Dust Box Docking Station for Reverse-Air Filter Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust extractor designs require manual cleaning of the filter, which can be inefficient and exposes the operator to debris, as current backflush systems only clean part of the filter effectively.
Innovation Solution
A docking station for the dust collection box that allows for the entire filter to be cleaned without removing it, using a system where air is drawn through the filter in reverse direction to dislodge and remove trapped dust, while the filter remains inside the dust collection box, utilizing a housing with specific apertures and internal guides to manage airflow and connect to a vacuum source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cleaning of the filter is used, then the filter can be cleaned, but the operator is exposed to debris and the process is inefficient
Solution Approach 1:
The system enables self-service cleaning where the filter cleans itself through reverse airflow generated by the vacuum source, eliminating the need for manual intervention and operator exposure to debris
Solution Approach 2:
The invention uses pneumatic principles by directing reverse airflow through the filter using a vacuum source, allowing automated cleaning without manual handling of the filter or debris
2Productivity
If backflush system is used, then partial filter cleaning is achieved, but the entire filter is not cleaned effectively
Solution Approach 1:
The system inverts the normal airflow direction by using reverse airflow from a vacuum source to blow dust off the filter from the inside out, achieving complete cleaning rather than partial cleaning
Solution Approach 2:
The docking station provides a universal cleaning solution that can clean the entire filter surface area through the reverse airflow mechanism, not just specific portions
3Ease of operation
If filter is made removable for cleaning, then access to filter is provided, but the cleaning process requires manual handling and exposes operator to debris
Solution Approach 1:
The filter remains installed in the dust collection box during cleaning and performs self-service through automated reverse airflow, eliminating the need for removal and manual handling
Solution Approach 2:
The docking station acts as an intermediary device that enables cleaning without filter removal, serving as a bridge between the filter and vacuum source while keeping the filter in place

AI summary
A docking station for a dust collection box comprising: a housing (2000): a socket formed by the housing (2000) which is capable of receiving a dust collection box (36) of a dust extractor; a first aperture 2028 formed through a wall (2022) of the housing 2000 which aligns with an air outlet aperture (1032) of a dust collection box (36) when the dust collection box (36) is mounted within the socket; a second aperture (2030) formed through a wall (2022) of the housing (2000) which aligns with an air inlet aperture (1030) of a dust collection box (36) when the dust collection box (36) is mounted within the socket; a connector (2014) capable of being connected to a vacuum source; a dust channel (2040), mounted inside of the housing 2000, which provides a passageway (2042) between the second aperture (2030) and the connector (2014); at least one air vent (2012) formed through a wall (2008) of the housing (2000) to allow air surrounding the housing (2000) to enter a cavity formed inside of the housing (2000); wherein the first aperture (2028) is connected to the cavity in the housing (2000) to allow air in the cavity to exit the housing (2000) through the first aperture (2028).
