Traffic Restrictions TRIZ Cases
- Hand-Held Barrier Apparatus with Extendable Loop
A hand-held barrier apparatus uses an extendable longitudinal element and connectors to form secure loops around base supports.
- Deployable Traffic Barrier With Friction Mat
A deployable barrier system uses a sliding friction mat to resist vehicle impact.
- Counterweight Beam Gate for Vehicular Traffic Control
A counterweight beam gate mechanism raises and lowers a hollow barrier to manage vehicular traffic flow.
- Buried Bollard Barrier with Mechanical Linkage
A buried vehicle security barrier uses a mechanical linkage to move one bollard between two fixed units for access control.
- Parking Barrier Base System with Flexible Anchoring
A parking barrier base system uses flexible connections to anchor hoop ends directly to asphalt surfaces without concrete pads.
- Chain Barrier Safety Device with Movable Detection Element
A chain barrier safety device replaces optical sensors with a mechanical detection system that stops the chain upon detecting trapped objects.
- Friction-Enhanced Vehicle Barrier with Stabilizer Beam
Segmented horizontal and vertical components enable rapid deployment while the stabilizer beam prevents rotation, resolving complexity trade-offs.
- Compact Retractable Bollard with Horizontal Counterweight
Horizontal counterweights reduce installation footprints for buried cable areas while maintaining shock resistance.
- Rotating Barrier System with Sliding Friction Turntable
A rotatable barrier system uses a worm gear drive to rotate a heavy counterweight on a sliding surface.
- Reusable Vehicle Spike Strip with Removable Spikes
Segmented housings hold removable spikes, enabling reuse and eliminating foam destruction during deployment.
- Self-Deploying Vehicle Barrier Using Impact Force
A self-deploying vehicle barrier converts incoming kinetic energy into mechanical deployment motion.
- Vehicle Barrier Beam with Pivoting Connections
Interconnected steel beams pivot to absorb impact forces, limiting vehicle penetration distance.
- Post and Beam Vehicle Barrier Pinned Connections
Segmented pinned joints allow vertical movement to resist vehicle penetration while maintaining structural integrity.
- Shallow-Mount Security Bollard Base with Interconnected Panels
A shallow-mount security bollard base uses interconnected welded panels to anchor the post securely.
- Remotely Deployed Spike Strip with Retractable Housing
Remote signals actuate the mover to expose spikes, enabling safe law enforcement deployment without manual roadside risks.
