A nested metal outer vase and removable insert use a locking base to prevent memorial vase theft while preserving flower display.

Peg-secured outer and inner sculpture pieces create a stable ceremonial unity symbol while simplifying alignment during assembly.

A locking sleeve and telescopic hanging rod let flags or posters mount securely, then retract to avoid post damage and visible hardware.

A nested metal vase with a removable insert and locking base secures grave memorial flowers while preventing theft and vandalism.

Layered roofing balances high recycled content with a more flexible sheet to cut asphalt use while preserving impact resistance and handling durability.

A rotating claw and retention member separates, deploys, and collects road cones without mode reconfiguration, reducing complexity and roadside risk.

A flexible cover and plunger-driven ratchet gear convert vehicle impact into electricity while reducing speed bump size and mechanism complexity.

A 2D magnetic marker area plus orientation signs lets vehicles read road information reliably from different entry directions.

A single-piece polymer structure uses layers with different mechanical properties to absorb impact without joined-material separation.

Flexible wings and a shaped retainer let barrier tape release outward with less force than post toppling, enabling safer emergency exit.

Two boring drills, inertial navigation, and positioning sensors place road magnetic markers at fixed spacing without repeated cart repositioning.

Portable warning strip segments use jigsaw joints, recycled rubber, and metal reinforcement to speed setup while staying stable on uneven roads.

A hydraulic rotating impact attenuator helps a mobile emergency barrier absorb and redirect vehicle impacts in multi-lane incidents.

Integral hills and recesses let identical support bases stack and interlock, improving sign and barrier stability without extra couplers.

Flexible sides, recessed channels, and notches help a traffic director resist wind and impact while giving clearer directional cues.

High-speed grinding with a main drum and bevel cutters forms periodic road markings with smooth bases, clean edges, and lower paint use.

A T-post, spaced brackets, and a removable cover create a visible bollard look without concrete, cutting installation time and cost.

Impact-sensing road cones wirelessly trigger wearable audio, visual, and haptic alerts to warn workers of errant vehicles.

A dry polymer modified cement overlay creates durable pavement markings that resist traffic wear, weathering, and thermal mismatch while supporting retroreflective beads.

A compressible sleeve and lever arm apply even high clamping force to retain posts without side-bolt damage, twisting, or hard removal.

Rotating stacked legs let first responders carry a compact barricade, then quickly expand it for greater footprint, visibility, and stability.

High-intensity LEDs and a removable cordless-tool battery keep STOP/GO traffic signs visible and in service without recharge downtime.

An elastomeric retention link and rigid sacrifice link let a signpost yield on impact, reduce vehicle damage, and stay serviceable until replacement.

A sloped recessed reflector preserves road-marker visibility while deflecting wheel impacts to improve durability and service life.

A spring-mounted reflector and glass-fiber polymer support absorb frontal and lateral impacts, cutting delineator damage and maintenance.

A retaining and detaching tool places road magnetic markers with stable orientation, improving installation accuracy without slowing work.

Pivoting barrier and side arms fold into a compact stack, then lock open with spiked ends to deliver rapid vehicle barrier deployment.

An inflatable shutter surface extends or retracts by sensed vehicle speed to smooth traffic calming and reduce harsh braking and acceleration.

A fluid-filled road hump changes viscosity on impact, letting slow vehicles pass smoothly while resisting high-speed traffic without electronics.

A zippered reflective pole wrap with integrated LEDs retrofits existing traffic signs to improve noticeability and driver compliance.

Hydraulic impact attenuators and planar side skins help a mobile emergency barrier redirect crashes, absorb energy, and prevent entanglement.

Removable indicator sleeves add clear directional cues to a flexible, stackable traffic director that improves durability, stability, and storage.

A calcium aluminate and polymer cement mix creates durable pavement overlays that bond well and become traffic-ready within minutes.

Flexible luminous emitters embedded in roadway filler avoid duct cracking, support complex layouts, and stay visible in bad weather.

A modular kick-bar support assembly enables shallow bollard embedment while maintaining vehicle impact resistance and reducing excavation.
