Lawn-Mowers TRIZ Cases

Closed-loop blade-speed feedback adjusts the electric mower’s blade carrier to match grass load, balancing cut quality and battery consumption.

Learn how conical extension surfaces distribute loads in a lawn mower blade, reducing blade load by 5% to 20%.

A single bell-crank and linkage assembly synchronizes all four wheel heights without disturbing drive-chain or belt tension.

Complex belt routing can make multi-blade mower units bulky and limit lift travel; a planar band layout reduces height and weight.

A vertically separated first and second cutting portion distributes grass cutting across the blade assembly, reducing motor load and extending battery life.

A centrifugal transmission member locks or releases the trimming head at a preset line-length threshold, enabling automatic feeding with less waste.

Separate carrier-frequency settings let one controller tailor PWM signals for two motors, reducing switching-element heating, torque fluctuations, and audible noise.

Elastic deformation replaces pivots, bushings, and springs in handle controls, reducing parts while preserving control motion.

Mixed bolt-and-hook fastening secures the rotor cover while reducing tool-required locations during maintenance.

Centripetal force moves the cutting members into position, while pivoting away from hard objects helps preserve sharpness and prevent damage.

A pivoting rear roller and spring-biased brackets help a mower deck maintain cutting height over bumps and prevent high spots in grass.

A movable protecting wall keeps the cutting mechanism out of reach while lifting for grass and obstacle clearance.

A movable control stop lets the deck rise over uneven terrain while limiting downward travel and preserving set height.

Branch water pipes direct cleaning flow to mower housing corners, improving wall cleaning while protecting the discharge section.

This case uses an asymmetric outer grip, circular inner surface, and pivoting bar to improve comfort and variable mower control.

This knife holder shifts between trap and release positions, securing knives during mowing while simplifying tool-less replacement.

A mower-driven pulley and hinged angle bar add angled trimming without stopping to switch from the riding mower.

A linked chute and blocking plate reposition discharge and close the outlet, improving mower access near edges and narrow openings.

A mechanical lock blocks trigger operation when the handle is non-working.

A movable handle grip, position sensor, and controller create feedback-based mower speed adaptation to the user's walking pace.

This case shows how angled intake and curved surfaces redirect turf clippings rearward while retaining kinetic energy and limiting backup.

An inclined top baffle guides mower clippings through an inverted L assembly, extending throw distance and reducing lawn re-deposition.

This case shows how segmented blade geometry creates whirling airflow to lift flattened grass and prevent clipping clogging.

This case integrates a load deck with the mower’s front wheel frame to transport heavy landscaping materials without separate equipment.

A motor case and separate battery attachment points spread loads, reducing housing size and weight while protecting the battery.

One modular electric vehicle handles turf tasks with interchangeable implements and lower noise.

Sensors reposition rotary blades around posts, reducing manual trimming and herbicide use.
