Dental Implant Bur Retaining Ring for Secure Depth Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implantology surgical burs with stop elements face issues such as deformed teeth affecting engagement, complex production processes, high costs due to color coding, and risk of detachment during drilling, leading to potential loss and increased production costs.
Innovation Solution
A new bur design with a retaining component, such as a titanium ring or elastic elements, replaces teeth for engaging the stop element, allowing greater tolerances and easier production, reducing friction and detachment risk, and enabling color coding without additional resin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stop element is held in the retaining groove during storage and transport, then the system remains compact and organized, but the stop element cannot be easily removed and installed by the user
Solution Approach 1:
The stop element is pre-loaded into the retaining groove during device assembly, but the groove is designed with a retention mechanism that maintains the stop element in place during storage and transport. The user can easily remove and reinstall the stop element when needed, combining secure retention with ease of operation.
2Productivity
If the bur rotates at high speed during operation, then drilling efficiency is improved, but the risk of accidental rotation and injury increases
Solution Approach 1:
The safety cap with the stop element is placed over the bur before operation. The stop element protrudes into the path of the bur rotation, creating a physical barrier that prevents the bur from rotating accidentally. This preliminary protective measure allows high-speed operation when needed while preventing accidental rotation during storage and transport.
Solution Approach 2:
The stop element acts as an intermediary between the user's finger and the rotating bur. It provides a safe contact point that allows the user to hold and control the bur without direct contact with the hazardous rotating surface, thereby enabling high-speed operation while minimizing injury risk.
3Ease of manufacture
If the safety cap design is simple with minimal components, then manufacturing cost is reduced, but the locking mechanism may not provide sufficient security
Solution Approach 1:
The safety cap is divided into distinct functional components: the cap body, the stop element, and the retaining groove. This segmentation allows each component to be manufactured independently using simple processes, while the combination of these components creates a reliable locking mechanism that secures the stop element in place.
