Power Tool Dust Collector Clamp for Multi-Size Tool Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collectors for power tools lack a standardized and adaptable mechanism for secure attachment to various rotary power tools, leading to inefficiencies in dust collection and debris management during drilling operations.
Innovation Solution
A dust collector design featuring a modular structure with a telescoping suction pipe and a fastening system using a band clamp and clamping device, allowing for easy attachment to standard clamping necks of different sizes, and an auxiliary handle with clamps and notches for secure positioning, enabling efficient dust collection and debris management across multiple tool sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dust collector is designed with a fixed attachment mechanism, then it provides stable attachment to one specific tool size, but it cannot be adapted to various rotary power tools of different sizes
Solution Approach 1:
The dust collector is designed with a universal attachment mechanism that can accommodate multiple rotary power tool sizes through a single standardized interface. The clamping device with adjustable band and multiple notch positions enables one dust collector design to work with various tool diameters, eliminating the need for multiple specialized attachments.
Solution Approach 2:
The attachment mechanism incorporates dynamic elements including an adjustable band clamp that can be positioned at different locations around the clamping neck, and a clamping device with movable clamps that can engage with notches at various angular positions. This dynamic configuration allows the same mechanism to adapt to different tool sizes while maintaining secure attachment.
2Reliability
If a dust collector uses a simple attachment mechanism, then it reduces device complexity, but it fails to provide secure attachment across different tool sizes
Solution Approach 1:
The attachment mechanism is divided into separate functional components: a band clamp for circumferential compression, a clamping device with individual clamps for localized engagement, and multiple notches for positional reference. This segmentation allows each component to perform its specific function effectively while working together to provide secure attachment across various tool sizes.
Solution Approach 2:
The clamping device acts as an intermediary mechanism between the dust collector body and the rotary power tool. It translates the user's tightening action into a secure, multi-point engagement with the tool's clamping neck, ensuring reliable attachment while accommodating size variations through its adjustable geometry.
3Adaptability or versatility
If a dust collector is designed with multiple clamps and notches for secure attachment, then attachment reliability improves, but the device complexity increases
Solution Approach 1:
Multiple clamping functions are merged into a single integrated clamping device that operates through one tightening motion. The band clamp and individual clamps work together as a unified system, allowing the user to secure the dust collector to the tool with a single rotational action rather than multiple separate fastening steps.
Solution Approach 2:
The attachment mechanism incorporates self-aligning features where the clamps naturally guide themselves into the notches during the tightening process. The geometry of the clamps and notches is designed so that proper engagement occurs automatically as the band is tightened, reducing the precision and effort required from the user.

AI summary
An auxiliary handle is for use with a power tool having a housing that includes a first notch and a second notch. The auxiliary handle includes a shaft, a first clamp coupled to the shaft and having a first protrusion configured to engage the first notch, and a second clamp arranged on the shaft and having a second protrusion configured to engage the second notch. When the first protrusion of the first clamp engages the first notch, the second clamp is movable along the shaft between a first position, in which the second protrusion engages the second notch, and a second position, in which the second protrusion is disengaged from the second notch. The auxiliary handle also includes a grip coupled to the shaft. When the grip is rotated relative to the second clamp, the second clamp is moved from the second position toward the first position.
