Modular Containment Enclosure for Virus Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biologics manufacturing, particularly the production of viruses or virus-derived products, requires expensive and risky bio-safety level 3 and 4 facilities due to the need for containment to prevent environmental contamination, which increases capital expenditure and operational complexity.
Innovation Solution
A containment enclosure system with a bioreactor, purification unit, inactivation unit, and gas decontamination unit, controlled by a process control device that ensures all production steps are completed and validated before allowing exit, reducing environmental contamination risks and enabling safer, more efficient production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If BSL-3 and BSL-4 facilities are used for virus production, then environmental contamination is prevented, but capital expenditure and operational complexity increase significantly
Solution Approach 1:
The system divides the containment facility into modular functional units (production unit, purification unit, inactivation unit, decontamination unit) that can be independently configured and operated. Each unit has specific containment functions, allowing high biosafety without requiring an entire complex facility to operate at BSL-3/4 level continuously.
Solution Approach 2:
The critical containment functions (inactivation, decontamination, monitoring) are extracted as dedicated separate units rather than being distributed throughout a large facility. The inactivation unit and decontamination unit are specifically designed to handle hazardous materials, concentrating safety functions in targeted locations rather than requiring entire buildings to be classified as BSL-3/4.
2Reliability
If BSL-3 and BSL-4 facilities are provided with contamination prevention means, then environmental safety is improved, but capital expenditure becomes extremely high
Solution Approach 1:
The system employs disposable single-use bioreactors and consumable decontamination cartridges that eliminate the need for expensive, permanent infrastructure. These single-use components provide adequate containment for their specific purpose and are discarded after use, avoiding massive capital investment in reusable BSL-3/4 facility infrastructure.
Solution Approach 2:
The system changes the containment approach from facility-level parameters (building classification, HVAC systems, pressure differentials) to process-level parameters (inactivation temperature, decontamination chemical concentration, validation protocols). This shifts expenditure from capital-intensive facility construction to operational process parameters that are more cost-effective.
3Reliability
If a process control device controls exit means access, then environmental contamination risk is reduced, but system complexity increases
Solution Approach 1:
The process control device continuously monitors the status of all production units and decontamination systems, and automatically controls the exit means based on real-time feedback. If any unit reports abnormal conditions or incomplete decontamination, the exit remains locked. This automated feedback loop provides high reliability without requiring complex human oversight systems.
Solution Approach 2:
The system performs self-validation through automated monitoring and interlocking. The process control device automatically verifies that all decontamination cycles are complete and all units are safe before permitting exit, eliminating the need for manual safety checks and reducing operational complexity despite increased automation.
4Reliability
If all production steps are performed in enclosed containment, then safety risks are highly reduced, but equipment size and cost increase
Solution Approach 1:
The system nests multiple functional units within a compact hierarchical structure. The production unit contains bioreactors, the purification unit contains filtration and chromatography systems, and the inactivation/decontamination units are integrated within the same enclosure. This nesting allows all containment functions to be performed in a much smaller footprint than traditional distributed BSL-3/4 facilities.
