Traffic Signals TRIZ Cases

Nested post segments reduce storage volume while maintaining deployed stability, resolving the trade-off between adaptability and space.

A foundation pile design integrates a circumferential member with the central axis to reinforce the upper side circumference.

Pre-formed slots allow rapid sign attachment via slideable bolts, eliminating drilling risks and preserving barrier stackability.

Recycled rubber powder fillers enhance polymer viscosity for extrusion, resolving high costs and environmental waste from virgin materials.

Remote-controlled spike snares deploy from a speed bump to immobilize vehicles while allowing safe passage for other traffic.

A self-illuminating head powers light sources via a solar panel, ensuring visibility for cyclists and pedestrians without replacing existing posts.

Composite rigid and elastomeric components resolve durability versus flexibility trade-offs, allowing markers to recover upright after straddle hits.

Infrared retroreflective spheres embedded in paint resolve the contradiction between human visual clutter and automated vehicle detection accuracy.

PP/PE copolymer thermoplastic markings resist alkaline concrete degradation, preserving retroreflectivity and adhesion where PA/EVA materials fail.

A laminated roofing product combines sheets with varying recycled material content to balance stiffness and flexibility.

A mobile dispenser uses a curved track conveyor to transfer barrier beacons, eliminating personnel exposure to traffic lanes.

A safety marker integrates a battery-powered convection fan to accelerate liquid evaporation on adjacent surfaces.

Zirconia alumina silica microspheres improve retroreflectivity and durability while minimizing material costs.
