Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purification systems face inefficiencies due to limited interaction between air flowing through the system and the biological agent, leading to inadequate air purification.
Innovation Solution
The air purification system incorporates a housing with a fan, pump, and controller, featuring multiple interaction surfaces such as screens positioned vertically within the housing. The system sprays a biological solution, mixed with water, onto these surfaces, enhancing interaction with airflow to remove impurities electrostatically and biologically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single interaction surface is used between biological agent and airflow, then the device complexity is reduced, but the air purification efficiency deteriorates due to limited interaction
Solution Approach 1:
The interaction surface is segmented into multiple screens (first screen, second screen, third screen) arranged in series within the housing. Each screen provides a separate interaction zone where biological agent can contact airflow, thereby increasing overall purification efficiency while maintaining manageable device complexity through modular segmentation
Solution Approach 2:
The screens are arranged in a multi-dimensional configuration within the housing space, creating multiple interaction zones along the airflow path. This spatial arrangement increases the effective interaction surface area without proportionally increasing device footprint, resolving the contradiction between purification efficiency and device complexity
2Productivity
If multiple interaction surfaces are added to increase biological agent interaction, then air purification efficiency is improved, but the device complexity increases
Solution Approach 1:
Each screen serves multiple functions: it acts as a support structure for biological agent, creates turbulence to enhance mixing, and defines interaction zones. This multi-functionality allows multiple interaction surfaces to be achieved without proportionally increasing device complexity, as each component performs several roles simultaneously
Solution Approach 2:
The multiple screens are nested within the housing in a compact arrangement, with each screen positioned within the flow path of the previous one. This nested configuration maximizes the interaction surface area within a compact device footprint, improving purification efficiency while controlling overall device complexity
3Volume of moving object
If the housing size is reduced to make the device compact, then the portability is improved, but the interaction surface area for air purification is reduced
Solution Approach 1:
The interaction surfaces are arranged in a three-dimensional configuration within the compact housing, with screens positioned at different depths and angles along the airflow path. This vertical and spatial arrangement maximizes the effective interaction surface area within a minimized horizontal footprint, resolving the contradiction between compact size and interaction surface area
Solution Approach 2:
The screens are configured with curved or angled surfaces rather than flat planes, allowing them to interact with airflow from multiple directions within the compact housing. This curvature increases the effective interaction surface area without increasing the housing volume, as the curved surfaces utilize the available three-dimensional space more efficiently
