothbrush assembly has two plastic end caps with blind cavities that face one another and receive an elongated generally cylindrical chew element which is attractive to dogs such as an edible treat or other chewable material. The end caps are connected by screw fasteners to the support member of a brush, and an array of tufts of bristles project upwardly from the support member to engage the elongated chew element. The chew element is supported with respect to the bristles such that when a dog chews on the chew element the dog's teeth also encounter and are brushed by the bristles. When the chew element is worn or consumed, an end cap is removed by releasing one of the screw fasteners, thereby giving access for insertion of a replacement chew element.
