Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric toothbrushes and tooth washers are independent devices that are inconvenient to operate, have limited cleaning effectiveness due to low vibration power, occupy large space, are difficult to carry, and have high manufacturing costs.
Innovation Solution
An integrated device for washing and brushing teeth that combines a toothbrush head, a shell, a water pump assembly, and an acoustic motor, featuring high-pressure water outlets on the bristle surface and high-frequency magnetic suspension motor for enhanced cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electric toothbrush and tooth washer are used as independent products, then each device can perform its specific function, but the device complexity increases and occupies large space
Solution Approach 1:
The patent combines the toothbrush and tooth washer into a single integrated device. The toothbrush head contains both brushing bristles and water outlet holes, while the handle integrates the acoustic motor for vibration and the water pump assembly for high-pressure water delivery. This merging eliminates the need for separate devices, reducing space occupation and simplifying operation while maintaining both brushing and washing functions.
Solution Approach 2:
The integrated device performs multiple functions through a single system. The toothbrush head serves dual purposes: mechanical brushing via bristles and water irrigation via outlet holes. The control system allows switching between different modes (brushing only, washing only, or combined mode), providing universal functionality that adapts to different cleaning needs.
2Manufacturing precision
If electric toothbrush uses high-frequency vibration for cleaning, then cleaning effect is improved, but the vibration power remains small and cannot remove dirt deep between teeth
Solution Approach 1:
The patent introduces a water pump assembly that generates high-pressure water flow (90-180 PSI) to deliver water through the toothbrush head's outlet holes. This hydraulic component provides the additional power needed to penetrate and flush out deep interdental dirt and food residues, complementing the acoustic motor's vibration function and overcoming the limitation of insufficient vibration power alone.
3Area of stationary object
If multiple water outlets are arranged on the bristle surface, then the washing area is increased, but the device complexity increases
Solution Approach 1:
The toothbrush head is segmented into multiple functional zones with at least two water outlet holes positioned at different locations on the bristle surface. This segmentation allows water to be delivered to multiple areas simultaneously, expanding the washing coverage. The outlets are strategically placed to target different regions of the oral cavity, including interdental spaces and gum lines.
4Ease of operation
If integrated device combines toothbrush and tooth washer, then operation is simplified and space is reduced, but manufacturing cost increases
Solution Approach 1:
The patent specifies optimized parameter ranges for key components to balance performance and manufacturability. The water pressure is set at 90-180 PSI, and the acoustic motor operates at 32,000-50,000 Hz vibration frequency. These parameter specifications ensure effective cleaning performance while allowing for standardized production processes and component selection, helping to control manufacturing costs despite the integrated design.
