Traffic Signals TRIZ Cases

A collapsible marker uses a helical spring element to extend its body for high visibility and collapse it into a compact base.

Replacing volatile solvents with a solvent-free polyol system eliminates toxic emissions while maintaining rapid ambient curing and strong substrate adhesion.

Ultrasonic vibration locally liquefies thermoplastic pavement marking sheets to form a strong bond, eliminating heated glue and reducing environmental impact.

A resilient stanchion supports a color-coded flag to mark underground fuel tank filler ports and convey fuel attributes.

Segmented mounting posts use asymmetric protrusions to snap onto traffic cones, resolving the trade-off between easy assembly and rotational stability.
