Low Viscosity Foamable Dental Care Composition for Simultaneous Tooth Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental care products, such as pastes and gels, are unsuitable for use with tooth cleaning devices that clean multiple teeth simultaneously, as they are too viscous, leading to uneven distribution and excessive waste, and known foams are too stable, causing loss of active substances and interference with motor vibrations.
Innovation Solution
A foamable dental care composition with a low viscosity, containing glycerol, precipitated silicates, and surface-active substances, which expands to form a stable foam on the mouthpiece and quickly breaks down during use, ensuring even distribution and effective cleaning of all teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional dental care products (pastes or gels) are used, then they provide cleaning function, but their high viscosity (60,000 to 70,000 mPas) causes uneven distribution on mouthpiece and excessive waste
Solution Approach 1:
The patent changes the viscosity parameter of the dental care composition from conventional high viscosity (60,000-70,000 mPas) to low viscosity (100-10,000 mPas, preferably 500-5,000 mPas). This parameter change enables even distribution on the mouthpiece while reducing waste, directly resolving the contradiction between distribution precision and ease of application.
2Reliability
If known foams are used, then they provide cleaning function, but their high stability causes loss of active substances and interference with motor vibrations
Solution Approach 1:
The patent applies a dynamic approach to foam stability by using surfactants that provide temporary stability during application and storage on the mouthpiece, but allow the foam to break down during the cleaning process. This dynamic behavior ensures active substances are not lost and motor vibrations are not interfered with, while maintaining reliability during the critical application phase.
Solution Approach 2:
The foam exhibits periodic behavior: stable during application and storage, then breaking down during use. This periodic change in stability allows the foam to serve different functions at different times - maintaining structure when needed and dissipating when needed - resolving the contradiction between reliability and harmful effects.
3Manufacturing precision
If low viscosity composition is used, then even distribution is achieved, but adhesion to mouthpiece may be insufficient
Solution Approach 1:
The patent uses surfactants to modify the surface tension and adhesion parameters of the low viscosity composition. The surfactants enable the composition to adhere sufficiently to the mouthpiece despite its low viscosity, while still allowing for even distribution. This resolves the contradiction by changing the surface properties rather than increasing viscosity.
