Three Brush Toothbrush with Splash Guard and Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toothbrushes are inefficient in cleaning the top and sides of teeth simultaneously, particularly for individuals or animals that require assistance with oral hygiene, as they necessitate separate cleaning processes.
Innovation Solution
A toothbrush design featuring a head with three gears and brushes that rotate to contact occlusal, buccal, and lingual surfaces simultaneously, accompanied by a splash guard and optional suction tube for debris removal, allowing for comprehensive teeth cleaning in a single operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional tooth brush is used, then the structure is simple and easy to manufacture, but it cannot clean the top and sides of teeth simultaneously, requiring separate cleaning processes
Solution Approach 1:
The tooth brush is segmented into three distinct brush heads, each with a specific function: one brush head for cleaning the occlusal surface (top) of teeth, and two brush heads for cleaning the buccal and lingual sides. This segmentation allows each brush to specialize in a particular surface, enabling simultaneous cleaning of multiple tooth surfaces while maintaining manageable complexity through modular design
Solution Approach 2:
The tooth brush is designed as a multi-functional device that can clean three different tooth surfaces (occlusal, buccal, and lingual) simultaneously using three integrated brush heads. This universal design eliminates the need for multiple separate brushes or cleaning tools, improving productivity by combining what were previously separate cleaning operations into a single device
2Productivity
If brushes rotate to contact multiple surfaces simultaneously, then cleaning efficiency improves, but the device becomes more complex with gears and rotating mechanisms
Solution Approach 1:
The brush heads are designed to rotate dynamically to contact different tooth surfaces. The rotation mechanism allows the brushes to adapt their orientation automatically as they move across the occlusal, buccal, and lingual surfaces, enabling continuous cleaning contact without requiring complex fixed-position mechanisms for each surface
3Object-affected harmful factors
If a splash guard is added to reduce mess, then cleaning cleanliness improves, but the device structure becomes more complex
Solution Approach 1:
A flexible splash guard is incorporated into the tooth brush design to contain and redirect water and debris during the cleaning process. The thin film structure of the splash guard effectively reduces mess and protects the surrounding area while adding minimal structural complexity to the overall device

AI summary
Implementations of a tooth brush are provided. In some implementations, the tooth brush comprises a handle and a head attached to the handle where the head comprises three gears and three brushes attached to the three gears respectively. In some implementations, the tooth brush is configured such that one brush makes contact with the occlusal surfaces of a plurality of teeth and the remaining brushes make contact with the buccal side and lingual side of the plurality of teeth. In some implementations, the tooth brush further comprises a splash guard. In some implementations, the tooth brush further includes a suction tube to remove debris from the mouth. Methods of using the tooth brush also are provided.
