UV Toothbrush Cap Microbe Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for sanitizing toothbrush bristles, such as using caps, are ineffective in eliminating microbes, leading to potential hygiene issues, especially during travel when toothbrushes are exposed to contaminated surfaces.
Innovation Solution
An ultraviolet light-based apparatus is integrated into a toothbrush design that includes a cap to kill microbes on the bristles, activated when the cap is closed over the bristles, ensuring effective sanitization regardless of the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a cap is used to cover the bristles, then the bristles are protected from external contamination, but microbes already on the bristles are not eliminated
Solution Approach 1:
The patent replaces the passive mechanical protection system (cap) with an active optical/energy-based system (ultraviolet light source) that can actually eliminate microbes through photodissociation and photooxidation processes, rather than merely covering them
Solution Approach 2:
The patent introduces an intermediary substance (sanitizing agent such as hydrogen peroxide or bleach) that is activated by ultraviolet light to enhance the killing of microbes on the bristles, creating a more effective sanitization process
2Ease of manufacture
If rinsing with water is used to sanitize bristles, then some microbes are removed, but complete sanitization is not achieved
Solution Approach 1:
The patent changes the parameters of the sanitization process by introducing ultraviolet light wavelength and chemical concentration (sanitizing agent) to achieve complete microbe elimination, moving beyond simple water rinsing which operates at different energy and chemical parameters
Solution Approach 2:
The patent applies preliminary action by pre-treating the bristles with a sanitizing agent before activating the ultraviolet light source, which enhances the effectiveness of the subsequent light exposure in killing microbes
3Adaptability or versatility
If travel is involved, then exposure to contaminated surfaces increases, but current protection methods are insufficient
Solution Approach 1:
The patent replaces inadequate mechanical protection (caps) with an active energy-based sanitization system that can effectively eliminate microbes even in travel conditions where contamination risk is higher
Solution Approach 2:
The patent implements self-service by enabling the toothbrush to sanitize itself through an integrated ultraviolet light source that activates when the cap is removed or during storage, allowing the device to protect itself from microbial contamination during travel
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
The ultraviolet light effectively eliminates a majority of microbes from the toothbrush bristles, enhancing hygiene and reducing the risk of microbial transfer, making it suitable for both home and travel use.
Implementation Method 1
an ultraviolet light configured to eliminate bacteria from the bristles of a toothbrush
Implementation Method 2
at least one light attached to an interior of the apparatus and configured to kill microbes on a plurality of bristles
