Solution Overview
Problem
Conventional process simulation tests in clean rooms require separate facilities for concurrent product production, leading to inefficiencies and increased contamination risks due to personnel movement between clean rooms with varying cleanliness levels.
Innovation Solution
A facility with a clean room containing multiple work booths equipped with barrier sections that maintain the same cleanliness level inside and outside, allowing parallel manufacturing and simulation tests without changing clothes, using positive pressure generators to prevent airflow contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple clean rooms are used to concurrently perform process simulation tests and product production, then productivity is improved, but device complexity and contamination risk increase
Solution Approach 1:
The clean room is segmented into multiple independent work booths, each capable of performing different operations (manufacturing or simulation) simultaneously. This segmentation allows concurrent operations within a single controlled environment, achieving the productivity benefits of multiple clean rooms while maintaining a single controlled space to reduce contamination risk and simplify facility management.
Solution Approach 2:
Multiple work functions (manufacturing and simulation testing) are merged into a single clean room through the use of multiple work booths. This combining approach allows concurrent operations to occur in one facility rather than requiring separate clean rooms, thereby improving space utilization and reducing the complexity associated with managing multiple independent clean room environments.
2Productivity
If workers move between clean rooms with varying cleanliness levels, then productivity is maintained, but contamination risk increases
Solution Approach 1:
All work booths within the clean room are maintained at the same cleanliness level (e.g., Class 10,000), creating an equipotential environment regarding air quality. This eliminates the contamination risk associated with workers moving between areas of different cleanliness levels, as no decontamination procedures or clothing changes are required when transitioning between work booths, thereby maintaining worker mobility and productivity.
3Reliability
If workers change clothes according to cleanliness levels, then contamination is prevented, but productivity decreases
Solution Approach 1:
By maintaining uniform cleanliness levels across all work booths, the need for workers to change clothes when moving between different cleanliness zones is eliminated. Workers can move freely between work booths without undergoing time-consuming decontamination procedures or clothing changes, thereby preventing contamination while maintaining high productivity.
4Reliability
If barrier sections prevent airflow from outside to inside work booths, then cleanliness is maintained, but device complexity increases
Solution Approach 1:
Barrier sections utilize pneumatic principles by controlling airflow patterns and pressure differentials to prevent contamination. Air curtains or positive pressure systems create invisible pneumatic barriers that block the passage of particles and microorganisms without requiring physical partitions or doors, thereby maintaining cleanliness while minimizing structural complexity.
