Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large-sized isolation device is used to contain bio-aerosol exposure equipment, then aerosol leakage prevention is improved, but the device size and weight increase, making it difficult to adapt to different installation sites
Solution Approach 1:
The isolation device is divided into a fixed support frame and a flexible cabin body that can be independently assembled and disassembled. The cabin body includes separate functional modules (work area, storage area, control area) that can be configured according to different installation sites, reducing the need for a single large rigid structure while maintaining effective aerosol containment through the sealed flexible enclosure.
2Ease of operation
If a large sealing door is arranged at the bottom of the isolation device for equipment access, then operational accessibility is improved, but the device complexity and sealing requirements increase
Solution Approach 1:
The isolation device uses a flexible cabin body with zippered or roll-up access points instead of large fixed sealing doors. These dynamic access points can be opened only when needed and maintain sealing when closed, eliminating the need for complex large door mechanisms while preserving equipment access capability through the flexible enclosure walls.
3Adaptability or versatility
If various operation interfaces are provided on the isolation device for test operations, then operational flexibility is improved, but the device complexity increases
Solution Approach 1:
The isolation device incorporates a universal control system with a touchscreen display and standardized control interfaces that can manage multiple functions (aerosol generation, animal monitoring, environmental control, data collection) through a single integrated panel. This multi-functional interface reduces the need for separate specialized controls for each operation, maintaining versatility while simplifying the overall device structure.

Function Achieved in This Case
This design allows for flexible assembly and disassembly, easy transportation, and effective aerosol containment, ensuring operator safety and preventing environmental pollution by enabling flexible operation in various environments and improving motion range during bio-aerosol exposure tests.
Implementation Method 1
The HEPA filter is mounted in the filter box body, and is configured for efficiently filtering environment air to be delivered into the protective half suit
Implementation Method 2
the air supply filter device is communicated with an interior of the protective half suit through an air pipe, and inflates the protective half suit by air with a positive pressure
Implementation Method 3
The air inlet device and an air exhaust device, arranged on a side wall of the cabin body... create a negative pressure environment for safe operation and personnel protection
