Grounded Dust Drawer for Dental Suction Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental laboratory suction devices lack in terms of comfort and operating safety, particularly in the design of dust collection systems, which often require complex components and pose risks due to static charges and potential electric shocks.
Innovation Solution
A suction device with a dust collection container integrated into the housing, designed as a dust drawer that is grounded during operation, made of electrically conductive plastic, and equipped with a locking ring element to prevent dust turbulence, ensuring easy emptying and reduced risk of electric shocks, while maintaining a compact and accessible design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dust collection container with cover is used, then dust is contained effectively, but emptying requires removing the cover which reduces operating comfort
Solution Approach 1:
The dust container is merged with the housing to form an integrated dust drawer that can be pulled out directly for emptying. The container and housing are combined into a single removable unit, eliminating the need for separate covers and simplifying the emptying process to a single action of pulling out the dust drawer.
2Reliability
If non-conductive plastic is used for dust container, then manufacturing is simpler, but static charges cause operating safety risks
Solution Approach 1:
The dust container is made from electrically conductive plastic, a composite material that combines the ease of plastic manufacturing with electrical conductivity. This conductive plastic allows the container to be grounded through the housing, dissipating static charges while maintaining the manufacturing advantages of plastic materials.
3Volume of moving object
If dust collection container is integrated into housing, then space efficiency improves, but accessibility for emptying may be reduced
Solution Approach 1:
The dust container is designed as a dynamic dust drawer that can be pulled out from the housing along a guide rail. This dynamic design allows the container to be integrated into the housing for space efficiency during operation, while providing easy accessibility when needed for emptying by simply pulling the drawer outward.
4Reliability
If multiple components are used for dust container, then sealing and safety are improved, but assembly complexity increases
Solution Approach 1:
The dust collection system is segmented into functional zones within the integrated dust drawer: a dust receiving area with vortex-blocking elements to prevent turbulence, a guide rail system for smooth extraction, and grounding contacts for safety. This segmentation of functions within a single integrated component achieves reliable sealing and safety without increasing assembly complexity.

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 solution enhances operating comfort by allowing easy disposal of filtered dust, reduces the risk of electric shocks and internal damage, and prevents filter clogging, while ensuring safe operation and efficient dust collection without the need for bags or additional components.
Implementation Method 1
the at least one dust collection container consists at least partially of an electrically conductive plastic
Implementation Method 2
the at least one dust collection container is grounded during operation when it is pushed into the housing
Implementation Method 3
at least one filter unit, which is at least partially arranged in the housing and has at least one filter, which is provided in an operation for filtering suctioned air
Implementation Method 4
The suction device has at least one locking ring element, which is arranged on an inside of the dust collection container. The locking ring element is provided to prevent dust in the dust collecting container from being whirled up

AI summary
The invention relates to an extraction device, in particular a dental laboratory extraction device, comprising at least one housing (12a; 12b), at least one filter unit (14a; 14b) arranged at least partially within the housing (12a; 12b), which includes at least one filter (16a; 16b) designed for filtering extracted air (18a, 20a; 18b, 20b) during operation, and at least one removable dust collection container (22a; 22b) integrated into the housing (12a; 12b), designed as a dust drawer and intended for receiving filtered dust (24a; 24b). It is proposed that the at least one dust collection container (22a; 22b) be grounded when inserted into the housing (12a; 12b) during operation.
