Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction cleaners with cyclonic dirt separation systems face challenges in preventing debris re-entrainment into the collection chamber, which affects the efficiency of dirt separation and cleaning.
Innovation Solution
The implementation of a cyclone separator with a collection chamber featuring a single circumferential fin extending inwardly from the sidewall, designed to direct debris to the bottom of the chamber and prevent re-entrainment, combined with a two-stage separation system and a specific fin arrangement that optimizes debris separation and minimizes re-entrainment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a cyclone separator with collection chamber is used to separate contaminants from airstream, then separation efficiency is improved, but debris re-entrainment occurs reducing cleaning effectiveness
Solution Approach 1:
The collection chamber is segmented into multiple zones using circumferential fins that create distinct regions for debris accumulation and airflow. The fins divide the chamber into segments that guide debris to specific accumulation zones while maintaining separate airflow paths, preventing re-entrainment by spatial segmentation of contaminant and clean air regions.
Solution Approach 2:
The invention introduces a vertical dimension to debris management by using inclined fins that direct debris downward toward the bottom of the collection chamber. This dimensional approach creates a gravity-assisted debris flow path that separates contaminant movement from the horizontal airflow, effectively preventing re-entrainment by operating in a different spatial dimension.
2Reliability
If multiple fins are added to collection chamber to prevent re-entrainment, then debris separation is improved, but device complexity increases
Solution Approach 1:
Instead of uniformly distributing fins throughout the collection chamber, the invention applies fins with specific local qualities - particular spacing, angles, and positions - where they are most effective for directing debris. The fins are strategically placed to create optimal local flow patterns and debris accumulation zones, achieving reliable separation without the complexity of a fully distributed fin system.
Solution Approach 2:
The invention uses a partial fin arrangement that provides sufficient debris separation functionality without implementing a complete circumferential fin system. By applying fins to only the critical portions of the collection chamber where re-entrainment occurs, the design achieves adequate separation reliability while minimizing the complexity and number of fins required.

AI summary
A vacuum cleaner with a cyclone module assembly comprises a cyclone separation chamber for separating dust and debris from air and a collection chamber for collecting dust and debris that is separated from the air in the cyclone separation chamber. The cyclone module assembly further includes at least one feature for directing contaminants downwardly, such as a circumferential fin that extends from the inside wall of the collection chamber.
