Wet Drilling Suction Housing for Core Holes Near Adjacent Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction devices for wet drilling are limited in their ability to operate close to adjacent walls due to the required distance between the inner and outer rings, which restricts their use in drilling near perpendicular or adjacent surfaces.
Innovation Solution
A suction device with a contact wall that can abut adjacent surfaces, eliminating the gap between the housing and the wall, allowing the device to be positioned very close to adjacent walls or ceilings, and featuring adjustable components and sealing mechanisms to ensure effective water collection and suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sufficient distance is maintained between the inner and outer rings to ensure adequate collection volume and suction effect, then suction performance is improved, but the device cannot be positioned close to adjacent walls
Solution Approach 1:
The housing is divided into two functional zones: a first zone with a sealed bottom for maintaining suction effect, and a second zone with an open bottom for positioning close to adjacent walls. This segmentation allows the device to maintain adequate collection volume for suction while adapting to restricted positioning spaces near walls.
Solution Approach 2:
The invention transitions from a fully enclosed ring structure to a partially open structure by removing the bottom plate in the second zone. This dimensional change allows the device to extend into the space between adjacent walls, enabling positioning in previously inaccessible locations while maintaining suction functionality in the sealed first zone.
2Reliability
If a sealed housing structure is used to maintain suction effect, then suction performance is improved, but the device cannot adapt to restricted spaces near adjacent walls
Solution Approach 1:
The housing is segmented into a first zone with a sealed bottom plate for maintaining suction effect and a second zone with an open bottom for adapting to restricted spaces. This allows the device to maintain reliability in the sealed zone while gaining adaptability through the open zone configuration.
Solution Approach 2:
The bottom plate is made detachable, transforming the housing from a static sealed structure to a dynamic configurable structure. This allows the housing to be adapted between sealed and open configurations depending on the drilling location requirements, enabling both suction effectiveness and positioning flexibility.
3Reliability
If the housing is fully enclosed to prevent water escape, then containment is improved, but positioning close to adjacent walls is prevented
Solution Approach 1:
The housing is divided into zones with different containment characteristics: a first zone with a sealed bottom for water containment and a second zone with an open bottom for close positioning to walls. This segmentation resolves the contradiction by providing containment where needed while enabling close positioning in restricted spaces.
Solution Approach 2:
Different portions of the housing have different structural qualities: the first zone maintains a sealed structure for water containment, while the second zone has an open structure for adapting to restricted spaces. This local differentiation allows the device to achieve both containment and close positioning capabilities.
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
Enables core drilling with minimal distance from adjacent walls or ceilings, maintaining suction efficiency and preventing water escape, while allowing for flexible positioning and adaptation to different drilling scenarios.
Implementation Method 1
Water and drilling mud are therefore collected directly on site at the drilling site in the water collection ring and can be sucked off, for example, by a wet-dry vacuum cleaner
Implementation Method 2
the edges of the rings have sealing lips

AI summary
The invention relates to a suction extraction device (11) for the collected removal of cooling water for wet drill-holes on a first building wall, comprising: a housing (13) on which a through opening (23) is provided for the passage of a hollow core drill or drill bit, the through opening (23) being delimited by an inner wall (15) of the housing (13) and a gap being defined between the inner wall (15) and an outer wall (17) of the housing (13); a suction connection (25) which is arranged on the outer wall (17) and is in connection with the gap; a first and a second sealing lip (29, 31) which are arranged on the edges of the inner and outer wall (15, 17) for sealingly retaining the housing (13) on the first building surface; and a cover (19), which connects the inner wall (15) and the outer wall (17) on the side facing away from the sealing lips (29, 31). The housing (13) comprises a first bearing wall (33) which has a lower and an upper edge and which replaces the inner wall (15) and outer wall (17) in a wall region and can bear on at least a second building face adjacent to the first building face.
