Gasproof Doors TRIZ Cases
- Method of controlling a flow of air through a door
See how a hollow core door with center panel notches enables non-linear airflow to prevent room
- Hollow core door with perimeter air flow and multiple damper panels
See how a hollow core door uses perimeter air flow and movable damper panels to prevent pressur
- Hollow Core Door with Perimeter Airflow to Prevent Pressure Buildup
See how a hollow core door uses non-linear perimeter airflow and absorbent materials to prevent
- Hollow Core Door Sliding Panels for Air Pressure and Gas Absorption
Aligned panel openings equalize room pressure, while diatomaceous earth and gypsum absorb formaldehyde in the hollow core.
- Hollow Core Door Venting for Pressure Equalization and Air Scrubbing
Offset internal openings let air pass through a hollow core door to relieve room pressure while absorbent material removes formaldehyde and noxious gases.
- Hollow-Core Stile and Rail Door for Perimeter Airflow Venting
Nonlinear airflow through hollow stiles and rails relieves room pressure buildup while absorbent core materials remove formaldehyde gases.
- Margin Airflow Door Structure for Room Pressure Relief
Non-linear airflow through door margins relieves closed-room pressure buildup while absorbent core materials help remove formaldehyde and noxious gases.
- Hollow Core Door Airflow Layout for Pressure Relief and Formaldehyde Capture
Offset airflow passages and absorbent core materials relieve room pressure buildup while capturing formaldehyde in hollow core doors.
- Hollow Core Door Air Scrubbing for Formaldehyde Removal
Absorbent and photocatalytic materials inside a hollow core door use vertical airflow to remove formaldehyde and other indoor air contaminants.
- Hollow Core Door Airflow Structure for Pressure Relief and Privacy
Offset internal air passages relieve room pressure buildup while preserving privacy, and absorbent core materials help cut formaldehyde and VOCs.
- Adjustable Door Bulkhead Sealing for Negative-Pressure Dust Control
A length-adjustable door bulkhead uses sealed air passages and force-distributing clamps to maintain negative pressure without damaging door frames.
- Inflatable Chamber Lock for Negative-Pressure Containment
This case uses pneumatic inflation and negative pressure to replace wooden locks with reusable barriers for asbestos containment.
- Door Bulkhead with Adjustable Clamping and Air Passages
Gear-driven clamping distributes force via sealing elements to prevent frame damage, enabling negative pressure maintenance without tilting.
- Retractable Containment Barriers for NGV Service Area Segmentation
Segmented vinyl barriers isolate compressed natural gas handling areas, reducing facility upgrade complexity and costs while maintaining safety compliance.
