Oral Irrigator Nozzle Anti-Slip Limiting Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oral irrigators face challenges in maintaining stability and efficiency during tooth cleaning due to slipping issues caused by saliva and the smoothness of tooth surfaces, leading to ineffective cleaning of gaps between teeth and potential damage to gums or the oral cavity.
Innovation Solution
The design incorporates a spray head with a stopping structure featuring two limiting portions that abut against adjacent teeth, providing reverse support and preventing sliding, ensuring stable positioning and effective cleaning of tooth slits while minimizing risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the nozzle is made smooth for easy cleaning, then cleaning efficiency is improved, but the nozzle slips on tooth surfaces reducing stability
Solution Approach 1:
The nozzle is divided into distinct functional segments: a smooth spray head portion for efficient cleaning and a separate limiting portion with anti-slip texture for stable positioning. This segmentation allows each part to optimize its specific function without compromise.
Solution Approach 2:
Different portions of the nozzle are given different surface qualities: the spray head maintains smoothness for cleaning efficiency while the limiting portion incorporates textured, anti-slip surfaces for stability. This local differentiation resolves the contradiction between smoothness and grip.
2Productivity
If the nozzle is made larger to clean gaps between teeth, then cleaning effectiveness is improved, but the risk of sliding to gums increases
Solution Approach 1:
The limiting portion is designed to be deformable rather than rigid, allowing it to dynamically adapt to the tooth surface contour. This enables the larger nozzle to maintain stable contact without forcing, reducing the risk of sliding to gums during operation.
Solution Approach 2:
The material properties of the limiting portion are specifically adjusted to have appropriate elasticity and deformation characteristics. This parameter change allows the nozzle to conform to tooth surfaces while maintaining sufficient contact area to prevent sliding, even when the nozzle is enlarged for gap cleaning.
3Stability of the object's composition
If force is applied to prevent sliding, then stability is improved, but the risk of damaging gums increases
Solution Approach 1:
The deformable limiting portion acts as an intermediary between the nozzle and the tooth surface. It absorbs and distributes applied forces through controlled deformation, providing stability while preventing direct transmission of excessive forces to the gums.
Solution Approach 2:
The limiting portion is designed with inherent deformability that provides beforehand cushioning for any forces applied during operation. This pre-engineered deformation capability protects the gums from damage while maintaining nozzle stability, eliminating the need for excessive applied force.
