Liquid Fertiliser Distribution TRIZ Cases

A pivoting folding tongue shortens a PTO manure pump trailer for transport and tight positioning while avoiding long shaft complexity.

Dynamic axle extension and steering adjustment help agricultural sprayers match varying row widths while maintaining consistent product application.

Inertial sensor feedback and active torque control keep a spray boom aligned over uneven ground for uniform coverage and lower drift.

A pivot-and-slide tank lid keeps the compression seal off the flange during opening, improving fill access while limiting pollutant buildup.

Guides and sliding mechanisms move the tank lid clear of the flange without fouling the seal, reducing debris buildup and preserving closure under pressure.

Inertial sensors and active boom actuation maintain stable ground distance on uneven terrain, improving application uniformity and reducing drift.

Throttled passages and an overflow maintain block basin liquid level without valves, simplifying assembly and separating fresh and used liquid.

Front-mounted cameras detect field targets before spray dust obscures them, enabling real-time nozzle timing and precise material application.

When a work vehicle deviates from its route, it can stop, return automatically, and resume autonomous travel without manual intervention.

Remaining field area and onboard product amount are used to adjust application rates, reducing overuse and missed coverage.

Wind and field-boundary data guide a UAV to monitor likely drift zones and detect agricultural overspray in real time.

Secondary valves at the probe air inlet back up the primary valve to contain leaks and maintain a fluid-tight closed transfer coupler.

A throttled overflow distributor meters liquid into the tub area and drains excess flow, avoiding valves and electronic controllers.

Neighbor-based comparison of nozzle instruction and sensor scores detects spray outliers early and can trigger fallback broadcast spraying.

A passive overflow distributor throttles liquid into the tub area, replacing valves and controllers while keeping supply uniform and simple.

RF signal attenuation through atomized spray detects partial or full nozzle plugging with fewer false readings from noise, vibration, and dirt.

Real-time altitude adjustment based on propeller downwash and load changes helps maintain spray penetration while reducing crop collapse.

UAV-based drift sensing tracks wind and field boundaries to position sensors where overspray is likely and trigger real-time sprayer adjustment.

Boom-mounted cameras and processing monitor spray patterns, detect nozzle issues, and adjust application in real time for more uniform fluid distribution.

Boom-mounted cameras, lights, and image differencing track spray patterns in real time to control nozzle PWM, detect drift, and reduce waste.

Cameras with mixed fields of view track spray patterns in real time, enabling AI-based nozzle adjustment to detect plugging, drift, and uneven distribution.

Speed-based phase and subgroup valve delays keep boom pressure and electrical demand stable while maintaining continuous spray coverage.

Speed-based phase and subgroup delays stagger nozzle valves to preserve spray coverage while avoiding pressure drops and power surges.

Movable frames keep injectors synchronized with ground motion, enabling lower-energy subsurface carbon injection with minimal surface disruption.

Supplying Sphagnum with nitrogen, phosphorus, and/or potassium through irrigation can improve growth while reducing water use and site infrastructure.

Hydraulic damping helps an agricultural applicator’s breakaway boom manage obstacle contact, force, and return speed.

Speed and position sensors guide PID boom adjustments as sprayer speed and terrain change, keeping spray height and coverage uniform.

A pumped parallel circuit replaces large gravity pipelines, delivering consistent nutrients and enabling faster pH adjustments.

This case uses an existing-mount protective cover to deflect plant residue and protect fertilizer tubes during no-till planting.

A movable rail positions aligned spray nozzles for scalable ground printing, reducing pre-planning and manual marking work.

Motorized rotary sprinkler heads adjust flow and angle to eliminate water waste from inaccurate irrigation schedules.
