Sonic Tool Rounded Peripheral Wall Membrane Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound-driven dental tools face challenges in safely and efficiently detaching the Schneiderian membrane from bone tissue during implantation site preparation, often risking membrane tear or difficult detachment due to tool shape and structure.
Innovation Solution
A sound-driven dental tool with a blunt and rounded peripheral wall and end face, equipped with multiple openings for liquid dispensing, allows for mechanical detachment by direct contact and vibration-assisted liquid film generation, reducing the risk of membrane damage and facilitating easier separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a sharp or pointed working section is used for membrane detachment, then the detachment efficiency is improved, but the risk of membrane tearing increases
Solution Approach 1:
The working section is designed with a rounded outer periphery instead of sharp edges, creating a blunt tip geometry that mechanically detaches the membrane from bone tissue without concentrating stress that would cause tearing. The curved surface distributes contact forces evenly across the membrane tissue.
Solution Approach 2:
The tool utilizes ultrasonic vibrations at the working section to facilitate membrane detachment. The vibratory motion enhances the separation process by creating micro-movements that help detach the membrane from the bone surface without requiring excessive mechanical force that could tear the membrane.
2Productivity
If liquid is dispensed at high pressure for membrane detachment, then the detachment speed is improved, but the risk of membrane rupture increases
Solution Approach 1:
Multiple liquid discharge openings are distributed across the working section surface, allowing liquid to be delivered at lower pressure from multiple locations simultaneously. This distributed delivery system achieves effective membrane detachment without the high localized pressure that would cause rupture.
Solution Approach 2:
The liquid acts as an intermediary substance between the tool and the membrane, facilitating detachment through hydration and pressure distribution rather than direct mechanical contact. The liquid film allows the blunt working section to slide along the membrane without direct abrasive contact.
3Reliability
If the working section has a large contact area with the membrane, then the detachment safety is improved, but the tool complexity increases
Solution Approach 1:
The working section incorporates multiple discrete liquid discharge openings distributed across its surface, segmenting the liquid delivery function. This segmentation allows for effective membrane contact over a larger area while maintaining a relatively simple overall tool structure with standardized components.
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 tool significantly reduces the risk of membrane tearing and enhances the ease and safety of detachment, ensuring a reliable and efficient separation process for preparing implantation sites.
Implementation Method 1
a sound source (3) for vibrating the working section (4) at sound frequencies, in particular at ultrasonic frequencies
Implementation Method 2
a liquid film can be generated which ensures safe sliding of the end face on the membrane
Implementation Method 3
the detachment of the membrane from the bone tissue cannot be brought about, or not only by the liquid dispensed, but (also) by direct contact of the working section of the tool, in particular the peripheral wall with the blunt and rounded outer circumference, with the membrane and/or with the bone tissue

AI summary
The tool (1) has a connector (2) which is connected with a work portion (4) through shaft (5). A liquid conduit is extended to working portion through shaft. An end face of working portion is connected to circumferential wall (8). The outer diameter of end face is larger than outer diameter of shaft. The end face formed opening (9), is connected to a liquid conduit, so that the liquid conduit leaks liquid from the opening. The circumferential wall is formed with a rounded outer periphery, so as to mechanically separate the two different tissues from each other. Independent claims are included for the following: (1) a method for producing sonically drivable tool; and (2) a method for separating two different fabric.
