Harvesters TRIZ Cases

Wheel acceleration is varied from steering input rate so left and right hydraulic drives respond more naturally to operator commands.

UV-B seed priming replaces chemical treatments to boost stress tolerance, growth, and crop yield with a safer pre-sowing approach.

A synchronized paddle mechanism keeps buttlifter paddles clear of the ground, enabling a more horizontal basecutter for cleaner sugarcane cutting.

Ball-jointed support arms let the deflection shaft tilt under uneven crop flow, reducing bearing stress and wear in harvester conveyors.

Counter-rotating rollers and a guide strip leaves from plant stalks continuously, cutting labor and machine complexity while handling multiple plants.

Dirt removal openings in feeder slats clear debris above sprocket teeth, preventing chain jumping, wear, and downtime in combine harvesters.

A spring-linked stationary shaft absorbs peak loads from thick crop and foreign objects, protecting controlled tines and the crankshaft.

Controlled pivoting reel tines fold upward under heavy crop piles to cut force peaks while preserving crop conveyance and reducing grain loss.

Partial bale compression prevents air channels and guides airflow through lower and upper ducts to deliver more uniform moisture content.

A variable-length energy store lets reel tines yield under heavy crop loads, reducing permanent damage and reel weight.

A pivoting tine carrier with a variable-length energy storage element absorbs peak reel loads, limiting tine deformation, weight, and soil compaction.

A pivoting stone trap with a one-hand front flap eases emptying and opens front access for threshing concave segment removal.

Independent stalk roll speeds improve axial corn stalk shredding, expose pith for faster decomposition, and avoid confetti-like residue.
