Clean Room Air Guiding Layout for Low-Turbulence Aseptic Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clean rooms, particularly those used in medical product production, face contamination issues due to turbulent air flows generated by laminar air flows interacting with production equipment and surfaces, leading to the whirlup of dirt particles and germs.
Innovation Solution
The implementation of an air guiding device with elements that divert low-turbulence air flows around production areas and facilities, preventing direct contact and minimizing turbulence, using smooth, strategically placed air guiding elements made of sheet metal or other materials to shield these areas from the air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If laminar air flow is introduced into the clean room area, then the risk of dirt particles or germs entering is reduced, but turbulent air flows are generated due to impact with technical equipment and work surfaces
Solution Approach 1:
Air guiding elements are introduced as intermediary components between the air flow and production equipment. These elements redirect the air flow paths so that the air flow bypasses technical equipment and work surfaces, preventing direct impact while maintaining the protective function of the air flow system.
Solution Approach 2:
The air flow system is segmented into multiple paths by introducing air guiding elements. Instead of a single direct air flow path, the system creates multiple redirected paths that navigate around production equipment, thereby maintaining laminar flow characteristics while avoiding turbulence-generating obstacles.
2Reliability
If air flow is directed through the clean room from ceiling to floor, then contamination is minimized, but direct impact with production facilities causes dirt particles to be whirled up
Solution Approach 1:
Air guiding elements serve as mediators that intercept and redirect the downward air flow before it can directly impact production facilities. This prevents the air flow from picking up dirt particles from equipment surfaces while maintaining the overall downward flow direction for contamination control.
Solution Approach 2:
The air flow path is modified by adding lateral redirection components. Instead of purely vertical flow, the air guiding elements introduce horizontal or angled flow components that guide air around production facilities in three-dimensional space, preventing direct impact while maintaining flow continuity.
