Omnidirectional Toothbrush U-Shaped Head Multi-Roller Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toothbrushes, both manual and electric, have limited cleaning efficiency due to small brush heads that cannot effectively reach all areas of the teeth, leading to inadequate cleaning of occlusal surfaces and increased risk of dental caries, and require manual user control, which is time-consuming and inefficient.
Innovation Solution
An omnidirectional scientific toothbrush with a U-shaped brush head containing central and side brush rollers driven by a micro motor, allowing for simultaneous brushing of all teeth surfaces from the roots to the tips, including occlusal surfaces, with a built-in water-washing system and program control unit for automated brushing and washing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a small brush head is used, then the toothbrush structure is simple and cost-efficient, but the cleaning efficiency and ability to reach all tooth surfaces is insufficient
Solution Approach 1:
The brush head is divided into multiple independent brush modules (first brush module, second brush module, third brush module, fourth brush module) that can rotate and move independently. Each module targets specific tooth surfaces, allowing simultaneous cleaning of multiple areas and dramatically improving cleaning efficiency while maintaining a relatively compact overall structure.
Solution Approach 2:
The patent employs dynamic brush modules that can rotate around tooth axes and move between different positions. The brush modules are designed to rotate in different directions (clockwise and counter-clockwise) to reach various tooth surfaces including occlusal surfaces, transforming a static brush head into a dynamic multi-functional cleaning system.
2Device complexity
If manual toothbrushing operation is required, then the toothbrush structure is simple, but the user must spend significant time and energy to ensure proper brushing of all tooth areas
Solution Approach 1:
The toothbrush performs self-service through automated rotation and positioning of brush modules. The motor-driven system automatically rotates brush modules around tooth axes and positions them to clean different tooth surfaces without requiring manual manipulation by the user, significantly reducing the time and effort needed for comprehensive tooth cleaning.
Solution Approach 2:
The brush modules execute periodic rotation cycles, alternating between clockwise and counter-clockwise directions to systematically clean different tooth surfaces. This periodic action ensures thorough coverage of all tooth areas including occlusal surfaces, reducing the total brushing time required while maintaining cleaning effectiveness.
3Ease of manufacture
If traditional brush head shapes are used, then the manufacturing is simple, but the brush head cannot ensure coverage of all tooth surfaces including occlusal surfaces and gaps between teeth
Solution Approach 1:
The brush head is designed as a universal cleaning system with multiple brush modules that can adapt to clean various tooth surfaces including outer surfaces, inner surfaces, and occlusal surfaces. The multi-functional design allows a single brush head to perform the work of multiple specialized brushes, ensuring complete coverage of all tooth areas.
Solution Approach 2:
The patent adds rotational movement as a new dimension to traditional linear brushing motion. Brush modules rotate around tooth axes in addition to moving along the tooth surface, creating three-dimensional cleaning coverage that reaches occlusal surfaces and gaps between teeth that conventional two-dimensional brushing cannot access.

AI summary
Provided is an omnidirectional scientific toothbrush comprising a brush handle (2) and a brush head (3), wherein the brush head (3) has a U-shaped structure; a central gear set (309), a tooth outer side brush roller (302), a tooth inner side brush roller (307) and a tooth end surface brush roller (303) are installed in the brush head (3); the brush handle (2) is provided with a power output mechanism driven by a micro motor (218), wherein the power output mechanism drives the central gear set (309) to rotate, so that the tooth outer side brush roller (302) and the tooth inner side brush roller (307) at both sides of the same tooth are rotated in an opposite direction and both rotation directions are from the tooth root to the tooth end, and the rotational action of the tooth end surface brush roller (303) can simultaneously scrub end surfaces of the upper and lower rows of teeth (6, 7) in the oral cavity along the tooth gap. When brushing the teeth, there is no need for the user to manually control the brush head (3) of the toothbrush to move, that is, a tooth full-mouth cleaning operation can be automatically completed, thereby greatly improving the quality and efficiency of brush cleaning, greatly reducing the time cost and energy consumption of brushing, and easily achieving an intelligent and automatic brushing mode.
