Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toothpaste tubes are cumbersome, prone to leakage or drying out, and lack precise fluoride delivery, leading to potential overuse and increased risk of enamel fluorosis, especially in children.
Innovation Solution
Development of rapidly dissolving oral films or strips containing a water-soluble polymer and precise dosages of fluoride, designed for easy application and minimal moisture loss, with optional additives for enhanced cleaning and spitting promotion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional toothpaste tubes are used, then fluoride delivery is provided, but the tubes are heavy, prone to leakage or drying out, and lack precise fluoride delivery
Solution Approach 1:
The toothpaste is segmented into a thin film format that can be precisely measured and applied, replacing the bulky tube structure. This segmentation allows for precise fluoride delivery while eliminating the leakage and drying out issues of conventional tubes.
Solution Approach 2:
The invention uses a thin film as the delivery vehicle for toothpaste, replacing the rigid tube structure. This thin film approach provides precise fluoride delivery, is lightweight, and eliminates the problems of leakage and drying out associated with conventional tubes.
2Reliability
If fluoride-containing toothpaste is used, then dental caries prevention is achieved, but overuse leads to enamel fluorosis especially in children
Solution Approach 1:
The invention replaces the mechanical tube-based application system with a thin film system that allows for precise control of fluoride delivery. This substitution enables accurate dosing that prevents both inadequate caries prevention and excessive fluoride intake leading to fluorosis.
Solution Approach 2:
The invention changes the delivery parameters by using thin films with controlled thickness and surface area, allowing precise control of the amount of fluoride delivered. This parameter control ensures adequate caries prevention while preventing overuse and enamel fluorosis in children.
3Ease of operation
If standard toothpaste tubes are used, then cleaning function is provided, but they are cumbersome and difficult to use
Solution Approach 1:
The invention replaces the heavy tube structure with a lightweight thin film that is easy to handle and apply. This thin film approach eliminates the cumbersome nature of conventional tubes while maintaining the cleaning function through precise fluoride and abrasive delivery.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides a convenient, non-adhering, and accurately dosed fluoride delivery system that mitigates overuse risks and facilitates safe fluoride intake, particularly for children, while maintaining effective dental cleaning and fluoridation.
Implementation Method 1
The mono- or multi-layer films contain a water soluble polymer. The films also contain a dentifrice ingredient that is distributed throughout one or more layers of the film.
