Vacuum Device with Adjustable Wall for Moving Tool Dust Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum devices struggle to efficiently collect dust generated during slotting operations, as the drilling tool moves relative to the vacuum device, making it difficult to intercept and remove the material produced.
Innovation Solution
A vacuum device with adjustable wall sections that can pivot open to accommodate tools moving relative to the device, allowing for a larger inlet area and reliable collection of dust through a connection to a suction unit, ensuring effective vacuuming even when the tool is not stationary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the working space is kept closed to maintain negative pressure, then vacuum efficiency is improved, but adaptability to moving tools deteriorates
Solution Approach 1:
The wall section is made dynamically adjustable between closed and open positions. This allows the vacuum device to adapt its working space configuration based on whether the tool is stationary (drilling) or moving (slotting), resolving the contradiction between maintaining negative pressure and accommodating tool movement.
Solution Approach 2:
The wall is segmented into a movable wall section that can be independently adjusted. This segmentation allows partial opening of the working space while maintaining sealing in other areas, enabling adaptability without completely compromising vacuum efficiency.
2Adaptability or versatility
If the wall section is made adjustable to accommodate moving tools, then adaptability is improved, but device complexity increases
Solution Approach 1:
A simple pivoting mechanism is used to create adjustability in the wall section. This dynamic element allows the structure to transform from closed to open configuration without requiring complex actuators or control systems, thus improving adaptability while minimizing complexity increase.
Solution Approach 2:
The opening angle of the wall section can be adjusted to optimize the inlet area for different tool movements. This parameter adjustment allows adaptation to various working conditions (drilling, slotting, etc.) without fundamentally changing the device structure.
3Productivity
If the inlet area is increased to collect dust from moving tools, then dust collection effectiveness is improved, but negative pressure maintenance becomes difficult
Solution Approach 1:
The wall is segmented so that only the necessary portion (wall section) can be opened to create the inlet area. This controlled segmentation allows dust collection from moving tools while minimizing the opening to maintain negative pressure in the remaining sealed portions of the working space.
Solution Approach 2:
The opening is created locally at the wall section rather than opening the entire working space. This localized quality change allows dust ingress at a specific point while maintaining negative pressure and sealing in other critical areas of the chamber.
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
The adjustable design allows for reliable dust collection during various construction processes, including slotting, by providing a larger opening for material collection and maintaining a sealed negative pressure chamber for efficient vacuuming, even on vertical surfaces.
Implementation Method 1
A negative pressure is created in the negative pressure chamber, which ensures that the vacuum device is pulled against the masonry

AI summary
A vacuum device is used when working with a tool in masonry to vacuum dust that is produced. The device has at least one negative pressure chamber, at least one working space and a connection for a suction unit, of which the working space is delimited by a wall. In order to be able to reliably vacuum out the dust produced when working with different tools at any time using the vacuum device while having a simple design, the wall delimiting the working space has at least one wall section which can be adjusted into a position that opens the working space.
