Oscillating Tool Suction Connection Layout for Flexible Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-held power tools with suction connections positioned rearward interfere with the operation, limiting handling flexibility, especially when making cuts in directions other than straight forward.
Innovation Solution
The suction connection is relocated to the front area of the machine housing, allowing for improved grip and operation by positioning it on the drive section, with an adjustable covering device that can be moved between covering and release positions to optimize tool visibility and suction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suction connection is arranged in the rear handle section, then the suction channel does not interfere with the production of the separating cut, but the handling flexibility of the hand-held power tool is limited
Solution Approach 1:
The suction connection is made adjustable relative to the machine housing, allowing it to be moved between different positions (retraction and extension) to adapt to different operational requirements and workpiece configurations, thereby improving handling flexibility while maintaining effective chip suction
Solution Approach 2:
The suction connection is divided into separable components that can be independently positioned and adjusted, allowing the system to optimize both the suction function and the handling characteristics by distributing components to different locations on the machine housing
2Ease of operation
If the suction connection is arranged in the front area of the machine housing, then handling flexibility is improved, but the suction connection may interfere with operation when using a rearward-protruding handle
Solution Approach 1:
The suction connection is designed to be dynamically adjustable, allowing the operator to retract it when using a rearward handle to avoid interference, and extend it when front gripping is used, thus adapting to different operational modes without permanent interference
Solution Approach 2:
The adjustable suction connection system serves multiple functions: it can be positioned to accommodate different gripping styles (front or rear handle usage), different workpiece orientations, and different operational requirements, making the tool universally applicable to various cutting scenarios

AI summary
The invention relates to a hand-guided hand-held machine tool (10) for introducing a separating cut (T) into a workpiece (W) along a working direction (AR) using a cutting tool (40), wherein upon guiding the hand-held machine tool (10) along the workpiece (W), the cutting tool cuts into the workpiece (W). The hand-held machine tool has a drive (16) with a drive motor (16A) and a tool receiving area (19) for receiving the cutting tool (40), said tool receiving area being drivable in an oscillating manner back and forth relative to a drive axis (AL) by means of the drive (16), and the drive motor (16A) is received in a machine housing (12) of the hand-held machine tool, said tool receiving area (19) being arranged on a machine housing (12) base side (29), from which the cutting tool (40) protrudes in a use position arranged on the tool receiving area. A cutting contour (51) of the cutting tool (40) is oriented forwards in the working direction (AR), and the hand-held machine tool has a suction connection (15) for connecting a suction device (120), in particular a suction tool (110), in order to suction particles produced when machining the workpiece (W) using the cutting tool (40). The suction connection (15) is fluidically connected to a hand-held machine tool suction region (30), on or in which the tool receiving area is arranged. The suction connection (15) is arranged on a front machine housing (12) drive section (13) in the working direction.
