Sowing TRIZ Cases
- Sliding Air Line Connector With Rotation-Independent Locking
A cam-actuated sliding connector locks air lines without tools, reducing leakage, corrosion, and connection time in air seeder systems.
- Composite Fertilizer Elbows With Wear Plate Flow Deflection
A polymer elbow with an embedded wear plate redirects abrasive fertilizer flow, resisting corrosion and reducing transfer-line wear.
- Seed Flow Sensing Using Sensor Duty Cycle in Air Seeders
Duty cycle from optical seed sensors is used to estimate particle frequency and flow rate, improving accuracy for high-flow crops without larger sensors.
- Planter Path Planning With Exclusion Zones for Overlap Avoidance
Path interference estimation creates local exclusion zones so planters avoid overlap, reduce seed waste, and protect yield in buffer areas.
- Optical Bulk Solids Metering for Stable Column Flow Control
Optical speed sensing and a conical obturator keep granular solids in stable column flow while detecting plugging or empty conditions.
- Field Application Planning Using Remote Sensing and Local Dosage Control
Remote sensing and local field sensors guide zone-specific dosing of crop inputs, cutting waste and resistance risk while supporting yield.
- Site-Specific Agricultural Planning Using Remote and Field Sensors
Combining satellite imagery with local field sensors enables precise, site-specific application of nutrients and crop protection agents.
- Hydraulic Pump Compensator Assembly for Highest-Load Pressure Control
Electronic pressure and flow compensator valves regulate swash plate output from the highest load pressure to reduce engine load and fuel use.
- Planter Path Planning Using Interference-Based Exclusion Zones
By estimating interference between planned planter passes, this case sets local exclusion zones to protect seeds and avoid wasted crop inputs.
