Vacuum Device for Masonry Drilling Cuttings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for sucking off drill cuttings during drilling in masonry are ineffective when drilling on ceilings or floors, as the collection space is not in the fall area of the cuttings, leading to incomplete suction and surface staining, especially when the device is not held by hand.
Innovation Solution
The device separates the suction point from the vacuum space, using a connecting piece and suction sleeve with a guide bushing to ensure cuttings are directed into the suction hose, preventing staining and allowing for efficient suction regardless of drilling position, with a design that accommodates various drill diameters and allows for easy connection to a vacuum cleaner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the collection space is located in the fall area of drill cuttings (below drilling site for vertical walls), then cuttings can fall down into the collection space effectively, but the device cannot be used on ceilings or floors where cuttings do not fall downward
Solution Approach 1:
The device segments the collection function from the vacuum chamber by introducing a separate collection space connected via a connection channel. This allows the collection space to be positioned independently in the fall area while the vacuum chamber can be positioned above the drilling site, resolving the contradiction between reliable suction and adaptability to different drilling positions.
Solution Approach 2:
A connection channel acts as an intermediary between the collection space and the vacuum chamber, allowing cuttings to be transported from the collection space to the vacuum chamber regardless of the device's orientation. This mediator enables the device to function effectively on ceilings, floors, and vertical walls.
2Device complexity
If the drill passes through the vacuum chamber wall, then the device structure is simple, but cuttings enter the vacuum chamber and stain the masonry surface
Solution Approach 1:
The invention extracts the harmful function (cuttings entering the vacuum chamber) by introducing a separate collection space that intercepts cuttings before they can enter the vacuum chamber. The drill still passes through the wall simply, but cuttings are diverted into the collection space via the connection channel, preventing surface staining.
3Volume of stationary object
If the collection space has small capacity, then the device structure is compact, but cuttings are not sufficiently collected when drilling on ceilings or floors
Solution Approach 1:
The invention extends the collection capability into a new spatial dimension by adding a connection channel that leads to an additional collection space. This dimensional extension allows the device to effectively collect cuttings from multiple drilling positions (ceilings, floors, vertical walls) while maintaining a compact overall structure.
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
This design ensures reliable suction of drill cuttings over a large peripheral area, preventing surface staining and allowing operation on any surface without manual holding, with efficient connection to a vacuum cleaner, even when drilling on ceilings or floors.
Implementation Method 1
This creates a negative pressure in the negative pressure chamber, which ensures that the device is pulled against the masonry
Implementation Method 2
the suction unit, in particular a vacuum cleaner, connected to the extraction sleeve
Implementation Method 3
This creates a negative pressure in the negative pressure chamber, which ensures that the device is pulled against the masonry

AI summary
The device has a negative pressure chamber (5), suction point (14), and a connector for a suction unit that sucks a cutting accumulated on the suction point. A negative pressure chamber and the suction point are spatially separated from each other, where the suction point is limited by a guide bushing (15) for a drill (17). The guide bushing is accommodated in a suction casing (16), where the guide bushing is fixedly inserted in the suction casin that is replaceable with the guide bushing for diameter ranges of the drill.
