Traffic Signals TRIZ Cases

Bonded pillars strengthen high-stress rim flange areas of a single-walled plastic traffic delineator barrel, reducing crack susceptibility during handling.

Pre-magnetized magnetic markers eliminate on-site polarity checks, reducing installation costs while maintaining driving assist reliability.

An automated rumble strip assembly uses sensor-detected vehicle presence to raise and lower elongate members within a frame.

A dynamic percussion device uses a movable striker to tilt and transport traffic cones via vehicle kinetic energy.

A clamping device with adjustable jaws secures receiving tubes on guardrail posts.

Clear polycarbonate cover shields reflective sheeting from vehicle impacts while a stiffening element restores marker position.

Elastic rods force the hollow body to deploy instantly, reducing responder exposure to high-speed traffic hazards.

An adhesive agent binds microsphere lenses inside cavities of a protruding core, preventing detachment and bead cracking under stress.

An impact resisting post uses an inverted hook member to absorb vehicle collision energy through controlled elastic deformation.

Side-mounted reflective elongate bodies improve motorist visibility in adverse weather while eliminating worker exposure to live traffic during installation.

Porous silica replaces ion exchange resins to prevent discoloration while enabling thick, durable highway markings.

Segmented cover and retention components allow damaged lids to be swapped while keeping the embedded sleeve in place, cutting repair labor.

Embedded metal plates in flexible polymeric rumble strips provide ballast to maintain position under heavy traffic without adhesives.
