Radiation Protection TRIZ Cases
- Boron Medicament Feed Path Through Shielding Doors in Neutron Therapy
A partition-wall feed path bypasses the shielding door to keep boron medicament flowing during neutron capture therapy while limiting neutron exposure.
- Double-Containment Personnel Gate with Synchronized Sealing Doors
A shell ring, dual sealing doors, and a transmission cartridge cut leakage, improve door synchronization, and simplify nuclear gate installation.
- Medicament Supply Routing Through Shielding Partitions for Neutron Therapy
A slotted partition and containing mechanism let medicament bypass the shielding door, maintaining continuous delivery while reducing neutron exposure.
- Low-E Coated Article with NiCr and Silicon Nitride Layers
Silver, nickel chromium, and silicon nitride layers maintain low visible transmission and color stability after heat treatment.
- Magneto-rheological Panel Assembly for Localized Transmissivity Control
Transparent panel assembly with embedded electromagnets manipulates magneto-rheological fluid to adjust radiation transmissivity.
- Pneumatic RF Shielding Door for HEMP Protection
Inflatable air seals create conductive paths between stainless steel door and frame to block radio frequency transmission.
- MRI Shielded Door With Cam Surface and Rod-less Cylinder
Cam surfaces constrain doors to single-plane motion, enabling rod-less cylinders to actuate sealing fingers that maintain EMF-free MRI environments.
- Combined Cell and Container Door Opening Mechanism
A combined opening mechanism synchronizes cell and container doors using a pivoting lever and spring system to maintain secure alignment.
- X-ray Shield With Moveable Support Bar For C-arm Collision Avoidance
A moveable second support bar on an X-ray shield adapts to C-arm movements.
- Fluidtight Fire Door Thermal Insulation Segmentation
Segmented thermal insulation layers with a middle heat-absorbing layer limit unexposed side temperature rises to meet ELI standards.
- Multi-pane Glazing Unit with Varying Gap Width for RF Transmission
A multi-pane glazing unit uses varying gap widths between glass panes to enable radio frequency signal transmission.
- Radiation Protection Slat Arrangement with Hinged Overlapping Design
Segmented slats rotate and overlap to prevent leakage while maintaining simple carrier complexity.
- Metal Door RF Shielding Composite Layers
Zinc and copper layers fuse to steel door surfaces, achieving 40 dB RF attenuation while maintaining STC ratings.
