Movable Coupling Device for Dental Handpiece Internal Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental flushing devices require multiple coupling parts with different insertion openings, leading to complex handling and a risk of improper internal cleaning due to varying geometric configurations of items to be cleaned, and they often create a 'washing shadow' that hinders external cleaning, particularly in handle areas.
Innovation Solution
A device with a movable coupling device and a clamping mechanism that automatically fixes items in position using a bow spring and compression spring, allowing universal use regardless of item geometry and minimizing the contact area for improved external cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple coupling parts with different insertion openings are used to accommodate different geometric configurations of items to be cleaned, then the adaptability is improved, but the device complexity and handling complexity increase
Solution Approach 1:
The patent implements a single universal coupling part design that can accommodate multiple different geometric configurations of items to be cleaned. Instead of requiring different coupling parts for different item geometries, this universal coupling part works with all item types, thereby reducing device complexity while maintaining adaptability.
Solution Approach 2:
The coupling part incorporates a movable clamping device that can dynamically adjust its position and clamping force to adapt to different item geometries. This dynamic adjustment capability allows the same coupling part to securely hold various item shapes without requiring multiple specialized coupling parts.
2Reliability
If a coupling part seals against the outside of items to be cleaned, then the liquid-tight connection is improved, but the external cleaning capability deteriorates due to washing shadow
Solution Approach 1:
The coupling device is segmented into distinct functional components: a coupling part for fluid connection and a separate clamping device for securing items. This segmentation allows the coupling part to provide liquid-tight sealing while the clamping device can be positioned to minimize interference with external cleaning processes, reducing the washing shadow effect.
Solution Approach 2:
The clamping device acts as an intermediary element between the coupling part and the item being cleaned. It provides the necessary mechanical clamping force while allowing the coupling part to maintain its sealing function, and its design minimizes the shadow effect on external cleaning by being positioned and shaped to allow cleaning fluid access.

Implementation Method 1
the coupling device is supported in relation to the connecting piece or in relation to a holding element connected to the connecting piece with the interposition of a compression spring
Implementation Method 2
the clamping device is designed as a bow spring, the spring legs of which each have a clamping jaw interacting with the items to be washed at one end

AI summary
The invention relates to a device for internally rinsing dental items, in particular turbines as well as handpieces and contra-angle handpieces, with a coupling device (9) for connecting the item (26) to a connecting nozzle (7) that is connected to or connectable to a connecting device (5) of a pipeline (4). In order to further develop a device of the type mentioned above in such a way as to achieve an improved cleaning result while simultaneously simplifying handling, the invention proposes that a clamping device (10) be provided for fixing the position of an item (26) connected to the coupling device (9), wherein the coupling device (9) is designed to be movable relative to the connecting nozzle (7) for actuating the clamping device (10).
