Suction Device Filter Maintenance via Detachable Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The filter medium in suction devices for hammer drills experiences wear and clogging due to vibrations and dirt entry, leading to reduced suction efficiency, and existing designs make filter maintenance difficult and costly, requiring complete dust collection container replacement.
Innovation Solution
A detachable clamping part with a ramp design allows for non-destructive removal and easy cleaning of the filter medium, and an insertion opening for the filter medium within the dust collection container enables tool-free replacement and extended service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the filter means is fixed in the dust collection container, then the structural stability is improved, but the ease of maintenance deteriorates
Solution Approach 1:
The filter means is divided into a separate, detachable component from the dust collection container. The support part for the filter means can be removed independently from the container, allowing maintenance without replacing the entire assembly. This segmentation enables the filter to be cleaned or replaced while keeping the container intact.
Solution Approach 2:
The mounting position of the support part is designed to be dynamically changeable between a mounted state (for operation) and a removed state (for maintenance). The support part can be easily inserted and removed from the dust collection container, providing both structural stability during use and ease of maintenance when needed.
2Reliability
If the filter means is permanently attached, then the reliability is improved, but the loss of time for maintenance increases
Solution Approach 1:
The support part is pre-designed with specific mounting features (such as engagement elements or geometric fitting) that enable quick and tool-free installation and removal. This preliminary design ensures that when maintenance is needed, the filter can be rapidly replaced without complex procedures, minimizing downtime while maintaining reliable operation during use.
3Ease of operation
If the filter medium is made accessible for cleaning, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The filter means is extracted as a separate, accessible component from the dust collection container. By making the support part detachable and independently removable, the filter medium becomes easily accessible for cleaning operations (such as compressed air blasting) without requiring disassembly of the entire container or complex access mechanisms, thus maintaining simple device architecture while improving ease of operation.

AI summary
A suction mechanism (2) has a housing body (4) with a suction mechanism mounted on the housing body. The suction mechanism has a tool setting area (12), a dust channel sink (10), and a dust collecting device (19). The dust collecting device is fixed to the housing body. A filter (28) containing a dust receptacle (20) is provided to which the dust sink leads into and which is subjected to negative pressure by a motor. The filter can be exchanged and or externally cleaned in the dust receptacle.
