Core Drill Suction Coupling With Adjustable Hose Angle Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional core drilling systems face inefficiencies in dust extraction, as existing methods either restrict the use of permanently mounted drilling aids or result in an unsightly and cumbersome hanging suction hose due to gaps between the tool and suction device.
Innovation Solution
A system with a suction connection device that interacts with the tool device through a toothing and counter-toothing mechanism, allowing for adjustable fastening levels to fix or rotate the suction hose relative to the tool handle, preventing unwanted rotation and allowing easy angle adjustment of the suction hose.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the suction connection device is rigidly fixed to the tool handle, then the suction hose position is stable, but the adaptability to different working positions is reduced
Solution Approach 1:
The suction connection device incorporates a rotatable joint mechanism that allows the suction hose to be fixed at multiple discrete angular positions. The toothing and counter-toothing engagement provides stable positioning at each stage while enabling rotation between stages, thus achieving both stability and adaptability.
Solution Approach 2:
The connection device is divided into discrete fastening stages with toothing elements that engage at specific angular positions. This segmentation allows the suction hose to be locked at predetermined angles while maintaining the ability to adjust between different working positions.
2Ease of operation
If a toothing and counter-toothing mechanism is used for connection, then the ease of operation for angle adjustment is improved, but the device complexity increases
Solution Approach 1:
The toothing and counter-toothing mechanism enables dynamic adjustment between fixed angular positions. The user can easily rotate the suction connection device to different stages and lock it in place, providing simple operation despite the mechanical complexity of the engagement mechanism.

AI summary
The present invention relates to a tool-device system and to a method for connecting a vacuum cleaning appliance to a tool device. The system comprises: a tool device having a tool; a vacuum cleaning appliance for suctioning dust produced during work using the tool device; and a suction connection apparatus, the suction connection appliance being arranged between the tool of the tool device and the tool device and being able to be connected to the tool device by the bringing of teeth of the tool device into engagement with counter teeth on the vacuum cleaning appliance. The present invention advantageously allows a suction hose, which interconnects the vacuum cleaning appliance and the suction connection apparatus of the tool-device system, to be fixed relative to a handle of the tool device. Furthermore, an angle between the suction hose and the handle of the tool device can be set in a particularly simple manner.
