Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaners face inefficiencies in dust separation and storage, particularly in up-right and canister types, where dust collection systems often lack effective cyclone separation mechanisms and compact designs, leading to reduced air-dust separation performance and increased size.
Innovation Solution
A dust collecting apparatus integrated with a vacuum cleaner, featuring a first dust separator using the cyclone principle, a second dust separator with non-parallel cyclone parts for enhanced airflow, and a compact structure, along with a compressing unit and cover assembly for efficient dust storage and discharge prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional dust collection system is used in up-right or canister vacuum cleaners, then the structure is simple, but the air-dust separation performance is reduced and the device size increases
Solution Approach 1:
The patent implements a nested cyclone structure where a second cyclone is positioned inside the first cyclone, and a third cyclone is positioned inside the second cyclone. This nested arrangement allows multiple dust separation stages to be compacted into a small space, achieving high air-dust separation performance without increasing the overall device volume.
Solution Approach 2:
The dust collection system is divided into multiple independent cyclone separators (first, second, and third cyclones) that operate in sequence. Each cyclone handles a specific stage of dust separation, with the first cyclone performing primary separation, the second cyclone performing secondary separation, and the third cyclone performing tertiary separation. This segmentation enables efficient dust removal while maintaining a compact design.
2Reliability
If dust is stored in a dust storage container, then dust collection is achieved, but dust may scatter during storage and discharge
Solution Approach 1:
The patent employs a pressing member that compresses dust into the dust storage container before the dust is fully collected. This preliminary compression action reduces the volume of stored dust and prevents dust particles from scattering during storage and subsequent discharge operations, thereby improving dust storage efficiency and eliminating harmful dust scattering.
3Volume of stationary object
If a compact dust collecting apparatus is designed, then the device size is reduced, but the dust separation capability may be compromised
Solution Approach 1:
The patent achieves compact size while maintaining dust separation capability by nesting multiple cyclones within each other. The first cyclone, second cyclone, and third cyclone are arranged in a nested configuration, allowing three stages of dust separation to occur within the volume of a single cyclone, thus maintaining high separation capability in a compact apparatus.
Solution Approach 2:
The patent utilizes vertical stacking and radial arrangement of cyclones to optimize space utilization. By arranging cyclones in both vertical and radial dimensions, the system achieves multi-stage dust separation without proportionally increasing the apparatus volume, thereby maintaining compact size while preserving dust separation capability.
