Roads Maintainence TRIZ Cases

Optical sensors detect paving material levels to independently adjust left and right auger speeds, reducing manual intervention.

Segmenting the vibrating mass via intermediary isolators increases vibrational amplitude and reduces screed deformation.

Segmented alignment phases reduce mounting time by guiding the milling unit with wedge surfaces before engaging fastening screws.

Analytics platform uses sensor filters to classify potholes, resolving manual identification bottlenecks and improving response speed.

Polygonal walls and tubular breakers tumble asphalt while expansion joints accommodate thermal stress to prevent sticking.

A road paver screed plate uses a single temperature sensor to adjust heating element targets based on thermal time profiles.

Laser sensors detect reference elements on moving units to adjust the feed conveyor, resolving misalignment issues during automated material transfer.

Controller moves screed extension plate based on sensor data mounted on a stable chassis reference frame to reduce transition marks.

Fixed claws absorb weight and reaction forces to eliminate continuous hydraulic pressure and prevent toppling during slipforming.

Segmented gearbox housing with a radial recess relocates the reduction gear outside the milling drum, preventing material blockage and wear in narrow gaps.

A controller manages the transport conveyor slewing angle to discharge milled material onto a vehicle.

A mobile planing machine injects bitumen emulsions into milling tools to agglomerate dust with millings.

A milling drum with independently controllable zones adjusts depth to remove only necessary road material.

A bracket assembly with a sliding mechanism extends a lifting point along a rigid frame.

A separate pavement edge forming member uses an inclined shaping plate to create a ramped surface, preventing screed extension interference.

A control unit monitors edge protector height and lowering speed to automatically adjust position via a lifting device.

A rotatable spool assembly winds used temporary tape while the machine moves along pavement.

Angled stereo cameras overlap their fields of view to eliminate vehicle body interference, expanding the measurement range while maintaining precision.

Eccentric shaft generates vibrations to compact asphalt, preventing premature repair failure from insufficient density.

Movable and pivoting channel plates adjust effective width to prevent material overflow during road finishing operations.

Incorporating 50 to 70 percent sulfur into polyvinyl acetate raises the melting point by 10 to 50 degrees while improving ductility.
