Sander Vacuum Nozzle Attachment with Wing Apertures for Dust Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collection systems for orbital/vibrating sanders are inefficient, allowing dust to escape and reducing the lifespan of sandpaper due to holes in dust collection bags.
Innovation Solution
A dust wing adapter that attaches to a sander and a vacuum system, featuring a hollow body with central intake and outlet apertures, and a pair of wings with intake apertures to capture and direct dust into the vacuum system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If dust collection bags are added to sanders, then dust containment is improved, but sandpaper lifespan is reduced due to holes in the bags
Solution Approach 1:
The patent introduces a vacuum system as an intermediary component between the sander and the dust collection bag. The vacuum system creates negative pressure that draws dust through the sandpaper and into the collection bag without requiring holes in the bag itself, thus protecting the sandpaper while maintaining dust containment effectiveness
Solution Approach 2:
The patent employs pneumatic principles by using vacuum pressure to move dust particles. The vacuum system creates a pressure differential that pulls dust through the sandpaper and into the collection bag, replacing mechanical dust collection methods that caused sandpaper damage
2Object-affected harmful factors
If dust collection bags with holes are used, then dust capture is improved, but dust escapes and contaminates surrounding surfaces
Solution Approach 1:
The vacuum system acts as an intermediary that creates a controlled airflow path. It draws dust through the sandpaper and directly into the collection bag through sealed connections, preventing dust from escaping into the surrounding environment while maintaining effective dust capture
Solution Approach 2:
The vacuum system creates a controlled, negative pressure environment that prevents dust from escaping. By maintaining continuous suction and sealed connections between components, the system ensures dust remains contained within the collection bag rather than contaminating the surrounding workspace
3Productivity
If traditional dust collection systems are used, then some dust is captured, but most dust remains free and requires additional cleaning
Solution Approach 1:
The vacuum system serves multiple functions simultaneously: it captures dust at the sanding source, contains it within the collection bag, and eliminates the need for additional cleaning operations. This multi-functional approach maximizes dust capture efficiency while eliminating wasted cleaning time
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively captures dust generated by sanding, reducing contamination and extending sandpaper lifespan by efficiently directing dust into the vacuum system.
Implementation Method 1
an outlet aperture that attaches to the suction hose of the vacuum system... allow dust to be drawn into the hollow body by the vacuum system

AI summary
The present invention provides a sander vacuum nozzle attachment also known as a dust wing adapter that captures dust while sanding by attaching to a sander and a vacuum system. It comprises of a hollow body with a central intake aperture that attaches to the dust bag mount of the sander and an outlet aperture that attaches to the suction hose of the vacuum system. The device also features a pair of wings that are placed adjacent to the sanding head and to the work surface, each wing has multiple wing intake apertures which allow dust to be drawn into the hollow body by the vacuum system. The design is efficient and compatible with orbital sander and mouse sander, and the shop vac is used as vacuum system.
