Solution Overview
Problem
Existing aerosol capture devices face challenges in concentrating aerosols effectively due to the large volume of capture liquid, leading to low aerosol concentration and inefficiency in capturing harmful particles like fine dust, mold, bacteria, and viruses.
Innovation Solution
The aerosol capture device incorporates a housing with an air inlet and discharge part, a capture liquid, and a concentration part that includes a guide part to enhance aerosol capture and concentration using a filter member, antibodies, magnetic beads, and electrodes to fix and separate aerosols from the air, allowing for efficient concentration and discharge of the capture liquid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large volume of capture liquid is used to capture aerosols, then the capture efficiency is improved, but the aerosol concentration in the capture liquid decreases
Solution Approach 1:
The device divides the housing into multiple compartments including a capture liquid storage chamber, a capture chamber, and a concentration chamber. This segmentation allows the capture liquid to be used efficiently while concentrating aerosols in a separate chamber, resolving the contradiction between using sufficient capture liquid volume and achieving high aerosol concentration.
Solution Approach 2:
A concentration part acts as an intermediary between the capture liquid and the final aerosol concentrate. This intermediary component transfers and concentrates aerosols from the dilute capture liquid into a concentrated form, enabling both high capture efficiency with adequate liquid volume and high final aerosol concentration.
2Reliability
If capture liquid is continuously circulated to maintain aerosol capture, then the capture efficiency is maintained, but the capture liquid requires frequent replacement due to aerosol accumulation
Solution Approach 1:
The concentration chamber extracts and removes accumulated aerosols from the capture liquid. By continuously concentrating aerosols separately from the bulk capture liquid, the system maintains capture efficiency while preventing the capture liquid from becoming saturated, thereby reducing the frequency of liquid replacement and minimizing waste.
Solution Approach 2:
The system recycles the capture liquid by continuously concentrating aerosols in a separate chamber. The capture liquid is discarded minimally while the aerosols are recovered in concentrated form, transforming a waste problem into a resource recovery solution that maintains continuous capture efficiency.
3Device complexity
If the housing structure is simplified to reduce device complexity, then the manufacturing cost decreases, but the aerosol concentration function is compromised
Solution Approach 1:
The concentration part is integrated into the housing structure as a unified component rather than a separate external device. The housing serves multiple functions including capture liquid storage, aerosol capture, and aerosol concentration, merging these functions into a single integrated structure that reduces overall device complexity while maintaining concentration capability.
Solution Approach 2:
The housing structure performs multiple functions: it contains the capture liquid, facilitates aerosol capture, and enables aerosol concentration through the integrated concentration part. This multi-functional design eliminates the need for separate structures for each function, reducing device complexity while preserving the aerosol concentration capability.
