Dust Collecting Attachment for Power Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collecting attachments for power tools are not optimized for efficient dust collection during both hammering and drilling operations, leading to inefficiencies and interruptions for dust disposal.
Innovation Solution
A dust collecting attachment with a detachable dust collecting member that can be attached to a non-rotational auxiliary handle, featuring a connecting hose for forced suction into a dust collector, and interchangeable dust collecting members designed for specific operation modes to enhance dust collection efficiency and workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dust is collected only in a dust collecting cup without forced suction, then the structure is simple, but dust disposal requires additional manual processes and interrupts operation
Solution Approach 1:
The patent applies pneumatic principles by using a dust collector with a suction source that generates negative pressure to forcibly suction dust through a connecting hose from the dust collecting cup. This automated pneumatic system eliminates manual dust disposal operations while maintaining relatively simple device structure.
2Productivity
If a single dust collecting cup is used for both hammering and drilling operations, then the device is simple, but dust collection efficiency is insufficient for different operation modes
Solution Approach 1:
The patent divides the dust collection system into multiple detachable dust collecting members (first dust collecting member for hammering operation and second dust collecting member for drilling operation) that can be selectively attached to the auxiliary handle. This segmentation allows optimization of dust collection efficiency for each specific operation mode while maintaining ease of use through simple attachment and detachment.
3Ease of manufacture
If the dust collecting attachment is mounted directly on the tool body, then the mounting structure is simple, but modification of the tool body is required
Solution Approach 1:
The patent introduces an auxiliary handle as an intermediary component between the tool body and the dust collecting attachment. The auxiliary handle is retrofitted to the existing tool body and provides a mounting interface for the dust collecting attachment, thereby avoiding direct modification of the tool body while maintaining a relatively simple overall structure.
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 solution enables efficient dust collection during both hammering and drilling operations without interrupting tool use, eliminating the need for manual dust disposal and improving workability by using the appropriate dust collecting member for each mode.
Implementation Method 1
a connecting hose for connecting the dust collecting member to a dust collector... dust within the dust collecting member can be forcibly sucked by the dust collector

AI summary
It is an object of the invention to provide a technique that contributes to rationalization of dust collection, in a dust collecting attachment for use on a power tool. Dust collecting attachments 250, 350 are used on a power tool 201 having a tool body 203, a tool bit 209 which can be coupled to a front end region of the tool body 203, and an auxiliary handle 208 attached to the tool body 203. The dust collecting attachments 250, 350 include dust collecting members 251, 351, respectively, which can be attached to the auxiliary handle 208 in such a manner as to surround the front end region of the tool body 203 around a longitudinal axis of the front end region in order to collect dust generated during operation by the power tool 201, and a connecting hose 273 for connecting the dust collecting members 251, 351 to a dust collector.
