Integrated Toothbrush with Effervescent Pellet Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toothbrushes require separate carrying of toothpaste, which is inconvenient for travel and use, as they necessitate multiple steps to apply and reassemble, often leading to forgetfulness or inconvenience.
Innovation Solution
A portable toothbrush design with removable caps and integrated toothpaste pellets that foam upon exposure to water or saliva, allowing for easy use without additional toothpaste tubes, featuring magnetic or threaded connections and one-way gates for controlled toothpaste delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If toothpaste is carried separately in a tube, then the toothbrush can be simple and compact, but the user must perform multiple steps to apply and reassemble toothpaste during travel
Solution Approach 1:
The patent combines the toothbrush and toothpaste into a single integrated device. The toothpaste is stored in a compartment within the toothbrush handle, and a applicator brush is included to transfer the toothpaste to the toothbrush bristles. This merging eliminates the need to separately carry and manually apply toothpaste, allowing users to simply attach the applicator brush to the toothbrush and proceed directly to brushing.
2Ease of operation
If toothpaste is carried separately, then the toothbrush remains simple and portable, but the user must remove and reassemble multiple components before and after brushing
Solution Approach 1:
The toothpaste is pre-loaded into the integrated compartment of the toothbrush during manufacturing. The applicator brush is pre-attached and ready for use. This preliminary preparation eliminates the need for users to perform multiple assembly and disassembly steps before and after brushing, saving time and effort during travel.
3Adaptability or versatility
If toothpaste is integrated into the toothbrush, then the device becomes self-contained and portable, but the toothbrush structure becomes more complex
Solution Approach 1:
The toothpaste compartment is nested within the handle structure of the toothbrush, utilizing existing internal space. The applicator brush is nested within a protective compartment that opens to allow access to the toothpaste. This nesting approach integrates the additional functionality into the existing toothbrush form factor without significantly increasing external dimensions or overall complexity.
4Ease of operation
If toothpaste is applied manually from a tube, then the toothbrush remains simple, but the user must perform multiple steps to apply and reassemble toothpaste
Solution Approach 1:
The patent extracts the toothpaste application function from the separate toothpaste tube and integrates it directly into the toothbrush. The applicator brush is removed from its separate packaging and incorporated as a permanent component of the toothbrush assembly. This extraction and integration eliminates the need to handle separate toothpaste tubes and caps, reducing the number of components the user must manage during travel.

Data Source
AI summary
A toothbrush having a handle portion, a shank portion and a head portion. A channel extends longitudinally through the handle portion, the shank portion and terminates in the head portion. The channel is sized to slidably receive one or more toothpaste pellet formulated to effervesce when exposed to water or saliva. An aperture extends transverse through the head portion providing fluid communication into the channel. A one-way gate is disposed within the channel permitting a toothpaste pellet to pass into the head portion, and to prevent the toothpaste pellet from passing out of the head portion. A handle cap is removably attached to a lower end of the handle portion. The head portion and shank portion may be received within a head cap that removably attaches to the handle portion.
