Lawn-Mowers TRIZ Cases

A trimmer head with a hub-and-spoke design stores line in the hub and routes it through spokes to maintain cutting efficiency.

A robotic garden tool manual blade height adjustment mechanism uses a cam interface to convert actuator rotation into axial blade movement.

Handle-mounted speed setting device with differentiated operation buttons enables variable rotational speed control of electric mower cutter blades.

A humidity sensor adjusts a lawn mower shutter to vary transport air flow velocity, preventing uneven grass clippings distribution in the receptacle.

An obliquely angled blower draws cut vegetation from under a cutting deck and directs debris into a collection unit.

A pivotal blower platform with elongated nozzles directs air downward to disperse grass clumps on riding mowers.

A lawn mower control unit adjusts drive speed and flap angle based on detected grass clippings weight changes.

A control unit obtains two-step battery voltage values to determine optimal charging station return timing.

Clamping mechanism secures adjustable platform to mower deck without tools, eliminating modification requirements.

Segmented disk guards absorb impact forces from obstacles, protecting cutting disks while distributing stress across the modular assembly.

A garden tool power source compartment features a dedicated drain aperture with an automatic stopper mechanism.

A control unit adjusts rotary member output during rotation to maintain consistent cutting height across uneven terrain.

Blade repositioning mechanism contacts housing-integrated grindstone, eliminating manual cleaning labor and preventing grass damage.

Spiral lifting blades on the cylindrical drum elevate cut plants before wrapping occurs, ensuring efficient material flow and reducing machine overloads.

A double deck boot attachment slides a smaller unit inside a larger one to create a single compact assembly.

Acute angled guide wall intercepts grass clippings between intersecting cutting chambers to create turbulence and chaotic distribution.

A convertible mower pivots its handle assembly forward to enable a ride mode.

Pivoting the handlebar vertically into a locked maintenance position clears cutting element access while minimizing storage volume.

Steel fins on the scrub claw alert drivers to hidden rocks and stumps, preventing blade damage during high-speed mowing.

Segmented control modules isolate power distribution for traction motors and implement actuators, reducing specialized diagnostic tool requirements.

A lawn mower controller uses a telescoping shaft to enable user operation from a stationary position, reducing physical exertion.

Automatic calibration of individual wheel hub motor speed resolves hydraulic inefficiencies by adjusting command speeds via rolling radius offsets.

A mower handle rotates between operational and storage positions while a control system monitors its location to manage motor activation.

A combine harvester header integrates a second cutter bar for cutting remaining stalks at a lower height.

A pivot mounting rod with bushing and hook attaches collection tubes to mower decks, replacing elastic straps that lose tension over time.

A tractor-mounted brush clearing assembly uses a hooking unit that slides laterally along bush trunks to extract vegetation.

A protective cover drapes over the rigid frame to shield the knife assembly from debris.

Hybrid power system supplies DC or AC energy to an electric mower chassis while adjustable handle mechanism accommodates user stature.
