Toothbrush Handle With Integrated Pump And Vibration Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing toothbrush devices with integrated toothpaste reservoirs lack efficient toothpaste dispensing and vibration functionality for enhanced brushing experience.
Innovation Solution
A toothbrush device with a hollow handle containing a toothpaste-filled cylinder and a pump for dispensing toothpaste, combined with a vibration unit for improved brushing, where the toothbrush head is removably attachable and receives toothpaste for deposition on teeth, and a vibration unit is integrated to enhance brushing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pump is integrated into the handle to dispense toothpaste, then toothpaste dispensing efficiency is improved, but device complexity increases
Solution Approach 1:
The pump mechanism is nested within the hollow handle structure, with the cylinder containing toothpaste positioned inside the handle and the pump mechanism integrated within the same space. This nesting approach allows the dispensing function to be added without proportionally increasing the external dimensions or overall complexity of the device.
Solution Approach 2:
The handle serves multiple functions: it contains the toothpaste cylinder, houses the pump mechanism for dispensing, and provides structural support for the vibration unit. By making the handle multi-functional, the patent reduces the need for separate components, thereby improving dispensing efficiency while limiting the increase in overall device complexity.
2Productivity
If a vibration unit is integrated into the handle, then brushing efficacy is improved, but device complexity increases
Solution Approach 1:
The vibration unit is merged with the handle structure, where the motor and vibration mechanism are integrated within the handle's internal space. This combination allows the toothbrush head to receive vibrational motion for enhanced brushing efficacy while avoiding the need for a separate vibration device, thus limiting the increase in device complexity.
Solution Approach 2:
The handle is designed as a multi-functional component that simultaneously provides structural support, houses the toothpaste dispensing system, and incorporates the vibration unit. This multi-functionality approach allows brushing efficacy to be improved through vibration while keeping the overall device complexity controlled by reusing the handle structure.
3Ease of operation
If the toothbrush head is removably attachable, then ease of operation is improved, but reliability decreases
Solution Approach 1:
The toothbrush is divided into separable components: a removable toothbrush head and a handle containing the dispensing and vibration mechanisms. This segmentation allows the head to be easily attached and detached for cleaning or replacement, improving ease of operation. The patent addresses the reliability concern by designing appropriate connection interfaces that maintain secure attachment during use.
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 device efficiently dispenses toothpaste and vibrates the toothbrush head for improved brushing efficacy, providing a convenient and effective oral hygiene solution.
Implementation Method 1
A pump is positioned within the handle to pump the toothpaste outwardly from the cylinder when the pump is turned on
Implementation Method 2
A vibration unit is integrated into the handle and the vibration unit vibrates the toothbrush head when the vibration unit is turned on

AI summary
A toothpaste dispensing toothbrush assembly for brushing teeth includes a handle that has an open end for accessing an interior of the handle. A cylinder is filled with a toothpaste and the cylinder is insertable into the open end of the handle. A pump is positioned within the handle to pump the toothpaste outwardly from the cylinder when the pump is turned on. A toothbrush head is removably attachable to the handle to brush the user's teeth. The toothbrush head receives the toothpaste from the pump to deposit the toothpaste on the user's teeth. A vibration unit is integrated into the handle and the vibration unit vibrates the toothbrush head when the vibration unit is turned on.
