Portable Traffic Signalling TRIZ Cases

Damage alerts from a disabled self-driving vehicle trigger nearby autonomous vehicles to slow, reroute, and warn others around the hazard.

Moulding the base and reflector holder as one piece cuts parts and joints, improving V16 beacon reliability and production speed.

Acoustic-echo and LiDAR cone units detect vehicle intrusions early and propagate audible and visual alerts across roadway work zones.

A self-contained ADS-B tracker uses GPS and battery backup to keep distress position broadcasts accurate and continuous after power loss.

A sensor station detects approaching vehicles and transmits wireless signals to safety vests for immediate worker alerts.

Detection unit mounted on boundary markers uses the Doppler Effect to identify moving vehicles near work zones.

A wireless electronic flare system coordinates sequential flashing patterns to enhance driver visibility and simplify roadside deployment.

Blinking LEDs embedded in the paddle face attract distracted drivers at school crosswalks, resolving visibility issues without adding structural complexity.

Radar-triggered LED panels illuminate traffic signs only when vehicles approach, preventing driver habituation from continuous static lighting.

Dynamic geofencing segments alert zones by road geometry to eliminate unnecessary notifications for vehicles outside the travel path.

Wireless synchronization eliminates wire entanglement while sequential lighting reduces driver confusion from excessive light noise.

An integrated electronic sound device in a handheld sign handle replaces manual whistles, freeing operator hands and preventing germ spread.

Wireless transceivers employ chirp spread spectrum modulation to measure distance, alerting workers in noisy environments where conventional visual flags fail.

A vehicular incursion alert system uses distributed sensor nodes to detect vehicle entry into protected zones and trigger vehicle alarms.
