Axially Movable Suction Attachment for Deep Borehole Dust Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction attachments for insert tools are not optimally adaptable to changing borehole depths during drilling, leading to suboptimal suction performance and ergonomic issues.
Innovation Solution
A suction attachment designed for axial movement and rotation relative to the insert tool, featuring a housing with a front opening and suction opening forming a transport channel, a storage unit for secure mounting, and a bearing unit allowing for adjustable positioning to maintain effective suction and prevent slipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction attachment is fixed rigidly on the tool, then the structure is simple and stable, but the suction performance deteriorates with increasing borehole depth due to inability to adapt position
Solution Approach 1:
The suction attachment is designed with a bearing unit that enables axial movement and rotation relative to the tool, transforming the rigid fixed connection into a dynamic adjustable connection. This allows the attachment to adapt its position automatically during drilling operations, maintaining optimal suction performance across varying borehole depths while incorporating only minimal moving components
2Adaptability or versatility
If the suction attachment is made axially movable and rotatable, then the adaptability to borehole depth improves, but the stability and risk of slipping increases
Solution Approach 1:
The bearing unit provides controlled axial movement and rotation capability, allowing the attachment to adapt to different borehole depths while maintaining contact with the workpiece through a flat contact surface that prevents unwanted slipping
Solution Approach 2:
The flat contact surface on the front opening of the housing provides friction-based stabilization, allowing the attachment to maintain its position on the workpiece while still permitting the necessary axial and rotational adjustments through the bearing unit

AI summary
The invention relates to a suction-extraction attachment for an insertion tool, comprising a housing having an end-side opening, which is designed to accommodate the insertion tool, also comprising a bearing unit for mounting the suction-extraction attachment on the insertion tool, and further comprising a suction-extraction opening for coupling the suction-extraction attachment to a suction-extraction device, wherein the end-side opening and the suction-extraction opening form a transporting channel. It is proposed that the suction-extraction attachment should be mounted on the insertion tool by means of the bearing unit in an axially movable and rotatable manner such that the position of the suction-extraction attachment relative to the insertion tool alters as a drill-hole depth increases.
