Pivotable Dust Collection Mount for Handheld Power Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material collection devices for hand-held power tools are limited in their flexibility and compatibility with different discharge nozzles, often restricting the range of motion and increasing the risk of collision with the tool or workpiece.
Innovation Solution
A material collection device with a channel element and adapter housing that allows for flexible positioning and compatibility with various hand-held power tools, minimizing collision risks by adjusting the angle and alignment of the collection container relative to the discharge nozzle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the material collection container is rigidly mounted on the hand-held power tool, then the connection is secure and stable, but the range of motion is restricted and collision risk increases
Solution Approach 1:
The mounting unit incorporates a pivotable connection between the channel element and the material collection container, allowing the container to rotate relative to the power tool. This dynamic connection maintains secure attachment while enabling adaptive positioning to avoid collisions and accommodate different working angles, resolving the contradiction between connection stability and range of motion.
2Device complexity
If the mounting unit is designed for fixed positioning, then the structure is simple and robust, but compatibility with different discharge nozzles is limited
Solution Approach 1:
The mounting unit is designed with a universal adapter housing and channel element configuration that can accommodate various discharge nozzle types and angles. The pivotable connection and standardized mounting interface allow the same mounting unit to work with different hand-held power tools and discharge nozzle configurations, achieving compatibility without significantly increasing structural complexity.
3Productivity
If the channel element is positioned close to the discharge nozzle, then material collection efficiency is high, but collision with the tool or workpiece is more likely
Solution Approach 1:
The pivotable mounting unit allows the material collection container to be dynamically positioned closer to the discharge nozzle for efficient material collection, then rotated away from potential collision paths. This dynamic adjustment enables the system to optimize collection efficiency while avoiding collisions with the tool or workpiece during operation.

AI summary
The invention relates to a material collection device for a hand-held power tool, with a material collection container (112a) for collecting materials removed during operation of the hand-held power tool, wherein at least one opening (120a) of the material collection container (112a) for feeding the material into the material collection container (112a) is arranged in an opening plane (122a), and with at least one mounting unit (124a) for mounting the material collection container (112a) on the hand-held power tool. It is proposed that the mounting unit (124a) comprises a channel element (126a) for connection to an ejection port (76a; 76b; 76c; 76d) of the hand-held power tool, wherein a channel longitudinal axis (84a) of the channel element (126a) is arranged transversely to the opening plane (122a) of the material collection container (112a) in at least one section plane running perpendicularly to the opening plane (122a).
