Regional Suction Control for Dynamic Cleanroom Decontamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decontamination methods for cleanrooms are not suitable for spaces with changing occupancy, as they are designed to minimize human presence, making it inefficient and costly to maintain air purity in areas with frequent human interaction.
Innovation Solution
The method involves dividing a room into regions of use and non-use areas, with suction means assigned to each region based on expected use intensity, using targeted airflow and air supply to efficiently remove contaminants and prevent cross-contamination, and adjusting suction and air supply parameters dynamically to match usage patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If decontamination measures are continuously carried out in a room with high human occupancy, then air purity is improved, but operational costs and energy consumption increase
Solution Approach 1:
The room is divided into multiple regions of use with different contamination risks. Suction means are selectively activated only in regions where people are present, rather than continuously operating throughout the entire room. This segmentation allows decontamination measures to be applied locally and only when needed, reducing overall energy consumption while maintaining air purity in occupied areas.
Solution Approach 2:
The system dynamically adjusts the operation of suction means based on real-time detection of human presence in different regions. When people are detected in a region, suction is activated; when regions are unoccupied, suction is reduced or stopped. This dynamic adaptation enables the system to maintain air purity during high-occupancy periods while minimizing energy consumption during low-occupancy periods.
2Object-affected harmful factors
If suction capacity is increased to handle high human occupancy, then contamination risk is reduced, but device complexity and cost increase
Solution Approach 1:
Instead of using a single high-capacity suction system that would require complex control mechanisms, the patent divides the space into multiple regions, each with its own suction means. This allows the system to achieve high overall contamination protection by coordinating multiple simpler, lower-capacity suction units, thereby reducing individual device complexity while maintaining effective coverage.
Solution Approach 2:
Each region is equipped with suction capacity appropriate to its specific contamination risk level and occupancy pattern, rather than uniformly high capacity throughout. This localized approach ensures adequate protection in high-risk areas while avoiding unnecessary complexity and cost in low-risk areas, optimizing the overall system design.
3Productivity
If the room is divided into multiple regions with individual suction means, then decontamination efficiency is improved, but device complexity increases
Solution Approach 1:
Multiple suction means are controlled by a centralized control unit that coordinates their operation based on detected human presence patterns. This merging of control functions allows the system to manage multiple regional suction units efficiently, achieving high decontamination productivity through coordinated operation while avoiding the complexity of entirely independent control systems for each suction unit.

AI summary
A method for preparing decontamination measures within a room located in a building and used by people includes a planning acquisition step. Therein, a plurality of regions of use within the room are identified, and for each region an expected use intensity is determined based on previously determined parameters. In a subsequent planning implementation step, for each region of use, proceeding from the expected use intensity, a suction means assigned to said region of use and having an associated supply air volume flow is specified. In a method by carrying out the decontamination measures, while the decontamination measures are being carried out, operation of individual suction means is adjusted to an actual use of the assigned region of use by people, and a suction volume flow suctioned by the suction means in question is specified, between a minimum value specified for the suction means in question, and a maximum value.
