Replaceable Interproximal Brush Head with Fluid Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional squirt brushes are disposable due to a non-replaceable brush head, limiting their reuse and increasing material waste, while they struggle to effectively clean interproximal areas between teeth and gums, leading to discomfort and inefficiency in plaque removal.
Innovation Solution
A design where the brush head is replaceably coupled with a solution container, allowing for refilling and easy replacement, featuring a clearance for solution discharge and a simple clip operation, enabling the use of different brush heads and minimizing material waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the brush head is fixed to the solution container, then the squirt brush can be manufactured simply, but the brush head cannot be replaced and must be disposed after use
Solution Approach 1:
The squirt brush is divided into separate components: a reusable solution container and a replaceable brush head. The brush head can be detached and replaced by twisting it off and on the container neck, allowing the container to be reused with different brush heads for various cleaning needs while maintaining manufacturing simplicity.
2Productivity
If the brush head is small enough to fit between teeth, then interproximal cleaning effectiveness is improved, but the brush head cannot be effectively reused
Solution Approach 1:
By separating the brush head from the solution container, the small brush head can be reused multiple times by replacing it on the same container. The container serves as a durable base that can hold different brush heads, extending the overall service life while maintaining the small size needed for effective interproximal cleaning.
Solution Approach 2:
The solution container is designed as a universal base that can accommodate multiple different brush heads. This allows a single container to serve multiple cleaning purposes by simply changing the brush head, extending the duration of use and reducing waste.
3Ease of manufacture
If the squirt brush is designed as disposable, then manufacturing and disposal are simple, but material waste increases
Solution Approach 1:
The squirt brush is segmented into a reusable solution container and a replaceable brush head. The container can be refilled and reused multiple times, while only the brush head is disposed of after use. This significantly reduces material waste compared to completely disposable designs, while maintaining simple manufacturing processes for each component.
4Productivity
If conventional flossing technique is used, then plaque removal is achieved, but the operation process is cumbersome and time-consuming
Solution Approach 1:
The invention merges the functions of flossing and brushing into a single tool. The brush head is positioned to reach between teeth and along the gum line, while the solution container delivers cleaning solution directly to the brush head. This combination allows users to achieve both interproximal cleaning and gum line brushing in one simple operation, eliminating the need for separate flossing steps.
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 solution extends the life span of the squirt brush, reduces material waste, and provides effective cleaning of interproximal areas by allowing for the use of various brush heads and easy refilling, enhancing user comfort and efficiency in plaque removal.
Implementation Method 1
a hollow nozzle head (12) having an opening (121) communicating with the solution chamber (11)
Implementation Method 2
wherein when the solution supplier (14) is actuated, such as operated by a pump device to controllably pump the solution to the nozzle head (12)
Implementation Method 3
when the solution supplier (14) is actuated, such as operated by a pump device to controllably pump the solution to the nozzle head (12) through the solution delivering tube (15)
Implementation Method 4
Due to the friction between the brush head and the gum line, tenderness during dry brushing always gives discomfort to the user

AI summary
An interproximal squirt brush, includes a solution container having a solution chamber for containing a solution and a hollow nozzle head having an opening communicating with the solution chamber; and a brush head having an elongated retention portion replaceably coupling at the opening of the nozzle head and a brush portion extended from the retention portion, wherein a clearance is formed between the opening and the retention portion of the brush head for enabling the solution from the solution chamber being discharged to the brush portion of the brush head along the retention portion.
