Mouthpiece Teeth Cleaner Using Segmented Bristle Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teeth-cleaning methods and devices, including customized toothbrushes like Blizzident, fail to effectively implement the Bass method due to their inability to fit the natural arched curve of the gingival sulcus and gingival margin, leading to incomplete cleaning.
Innovation Solution
A mouthpiece-type teeth-cleaning method that uses alternating excitation signals to generate specific cleaning operations tailored to each tooth position, with a digital three-dimensional tooth model and mouthpiece model correlation, allowing for personalized and efficient cleaning of hard-to-reach areas like the gingival sulcus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single movement direction is used for toothbrushing, then the device structure is simple, but the natural arched curve of the gingival margin cannot be fitted
Solution Approach 1:
The cleaning device is divided into multiple independent bristle groups, each capable of performing cleaning actions in different directions. This segmentation allows each bristle group to independently adapt to the arched curve of the gingival margin, resolving the contradiction between operational effectiveness and structural simplicity.
Solution Approach 2:
The bristle groups are designed with dynamic cleaning capabilities, where each group can perform cleaning actions in different directions based on the local anatomy of the tooth and gingival margin. This dynamic approach enables the device to fit the natural arch curve without requiring complex overall device structure.
2Productivity
If customized toothbrushes are used with 400+ soft bristles, then more tooth surfaces can be cleaned, but the brushing action still cannot fit the natural arch curve of the gingival sulcus
Solution Approach 1:
The bristle array is segmented into multiple groups with different orientations and cleaning capabilities. This segmentation enables each bristle group to target specific areas (tooth surfaces, gingival sulcus, interdental spaces) and perform appropriate cleaning actions, achieving both comprehensive coverage and Bass method effectiveness.
Solution Approach 2:
Different bristle groups are designed with different properties and cleaning actions tailored to their specific locations. Some bristle groups are optimized for tooth surface cleaning, others for gingival sulcus cleaning, and others for interdental space cleaning. This local quality differentiation enables the device to effectively implement the Bass method across all critical areas.
3Ease of operation
If traditional Bass method is applied manually, then cleaning effectiveness is achieved, but extensive movement and precise positioning are required
Solution Approach 1:
The cleaning device is designed to automatically perform cleaning actions without requiring extensive manual movement or precise positioning by the user. The device structure enables self-aligning and self-positioning functionality, where the bristle groups automatically adapt to the tooth anatomy and perform Bass method cleaning actions through the device's inherent design rather than complex user manipulation.

AI summary
A mouthpiece-type teeth cleaner, comprising: an excitation source, configured to generate one or more groups of alternating excitation signals; and a cleaning system, configured to generate one or more cleaning operations according to the excitation signals, with different cleaning actions applied to various parts of the teeth; wherein the teeth cleaner has a correlation between the cleaning operation and the cleaning action and each part of the tooth, and the correlation enables each part of the tooth to be individually cleaned.
