Intraoral Mouthpiece With Segmented Chambers for Suction Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental devices fail to consistently maintain a dry field of work during procedures due to suction loss from vacuum forces or pressure from the patient's tongue and palate, requiring frequent assistance and interrupting the procedure.
Innovation Solution
A dental mouthpiece with anterior and posterior flaps forming open evacuation chambers, featuring channels or nodules to ensure consistent communication and prevent collapse, connected to a suction source for continuous fluid removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional dental devices are used, then fluid evacuation can be achieved, but suction is lost due to collapse from vacuum forces or tongue pressure
Solution Approach 1:
The mouthpiece is divided into multiple flaps (anterior and posterior flaps) that form separate evacuation chambers. This segmentation allows each chamber to maintain its structure independently while collectively providing robust suction resistance against tongue pressure and vacuum forces.
Solution Approach 2:
The flaps are designed with varying thicknesses and structural characteristics in different regions. The anterior and posterior flaps have specific thickness profiles that provide localized structural support where needed, preventing collapse under specific pressure conditions while maintaining flexibility for proper sealing.
2Productivity
If conventional devices are used, then fluid removal can be performed, but the device requires frequent replacement or assistance
Solution Approach 1:
The mouthpiece is designed to maintain continuous suction and fluid evacuation throughout the entire dental procedure without requiring replacement or assistant intervention. The robust flap structure ensures uninterrupted operation from the beginning to the end of the procedure, eliminating idle time.
3Reliability
If conventional mouthpieces are used, then fluid evacuation is possible, but the field of work remains contaminated
Solution Approach 1:
The mouthpiece creates separate evacuation chambers isolated from the dental field of work. The anterior and posterior flaps form distinct chambers that capture fluids before they can contaminate the work area, providing reliable isolation while maintaining continuous suction.
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 mouthpiece maintains consistent suction without collapsing, ensuring a dry field for dental procedures by effectively evacuating fluids and providing patient comfort and safety.
Implementation Method 1
The mouthpiece is attached to a suction source that draws negative pressure into the mouthpiece
