Gates/Doors TRIZ Cases

An automated pivotable barrier arm with a fan assembly prevents projectile accidents in MRI rooms without isolating the space or blocking communication.

Angled roller channel sidewalls reduce contact area, lowering friction and wear on cantilever gate frames while maintaining positioning stability.

Kit frame uses elastic snap-fit joints to eliminate welding costs and oxidation marks while allowing compact transport.

A sliding door arrangement uses modular units and cross rod assemblies to enable quick on-site construction.

Segmented doors and automatic latches resolve the trade-off between large door size and operator accessibility in collapsible exercise pens.

Interlocking bumps and grooves in the connecting piece resolve construction time and labor bottlenecks while ensuring structural firmness.

A retractable soft barrier uses flexible sheeting tensioned between adjustable support members to adapt quickly to varying spatial requirements.

Integrated light sources in transparent windows direct beams toward faces, preventing reflections and hotspots that obscure security team visibility.

Segmented antennas and curved absorbers determine RFID tag location, resolving detection reliability versus device complexity.

Nested stiffeners within uprights and sandwiched horizontal members prevent twisting, eliminating welding complexity during field assembly.

Segmented locking elements prevent rotation in receptacles, securing tension without special tools.

Beveled crossbar ends extend into recesses of upper and lower chords to prevent joint loosening under dynamic loads.

Automated hinged gates lock during wave generation to prevent water spillage and maintain consistent surf conditions.

A controller system manages shotgun gate movement by identifying ride vehicle row status to open or close gates independently.

A sliding wire door assembly eliminates swing space requirements and prevents object damage by moving horizontally along guide wires.

A door lock uses a wire rope and pull handle to operate the mechanical bolt without complex mounting structures.
