Dental Suction Tip with Vent Shells and Silicone Nozzle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-volume dental suction tips are prone to clogging and cause discomfort due to their design, leading to ineffective suction and potential trauma to patients, as they often have limited or no apertures, which results in decreased suction force and increased risk of aspiration.
Innovation Solution
A high-volume dental suction tip with a cylindrical body perforated by multiple apertures covered by vent shells, featuring a soft silicone rubber nozzle with vertical milling cutters, designed to enhance suction force and prevent clogging, while minimizing trauma to soft tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple apertures are added to the suction tip, then suction force and mass flow are improved, but the tip becomes more prone to clogging
Solution Approach 1:
The patent applies flexible shells (venting membranes) covering the apertures to prevent clogging while maintaining suction efficiency. These flexible membranes allow fluid passage but block debris, resolving the contradiction between needing multiple apertures for high suction force and preventing clogging through the selective filtering action of the flexible shell material.
2Strength
If a hard plastic tip is used, then structural strength is improved, but trauma to soft tissue increases
Solution Approach 1:
The patent applies local quality by using different materials in different regions of the tip. The main body retains hard plastic for structural strength, while the distal end contacting soft tissue is made of soft silicone rubber to minimize trauma. This regional differentiation allows the tip to simultaneously achieve structural integrity and patient comfort.
Solution Approach 2:
The patent employs composite materials by combining hard plastic for the main body with soft silicone rubber for the distal end. This composite construction allows the tip to leverage the strength of rigid materials while using compliant materials where patient comfort is critical, effectively resolving the contradiction between structural strength and tissue trauma prevention.
3Reliability
If limited apertures are used, then clogging is reduced, but suction efficiency and mass flow decrease
Solution Approach 1:
The flexible shell material allows the tip to maintain reliability by preventing clogging while preserving productivity. The membrane structure provides sufficient open area for high mass flow and suction efficiency while the flexible nature blocks debris, simultaneously achieving both clogging resistance and suction performance.
Applied Scientific Principles

AI summary
The embodiment provides a high-volume evacuation tip perforated with round shape apertures covered by vent shells with upgraded capability of capturing escaping saliva and surgical debris during dental operation, as well as its total mass flow capability with soft silicon rubber nozzle. The high-volume suction tip for dental procedures has a cylinder or tubular-shaped, having two open ends. Forward-facing end has a soft silicone rubber nozzle is round in shape reducing patient pain and discomfort due to contact of hard plastic suction with soft tissue of patient with several vertical milling cutters to improve maximum effectiveness of fluid absorption, preventing clogging a surgical aspirator and prevent traumatic absorption of the patient tongue. Posterior end has vertical cutting shape. The suction tip has increase impact force compare to similar suction tips without the plurality of apertures or with few of them.
