Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction cleaners require user adaptation for wet or dry modes and suffer from rapid loss of suction power due to dust accumulation, limiting their versatility and effectiveness in both modes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dust-filtering bag or filter is used in the tank for dry matter separation, then dry matter can be collected, but suction power is rapidly lost due to dust accumulation on the filter
Solution Approach 1:
The patent extracts the filter element from the system by using a cyclonic separator that separates dust from air without any filter. The centrifugal force generated by the cyclone extracts dust particles from the airflow and collects them in a separate chamber, eliminating the filter that would otherwise accumulate dust and lose suction power.
Solution Approach 2:
The patent replaces the mechanical filtration system (filter bags or filters) with a cyclonic separation system that uses centrifugal force generated by rotating airflow. This mechanical substitution eliminates the need for filters that require maintenance and cause suction power loss when clogged.
2Adaptability or versatility
If the cleaner is adapted for wet mode with a liquid tank, then wet cleaning tasks can be performed, but the device complexity increases requiring user adaptation
Solution Approach 1:
The cyclonic separator design allows the same device to handle both wet and dry cleaning tasks effectively. The separator can process liquid-containing airflow in wet mode and dry dust-laden airflow in dry mode without requiring different separation mechanisms, providing universal functionality with a single device configuration.
Solution Approach 2:
The system dynamically adapts to different operating modes (wet or dry) through the user-selectable liquid delivery mechanism. The liquid delivery device can be activated or deactivated based on the cleaning task, allowing the same physical system to optimize its performance for different conditions without structural changes.
3Manufacturing precision
If liquid is introduced into the suction airflow, then fine dust particles are attracted to water particles and separated more effectively, but the device complexity increases with liquid delivery system
Solution Approach 1:
The patent introduces liquid droplets as an intermediary substance that facilitates the separation of fine dust particles from airflow. The liquid acts as a mediator that captures fine particles through attraction, causing them to coalesce and separate more effectively in the cyclonic separator, thereby improving dust separation effectiveness.
Solution Approach 2:
The system changes the physical parameters of the airflow by introducing liquid droplets, which alter the density and separation characteristics of the air-dust mixture. This parameter change enhances the cyclonic separator's ability to separate fine particles by modifying the interaction between particles and airflow.
