Dust Collector Assembly With Telescoping Suction Pipe Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collectors for hand-held power tools often require frequent removal of the dust container during drilling operations, interrupting productivity due to excessive dust accumulation, and lack adjustable suction pipe lengths to accommodate varying drill bit depths.
Innovation Solution
A dust collector with a telescoping suction pipe, an adjustable depth stop assembly, and a removable filter system, allowing for automatic length adjustment and reduced interruptions during drilling, and enabling the dust collector to be easily repositioned on either side of the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the dust container capacity is increased, then dust collection effectiveness is improved, but the frequency of dust disposal interruptions increases
Solution Approach 1:
The dust container is divided into multiple compartments or sections, allowing the container to be partially emptied without removing the entire container from the device. This segmentation enables selective disposal of accumulated dust while maintaining the container's attachment to the device, thereby reducing interruptions and maintaining productivity.
2Device complexity
If the suction pipe length is fixed, then device simplicity is maintained, but adaptability to varying drill bit depths is reduced
Solution Approach 1:
The suction pipe is designed with telescopic or adjustable sections that allow its length to be dynamically changed according to the drill bit depth requirements. This dynamic adjustment capability enables the suction pipe to adapt to various drilling depths while maintaining a relatively simple overall structure when not in use.
3Device complexity
If the depth stop assembly is fixed on one side, then assembly simplicity is maintained, but repositioning flexibility is reduced
Solution Approach 1:
The depth stop assembly is designed with symmetric mounting features that allow it to be installed on either the left or right side of the device. This universal design enables the assembly to serve multiple positioning configurations without requiring different assembly structures, thereby maintaining simplicity while providing repositioning flexibility.

AI summary
A dust collector for use with a hand-held power tool includes a housing, a suction pipe coupled to the housing, and an electric motor positioned in the housing. The dust collector additionally includes a suction fan driven by the electric motor and operable to generate a vacuum in the suction pipe, and a depth stop assembly. The depth stop assembly is configured to limit the axial movement of the suction pipe. The depth stop assembly is configured to be alternately positioned on opposite sides of the suction pipe in a first configuration and a second configuration, respectively.
