Oral Cavity Cleaner With Separate Washing-Water And Suction Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral cavity cleaners struggle to effectively manage cleanliness regardless of the arrangement of teeth, particularly for irregularly arranged teeth, as they fail to simultaneously facilitate the flow of washing water and contaminated water, leading to incomplete plaque removal and tartar formation.
Innovation Solution
An oral cavity cleaner with a mouthpiece that sprays washing water, a core suction part that sucks contaminated water, and a handle with specific flow paths and guides to ensure simultaneous and smooth flow of washing and contaminated water, including diffusion and discharge paths, and a suction pipe to connect these components, ensuring thorough cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If washing water is sprayed into the oral cavity and contaminated water is suctioned simultaneously, then cleaning effectiveness is improved, but water flow management becomes complex and difficult to control
Solution Approach 1:
The handle is divided into multiple independent flow paths: a washing water flow path for supplying washing water to the mouthpiece, and a suctioned water flow path for discharging contaminated water. These separate pathways prevent interference between the two water flows while maintaining simultaneous operation capability.
Solution Approach 2:
A flow guide is introduced as an intermediary component within the handle to direct and separate the washing water flow from the suctioned water flow. This mediator ensures that the two water streams do not mix or interfere with each other, enabling smooth simultaneous flow of both waters.
2Ease of operation
If the flow paths for washing water and contaminated water are separate, then water flow control is improved, but the device structure becomes more complex
Solution Approach 1:
The handle integrates both the washing water flow path and the suctioned water flow path into a single handle body structure. While the flow paths are functionally separate, they are spatially combined within the handle, avoiding the need for separate devices and reducing overall structural complexity.
Solution Approach 2:
The flow paths are arranged in different spatial dimensions and orientations within the handle. The washing water flow path and suctioned water flow path are positioned separately in three-dimensional space, allowing independent control while maintaining a compact integrated structure.
3Productivity
If washing water flows smoothly to the mouthpiece, then cleaning performance is improved, but preventing mixing with contaminated water becomes difficult
Solution Approach 1:
The suction pipe is extracted and positioned separately from the washing water flow path. It extends from the mouthpiece into the oral cavity to directly suction contaminated water at the source, preventing it from mixing with the washing water that flows through the handle to the mouthpiece.
Solution Approach 2:
The flow guide acts as an intermediary barrier and director within the handle, separating the washing water flow from the suctioned water flow. It ensures that washing water flows smoothly to the mouthpiece while preventing contaminated water from entering the washing water pathway.
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 design allows for efficient cleaning by uniformly dispersing washing water and effectively removing contaminated water, reducing tartar formation and bacterial proliferation, thereby maintaining oral cavity cleanliness.
Implementation Method 1
a diffusion flow path configured to define a space in which the washing water flows in a direction toward at least one of upper and lower sides of the discharge flow path
Implementation Method 2
a core suction part configured to suck contaminated water, in which the washing water and saliva are mixed, from the inside of the oral cavity

AI summary
An oral cavity cleaner includes a mouthpiece that sprays washing water into the oral cavity, a core suction part that suctions contaminated water formed by mixing the washing water and saliva inside the oral cavity, and a handle having an inflow path for introducing the washing water, a discharge flow path for removing the contaminated water, and a diffusion flow path that defines a space through which the washing water is directed toward at least one of the upper or lower sides of the discharge flow path and is delivered to the mouthpiece.
