Power Tool Dust Capture Accessory for Tight-Space Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power tool accessories for capturing dust and debris are inefficient due to suboptimal airflow direction, inability to reach corners and under cabinets, durability issues, and clogging problems, which complicates the removal of flooring tile and poses health and environmental concerns.
Innovation Solution
A debris-collecting tool accessory with a housing featuring an interior passageway and exit passage for tool shafts, a nose with sloping upper and lower faces, elliptical suction ports, and a clamp with vent holes, allowing for improved airflow and debris collection while preventing clogging, and a flexible chip guard for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single large opening is used in the housing, then dust capture capability is improved, but the tool cannot reach certain places such as corners and underneath cabinets
Solution Approach 1:
The housing is divided into multiple sections with multiple openings instead of a single large opening. This segmentation allows the tool to navigate tight spaces while maintaining effective dust capture through the combined area of multiple openings.
Solution Approach 2:
The housing shape is changed from a conventional form to a flat profile that can slide under cabinets and into corners. This dimensional change enables access to previously unreachable areas while the multiple openings distributed across the housing surface maintain dust capture effectiveness.
2Productivity
If the vacuum attachment location is optimized for airflow, then dust capture efficiency is improved, but the device complexity increases
Solution Approach 1:
The housing structure serves multiple functions simultaneously: it provides the vacuum attachment interface, directs airflow, and captures dust from multiple openings. This multi-functionality reduces overall device complexity while maintaining optimized airflow and dust capture efficiency.
3Strength
If a cylindrical housing shape is used, then structural strength is improved, but the tool lacks stability when moved along the floor
Solution Approach 1:
The housing transitions from a cylindrical shape to a flat profile with strategic curvature elements. The flat base provides stability during movement along the floor, while curved reinforcement elements maintain the necessary structural strength to withstand operational forces.

Function Achieved in This Case
The solution enhances the speed and efficiency of tile and debris removal by minimizing collisions and allowing for effective dust collection, maintaining a clean environment, and adhering to environmental regulations by maximizing dust capture and tool durability.
Implementation Method 1
an exit passage configured to couple with a negative pressure source
Implementation Method 2
a suction port plate coupled to the housing and the nose, the suction port plate comprising a plurality of suction ports

AI summary
A system and method for capturing dust from power tool operation are disclosed. The system comprises a debris-collecting accessory that includes a body and a nose. The nose has an opening for a toolbit and at least one suction port that opens into an interior volume of the housing. The body has a second end configured to couple to a power tool. An exhaust tube attaches to the exterior surface of the body such that an interior volume of the exhaust tube connects to an interior volume of the housing. An exit passage is coupled to the exhaust tube and is configured to couple to a vacuum.
