Roads Maintainence TRIZ Cases

Construction management system calculates paving material weight supplied to an asphalt finisher using truck identification.

A sensor system combines tilt and yaw rate signals using a Kalman filter to produce an acceleration-compensated inclination signal.

A compaction system uses a force sensor at the articulated joint to measure propulsion force transmitted through the mechanism.

Laser sensors detect relative plate positions to automate paving adjustments, eliminating manual measurement errors.

A sealed distribution box uses a pneumatic pump to move dry binder mixtures through an ingress pipe and spreader bar for precise application.

Segmented beam and threaded connection enable single-operator flatness without cumbersome power units.

Controller adjusts pump rates by measuring emulsion mass and spray area to resolve contradictions between calibration complexity and application accuracy.

Segmented rigid and flexible conduits route hydraulic fluid through moving frames, preventing hose damage from tight bend radii.

An impact-resistant casing protects a concrete core in soil compactor weights, preventing breakage under load and ensuring operational continuity.

Segmented hand truck applicators resolve clogging contradictions by using adjustable nozzles to maintain uniform bonding on small asphalt areas.

Variable gap width between the milling drum and hold-down device reduces material compaction and power consumption during road milling operations.

Rotating drum with helical blades moves loose particulate material laterally across road surfaces to redistribute gravel and soil.

An integrated road marking cutter combines suction collection with vibration damping mechanisms to eliminate separate escort vehicles.

Elastic fastening device prevents over-tightening damage by applying a predetermined force to secure heating elements on paving screeds.

Molding a single plastic component for the handle, sprinkler, and fastener reduces manufacturing costs while maintaining ergonomic grip and secure attachment.

Automated heating and agitation prevent phase separation in stored emulsion oils, eliminating pump clogging and sludge buildup during extended storage periods.

A road paver material container features a viewing indentation in its rear wall and floor to provide an unobstructed operator view of the ground.

Overlapping flexible strips in a hopper enclosure dynamically adjust to conveyor misalignment, preventing material loss during transfer.

An adjustable cut material deflector eliminates manual repositioning steps by adapting its position to varying subsoil cover layer thicknesses.

Removable nozzle elements allow variable spacing, reducing clogging downtime and detergent use.

Multiple hole patterns on the chassis allow variable height positioning of worm gear bearings, eliminating costs from maintaining separate bearing arrangements.

High hydroxyl anti-aging agents reverse oxidation in reclaimed binders, enabling higher recycled material incorporation rates.

Segmented gates dynamically control material deposition to resolve bridging issues and maintain uniform compaction over irregular terrain.

Impact crushing reduces bitumen in coarse fractions, enabling high-temperature drying and 95% reuse without sticking.
