Lawn-Mowers TRIZ Cases

Movable support legs pivot a lawn mower hopper to resolve the contradiction between high dump capacity and obstructed operator visibility.

A drive system halts a reciprocating sickle bar at a predetermined position to simplify blade replacement.

Independent pivoting limiters prevent downhill twisting while allowing uphill turning, reducing uncut grass strips and turf damage.

Distinct aperture shapes prevent misalignment and secure attachment on mower blades.

A mower deck linkage system rotates support arms in unison via a single actuator to adjust cutting height.

A robotic garden tool system defines temporary working areas to guide movement direction and maintain position within designated zones.

A control assembly uses independent levers to switch between front, rear, and all-wheel drive modes on a walk-behind mower.

Reel-mounted wipers clear crop dividers of accumulated plants, preventing hairpinning blockages that disrupt continuous crop flow into the header.

An automatic suspension adjusts spring preload via a load sensor and controller, resolving the trade-off between adaptability and device complexity.

An automated travel drive system replaces manual pushing with a displacement sensor detecting user input to adjust speed dynamically.

Controller stops motor energization before clutch engagement to eliminate abrupt current increases and extend operation time without large batteries.

A rotary trimming attachment uses a rotator mechanism to dynamically adjust cutting head orientation relative to vehicle travel direction.
