Solution Overview
Problem
Existing vacuum cleaners face issues with dust sticking to filters, leading to reduced efficiency and user inconvenience during dust discharge, as dust and fine dust become tangled and difficult to separate, hindering airflow and requiring complex or incomplete discharge processes.
Innovation Solution
A dust collecting device with multiple cyclones that separates dust and fine dust using centrifugal force, featuring a mesh filter and a compressing device to facilitate easy discharge by compressing dust and fine dust into separate storage units, allowing simultaneous and efficient discharge through a single operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter is used to separate dust from air, then dust separation is achieved, but dust sticks to the filter causing reduced efficiency and airflow obstruction
Solution Approach 1:
The patent extracts the harmful function of dust adhesion from the filter by introducing a blowing device that actively removes dust particles from the filter surface. This prevents dust accumulation that would otherwise block airflow, maintaining both separation efficiency and airflow productivity without requiring filter replacement or manual cleaning.
Solution Approach 2:
The blowing device enables the filter to self-clean by blowing air through it to remove accumulated dust. This self-service mechanism automatically maintains filter performance without external intervention, preventing the deterioration of airflow efficiency while preserving dust separation capability.
2Quantity of substance
If dust is collected in a dust collecting device, then dust collection is achieved, but dust discharge becomes complicated and dust may blow unintentionally
Solution Approach 1:
The blowing device automatically blows collected dust toward the discharge port without requiring manual intervention. This self-service dust discharge mechanism eliminates the need for complex user operations while preventing unintentional dust scattering by directing airflow in a controlled manner toward the designated discharge location.
Solution Approach 2:
The blowing device acts as an intermediary between the collected dust and the discharge port, using airflow as a mediator to transport dust particles. This intermediary mechanism simplifies the discharge process by automatically moving dust through the system rather than requiring direct user handling, thereby improving ease of operation while maintaining collection capacity.
3Quantity of substance
If dust and fine dust are collected together, then collection capacity is maximized, but dust and fine dust become tangled and difficult to separate during discharge
Solution Approach 1:
The patent applies different local qualities to dust and fine dust by using a mesh filter that selectively separates them based on particle size. The blowing device then applies differentiated airflow treatment, effectively moving both particle types through separate paths that prevent tangling, thereby maintaining collection capacity while reducing separation complexity during discharge.
