Power Tool Dust Attachment With Elastic Claw Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collecting attachments for power tools are difficult to attach, requiring time and effort, as they often involve complex hose direction adjustments and multiple components.
Innovation Solution
A dust collecting attachment with an elastically deformable engagement piece featuring a claw that easily engages with the power tool's housing at a predetermined position, allowing for quick and stable attachment, and a discharging part that intersects the housing's direction to minimize interference with the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dust collecting attachment uses a complex hose direction adjustment mechanism to achieve versatile dust collection, then adaptability is improved, but device complexity increases and attachment time increases
Solution Approach 1:
The patent extracts the complex hose direction adjustment mechanism from the dust collecting attachment, separating the dust collection function from the directional adjustment function. The attachment focuses solely on providing a stable mounting interface, while hose positioning is simplified to a fixed or minimally adjustable configuration, thereby reducing overall device complexity while maintaining dust collection effectiveness.
Solution Approach 2:
The dust collecting attachment is segmented into distinct functional components: a mounting interface for attaching to the power tool, a body housing the collection chamber, and a simplified discharge interface. This segmentation allows each component to be optimized independently, with the mounting interface providing secure attachment without requiring complex adjustment mechanisms.
2Adaptability or versatility
If a dust collecting attachment uses multiple components and complex hose direction adjustments, then dust collection coverage is improved, but attachment time increases
Solution Approach 1:
The mounting interface is designed with pre-positioned engagement features including positioning protrusions and corresponding recesses, as well as pre-configured elastic engagement pieces. These preliminary configurations allow the attachment to be quickly connected to the power tool without requiring complex assembly steps or adjustments during the attachment process, significantly reducing attachment time.
Solution Approach 2:
The elastic engagement pieces automatically engage with the power tool housing when the attachment is brought into position, and the positioning protrusions self-align with the recesses. This self-service mechanism eliminates the need for manual adjustment or complex fastening procedures, allowing rapid attachment while maintaining secure connection and adequate dust collection coverage.
3Ease of operation
If a dust collecting attachment uses an elastic engagement piece with claw for simple attachment, then ease of operation is improved, but engagement strength may be insufficient
Solution Approach 1:
The engagement piece is designed with non-uniform cross-sectional geometry, featuring thicker regions at critical engagement points and thinner regions in non-critical areas. This local quality variation allows the engagement piece to provide sufficient strength at the claw engagement point while maintaining elasticity for easy operation. The positioning protrusions are also designed with localized reinforcement to ensure stable engagement with the power tool housing.

AI summary
A dust collecting attachment removably attachable to a power tool that includes a housing and a spindle: a covering part formed such that a drive axis of a spindle passes through the inside of a suction hole in the attached state of the power tool and at least partially covers a periphery of the tool mounting part; a discharging part connected to the covering part and configured to discharge dust from the inside of the covering part; and at least one elastically deformable engagement piece connected to the covering part and having a claw configured to engage with the housing at a predetermined position of the housing.
