Multi-Bend Oral Irrigator Nozzle for Deep Tooth Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral irrigators with standard hot-bent nozzles struggle to effectively clean deep areas of the oral cavity, such as gaps between teeth, requiring users to open their mouths wide and risking damage to lips and teeth.
Innovation Solution
A nozzle design with a squirting tube featuring multiple bending sections, including a first bending section closer to the lips and a second bending section deeper into the oral cavity, allowing for a larger cleaning area without contacting the lips and teeth, and a fluid flow path that slows down to reduce impact force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a standard hot-bent nozzle is used, then the structure is simple and easy to manufacture, but it cannot effectively clean teeth deep in the oral cavity
Solution Approach 1:
The nozzle is divided into multiple bending sections (first bending section, second bending section, third bending section) with different extension directions. Each section can independently adapt to different anatomical structures in the oral cavity, enabling the nozzle to reach deep areas between teeth while maintaining manufacturing feasibility through modular design
Solution Approach 2:
The nozzle incorporates multiple bending sections that can dynamically adjust their positions and angles during use. The first bending section bends toward the second side of the first central axis, creating a first space that allows the nozzle to adapt to different oral cavity depths and angles, transforming a static structure into a dynamically adaptable one
2Productivity
If the nozzle is inserted deep into the oral cavity to clean teeth, then cleaning effectiveness improves, but the nozzle may contact and damage lips and teeth at the front of the oral cavity
Solution Approach 1:
The first bending section is designed to bend toward the second side of the first central axis, dynamically creating a first space that prevents the nozzle from contacting lips and teeth at the front of the oral cavity during deep insertion, thereby eliminating the harmful contact while maintaining cleaning effectiveness
Solution Approach 2:
The first bending section acts as an intermediary element between the main flow section and the deeper second bending section. It creates a protective first space that mediates the interaction between the nozzle and the oral cavity structures, preventing direct contact and potential damage
3Adaptability or versatility
If a user opens his/her mouth wide to clean deep teeth, then the nozzle can reach deeper areas, but user comfort decreases and the risk of damage increases
Solution Approach 1:
The multiple bending sections provide dynamic adaptability that allows the nozzle to reach deep oral cavity areas without requiring the user to open their mouth wide. The bending sections automatically adjust to navigate around anatomical obstacles, improving ease of operation while maintaining adaptability
Solution Approach 2:
By segmenting the nozzle into multiple independently positioned bending sections, the design enables gradual navigation into deep oral areas without requiring extreme mouth opening. Each section can be positioned optimally, making the cleaning process more comfortable and easier to operate

AI summary
A nozzle and an oral irrigator include a squirting tube. The squirting tube includes an inlet, an outlet, and a flow channel. The squirting tube includes a first bending position located between a first bending section, and a second bending section and a second bending position disposed between the second bending position and the outlet. An extension direction of the first bending section is different from an extension direction of the main flow section and an extension direction of the second bending section. The flow channel in the main flow section defines a first central axis. The outlet is located on a first side of the first central axis. The first bending section bends and extends from the main flow section to a second side, opposite to the first side, of the first central axis.
