Road Cleaning TRIZ Cases

Rotatable panels mediate between the user and waste, resolving the contradiction between ease of operation and reliability for semi-solid pickup.

A removable fan assembly mounted in a refuse vehicle hopper gathers leaves via an articulated boom, eliminating the need for dedicated collection fleets.

Spring claws and a magnet enable efficient object retrieval, reducing user fatigue caused by continuous handle actuation.

A weeding arm with a rotating brush connects to a suction hose to collect plant debris during mechanical removal.

Intercooler extracts heat from accelerated micro-spheres to prevent bitumen reactivation during high-speed shotpeening.

An integrated pet waste dispenser combines illumination and a pivoting scooper to resolve the trade-off between device complexity and ease of operation.

Onboard flocculation and sedimentation stages purify contaminated washing liquid, eliminating tanker truck logistics and reducing fresh water consumption.

A snow removal assembly positions a power broom ahead of vehicle wheels to sweep thin snow layers before compaction occurs.

A fixing device with contact areas and a tensioning mechanism secures floor treatment tools on the traveling frame.

A self-propelled road cleaning machine integrates a rotating sweeper brush and scrapper blade assembly for simultaneous debris removal.

Nested hooks and a V-shaped support member secure bags automatically, resolving sanitation reliability issues for elderly users.

Spring-biased jaws grasp and lock pet waste to eliminate direct hand contact during collection.

A feces collection holder uses a ring groove and compressible gasket to secure a plastic bag open without direct user contact.

A pet waste tool uses tines to lift droppings and a plate to sweep them into a container.

Segmenting the suction nozzle into a fixed base and sliding adapter resolves adaptability versus reliability trade-offs in multi-purpose vacuum vehicles.

Segmented air knives with pivotable frames maintain consistent surface contact while clearing debris and drying roads.

Dual motorized clamps secure a fabric bag over waste, eliminating manual contact and bending.

Dual hydraulic piston-cylinder groups with bypass valves allow the brush to drop sharply over bumps, restoring immediate ground contact.

Convex curvature and replaceable inserts reduce wear on uneven surfaces while maintaining structural strength.

A remotely controlled spreader uses rotating blades to distribute salt or fertilizer across lawns and driveways.

Spring-actuated jaws open automatically to collect dog waste, eliminating unsanitary manual handling.

Automated deflecting elements remove debris accumulation that causes incorrect depth measurements, restoring productivity.

A self-propelled maintenance device autonomously redistributes infill material across artificial grass sports fields using pre-programmed control plans.

A disposable pet waste kit uses a nested scoop and bag structure to enable one-handed collection.

A pooper scooper uses a tab-into-slot locking mechanism to seal waste inside a disposable cardboard cartridge, eliminating direct hand contact during disposal.
