Dual-Angle Animal Toothbrush with Central Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional animal toothbrushes lack multiple brush heads with different sizes and orientations, fail to provide various bristle angles for efficient cleaning, and lack a central gripping mechanism for user support during dental care.
Innovation Solution
A manual toothbrush design featuring two brush heads with offset ends and a central grip, allowing for ergonomic handling and different angles for effective cleaning of animal teeth, including a tongue cleaning feature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional animal toothbrushes use a single brush head design, then the device complexity is low, but the adaptability for different animal mouth sizes and tooth configurations is insufficient
Solution Approach 1:
The toothbrush handle is segmented into multiple sections with distinct brush heads of different sizes and configurations. The first brush head has a larger size for adult animals while the second brush head has a smaller size for puppies or cats, allowing the single device to adapt to different animal mouth sizes without increasing overall device complexity
Solution Approach 2:
The toothbrush is designed with multi-functionality by incorporating multiple brush heads with different characteristics (varying sizes, bristle densities, and angles) into a single handle, enabling it to serve multiple animals of different sizes and types, thereby improving adaptability while maintaining a unified device structure
2Productivity
If conventional toothbrushes have brush heads aligned in the same direction, then the manufacturing precision is simple, but the cleaning effectiveness for different tooth surfaces is reduced
Solution Approach 1:
The brush heads are arranged asymmetrically with different orientations relative to the handle axis. The first brush head is angled at a first angle while the second brush head is angled at a second angle, creating asymmetric configurations that enable effective cleaning of different tooth surfaces (front, side, and back teeth) while maintaining straightforward manufacturing processes
3Ease of operation
If conventional toothbrushes lack a central gripping location, then the device structure is simple, but the ease of operation for users is reduced due to lack of support
Solution Approach 1:
A gripping location is added in a dimensional sense to the handle structure, creating a central recess or ergonomic feature that provides support for the user's finger. This additional dimensional element improves ease of operation by providing proper grip support while adding minimal structural complexity to the overall handle design

AI summary
A manual toothbrush that includes a handle, a first brush head, and a second brush head. The handle has a first end, a second end opposite to the first end, a grip disposed between the first and second ends of the handle, and a longitudinal axis extending through the grip, wherein each of the first and second ends is offset to the longitudinal axis. The first brush head is provided at the first end of the handle, the first brush head has a first set of bristles, the first brush head is disposed at a first angle measured relative to the longitudinal axis of the handle. The second brush head is provided at the second end of the handle, the second brush head has a second set of bristles, the second brush head is disposed at a second angle measured relative to the longitudinal axis of the handle.
