Suction device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Suction devices struggle to effectively collect drilling material when tools, such as slotting tools, move relative to the suction device, making it difficult to intercept and remove the material produced during the process.
Innovation Solution
A suction device with adjustable wall sections that can pivot into an open position to accommodate tools moving relative to the suction device, allowing for a larger inlet area and reliable collection of material, and sealing elements to maintain negative pressure and prevent escape of material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the working space is closed to maintain vacuum pressure, then suction effectiveness is improved, but adaptability to moving tools deteriorates
Solution Approach 1:
The wall section is made dynamically adjustable between closed and open positions. The hinged design allows the wall section to pivot from a closed position that maintains vacuum pressure to an open position that accommodates moving tools, resolving the contradiction between maintaining suction effectiveness and adapting to different tool movements.
2Productivity
If the inlet area is enlarged to capture material from moving tools, then material collection is improved, but device complexity increases
Solution Approach 1:
The housing wall is segmented into a fixed portion and a movable wall section. This segmentation allows the wall section to be independently pivoted to create openings of varying sizes, enabling flexible enlargement of the inlet area without redesigning the entire housing structure, thus improving material collection while controlling device complexity.
3Adaptability or versatility
If the wall section is made adjustable to accommodate moving tools, then versatility is improved, but ease of operation deteriorates
Solution Approach 1:
The wall section incorporates a hinge mechanism that enables simple pivoting motion between closed and open positions. This dynamic design allows operators to easily adjust the wall section to accommodate different tool movements without complex adjustment mechanisms, maintaining ease of operation while improving versatility.
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
Ensures reliable suction of material during various drilling and slotting operations, including on vertical surfaces, by creating a large collection area and maintaining effective negative pressure, allowing the user to focus on the task without manual holding of the suction device.
Implementation Method 1
A vacuum is created in the vacuum chamber, which draws the suction device against the masonry
Implementation Method 2
The suction unit draws the material generated during work with the tool through the opening into the connection

AI summary
The extraction device serves to extract material generated during work with a tool in masonry. It has at least one negative pressure chamber (11), at least one working chamber (15), and a connection (5) for a suction unit, the working chamber (15) being bounded by a wall (3, 12, 16). In order to reliably extract the material generated during work with different tools at all times with a simple design, the wall (3, 12, 16) bounding the working chamber has at least one wall section (16) that can be adjusted into a position opening the working chamber (15).
