Sowing TRIZ Cases

A cam-actuated sliding connector locks air lines without tools, reducing leakage, corrosion, and connection time in air seeder systems.

A polymer elbow with an embedded wear plate redirects abrasive fertilizer flow, resisting corrosion and reducing transfer-line wear.

Duty cycle from optical seed sensors is used to estimate particle frequency and flow rate, improving accuracy for high-flow crops without larger sensors.

Path interference estimation creates local exclusion zones so planters avoid overlap, reduce seed waste, and protect yield in buffer areas.

Optical speed sensing and a conical obturator keep granular solids in stable column flow while detecting plugging or empty conditions.

Remote sensing and local field sensors guide zone-specific dosing of crop inputs, cutting waste and resistance risk while supporting yield.

Combining satellite imagery with local field sensors enables precise, site-specific application of nutrients and crop protection agents.

Electronic pressure and flow compensator valves regulate swash plate output from the highest load pressure to reduce engine load and fuel use.

By estimating interference between planned planter passes, this case sets local exclusion zones to protect seeds and avoid wasted crop inputs.

Duty cycle analysis of ultrasonic seed sensors estimates particle flow in high-flow crops where optical counting becomes unreliable.

Timing signals trigger planting-machine image capture only at key events, reducing irrelevant frames and saving compute and storage.

Sensors detect seed arrival at each tool to calculate delivery delays, improving section timing and reducing over- or under-seeding.

A passive obstructive formation at the discharge opening deflects product flow to prevent bridging and keep mixer unloading uniform.

Integrated weight sensors automate bulk material meter calibration, cutting manual weighing time while improving dispensing accuracy.

A seeder door storage mount keeps the opened distribution door attached to the hopper or chassis, reducing dust, damage, and handling time.

Vacuum needles and robot positioning automate seed and growing-medium placement, reducing labor in capsule production.

Sensor-guided calibration during travel helps agricultural applicators correct motion-related measurement errors without stopping.

Load cells and a variable-position gate regulate seed output continuously, reducing manual calibration and minimizing hopper-system floor space.

Wireless control calibrates hopper-gate minimum and maximum flow rates, reducing machine-to-machine variation and compensating for component wear.

Flexible upper and lower sections let the drop tube navigate crop rows while directing fertilizer downward for controlled placement.

A connecting-plate hinge combines actuator-driven folding, breakaway release, reset, and damping for protected boom operation.

A cylindrical rotary slide valve adjusts outlet areas to distribute conveying air across seed and fertilizer metering lines.

A seeding machine adjusts sowing timing using inclination data to maintain precise seed spacing along the working direction.

An adjustable seed dispenser accommodates varying seed sizes while a vibratory aerator removes soil plugs to enhance root growth.

Enclosing the central chamber with wing portions and a bottom wall prevents mud ingress into outlet openings during wet field operations.

Manifold splits blower air flow into individual streams for parallel rigid tubes, ensuring uniform distribution across larger boom sizes.

A seed retrieval apparatus uses vacuum sources to draw discard seeds through dedicated tubes into separate containers for each row planter.

Segmented feed disc recesses smooth pulsing seed flow and reduce vibration effects for uniform canola spacing.

Segmented agitators driven by a controller using meter speed data resolve energy waste from single-motor designs.

A centrifugal spreader control system uses radar sensors to detect distribution characteristics and automatically adjust disc speed.

A system calculates an expected planting quality indicator by combining GPS and weather data to guide planter adjustments.

Controller detects configuration changes to adjust tire pressure, reducing soil compaction during field operations.

Piezoelectric sensors mounted on deflector exteriors detect mechanical vibrations from material flow to monitor delivery tube status.
