Integrated Vacuum Drill Bit Assembly for On-Tool Dust Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dust collection methods for power tools require users to choose between a dust collector with a shroud-type dust inlet or a stand-alone vacuum, each with its own drawbacks, such as limited mobility and separate equipment needs.
Innovation Solution
A hand-held power tool assembly that integrates a dust collector with a motor-driven suction fan and a vacuum drill bit, where the dust collector is supported by the power tool and includes a suction pipe and dust collection chamber, allowing for efficient dust collection directly at the drilling site without separate equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a dust collector with a shroud-type dust inlet is attached to the power tool, then dust collection is improved, but device complexity and mobility are worsened
Solution Approach 1:
The patent combines the dust collector and vacuum drill bit into a single integrated assembly that attaches to the power tool. The dust collector housing incorporates both the suction inlet and the drill bit with internal passageways, merging two separate functions (dust collection and drilling) into one unified device. This eliminates the need for separate dust collectors and stand-alone vacuums, reducing overall device complexity while maintaining effective dust collection.
2Object-affected harmful factors
If a stand-alone vacuum is used with a vacuum drill bit, then dust collection is improved, but mobility and ease of operation are worsened
Solution Approach 1:
The invention integrates the vacuum function directly into the drill bit assembly through internal passageways that channel dust and debris from the drilling site directly into the dust collector container. This eliminates the need for separate stand-alone vacuum units that require grounding or backpack carrying, allowing the entire system to be held and operated as a single hand-held unit, thereby significantly improving mobility and ease of operation.
3Object-affected harmful factors
If separate dust collection equipment is used, then dust collection capability is improved, but device complexity and setup time are worsened
Solution Approach 1:
The integrated design combines the dust collector, suction system, and vacuum drill bit into a single pre-assembled unit that attaches directly to the power tool in one operation. The dust collector housing contains all necessary components including the suction inlet, internal passageways, and debris container, eliminating the need for multiple separate equipment pieces and their associated setup procedures. This single-attachment setup significantly reduces preparation time while maintaining comprehensive dust collection capability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This integrated solution enhances dust collection efficiency and mobility by allowing dust to be collected directly at the source, reducing exposure to workers and facilitating easy disposal of debris without the need for additional equipment.
Implementation Method 1
The dust collector includes a motor, a suction fan driven by the motor... A dust flow path extends through the vacuum drill bit, the suction connector, and the suction pipe to deposit dust in the dust collection chamber
