Toothbrush Suction Head Layout for Aspiration-Safe Brushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toothbrushes lack reliable mechanisms to collect toothpaste, saliva, and other debris during brushing, posing a risk of swallowing or aspiration, particularly for young, convalescent, elderly, or disabled individuals, leading to dental issues and respiratory diseases.
Innovation Solution
A suction apparatus for a toothbrush comprising a housing with a vacuum pump, collection reservoir, and conduits that apply suction around the toothbrush head to deposit materials in a collection reservoir, optionally with a foam to break surface tension and a one-way valve to prevent backflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction apparatus is added to the toothbrush, then the ability to collect and remove fluids and debris is improved, but the device complexity increases
Solution Approach 1:
The suction apparatus is integrated with the toothbrush by coupling the housing to the toothbrush head, merging the suction function with the existing toothbrush structure. This combination allows the toothbrush to perform both brushing and suction functions simultaneously, improving fluid collection reliability while minimizing the increase in device complexity through unified design.
Solution Approach 2:
The toothbrush is designed with multi-functionality by incorporating a suction apparatus that can collect fluids and debris during brushing. The same device performs both traditional brushing and suction operations, making it a universal tool that addresses multiple oral hygiene needs without requiring separate devices.
2Productivity
If a vacuum pump and collection reservoir are incorporated into the toothbrush, then the productivity of fluid removal is improved, but the weight of the device increases
Solution Approach 1:
The suction apparatus is designed as a separate housing that couples to the toothbrush head, segmenting the suction components from the main toothbrush handle. This segmentation allows the heavy components (vacuum pump and collection reservoir) to be positioned separately, improving fluid removal efficiency while managing the weight distribution to maintain portability and ease of use.
3Productivity
If the suction head portion is positioned close to the toothbrush head, then the suction effectiveness is improved, but the risk of interfering with brushing action increases
Solution Approach 1:
The suction head portion is positioned to create a gap around the toothbrush head, providing localized suction effectiveness at the periphery where fluids and debris accumulate. This local positioning allows the suction to target specific areas without interfering with the central brushing action, maintaining ease of operation while improving suction productivity through strategic placement.
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
Effectively removes liquids and debris during brushing, reducing the risk of aspiration and bacterial growth, thereby preventing respiratory diseases and dental caries.
Implementation Method 1
The suction apparatus further includes a vacuum pump, a collection reservoir, and one or more conduits that couple the vacuum pump, suction head portion, and collection reservoir to apply a suction around the toothbrush head through the gap and deposit suctioned material in the collection reservoir.
Implementation Method 2
a foam or other porous material disposed at least partially in the gap between the suction head portion and the toothbrush head

AI summary
A suction assembly, toothbrush, and method are provided that suction fluids and debris resulting from brushing. The suction assembly includes a housing configured to couple to the toothbrush so that a portion extends around sides and a back of the toothbrush head and is spaced from the toothbrush head by a gap. The suction assembly further includes a vacuum pump, a collection reservoir, and one or more conduits that couple the vacuum pump, suction head portion, and collection reservoir to apply a suction around the toothbrush head through the gap and deposit suctioned material in the collection reservoir.
