Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial vacuum cleaners and household vacuum cleaners face challenges with filtration layers that accumulate dust or impurities, as the filtration layers are difficult to replace (or have high replacement cost) after long-term use, which affects subsequent use.
Innovation Solution
A dust collection structure with a ventilation channel inside the dust collection structure body, connected to the outside through ventilation openings, featuring a curved and irregular shape, and interconnected channels with fluffs and hydrophilic layers for enhanced dust adhesion, and a spray structure for simultaneous cleaning and adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filter cloth or filtration layers are used for dust filtration, then dust collection effect is achieved, but the filtration layers become blocked and difficult to replace after long-term use
Solution Approach 1:
The filtration system is divided into two separable parts: the dust collection structure body (which accumulates dust) and the ventilation channel (which allows airflow). This segmentation enables the dust collection structure body to be easily removed and replaced when blocked, while the ventilation channel remains in place. The modular design resolves the contradiction by making the filtration component detachable and replaceable without affecting the overall system structure.
Solution Approach 2:
The dust collection structure body is extracted as a separate, removable component from the ventilation system. This extracted component can be easily removed when dust accumulation causes blockage, eliminating the need to replace the entire filtration system. The extraction principle allows users to simply take out the dust collection structure body for cleaning or replacement, significantly improving ease of operation while maintaining filtration effectiveness.
2Reliability
If filter cloth is used for filtration, then dust is adsorbed, but the filter cloth becomes blocked and requires frequent replacement
Solution Approach 1:
The dust collection structure body is designed with dynamic characteristics, including a curved ventilation channel that directs airflow and dust particles toward the collection area. The structure allows for easy disassembly and reassembly, enabling users to clean or replace the dust collection structure body whenever needed. This dynamic design reduces replacement frequency by making maintenance simple and straightforward, while maintaining effective dust adsorption capability.
Solution Approach 2:
The dust collection structure body is designed to be discarded (removed) when heavily contaminated with dust, and can be recovered (cleaned or replaced) as a simple, inexpensive component. This approach is more economical than replacing the entire ventilation system. The dust collection structure body can be easily removed for cleaning or replacement, reducing the time and cost associated with maintenance while maintaining effective dust adsorption.
3Reliability
If substances such as activated carbon are added to filter cloth, then filtration effect is enhanced, but the complexity and cost of the filtration system increases
Solution Approach 1:
The complex filtration function is extracted into a separate, dedicated dust collection structure body that can be easily removed and replaced. This dedicated structure handles all filtration functions including dust adsorption, eliminating the need to incorporate multiple substances like activated carbon directly into the filter cloth. The extraction principle simplifies the overall system by separating the filtration function from the structural components, reducing complexity while maintaining effective filtration.
Solution Approach 2:
The dust collection structure body is designed as an inexpensive, easily replaceable component that can be discarded when worn or contaminated. This approach eliminates the need for complex, expensive filtration materials like activated carbon embedded in filter cloth. The simple, inexpensive dust collection structure body provides effective filtration through its geometric design and airflow dynamics, reducing both device complexity and cost while maintaining reliable dust adsorption capability.
